TITLE: CROWD MANAGEMENT - INSTRUCTOR NOTES
The purpose of this block of instruction is to familiarize the student with the organization,
development, and proper execution of riot control, dispersal, and arrest techniques. Crowd dispersal
and arrest exercises will provide the student with the basic skills to safely and successfully participate
and conduct similar operations in their jurisdictions.
Careful planning and coordination of events cannot be overemphasized. This is particularly true
during mock riot or mock civil disturbance and arrest exercises. Due to the number of students
playing the role of officers and the number of others playing the role of an unruly crowd, it is
recommended that a safety monitor be appointed to work with the role players of the unruly crowd,
while the instructors work with all the students.
If possible, it is recommended that the students be exposed to live chemical munitions while the
mock riot exercises are being conducted. If live chemicals are not used then inert agents should be
used. It is important that safety devices to protect the eyes and facial areas be provided to the role
players.
Please refer to the practical exercise guidelines.
Instructors should review all applicable OSHA regulations for gas mask and other munition exercises.

PRACTICAL EXERCISE GUIDELINES: PASSIVE PROTEST
A.
Purpose
These exercises are intended to provide the students with an opportunity to observe,
practice, and perform the following training objective:
Be able to properly handcuff, lift, and transport a passive protestor by using
flexcuffs and stretchers.
B.
C.
D.
Exercise Conditions
1.
These exercises should be conducted after the classroom lecture has been
completed and prior to the exposure to any chemical agents.
2.
These exercises should take approximately 15-30 minutes depending on class size.
3.
These exercises can take place either outdoors or indoors.
4.
All students should participate in these exercises.
Personnel and Equipment
1.
One primary instructor can conduct these exercises.
2.
At least one stretcher is needed for the entire class.
3.
Each student should have at least two flexcuffs in order to participate in these
exercises.
4.
One set of cutters is required.
Procedures for Conducting This Exercise
1.
Divide the students into equal groups and pair off into arrest teams.
2.
Give specific instructions of how to use flexcuffs and how to properly pick up a
stretcher.
3.
Lay the stretcher out in front of one group.
4.
Have one student act as a passive arrestee by sitting on the ground with legs
crossed.
Using two arrest teams at a time, have students take turns placing flexcuffs on the
arrestee, placing the arrestee on a stretcher, and carrying the arrestee to another
group.
5.

6.
Group two then performs the same exercise.
7.
Continue until all students have rotated through the exercise.
NOTE: In order to save time, each student in the arrest team can place
flexcuffs on the arrestees. Therefore, the arrestees will have two sets of
flexcuffs on his/her wrists.
E.
Evaluating the Exercise
The instructor should evaluate the student=s performance based on the following:
1.
Proper use of flexcuffs, i.e., proper position on wrists, proper restrictiveness (not
too loose or too tight).
2.
Proper lifting techniques, i.e., lifting with legs and not back.

PRACTICAL EXERCISE GUIDELINES:
FORMATIONS, CHEMICAL AGENTS AND MOBILE TACTICS
A.
Purpose
These exercises are intended to provide the student with an opportunity to observe, practice,
and perform the following training objective:
Demonstrate proper crowd control formations, using the riot baton, shields, and the
use of mobile tactics.
B.
Exercise Conditions
1.
The exercise should be conducted after the classroom lecture has been completed.
2.
A specific site location is required for the exercises. A street location is the best
site, however, an open field or parking lot may be used for traditional foot
formations. A paved area must be used for mobile tactics.
3.
Students need one hour of practice and familiarization time to become accustomed
to the various offensive and defensive techniques associated with the use of riot
batons and shields.
4.
The instructor should have a pre-planned idea about what type of scenario should be
given to each respective team based on the tactic used.
a.
Traditional crowd dispersal operation using the riot baton. (Time - 30
minutes)
b.
A second scene should be conducted with the aid of inert chemical agents.
(Time - 30 minutes)
c.
A third experience should be conducted using the riot shield, associated
with arrest teams movement. (Time - 30 minutes)
d.
The gas mask procedures should be initiated at various stages of the
exercise to give the student the opportunity to perfect masking and
unmasking skills.
e.
Mobile tactics require the operation of police vehicles and should not be
conducted until the students have completed defensive driving. This
segment is divided into four distinct exercises. (Time required - 2 hours)
(1)
Field force mobile response requiring students to move with their
vehicles as a unit, and then dismount and form up using traditional
crowd control formation.

conjunction with formation movement.
(3)
Mobile rescue techniques demonstrates the three unit L.A. Model
and the two unit Miami Model.
Arrest teams working in conjunction with the various formations should be
utilized to show the student the efficiency of unit action. (Time - 1 hour)
Chemical Agents: A demonstration of the various chemical agents used for crowd
control and dispersal operation should be demonstrated under field conditions. This
allows the students to see and experience first hand the effects, capabilities, and
limitations of the various systems and munitions. This exercise includes the
controlled exposure exercise and decontamination time. (Time - 2 hours)
Personnel and Equipment
1.
One primary instructor can conduct the classroom lecture and direct the student
exercises outdoors.
2.
The field exercises will require an additional instructor to monitor the role players
and assist in coordinating the various field elements.

2.
Divide the students into squads of eight to twelve in each squad.
Arrest teams should be designated and should consist of no less than three students
and no less than six students.
3.
Students should be divided into two groups when conducting unprotected chemical
exposure. One student is masked while his/her partner is unmasked. This is
necessary for safety reasons. Once the first student has recovered from the
exposure, then switch roles.

Introduction
A.
Opening Statement
NOTE: Reveal opening slide ACrowd [email protected]
Freedom of speech and the right to lawful assembly are guaranteed by the First
Amendment of the United States Constitution. Similarly, every state in the Union by
its constitution, protects these rights. Unfortunately, our history is marked with
incidents where these rights have been abused, resulting in mobs and riots that left
death and destruction in their wake.

