(1) When the officer reasonably believes it necessary to defend himself/herself or another from bodily harm while making an arrest. (2) When necessary to apprehend an escaped felon. (3) When necessary to arrest felons fleeing from justice. The officer must have reasonably believed the fleeing felon posed a threat of death or serious physical harm to the officer or others; or the officer reasonably believed the fleeing felon had committed a crime involved the infliction or threatened infliction of serious physical harm to another person.
Who does F.S. 944 apply to?
This statute specifically addresses the use of force by state correctional and correctionl probation officers.
What does F.S. 945 establish?
It establishes that the Department of Corrections has jursidiction over the supervisory and protective care, custody, and control of inmates and offenders.
How does F.S. 944 impact the use of force applied to inmates by corrections officers?
The use of physical force is only authorized if...(1) Needed to defend himself/herself or another against an imminent use of unlawful force. (2) To prevent an escape of someone lawfully detained. (3) Prevent damage to property. (4) Quell a disturbance. (5) Overcome physical resistance to a lawful command. (6) To administer medical care that is deemed necessary for health of inmate or others.
How do you define the term objective reasonableness?
This is used to evaluate the appropriateness of an officer's response to a subject's resistance. 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. Courts look at the facts and circumstances known to the officer when the incident occurred.
What is needed for an officer to have the authority to use force?
A law enforcement officer's authority to use force is established by the officer's reasonable belief that a crime has been, is being, or is about to be committed. Absent this belief, known as reasonable suspicion, a police officer has no authority over a subject, and thus no permission to use any amout of force at all.
Define compliance.
Is the verbal and/or physical yielding to an officer's authority without apparent threat of resistance or violence.
Define escalation.
Is the increasing use of force or resistance.
Define de-escelation.
Is the decreasing use of force or resistance.
Define disengagement.
Is discontinuing a command or physical use of force, for example by breaking away from a subject.
How does the injury potential to an officer affect his/her response?
Officers are legally permitted to escalate their use of force as the subject escalates his or her level of resistance. The officer's choices are determiend by the subject's actions and the risk of physical harm posed to the officer or others.
What is the purpose of Force Guidelines?
They provide a framework for making decisions involving the reasonable use of force by police officers. The Force Guidelines are derived from constitutional considerations and case law and describes appropriate decision making in a fluid and dynamic situation.
What is passive resistance?
Is a subject's verbal and/or physical refusal to comply with an officer's lawful direction causing the officer to use physical techniques to establish control.
What is active resistance?
Is a subject's use of physically evasive movements directed toward the officer such as bracing, tensing, pushing, or pulling to prevent the officer from establishing control over the subject.
What is agressive resistance?
Is 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.
What is deadly force resistance?
Is 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.

What must an officer based their decision on when using deadly force?
Must base it on a clear, reasonable belief that he or she, a fellow officer, or another person, faces imminent danger of death or great bodily harm.
What three criteria do officer's use for making deadly force decisions?
Ability (subject having the means to carry out his/her intent to cause death or great bodily harm), opportunity (Subject is actually capable of carrying out an intention to cause death or great bodily harm...a subject wielding a knife far away may not be an immediate threat to an officer) , and intent (A reasonably perceived imminent threat to an officer or another person based on the subject's actions, behaviors, words, or other indicators. A perception derived from the totality of the circumstances.)
How does the court utilize the "totality of the circumstances" when evaluating a use of force decision by an officer?
Totality of the circumstances refers to all facts and circumstances known to an officer at the time or reasonably perceived by the officer. This includes consideation of the subject's form of resistance, all reasonably perceived factors that may have an effect on the situation, and the response options available to an officer.
What situational factors does the court consider when evaluating an officer's use of force decision?
Severity of crime; Was subject an immediate threat; Subject's mental or psychiatric history if known to officer; Subjects violent history if known to officer; Subject's combative skills; Subject's access to weapons; Potential of innocent bystanders to be harmed; Number of subjects versus number of officers; Duration of the confrontation; Subject's and officer's size, weight, age, and physical condition; Environmental factors such as type of terrain or weather.
What is survival stress?
Is stress caused by hormonal changes brought on by a perception of danger. The hormones cause an elevated heart rate that affects an officer's cognitive decision making skills.
What is posturing?
Acting like you are going to resist through verbal or physical cues. Acting like a "Peacock".
What physiological changes occur when experiencing survival stress?
The heart rate and respiration increase. Vascular flow moves away from the extremeties. The body pulls the blood way 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 from losing too much blood in case of injury. Hearing also becomes diminished.
Define auditory exclusion.
Your hearing becomes diminished when you experience survival stress.
What motor performance changes take place when experiencing survival stress?
There is a loss of fine motor skills at a heart rate of approximately 115 beats per minute. There is a loss of complex motor skills at a heart rate of 145 beats per minute. Gross motor skills are enhanced as the heart rate reaches 150 beats per minute. Catastrophic motor skill breakdown occurs when the heart rate exceeds 175 beats per minute.
Define fine motor skills.
This refers to the muscle control required to make small, precise movements, such as unlocking handcuffs with a key.
Define complex motor skills.

