A use of force continuum is a standard that provides law enforcement officers and civilians with guidelines as to how much force may be used against a resisting or compliant subject in a given situation. In some ways, it is similar to the U.S. military's escalation of force (EOF). The purpose of these models is to clarify, both for law enforcement officers and civilians, the complex subject of use of force. They are often central parts of law enforcement agencies' use of force policies. Various criminal justice agencies have developed different models of the continuum, and there is no universal or standard model. [1] Generally, each different agency will have their own use of force policy. Some agencies may separate some of the hand-to-hand based use of force. For example, take-downs and pressure point techniques may be one step before actual strikes and kicks. Also, for some agencies the use of aerosol pepper spray and electronic control devices (TASER) may fall into the same category as take-downs, or the actual strikes.
The first examples of a use of force continuum were developed in the 1980s and early 1990s. [2] Early models were depicted in various formats, including graphs, semicircular "gauges", and linear progressions. Most often the models are presented in "stair step" fashion, with each level of force matched by a corresponding level of subject resistance, although it is generally noted that an officer need not progress through each level before reaching the final level of force. These progressions rest on the premise that officers should escalate and de-escalate their level of force in response to the subject's actions. [3]
Although the use of force continuum is used primarily as a training tool for law enforcement officers, it is also valuable with civilians, such as in criminal trials or hearings by police review boards. In particular, a graphical representation of a use of force continuum is useful to a jury when deciding whether an officer's use of force was reasonable. [4]
While the specific progression of force varies considerably (especially the wide gap between empty hand control and deadly force) among different agencies and jurisdictions, one example of a general use of force continuum model cited in a U.S. government publication on use of force is shown below. [5]
The U.S. Navy teaches a six-step model: Officer presence, Verbal commands, Soft controls, Hard controls, Intermediate Weapons, and Lethal force. Hard controls includes the use of tools such as hand-cuffs, while soft controls equates to empty hand above, describing techniques where the officer may engage a resisting detainee. When escalating, voluntary submission to cuffs is a viable way to prevent the need for empty hand submission techniques which place the officer and the detainee at physical risk. When de-escalating, hard controls (i.e.: cuffs and isolation in the rear seat of a cruiser) give officers a reasonable and achievable goal after altercation with a detainee during which higher levels of force may have been required. [9] [13] [14]
In all use of force continuum models, the actions of the subject is classified in order for the officer to quickly determine what level of force is authorized and may be necessary to apprehend or compel compliance from the individual. Listed below are examples of how subjects are classified.
Generally, the passive subjects and active resistors fall under levels 1–3 of the use of force continuum, while active aggressors fall under levels 4–6. The officers are trained to apply the proper measure of force within the continuum based on the actions and classification of the subject. [15]
The United States Supreme Court, in the case of Graham v. Connor , (1989) ruled that excessive use of force claims must be evaluated under the "objectively reasonable" standard of the Fourth Amendment. Therefore, the "reasonableness" factor of a use of force incident must be judged from the perspective of a reasonable officer on the scene, and judged with the understanding that police officers are often forced to make split-second decisions about the amount of force necessary in a particular situation.
Broadly speaking, the use of force by an officer becomes necessary and is permitted under specific circumstances, such as in self-defense or in defense of another individual or group. However, there is no all encompassing consensus about when an officer would always need to use force, nor is there any agreed upon method that can efficiently measure or predict specific types of force actions that one would deem reasonable before the time comes.
The International Association of Chiefs of Police, has described use of force as the "amount of effort required by police to compel compliance by an unwilling subject". [17]
Garner and Maxwell (1996) [18] found that when force was necessary, in 80 percent of the encounters, police opted to use weaponless force such as grabbing or shoving. Alpert and Dunham (1999) [19] show that police use of force is reactionary, initiated by suspect resisting arrest. Force is more likely to be employed if suspect is disrespectful, intoxicated, and/or wielding a weapon. Research has also found that special division officers are more likely to use deadly force on suspects. [20]
Studies examining gender influences on the use of force are still inconclusive. Some findings suggest that male suspects are more likely to have force used against them, whereas others show insignificant differences. However, research examining male-female patrol teams show that these pairings are less likely to use force compared to male-male pairings. Conclusions suggest that female officers may be more effective at diffusing tense situations. [21]
Deadly force, also known as lethal force, is the use of force that is likely to cause serious bodily injury or death to another person. In most jurisdictions, the use of deadly force is justified only under conditions of extreme necessity as a last resort, when all lesser means have failed or cannot reasonably be employed.