Reasons
NOTE: Click on right arrow to reveal ATasks may range . . [email protected]
In day-to-day activities the officer will find himself engaged in duties related to
crowd control. These tasks may range from controlling a curious group of
bystanders at the scene of an accident to the possibility of a hostile crowd bent on
riot and destruction. The officer must be equipped with knowledge to handle this
wide spectrum of protection of life and property.
II.
Body
A.
Crowds
1.
As law enforcement officers, we generally view our actions as one-on-one
with those persons who break the law. We must learn to see our actions on
a broader plane, especially when taking action in a group setting. Actions
taken by an individual officer--right or wrong--can be viewed negatively by
a group and ultimately lead to civil unrest. Officers should not ignore
unlawful behavior, but should use tact and diplomacy when confronted by a
crowd.
This lessens the possibility of hostile group attack and gives the officer time
to consolidate resources to help diffuse or disperse a crowd before a
problem develops.
2.
A crowd is best described as a number of persons temporarily congregated
in an area. Crowds form for many different reasons. Individuals usually
Basic Law Enforcement Training
Hypermedia
10
Crowd Management
have no common bond other than their curiosity of an event. There are also
planned crowd activities such as political rallies.
3.
B.
Normally, crowds are orderly, lawful in their actions, and not endangering
life or property . This type of crowd situation does not present a major
problem to law enforcement officials.
Types of Crowds
NOTE: Click on right arrow to reveal [email protected]
NOTE: Click on word [email protected] to reveal text; click on text to make it
disappear.
1.
The physical crowd
a.
A physical crowd is characterized by density of contact and
showing no significant group behavior. The physical crowd has
little or no organization, no unity of purpose, and its members come
and go. (Example: mall or major festival type event)
b.
One type of physical crowd is the conventional crowd or casual
crowd. This crowd is characterized by density of contact showing
no significant group behavior. They are, however, usually
assembled for a purpose but have no common bond and are not
dependent on each other.1
NOTE: Click on word [email protected] to reveal text; click on text to make it