Are the movements of the large or major muscles of the body such as running, punching, or kicking.
What is binocular vision?
A survival stress reaction in which both eyes remain open and it is very difficult to close just one eye.
What visual changes occur while experiencing survival stress?
Binocular vision (both eyes remain open) may occur. There is a loss of peripheral vision and depth perception (tunnel vision). There is a loss of near vision (becomes nearly impossible to focus).
What cognitive function changes occur while experiencing survival stress?
The cognitive brain, the part that logically thinks and plans, begins to shut down at 145 beats per minute. Decision making is inhibited. The more choices you have, the slower you are to make a decision. Reaction time increases.
Define cognitive brain.
Is the part of the brain that logically thinks and plans.

Define joint manipulation.
Gaining control by bending or twisting a joint in a direction that will cause pain or discomfort to the joint.
Define motor dysfunction.
Gaining compliance by using an incapacitation technique that causes temporary impairment of muscular control.
What is fluid shock principle?
Occurs when the striking object stays on or indented in the target for an instant allowing for a full transfer of kinetic energy. This type of strike displaces the water content in the muscle and penetrates the nerves within, creating a shock wave. The effect on the subject is therefore greatly multiplied.
Why is it important for an officer to conduct a theat assessment?
An officer's assessment of a perceived threat is critical for safety and influences his or her actions when dealing with a situation. The more information an officer has, the better prepared he or she will be to assess the situation. All factors, whether obvious or not, should be considered when assessing threats.

What are the two main components of pressure point techniques?
(1) Touch pressure-touching the location of a nerve or sensitive area and applying continual, uninterrupted pressure with the tip of the finger or thumb until the subject complies. (2) Stabilization-Immobilizing the subject's head so the subject can't move or escap.
How should an officer properly utilize a pressure point technique?
As soon as the subject complies by obeying your commands release pressure to stop the pain. Applying pressure longer than 3-5 seconds may result in an adreline surge or other survival stress response.

What are the two types of chemical agents used by police?
Oleo-resin capsicum (OC) and orthochlorobenzal-malononitrile (CS). OC is preferred by police.
Define pepper spray.
OC, commonly called pepper spray, is an inflammatory agent that causes tearing and involuntary closing of the eyes, nasal discharge, sneezing, disorientation, and a sensation of respiratory distress. The skin will turn red to the inflammation and show mild signs of puffiness. Effects generally wear off in 20-40 minutes.
What is the active ingredient in oleo capsicum?
Oleo-resin capsicum is a natural derivative of cayenne pepper. The active ingredient in OC is known as capsaicin which produces the heat felt when it makes contact with human tissue.
Define Scoville Heat Units.
The heat value of capsicum is measured in Scoville Heat Units (SHU).
What are some of the physical effects of using a chemical agent on a subject?
When OC enters the eyes it causes them to involuntarily close. The subject will feel an intense burning sensation adn the capillaries of the eyes will dilate, causing the eyes to appear bloodshot. If inhaled will cause coughing and gasping. May cause gagging and even vomiting. The nasal cavity will also swell causing significant discharge of mucus and sneezing.
What steps should be taken if subject has severe reaction to chemical agent used?
Immediately seek medical attention. Stabilize the subject, maintain an open airway, and assure continous breathing and proper circulation.
What are the proper decontamination procedures to be followed?
Whenever a subject is contaminated the officer should follow the decontamination procedures as prescribed by agency policy. This should take place as soons as subject is under control. Officer should not leave a contaminated person unattended while effects are still evident.
What is strobing?
Is the act of forcefully blinking the eyes using all the muscles in the face, including those in the forehead. This blinking helps clear the vision and activates the tear ducts. Never wipe or rub eyes with fingers.
How does breathing help in the process of physical decontamination?
A rythmic inhale through the mouth and then a forceful exhale through the nose will cause the mucuous glands to begin working and the nose to run. This will clear the nasal passages and sinuses of mucus containing contaminated particles.
Are there any absolute antidotes for chemical agents used by police?
No, but decontamination solutions such as baby shampoo may decrease the effects.
What are some keys to effectively disarming a subject of his handgun?
Surprise; Don't telegraph your intentions; Action is faster than reaction; Use of verbal distraction; and Physical proximity. Your primary objective is to get the muzzle pointed in a different direction than toward you.
What are some examples of empty handed techniques that would be considered the use of deadly force?
Thumb strike to the throat or eyes; Elbow strike to temple, side of jaw, bridge of nose, back of head, throat; Eye gouge.
