Defend Self or Others
One of the two general areas in which an officer's use of force is justified
the process for evaluating the appropriateness of an officer's response to a subject's resistance.
the amount of force reasonably necessary to make an arrest.
Graham v. Connor
determined that the reasonableness of a particular use of force must be judged from the perspective of how a reasonable officer on the scene would respond, rather than from the 20/20 perspective of hindsight.
The Supreme Court has made clear
that use of force is a seizure under what Amendment?
Correctional officers must also consider that use of force may violate which Amendment with regards to cruel and unusual punishment?
Much litigation against criminal justice officers is not about the amount of force used, but what?
Whether the use of
force was permitted at all.
the verbal and/or physical yielding to an officer's authority without apparent threat of resistance or violence.
increasing the use of force or resistance
decreasing the use of force or resistance
discontinuing a command or physical use of force
provide a framework for making decisions involving the reasonable use of force
by criminal justice officers.

a subject's attacking movements toward an officer that may cause injury but are not
likely to cause death or great bodily harm to the officer or others.
Deadly force resistance
a subject's hostile, attacking movements with or without a weapon that create a
reasonable perception by the officer that the subject intends to cause and has the capability of causing death or great bodily harm to the officer or others.
Command presence and
Can often be used to defuse volatile situations without escalating to force.
Types of Physical Force
physical control, the use of nonlethal weapons, and deadly force.

is force that is likely to cause death or great bodily harm. Some examples of deadly force include use of a firearm, eye gouges, empty-hand strikes to the throat, and impact-weapon strikes to the side of
What Are the factors for deciding the Use of Deadly Force?
refers to the subject having the means to carry out his or her intent to cause death or great bodily harm.
means the subject is capable of acting on a plan to cause death or great bodily harm to the officer or others.

Totality of circumstances
a term the court uses to refer to all facts and circumstances known to the officer at the time, or reasonably perceived by the officer as the basis for, a use of force decision.
What are the two things that the court looks at to determine Totality of Circumstances?
Was the decision objectively reasonable.
Was the decision legally justified.
Situational Factors for Totality of Circumstances
• severity of the crime
• subject is an immediate threat
• subject's mental or psychiatric history, if known to the officer
• subject's violent history, if known to the officer
• subject's combative skills
• subject's access to weapons
• innocent bystanders who could be harmed
• number of subjects versus number of officers
• duration of confrontation
• subject's size, age, weight, and physical condition
• officer's size, age, weight, physical condition, and defensive tactics expertise
• environmental factors, such as physical terrain, weather conditions, etc.
A measure of anxiety caused by an appraisal of a stimulus that leads to an extreme state
The officer's evaluation and assignment of challenge or threat value to a stimulus.
the officer's elevated mind-body state that occurs in the presence of a perceived challenge or threat.
What are the four instinctual reactions to survival stress:
fight, flight, posture, and submit.
To completely relinquish control to another.
Psychological Changes Under Stress
•Activation of Limbic System(part of brain controlling emotion & motivation)
•Activation of Fight or Flight Response by the Sympathetic Nervous System
•Domination of the Parasympathetic Nervous System by the Sympathetic Nervous System for SELF PROTECTION
(the parts of the brain that are especially focused on emotion and motivation) that
provides a survival response to the central nervous system.
Sympathetic Nervous System
the part of the autonomic nervous system that is concerned especially with preparing the body to react to situations of stress or emergency. This system activates what is often called the fight or flight response.
Parasympathetic Nervous System
sometimes called the rest and digest system, is the part of the autonomic
nervous system that is concerned with controlling the body during normal, routine situations. Can be dominated by the Sympathetic Nervous System for SELF PROTECTION
Physiological Changes Under Stress
• Increase in heart rate and respiration.
• Auditory Distortion
• Visual Distortion
• Loss of bladder and bowel control
• Increased Reaction Time
Blood flows into the larger muscle groups providing oxygen to power flight and aid
Blood flow is restricted from the extremities and skin. The body pulls the blood away from the arms and legs into the torso. This keeps the blood near vital organs in case of emergency and
also protects the arms and legs (our weapons) from losing blood in case of injury.
Hearing may be diminished or amplified.
Officers may as see darkness around the edges of their vision (tunnel vision). Officers may also lose the ability to see
close objects with detail (farsightedness).
the tendency of your eyes to fixate to one location.
Fine motor skills
refer to the muscle control required to make small, precise movements, such as unlocking handcuffs with a key.
Gross motor skills
the movements of the large or major muscles of the body, which are used in tasks such as running, punching, or kicking.
Complex motor skills
combine fine and gross motor skills using hand and eye coordination timed to a single event, such as driving a vehicle.
Perceptual Time Distortion
Occurrences seem to be faster or slower than they actually are.
Perceptual Space Distortion
Objects appear to be closer or farther than they actually are.
• mental shortcuts that allow people to solve problems and make judgments quickly and efficiently.
• based on past training and experience.
officers who are in a state of high arousal later regret or do not recall the things they have said during this period of anxiousness
• Unaware that a threat exists
• Attention is unfocused or preoccupied, and the officer is oblivious to potential danger in his or her environment.
• Example: A person drives to work and does not remember the drive (automatic pilot).
Desired State for Officers
• General awareness of possible threats
• Attention is focused, and the officer scans the environment for potential threats.
• Example: While on the job, an officer is in a state of relaxed awareness and notices what is going on around him or her.
• Recognition that a threat exists
• Awareness of a specific
threat encourages pre-planning and more intense focus. Physical indicators of stress may become evident.
• Example: A correctional officer observes an inmate with possible contraband and begins formulating a plan of action.
• Specific threat identified and appropriate actions taken
• The threat is assessed and managed through intensified cognitive and physical reactions. Survival stress functions become optimum.
• Example: The correctional officer initiates the plan to engage the inmate.
• Threat mismanaged due to panicked stress response
• Survival stress functions break down. Submission or freezing may occur.
• Example: The correctional officer panics and may not respond effectively.
critical incident amnesia
a temporary or sometimes permanent condition where officers experience short and long-term memory loss.
• During: diminished ability to process other information.
• After: inability to remember information observed during the incident.
• vulnerable to false memories and unintentional fabrications that they use to link flash memories of the critical incident.
Coping with the Effects of Survival Stress
• stay physically fit
• get adequate rest
• eat a nutritious diet
• use controlled breathing techniques
• rely on techniques that involve gross motor movements rather than fine motor skills
• train under realistic environmental conditions designed to mirror high-stress
• anticipate the possibility of resistance with every subject encounter
• maintain proficiency in physical and mental skills
• maintain proficiency with firearms and other issued equipment