2.
The psychological crowd
The psychological crowd is an assemblage of people who have a sustained
common interest and respond emotionally to the same stimuli. (Example:
ball game, political speech, parades, fires, accidents or disturbances)
Types of psychological crowds
a.
Sightseer or sightseeing crowd
This crowd is characterized by their common bond (a single
purpose for being at a certain place). They are curiosity seekers,
mostly cooperative, and sometimes anxious to assist. Officers
must retain their cooperation while attempting to disperse them.
Basic Law Enforcement Training
Hypermedia
11
Crowd Management
b.
Expressive or agitated crowd
Members of the expressive crowd are involved in some kind of
Aexpressive behavior,@ such as a block party or political rally. This
type of crowd is emotionally involved and can easily become
agitated if approached improperly. For the most part, they want to
Ahave a good [email protected] or express their point of view. If possible, and
as long as there is no breach of peace, it is best to let the crowd
release their energies by permitting them to express themselves.
Officers must be aware of the emotional climate of this group in
order to find a way to reduce the emotional level and successfully
disperse the crowd. Otherwise, officers risk the possibility of
turning the crowd into an aggressive and destructive mob.
Expressive or agitated crowds are an unorganized group of people
willing to be led into lawlessness but hesitate to act because it lacks
(1) organization, (2) courage, and (3) unity. They are noisy,
willing to threaten and taunt or harass police; however, they refrain
from physical attack.2
3.
Mob (hostile/aggressive)
A mob is a crowd whose members, under the stimulus of intense
excitement and agitation, lose their sense of reason. They can also lose
respect for sense of order, law, and respect for each other.3
NOTE: Click on right arrow to reveal ATypes of [email protected]
Types of mobs:
a.
Escape mob
A highly emotionally charged crowd driven by fright describes the
escape mob. People involved are driven by an overpowering fright
which creates an emotional, unreasonable, and frantic behavior
driving the crowd to seek safety. This type of mob is extremely
difficult to control because the group, even though together and
acting as one, is interested in individual survival.
b.
The aggressive mob
This is a mob that will attack, riot, and terrorize others. The aim of
the mob is the destruction of property and physical attacks on
persons.
c.
Acquisitive mob
Basic Law Enforcement Training
Hypermedia
12
Crowd Management
This a mob who has the desire to acquire something. (Example:
food or merchandise as in the looting type mob)
d.
Expressive mob
The expressive mob is a group expressing intense feelings or
revelry. Usually follows some special event. (Example: New
Year=s Eve, major sporting event such as the Detroit Pistons riot on
June 16, 1990, when seven were killed during the crowds
rampage.) This type of mob can be very destructive. 4
C.
Social/Psychological Influences
Psychological behavioral factors are present in any crowd confrontation. These
factors affect the crowd as well as law enforcement personnel. Knowledge and
appreciation of social/psychological influences can help control forces effectively
counter riot tactics, help with crowd dispersal, and help supervisors maintain control
of their subordinates.
These behavioral factors not only affect a crowd, but they affect control forces as
well.
NOTE: Click on right arrow to reveal ACrowd Behavioral [email protected]
NOTE: Click on first hand icon.
1.
Anonymity
The feeling of being lost in the crowd. Members of the crowd feel they
cannot be identified. Therefore, they lose responsibility for their actions.
NOTE: Click on second hand icon.
2.
Universality
The Aeverybody is doing [email protected] feeling. Members feel the attitudes and
emotions are being experienced and are shared by everyone in the group.
NOTE: Click on third hand icon.
3.
Inability to withdraw
Being afraid to express a view contrary to those in the majority.
NOTE: Click on fourth hand icon.
4.
Increased hostility (Convergence Theory)
Basic Law Enforcement Training
Hypermedia
13
Crowd Management
When people are frustrated and believe they are being treated unfairly,
confrontation is an outlet for their anger; however, conflict does not
eliminate the problem and it often increases hatred between social groups.
According to this theory, people merely reveal their true selves in a crowd-the crowd serving only as excuse or a trigger.
NOTE: Click on fifth hand icon.
5.
Social suggestion
The urge to do what others do is quite strong with the majority of people.
Crowd people tend to follow the lead of others, particularly those designated
as leaders. Those involved usually have a common denominator that brings
them together to unify the group.
NOTE: Click on sixth hand icon.
6.
Emotional contagion (Contagion Theory)
This is the most dramatic feature of collective behavior where excitement
seems to be [email protected] from one person to another. Emotional contagion
provides the crowd with psychological unity and the point at which a
crowd or assemblage becomes a mob.5
D.
Role of the Rumor
NOTE: Click on right arrow to reveal ARole of the [email protected]
The rumor is the characteristic mode of communication in a collective behavior
setting. Rumors can be defined as communication through people caught up in an
ambiguous situation who try to make a meaningful sense of it by relying on their
perceptions and intellect.
1.
A rumor is a progressive distortion of an originally accurate statement.
2.
Rumor plays a major part in crystallizing public opinion.
3.
Some experts have said that no riot takes place without a build-up through
rumor.
4.
Animosity is gradually intensified preceding a riot by stories of aggressive
acts on the part of the opposition.
5.
Rumors often follow controversial encounters between a member of a
minority group and a white police officer. These rumors are often more
important than the incident.
Basic Law Enforcement Training
Hypermedia
14
Crowd Management
Example: The Watts Riots of the 1960's began because of a [email protected]
police were beating a pregnant black [email protected] The facts were that an
arrest had been made, but the arrestee was neither pregnant nor was she
beaten. Subsequent confrontation between citizens and the police lead to
further confrontations where the police either withdrew because they were
not prepared to deal with the crowds, or they were made to appear helpless.
6.
E.
Rumors must be countered! When a rumor begins to surface, every effort
must be made to communicate the truth. This can be accomplished by
effectively using community contacts, i.e., community advisor , community
leaders, community policing efforts, and the press to get the facts out into
the community.
Types of Disturbances
There are five (5) general types of disturbances and civil unrest which may be
confronted by law enforcement officers.
NOTE: Click on right arrow to reveal ATypes of [email protected] Items listed
below will appear in animation and automatically.
1.
Mass demonstration
This type of demonstration usually involves hundreds or thousands of
people, many of whom may be nonviolent and within their rights to protest;
but because of their numbers, they can overwhelm the capabilities of law
enforcement agencies. (Example: protest march)
2.
Civil disobedience
This involves a group that is usually nonviolent and uses tactic and posture
that place them in a position to be arrested by law enforcement agencies.
This places the law enforcement agency in a very awkward position
because of the nonviolent approach taken. It is usually a highly visible
action and often has extensive media coverage. (Example: operation rescue
demonstration, student takeovers on college campuses)
3.
Labor disorder
a.
Picket lines
Most unrest and violence relating to a labor dispute traditionally
center on the picket line activity. The most common forms of
labor violence are scuffles at picket lines between strikers and
nonstrikers. Violence may involve threats and intimidation as well
as some physical form of attack.
b.
Transportation dispute
Basic Law Enforcement Training
Hypermedia
15
Crowd Management
In a labor dispute involving the transportation industry, the violence
may be more widespread and incidents may occur incidentally or
simultaneously in a very wide geographical area.
4.
Idealistic protest
These usually involve fanatically dedicated participants, usually young males
who are not deterred by the threat of arrest or use of force.
5.
Riot
A riot is an uncontrolled and violent disturbance of the public peace by three
or more persons joined together for a common purpose. (Example: recent
L.A. riots)
a.
Conventional mob riot
This classic type of riot is the climate of violence which is caused
by the rampage of a spontaneously formed mob.
b.
Race riot
A Atrue race [email protected] is open warfare between those of different ethnic
or religious groups. Rumor plays a key role in this type of riot-used to influence. Once the stage is set, only a spark (incident) is
required to ignite the group into a bloody war. The target is the
[email protected] group. Traditional crowd/riot control techniques have
limited effectiveness in this setting because law enforcement is
usually caught between groups who may be armed.
c.
Organized/Planned riot
A planned riot occurs when a mob is deliberately assembled and
incited to riot. They utilize a key instigator with predetermined
followers. They are used to enhance the ideas of the instigator and
destroy the police department=s reputation. As a result, the public
loses faith in the police, which hurts police morale and makes them
hesitant and unsure of themselves.
Basic Law Enforcement Training
Hypermedia
16
Crowd Management
d.
Guerrilla riot
Their actions are not those of the mob but rather those of a
guerrilla army or terrorist group. Their prime target is the police,
and they use ambush techniques to accomplish their goals.
Conventional riot control countermeasures are useless in this type
of encounter. This is true urban warfare involving guns, grenades,
explosives, etc.
e.
Spontaneous riot
Confrontations just don=t happen. Some force or event must occur
to Aset [email protected] a group. Officers responding to loud party calls or to
gatherings outside night spots can become targets, particularly if
the officers= actions are viewed as improper by the group. Such
actions may be a simple arrest, closing down a loud party, or
clearing the street.
Note: In 1964 and 1965, the Rochester, Pennsylvania and L.A.
Watts Riots were all ignited from [email protected] police arrests on busy
streets where crowds spontaneously gathered and fused together.
These incidents occurred rapidly; however, they did not erupt into
widespread civil unrest for hours. In contrast, today=s incidents
grow out of control in as little as 15 minutes. The 1992 L.A. Riot
that began at the intersection of Florence and Normandy spread
rapidly through the city=s south side. 6
NOTE: Show video Anatomy of a Riot (44 minutes). Discuss
the scope of attacks on people and how they changed from
beating to killing those singled out for the attack.
F.
Mental Preparation of Officers
A special need exists to prepare individuals for the mental and physical stress of civil
disturbance control operations. Officers must be made aware of the influence of
psychological factors upon their own behavior.
Basic Law Enforcement Training
Hypermedia
17
Crowd Management
1.
Individual response to stress
Officers engaged in civil disturbance operations will encounter the noise and
confusion created by large numbers of people facing them. Individuals may
shout at, insult, or call officers abusive names. Officers must learn to
ignore these taunts and not allow personal feelings to interfere with the
execution of their mission. In addition, officers can expect objects to be
thrown at them, but must learn to avoid thrown objects by evasive
movements. They must never throw the objects back. Officers must
subdue their emotions and carry out their orders determinedly and
professionally.
NOTE: Make a point that officers should understand that the welldisciplined execution of orders is the most effective force applied
against rioters.
2.
Psychological influences
Just as the crowd may be swept into violence by various psychological
influences, the reaction of officers may be inappropriate because of the
same factors. Both the law enforcement commanders and the officers
must be aware of these factors so that they can cope with them in the civil
disturbance environment.
G.
a.
The cumulative effect of these psychological factors may be an
excessive response by officers who are often thrust into situations
with little time to brief them about the situation.
b.
The fatigue factor must also be taken into consideration in
determining the ability of the control force personnel to deal with
provocation. In situations where the control forces become
extremely emotionally involved, the supervisors may lose control
over the officers= actions.
c.
Emotional involvement - Officer focuses in on one demonstrator
and targets this person for uses of force and/or arrest. Supervisors
must be vigilant for such behavior and pull these officers off the
line and put them in a support role, until they regain their
composure - Aa cooling off [email protected]
Estimating Crowd Size
NOTE: Click on right arrow to reveal AEstimating Crowd [email protected]
The development of an accurate crowd estimate is an important part of
demonstration control. Since the demonstration to some extent is a media event
designed to call public attention to a cause or controversy, its success or failure may
Basic Law Enforcement Training
Hypermedia
18
Crowd Management
tend to be measured by the number of participants it was able to attract. Under
these circumstances, widely divergent estimates of crowd size might be expected
from sources either in support of or in opposition to the demonstration. Therefore,
journalists turn to the police for professional, objective estimate of crowd size.
If the crowd estimate results in numbers that either exaggerate or belittle the
demonstration, citizens may feel that the police are biased on the issue and have
betrayed their professional objectivity.
Accurate crowd estimates are not difficult to produce--whether the method for
producing the estimate relies on a single experienced observer or makes use of aerial
reconnaissance and skilled photo interpreters, ultimately the process comes down to
counting and multiplying within a set of reasonable variables.
1.
The mobile crowd
An observer is stationed at a convenient location along the parade route.
The number of persons in each of the first few ranks of the parade are
counted as they pass in order to establish an average. The total number of
ranks is then recorded as the parade passes. If the parade thins out toward
the end, the number of persons per rank is adjusted accordingly.
The total number of parade ranks is then multiplied by the number of
persons per rank, and the crowd estimate is complete.
It is preferable to use two observers stationed at different positions along
the parade route to obtain the crowd estimate. The two totals are compared
and evaluated before an official figure is released.
2.
The stationary crowd
Stationary crowd estimates are more difficult. Sometimes the geographic
configuration of the meeting place can make the crowd appear to be larger
or smaller. For example, a favorite spot for outdoor political speeches near
the Capitol Building in Washington, D.C. is a natural bowl which requires
viewers to assemble in ascending ranks on a grassy slope before the
speaker. When televised from this perspective, crowds appear to be much
larger and more impressive.
Estimating the stationary crowd is also basically a matter of counting and
multiplying. When the crowd is relatively small, perhaps up to 1,000
persons, the estimator simply counts to some workable number like 50
persons, locks an imaginary frame around the space occupied by that
number of persons, then proceeds to count the time that he can move that
same imaginary frame over the entire crowd. Ten frames equal 500, and so
on.
Basic Law Enforcement Training
Hypermedia
19
Crowd Management
When the crowd is larger, it is preferable for the estimator to work with a
fixed frame or fixed grid, in which the crowd is estimated relative to its
density within that known space. The grid, for instance, might be projected
as the size of a football field or a basketball court or the length of a city
block.
Experience with these known space grids in various cities has produced
some formulas for estimating crowd size relative to density within the grid.
For example, a densely packed crowd is one in which five persons occupy
each square yard of space. A densely packed crowd occupying the length
of a city street for one block will number approximately 10,000 persons. A
loosely packed crowd, in which one person occupies each square yard, will
fill up the same city street with just 2,000 persons.
The ideal means for observing and estimating large crowds within grids is
by aerial reconnaissance, probably by helicopter. Observers positioned atop
a building in the assembly area can approximate the accuracy of a helicopter
observation. Lacking even that opportunity, a high ground or elevated
position should be sought.
The figure shows estimates of crowd size relative to density within several
known grids.
NOTE: Refer to handout, ATable for Crowd Size [email protected]
When a large demonstration is expected and assembly ground has been set
aside as a result of cooperative negotiation, measured grids can be marked
in advance in such a way as to assist observation by helicopter or from
some other vantage point.7

