Definition
The unintentional firing of a conducted energy device (CED).
Depressing the trigger of a CED causing a CED to arc or to fire probes.
A threat or overt act of an assault (through physical or verbal means), coupled with the present
ability to carry out the threat or assault, which reasonably indicates that an assault or injury to
any person is imminent.
Physically evasive movements to defeat an officer’s attempt at control, including bracing,
tensing, pushing, or verbally signaling an intention to avoid or prevent being taken into or
retained in custody.
Deadly force encounter.
A replaceable cartridge which uses compressed gases to fire two probes on connecting wires
sending a high voltage/low current signal into a subject.
Response determined appropriate for the given operational scenario.
Activating a CED with no cartridge.
An apparatus that monitors the heart of the patient and then automatically administers a
controlled electric shock to the chest to restore normal heart rhythm.
Generic responses that describe how people routinely behave as the result of
the application of a weapon or technology [or tactic, or procedure] employed against them.
Injury to the human body that requires treatment by a doctor or other health professional.
Duration of a CED electrical discharge following a CED activation.
Display of data on the back of a conducted energy device.

A circular force training model that promotes continuous critical assessment and evaluation of a
force incident in which the level of response is based upon the situation encountered and level
of resistance offered by a subject. The situational assessment helps officers determine the
appropriate force option, ranging from physical presence to deadly force.
Injuries received in the incident not directly related to CED use (such as baton use, self-inflicted
wounds, gunshot wounds).
A weapon primarily designed to disrupt a subject’s central nervous system by means of
deploying electrical energy sufficient to cause uncontrolled muscle contractions and override an
individual’s voluntary motor responses.
Confetti-like tags expelled from a cartridge of a CED when fired to shoot probes. Each tag
contains a serial number unique to the specific cartridge used.
A training model/philosophy that supports the progressive and reasonable escalation and deescalation of officer-applied force in proportional response to the actions and level of resistance
offered by a subject. The level of response is based upon the situation encountered at the scene
and the actions of the subject in response to the officer’s commands. Such response may
progress from the officer’s physical presence at the scene to the application of deadly force.
The use of police action to stop the activities of persons assembled.
Observing, monitoring, and facilitating the activities of persons assembled.
Projectiles that are fired from a CED and penetrate the skin; wires are attached to the probes
leading back to the CED.
Point of entry for a probe on a person’s body.
The act of removing a probe from a person’s body or clothing.
Physical actions that attempt to prevent officer’s control including flight or attempt to flee, but
do not involve attempts to harm the officer.
Sending CED devices into the field with law enforcement officers.
Any tactic or use of force that has an intended, natural, and probable consequence of serious
physical injury or death.
Barbs fired at a subject.
To stun a subject with a CED by making direct contact with the body after a CED cartridge has
been expended or removed for pain compliance.
The aggregate period of time that CED shocks are activated.

The machine that measures and records the electrical activity of the heart.
Effect CED has on the body. Overrides the brain’s communication with the body and prevents
the voluntary control over the muscles.
Factors such as wind speed, temperature, humidity, lighting, precipitation, terrain, etc.
The application of an unreasonable amount (or force too long applied) of force in a given
incident based on the totality of the circumstances.
State of extreme mental and physiological excitement, characterized by extreme agitation,
hyperthermia, epiphoria, hostility, exceptional strength, and endurance without fatigue.
Circumstances that would cause a reasonable person to believe that prompt action is necessary
to prevent physical harm to civilians and/or officers.
Discharging CED darts at a person.
An active attempt by a person to avoid apprehension by a law enforcement officer through
evasive actions while attempting to leave the scene.
The ability to disrupt or control a group of individuals by either restricting or enhancing their
organization, cooperation, and density.
The first basic CED training provided to officers prior to issuance of a CED.
An investigation of the circumstances surrounding the firing or drive-stunning of a CED.
A weapon usage category situated between a verbal command and lethal force on a traditional
force continuum.
Unholstering and pointing a CED at a person and activating the device’s laser dot.
A concept of planning and force application that meets an operational or tactical objective, with
less potential for causing death or serious injury than conventional more-lethal police tactics.
Any apprehension or restraint device that, when used as designed and intended, has less
potential for causing death or serious injury than conventional police lethal weapons.
Measures indicating the degree to which a target response satisfies a requirement within an
operational context.
Measures indicating how a target reacts to a system’s effects.
Reasonableness of a particular use of force must be judged from the perspective of a reasonable