Crowd and demonstration control
NOTE: Click on right arrow to reveal a portion of the paragraph
below.
A crowd generally is aware of the law and usually respects the principles of
law and order. However, often emotions become so high that they overrule
order. In confronting a crowd, law enforcement should know the reason
for the meeting, determine the general characteristics of the individuals (and
the crowd), and know well the area in which the crowd gathers.
One popular method of controlling factors which affect emotions is to have
a permit system for the registering of meetings and assemblies. In a permit

Crowd Management
system, organizers must apply for a permit in order to hold meetings or
gatherings. In such a situation, the permit issuers (often a law enforcement
agency) can set rules and regulations for these meetings that must be
followed or the permit may be canceled. Certain elements, such as those
discussed below, can be controlled in an effort to prevent their effect on the
emotions of the crowd at the meeting. Promoters and organizers can be
held legally responsible for the group=s behavior. This encourages the
organizer to [email protected] his group to ensure a peaceful meeting.

A riot is mob violence, a contagious striking out at authority and the
symbols of authority. It may consist of indiscriminate looting and
burning; it may be open attacks on officials, buildings or innocent
bystanders; or it may be both. Law enforcement must control
group violence. Law enforcement, therefore, must be carefully
instructed about the kinds of violence they may encounter.

Law enforcement operations at a strike scene
a.
Dynamics of labor disputes
The dynamics of a labor dispute are very complex. To better
understand the related law enforcement problems involved in this
duty, officers should look at several perspectives: free speech,
police power at the scene, picketing, employer and nonstriking
employees, and access to company property.
Basic Law Enforcement Training
Hypermedia
23
Crowd Management
b.
(1)
The right of strikers to picket is protected by the courts on
the ground that it is a valid expression of freedom of
speech.
(2)
Exercise of the police powers must be reasonable in
relation to the actions which it is designed to combat, and
must be neither arbitrary nor discriminatory.
(3)
An employer and his employees who do not strike also
have rights to be protected. Under North Carolina law,
employees do not have to join a union to be employed or
continue to work; therefore, they have a right to work
without interference from striking employees.
(4)
The law is clear that an employer has the legal right of
ingress and egress to and from his premises without prior
consultation with the picketers; employees, customers, and
others seeking to enter or leave the employer's premises
also have the right to do so without interference from the
picket lines.
Duties of law enforcement
It is the duty of law enforcement to see to it that the strikers' right
to picket and make known their grievances in a legal manner is
protected; to see that persons are able to freely exercise their right
to enter and leave company premises at will and without regard to
the existence of a strike; and to maintain the peace and protect the
rights and property of all persons involved.

Crowd Control Operations
There are four (4) crowd control options available based on the desired objective. A
prime consideration in selecting an option(s) will be the effect of the response in
reducing the intensity of the existing situation.
NOTE: Click on right arrow to reveal ACrowd Control [email protected]
1.
Monitor
This option consists of watching the crowd=s progress and development by
control force teams. Monitoring enables the agency to gauge the crowd=s
activity and intent in relation to civil disturbance and possibly influence their
actions through persuasive means.
This option is particularly appropriate for large non-violent demonstrations
where more decisive action is not feasible because of the crowd size and
where the intensity of the situation might escalate. This option is also
appropriate as an interim measure pending arrival of additional control
forces.
Techniques for accomplishing this option include passive observation of the
crowd and communication with leaders on the intent or interest of the
group. If the crowd is not out of control, officers should monitor the area
to identify leaders and group actions, and to discover possible dispersement
alternatives.
2.
Containment
Basic Law Enforcement Training
Hypermedia
27
Crowd Management
This option consists of restraining a large number of individuals within the
area they are presently occupying, thereby containing any further aggressive
activity. This option would be appropriate in college campus situations to
prevent demonstrators from spreading out to surrounding communities and
to prevent unauthorized personnel from entering the campus.
3.
Blocking
This option consists of the physical denial of a crowd=s advance upon a
facility which is the potential or actual target to dissident activity. Crowd
control formations (especially the Askirmish [email protected]) and barricades are the
most appropriate techniques for this option. Barricades such as vehicles,
traffic barrels, and water or sand-filled barrels can be erected to block or
channel the movement of crowds. These devices and water or sand-filled
barrels can be erected to block or channel the movement of crowds. These
devices, when used in combination with control forces and other crowd
control techniques, are useful in accomplishing containment or blocking.
4.
Dispersion
This option consists of action taken to fragment a crowd and is especially
applicable to small crowd situations in a congested urban environment.
This selection should include the consideration that such dispersion may
increase and spread lawlessness rather than reduce it. Therefore, one
should establish control over the dispersal routes; provide security for those
facilities that might become likely targets for small groups; and then prepare
to follow-up the dispersal operation with the apprehension of small groups
still active in the area.
Techniques for accomplishing dispersal objectives would include the
proclamation, show of force, use of crowd control formations, and the use
of riot agents and saturation patrol techniques.

Use of Force
The amount of force used to quell any civil disturbance must be only that force
necessary to overcome the actions of the crowd. It is through the controlled
application of force that a crowd is dispersed or a disturbance ended. Indiscriminate
use of force upon a crowd should never be tolerated or condoned.
Regardless of the type of demonstration, the amount of force used must be:

2.
Necessary
3.
Lawful
The force should be applied only long enough to overcome the resistance of another
person's force. 9
Example: A riot may require an officer to use either a baton in a striking or thrusting
motion or chemical agents. On the other hand, passive/resistant demonstrations
may require officers who physically carry the demonstrators away.
K.
Large Scale Disturbances
Large scale disturbances utilize the same techniques as small scale disturbances.
The important point between the two is that large scale disturbances require more
control force personnel. Supervisors should never attempt to disperse a large crowd
with a small number of officers.
If there are insufficient control forces on hand to disperse the crowd, efforts should
be made to monitor and contain the crowd as well as possible until additional control
forces are summoned. This level of activity will require the use of the following
response plan:
1.
2.
Isolate the area. The primary goal and responsibility is to safeguard lives.
a.
Restricting access to the affected area effectively seals off the
disturbance. The objective of isolation is to prevent the spread of
the unrest to unaffected areas, to prevent the escape of individuals
identified for arrest, and to evacuate the area of uninvolved persons
and keep others out of the area.
b.
Building clearing - Control forces may be needed to [email protected]
buildings in the affected area, checking for trapped, non-involved
persons and to identify possible hot spots or buildings requiring
special attention, such as gun shops, hardware stores, etc.
Isolation techniques
There are several techniques for isolating a disturbance area.
NOTE: Click on right arrow to reveal AIsolation [email protected]
a.
Use of barricades. The use of physical barriers would deny or limit
entry and exit from the disturbance area. Usually only effective as
long as the barricades are manned.
Basic Law Enforcement Training
Hypermedia
30
Crowd Management
L.
b.
Roadblocks. To be effective, roadblocks must not be easily
breached by vehicles. Example, 55-gallon drums filled with water
or sand, sandbags, or heavy vehicles are all effective roadblocks.
c.
Perimeter patrols that operate along the outer boundaries of the
affected area can be effective. The purpose is to prevent entry to
or exit from the area. Perimeter patrols can also help capture
identified ring leaders fleeing the area.
Techniques for Crowd Control
There are numerous techniques designed to provide agencies with flexibility of
action in accomplishing crowd control. Selection may consider a combination of
techniques which will produce the desired result within the framework of the
selected crowd control option.
The most common techniques used are:
1.
Observation - This consists of the deployment of teams to the peripheral
areas of the crowd for the purpose of monitoring activities. Teams gather
information on the crowd size, location and mood, and report on developing
situations.
2.
Communications of interest and intent - In certain situations, the effective
communication with crowd leaders and participants may enable police
personnel to control the situation without resorting to more severe action.
3.
Cooperation - Active initiation by control forces to obtain the cooperation of
group leaders may significantly decrease the potential for disruption of the
crowd activity.
Proclamation - A proclamation establishes the illegal nature of the crowd=s
action and is an excellent medium to make known to the crowd the intent of
control forces supervision. The proclamation is also a means of reducing
the size of the crowd prior to direct action being taken. In making any
proclamation to a crowd, consideration must be given to not stating a
definite time for dispersal because the situation may change and this may
not leave supervisors free to select alternate courses of action at the time of
his/her choosing.
4.
5.
Show of force - Marching a well equipped, highly disciplined control force
into view of a crowd may be all of the force necessary to persuade them to
disperse peacefully. On the other hand, in some situations, such as with
idealistically-motivated groups, a show of force may have a
counterproductive effect by causing them to become involved in a direct
challenge of control forces. Ten well trained officers can effectively
disperse 1,000 rioters.
Basic Law Enforcement Training
Hypermedia
31
Crowd Management
6.
Crowd control formation - Crowd control formations, when properly
employed and effectively executed against a crowd of a limited size
represents one of the most practical methods of crowd control and
dispersal. A supervisor must always realize the limits of crowd control
formations.
When a large crowd has been dispersed, do not assume that members of
the crowd have returned to peaceful activity; small groups may initiate
dispersed riotous activities, therefore, the use of formation should only be
part of a total dispersal effort. Also, if the crowd refuses to move, other
techniques may have to be employed, such as the use of riot control agents
and physical arrest.
7.
Arrest and processing of arrestees
a.
Arrest teams - All arrest teams will be under the direct supervision
of an arrest team supervisor. During times of civil disorder,
individual police action will be suspended and arrests will only be
made under the direction of a supervisor. Arrest team members
will escort prisoners to a central prisoner processing area.
b.
Processing of arrestees - A point outside the affected area, yet
close by, will allow for the quick return of arrest team personnel to
maximize their effectiveness.
At the arrest processing point, the arresting officer should have his
photograph taken with the prisoner for later identification and court
purposes.
c.
Special considerations of arrests
During times of civil unrest, physical arrest must be kept to a
minimum, not to appease the crowd, but to economize on the
limited number of police resources. Therefore, individual police
action must be suspended. Supervisors will determine the course
of action to include all arrests. Exception: emergency life or death
situations. Procedures must also be established to deal with
arrestees, transportation, and detainment.10

Sniper Action
Basic Law Enforcement Training
Hypermedia
36
Crowd Management
Most law enforcement agencies are not equipped to deal with large scale anti-sniper
operations. A police agency paralyzed by sniper fire cannot effectively prevent mob
violence from spreading out of control. Specialized units such as SWAT or SRT
counter sniper teams must be used to counter this threat. A skilled sniper, using
high velocity, scope-sighted firearms, can operate from a distance of 300 yards or
more. The range effectively eliminates the sound, leaving only the impact of the
round or the sound of the projectile passage to indicate an approximate position.
A well concealed sniper using a low-velocity weapon, such as .22 caliber rifle, can
fire on a target from a much closer range and still remain relatively safe from police
counteraction, especially if the area is engulfed in wild riotous confusion.
Note: It takes specially trained counter sniper actions using proven military-type
actions to eliminate this type of threat. The average street officer is not equipped to
handle this situation.
Therefore, whenever this is encountered during crowd control operations, officers
should seek cover and call for the assistance of specialized anti-sniper teams to
eliminate the threat.
NOTE: Sniper as used in this text means any hidden, armed threat. AAn

Control forces should re-enter the area only when sufficient personnel have arrived
to deal with the situation or employ more tactically advanced methods or special
purpose tactics. If unable to re-enter, isolation of the area is the best option.
R.
Mobile Tactics
Traditional crowd control tactics were developed in the 1960's to meet the threat of
civil unrest in large urban areas. This was also a time of limited mobility of the
populace, which meant officers had to keep up with the foot pace of the crowds.
In today's fast moving society, traditional slow moving, highly predictable tactics
make control force personnel vulnerable to attack and flanking movements. These
tactics also fatigue officers who must cover great distances on foot, often carrying
up to 30+ pounds of equipment, not to mention the heat retention of body armor.
The tactics can also be effectively countered by small groups and groups using
[email protected] tactics. Mobile concepts are designed to help overcome these obstacles.
This concept allows for a rapid, organized, and disciplined response in sufficient
numbers to handle most situations quickly and decisively.

NOTE: Click on right arrow to reveal AMiami [email protected]
This system is designed to provide for the rapid, organized, and
disciplined response to civil disorder and crowd confrontations.
Vehicles move field force personnel from one point to another as
rapidly as possible in a unified manner. With this model the parade
of patrol units arriving into the areas is effectively the first show of
force. This parade may encourage some participants to leave the
area, or it may enrage the crowd to act, so the officer should be
prepared to deal with either situation.

This concept allows for more flexibility and rapid movement of
personnel. Vehicles are used to not only move officers, they are
used to supplement their numbers. Commanders now have more
flexibility to cover larger areas, using fewer personnel to achieve
the maximum effect quickly. This concept is not a 90 mph
approach, rather it is a deliberate movement of patrol cars, driving
at speeds of 10 to 15 mph. These speeds give the officers the
ability to cover ground quickly, yet it allows rioters time to
disperse.

Mobile tactics are built around squad, which is the basic element of crowd
formations, traditional or mobile. Each squad is supervised and controlled
by a sergeant. Squads should have twelve (12) members, with the
sergeant, driver, and two officers in one unit; the other units have four (4)
officers each. Variations can be tailored to meet the manpower of an
individual agency or the situation; however, no fewer than two officers per
unit should be used. This approach is functional with as few as two (2)
officers per patrol unit. This forms squads of at least six (6) officers.
3.
Procedure
The squad is the smallest element that should confront a crowd. More units
or squads should be available to support the initial squad as needed. They
can also be used to secure flanks and parallel the contact squad as it moves
the crowd, thereby preventing them from being out flanked.
4.
a.
When commanded to move forward, the initial squad moves
toward the crowd with siren, emergency lights, and all other lights
on. Speed should be rapid, but slow enough so officers can
control their own responses.
b.
As the squad of vehicles approaches the crowd, the squad leader
gives out a dispersal command, such as Askirmish line, [email protected]
This is the signal for the lead unit to break to the left and stop, the
second unit pulls straight forward, with the third breaking to the
right. As the units roll to a stop, parallel to each other, the sirens
are turned off and officers quickly dismount to form a skirmish line
in front of the patrol units. If the confrontation occurs at night, the
headlight should be turned off at this point, so as not to backlight
the skirmish line. The blue lights will make the number of officers
appear to be moving or may give the illusion that there are more
officers than there are. As the officers advance, the drivers of the
patrol units move slowly forward with the skirmish line.
Leapfrog technique
NOTE: Click on right arrow to reveal ALeapfrog [email protected]
This technique is used to exploit the initiative gained by the first squad,
should the crowd retreat. This procedure requires a minimum of two
squads, with one in direct contact with the crowd and the second in
support. In order for the second squad to advance, the first squad must
create an opening. A command might be ABreak! Break! [email protected] or a
blowing of the siren or horn to signal the front quad to break open. This
maneuver requires the center of the skirmish line to move to one side, with
the center unit advancing until they can pull to one side. This opens the
way for the second squad to move forward, until they deploy. The first

squad then enters their patrol units and moves forward in a column behind
the second squad. This method can be repeated as many times as is
necessary to disperse the crowd.
5.
Pitchfork technique
NOTE: Click on right arrow to reveal APitchfork [email protected]
This technique utilizes a full field force and is designed to clear larger areas.
Two squads focus on the crowd, while two other units are positioned to
each side to flank the center squad. Coordination is a key to the success of
this technique.

Three unit rescue (L.A. Model)
NOTE: Click on right arrow to reveal AThree Patrol Car

Mobile tactics can be used for rescue of officers and citizens in
hostile encounters. This technique calls for the squad to advance
forward in a column, then forming a horseshoe or open box
formation around the victim, where officers dismount, some
picking up the victim, with others using chemical munitions or
specialty impact munitions to ward off the crowd. Once the victim
is placed in the nearest unit, officers remount and withdraw to
safety.

the contact unit. The driver and drivers side passenger cover the
flank, while the passenger side officers act as the rescuers.
Position the second unit at a 45 degree angle at the rear of the
[email protected] vehicle or scene, with officers deploying to cover the
rescue. The vehicles then back out of the area, keeping the
crowd/rioters in front of them.13

Use of Chemical Agents
The proper use of chemical agents not only helps law enforcement personnel restore
order, but reduces the chances for injury to officers and rioters. On the other hand,
Basic Law Enforcement Training
Hypermedia

Crowd Management
if used improperly or indiscriminately, chemical munitions can cause injury and
possibly death. It can also lead to complaints of excessive force. 14
REMEMBER, the use of chemical agents is considered a use of force.
1.
History
The use of chemical agents began around the year 2000 B.C., when
merchants in India carried ground black pepper in rice paper to ward off
muggers. Through the ages man has refined the use of chemical munitions
from the use of crude methods, such as the burning of pitch tar by the
Spartans to blind and choke their enemies to the chemical agents in use
today.
2.
Introduction to chemical agents
Currently there are four forms of chemical agents used by law enforcement
agencies for crowd control.
a.
HC (Hexachlorethane) - Smoke
Even though smoke is not an irritant agent per se, smoke in and of
itself is irritating to some people. Smoke is effective when used to
break up crowds that are disorderly, but not overtly violent.
Smoke can be used for the following purposes:
b.
(1)
Conceal movement
(2)
Disorient the crowd
(3)
Determine the wind direction
CN (Chloroacetophenone) - discovered in 1869 by a German
chemist
(1)
Odor: like apple blossoms
(2)
Incapacitation factor: 10 to 20 minutes. CN is a fast
acting irritant that affects the upper respiratory passages,
lacrimal glands and eyes. The agents usually begin to
work in 1 to 3 seconds; however, some people may not be
affected for up to 30 minutes.
(3)
CN is an irritant that does not affect everyone. Those on
drugs or alcohol may not be affected by this chemical
agent.
Basic Law Enforcement Training
Hypermedia
43
Crowd Management
(4)
Physiological effects: Irritating to the skin, causing a
burning and itching sensation. Flowing of tears, nose
irritation--agents especially affect moist areas of the body.
(5)
CN is a lacrimal, meaning it affects the lacrimal glands,
ducts, and sacs around the eyes and in the nasal and sinus
cavities. CS has an added irritant that affects the skin area
by causing a burning sensation.

Lacrimal [email protected]
c.
CS (Orthochlorbenzalmalononitrile)
Developed by the British in 1928 (B.B. Carson and R.W.
StroughtonBCS from first initial of each discoverer's last name).
CS came to the attention of American officials as a result of its use
by the British during civil unrest on the island of Cyprus in 1961.
(1)
Odor: peppery smell
(2)
Incapacitating time factor: produces almost immediate
effects in 5 to 10 seconds. Effects can last from 10 to 30
minutes.

(f)
Dizziness or swimming of the head
OC Products - Pepper Mace
The use of pepper as an irritant dates back to the year 2000 B.C.
OC products are currently limited to mace type dispenser systems.
Some field officers are currently carrying this type of agent
(Pepper mace and CAP-STUN). Because OC products are to be
sprayed directly into the eyes of a subject, they are currently less

Criteria for selection of riot agents
a.
Safety
Although chemical agents are non-lethal by design, the improper
use of these agents can cause serious injury or death. Safety is an
important consideration when an agent is deployed. Never fire or
throw grenades directly into a crowd. Deploy them above or at the
feet of the crowd for a blast dispersion, or near the crowd for a
continuous discharge.
Never use grenades or projectiles designed and intended for
external riot control inside confined areas. Never use excessive
quantities of chemical agents CN or CS.
Always leave an avenue of escape for the crowd.
b.
Effectiveness - agents should:
(1)
Produce rapid physiological reaction
(2)
Produce chemical effects in low concentration
(3)
Permit rapid recovery without lasting effects when
subjects are removed from the contaminated area
c.
Deliverability - agents must be deliverable in sufficient
concentration to be effective.
d.
Non-persistency - agents must be temporary in duration and should
not present major decontamination problems, such as the use of CS
burning munitions in a house or closed area. Persistency is directly
affected by the nature of the agent, the method of dissemination,
weather, and the area contaminated.
e.
Stability - agents should be stable over a wide range of
temperatures and must be compatible with selected delivery
systems.

Forms of chemical agents
(1)
Solids - granulated agents combined with pyrotechnic

(2)
Micro pulverized - agent reduces to extremely fine powder
or dust
(3)
Liquid - agent suspended in a liquid solvent
Methods of dissemination
(1)
Expulsion - the use of explosive or other force to eject
micro pulverized chemical agents
(2)
Pyrotechnic - the burning of granulated chemical agents
and a pyrotechnic mix to vaporize the agent and release it
as a submicron aerosol cloud
(3)
Fog - the use of hot gases to vaporize a liquid agent
formulation which is subsequently released as a fog cloud
(4)
Liquid - the use of an expelling force to project a liquid
chemical agent formulation to a desired target
Delivery systems
There are four systems for the delivery of chemical munitions.
Tactics dictate which system is most appropriate for a given
situation. Choosing the wrong delivery system may make the use
of chemical agents a burden rather than an asset.
(1)
Aerosol irritant projectors are one of the most widely used
means of deploying chemical agents.

Launching systems
(a)
37mm system - a low pressure launching system
used to deliver specialized long or short range
munitions
(b)
Shotgun system - uses a special adapter and blank
shell to lob the munition toward the target area
NOTE: Display 37mm gas gun, shotgun launcher and
blank shell.
6.
Grenade munitions - hand-held or launched
Grenades have a standard military mechanical fuse system, the M201A1.
The M201A1 fuse has a standard delay of 1.5 seconds (0.7 to 2.0) margin
of error.
When deploying a grenade the following procedures will be followed:
a.
Right handed
(1)
Basic Law Enforcement Training
Hypermedia
Hold grenade in the right hand with the safety lever in the
web of the hand. The safety pin should be straightened
but not removed. This is necessary to allow for the safe
removal of the safety pin before deploying the munition.
48
Crowd Management
b.
(2)
Remove the safety pin, by pulling it toward your mid
section and not away from the body. This procedure
reduces the chances that you will accidentally drop the
munition.
(3)
Once you have removed the pin, place the pin in your
pocket, in case you need to re-secure the munition, should
it not be deployed.
Left handed
Follow the same procedure as above, except that the grenade is
held inverted in the left hand, so the lever is still securely held in the
web of the hand.
Always throw grenades underhanded to reduce the chances of injury.
c.
Blast dispersion (expulsion grenade)
(1)
(2)
Basic Law Enforcement Training
Hypermedia
Explosive type
(a)
These grenades are filled with micro pulverized
agent
(b)
The body is weakened; an explosive force
ruptures the grenade ejecting the agent
Non-explosive type
(a)
Federal Labs piston driven system to eject agent.
This system also has a time delay fuse system.
(b)
Two-second delay for target deployment of 60 to
70 yards; a five-second delay for targets 120
yards away. The five-second delay is important
when the grenade is to be launched. The twosecond delay will be used when the grenade is
hand thrown.
(c)
Because the Federal Lab system does not burn, the
grenade can be hand-held and used as a hand-held
blast expulsion system.
(d)
Hand-held method of deployment
49
Crowd Management
1)
Check fuse selector position to ensure it is
set for a two-second delay.
Note: Do not position pointer system
between the 2 and 5 position. The pointer
must be on one or the other. Grenade will
not function if pointer is in off position.
2)
Grasp grenade body with either hand,
maintain pressure on the safety lever with
the thumb; point base (rifling band)
toward target.
3)
Grasp pull ring with free hand, remove
from grenade; place ring in pocket in case
it is needed to re-secure the safety lever;
grenade is now armed.
4)
Point discharge end of grenade toward the
target area, arm extended and grenade
pointed slightly upward. Fire agent over
the crowd so the agent will rain down
giving maximum effect. Do not fire
directly into rioters= faces. Agent can also
be directed towards the rioters= feet.
5)
To discharge, retain firm grip on grenade
body, remove thumb from safety lever,
allow lever to release. Grenade will
discharge 2 seconds after safety lever is
released. Agent will cover area of 15 to
20 feet in distance and 5 to 8 feet in width
at its peak.
6)
Re-securing the grenade: if it is decided
that the grenade will not be deployed, you
need to re-secure the safety lever.
Maintain thumb pressure on safety lever
and re-insert the safety pin.
Note: Always keep the discharge end of
the grenade pointed away from yourself.

51
Crowd Management
(2)
c.
Gas forms of munitions expand about 20% in 100 feet
(approximately 20-foot spread in 100 feet)
Target nature
Chemical munitions must be deployed in sufficient concentrations
to produce the desired effect. More munitions will be needed for
crowd control than will be required for a barricaded subject.
Assuming there is a normal wind of 5 to 10 mph, the output of
burning munitions will expand about 20% of the down wind
direction. Therefore, officers deploying chemical munitions should
determine a line of release to gain the maximum effect of the agent
on the crowd.
NOTE: Click on right arrow twice to reveal AIdeal Release
Patterns,@ Head Wind,@ and AFollowing [email protected]
(1)
Large groups
Officers must use sufficient agent to effectively cover the
entire crowd. Line of release and conversion line should
be far enough back from the crowd to reduce the threat of
Athrow [email protected] and maximize the coverage of the crowd
with chemical agent.
Important: an escape route for rioters must be
determined before chemical agents are deployed.
(2)
Small groups
Recent events continue to show the need to consider the
use of chemical agents to disperse small groups (usually 25
to 50 persons). However, the use of chemical munitions
should only be used when the crowd is disorderly to the
extent of throwing objects, physically attacking officers, or
there is imminent threat of either. When deploying
chemical munitions on small groups, officers should use
low volume munitions, so as not to affect uninvolved
bystanders of the neighborhood.
No legitimate police objective can be achieved by the indiscriminate spraying
of chemical agents onto a crowd. Also, care must be taken to avoid
discharging agent so that it only affects the front half of a crowd. This will
place incapacitated individuals between the crowd and the front ranks of the
police lines.

Legal concerns about chemical munitions
Chemical munitions have been generally accepted by the courts and public
as an acceptable use of force to disperse riotous crowds and avert what the
police could reasonably regard as threatened violence. 16
From 1934 to the present, only fifteen cases regarding the use of chemical
agents have reached the appellate courts in the U.S. No case has, to date,
been deliberated by a federal court. Therefore, it can be reasonably
assumed that the use of chemical munitions can be legally justified.
The only major issues considered by the courts have been the training of
officers and the method of deployment (e.g., firing the agent straight into
the faces of subjects).17

Crowd management is an experience that you may not encounter very often in your
day-to-day responsibilities. However, if a crowd is not managed properly, the
situation can escalate to violence very quickly. We must protect the public's right to
assemble and demonstrate, and we must protect individuals and property owners in
the vicinity of the demonstration. It is the goal of this lesson plan to provide
information to do both of these tasks equally well.