Non-lethal weapons, also called nonlethal weapons, less-lethal weapons, less-than-lethal weapons, non-deadly weapons, compliance weapons, or pain-inducing weapons are weapons intended to be less likely to kill a living target than conventional weapons such as knives and firearms with live ammunition. It is often understood that unintended or incidental casualties are risked wherever force is applied; however, non-lethal weapons minimise the risk of casualties as much as possible. Non-lethal weapons are used in policing and combat situations to limit the escalation of conflict where employment of lethal force is prohibited or undesirable, where rules of engagement require minimum casualties, or where policy restricts the use of conventional force. However, these weapons occasionally cause serious injuries or death due to allergic reactions, improper use and/or other factors; for this reason the term "less-lethal" has been preferred by some organizations as it describes the risks of death more accurately than the term "non-lethal", which some have argued is a misnomer.
Pepper spray, oleoresin capsicum spray, OC spray, capsaicin spray, or capsicum spray is a lachrymator product containing the compound capsaicin as the active ingredient that irritates the eyes to cause burning and pain sensations, as well as temporary blindness. Its inflammatory effects cause the eyes to close, temporarily taking away vision. This temporary blindness allows officers to more easily restrain subjects and permits people in danger to use pepper spray in self-defense for an opportunity to escape. It also causes temporary discomfort and burning of the lungs which causes shortness of breath. Pepper spray is used as a less lethal weapon in policing, riot control, crowd control, and self-defense, including defense against dogs and bears.
A TASER is a conducted energy device (CED) primarily used to incapacitate people, allowing them to be approached and handled in an unresisting and thus less-lethal manner. The brand name product is sold by Axon, formerly TASER International, the TASER fires two small barbed darts intended to puncture the skin and remain attached to the target until removed by the user of the TASER device. The deployment of a taser typically reaches a speed of 55 m/s and a range extending from 4.5 m (15 ft) for non-Law Enforcement Tasers to 10.5 m (34 ft) for Law Enforcement Tasers. The darts are connected to the main unit by thin wires that achieve a high dielectric strength and durability given the extreme high-voltage,. The wire core often being copper wire modulates electric current designed to disrupt voluntary control of muscles, causing "neuromuscular incapacitation (NMI)". When successfully used, the target is said to have been "tased". The effects of a taser may only be localized pain or strong involuntary long muscle contractions, based on the mode of use and connectivity of the darts.
Riot control measures are used by law enforcement, military, paramilitary or security forces to control, disperse, and arrest people who are involved in a riot, unlawful demonstration or unlawful protest.
An electroshock weapon is an incapacitating weapon. It delivers an electric shock aimed at temporarily disrupting muscle functions and/or inflicting pain, usually without causing significant injury.
The use of force, in the context of law enforcement, may be defined as, "the amount of effort required by police to compel compliance by an unwilling subject." Multiple definitions exist according to context and purpose. In practical terms, use of force amounts to any combination of threatened or actual force used for a lawful purpose, e.g. to effect arrest; defend oneself or another person; or to interrupt a crime in progress or prevent an imminent crime. Depending on the jurisdiction, legal rights of this nature might be recognized to varying degrees for both police officers and non-sworn individuals; and may be accessible regardless of citizenship. Canada's Criminal Code, for example, provides in section 494 for arrest in certain circumstances by "any one."
A Terry stop in the United States allows the police to briefly detain a person based on reasonable suspicion of involvement in criminal activity. Reasonable suspicion is a lower standard than probable cause which is needed for arrest. When police stop and search a pedestrian, this is commonly known as a stop and frisk. When police stop an automobile, this is known as a traffic stop. If the police stop a motor vehicle on minor infringements in order to investigate other suspected criminal activity, this is known as a pretextual stop. Additional rules apply to stops that occur on a bus.
Conflict escalation is the process by which conflicts grow in severity or scale over time. That may refer to conflicts between individuals or groups in interpersonal relationships, or it may refer to the escalation of hostilities in a political or military context. In systems theory, the process of conflict escalation is modeled by positive feedback. Conflict escalation can be modeled with game theory. In contrast, de-escalation are approaches which lead to a decrease or end of a conflict.
A pepper-spray projectile, also called a pepper-spray ball, pepper-ball, pepper bomb, or pepper-spray pellet, is a frangible projectile containing a powdered chemical that irritates the eyes and nose in a manner similar to pepper spray. These projectiles are fired from specially designed forced compliance weapons or modified paintball guns.
In military and police contexts, a warning shot is an intentionally harmless artillery shot or gunshot with intent to enact direct compliance and order to a hostile perpetrator or enemy forces. It is recognized as signalling intended confrontations on land, sea, and air.
Pain compliance is the use of painful stimulus to control or direct an organism.
Tennessee v. Garner, 471 U.S. 1 (1985), is a civil case in which the Supreme Court of the United States held that, under the Fourth Amendment, when a law enforcement officer is pursuing a fleeing suspect, the officer may not use deadly force to prevent escape unless "the officer has probable cause to believe that the suspect poses a significant threat of death or serious physical injury to the officer or others."
As of 2024, more than 1,280,000 sworn law enforcement officers are serving in the United States. About 137,000 of those officers work for federal law enforcement agencies.
A correctional emergency response team is a team of specially trained prison officers tasked with responding to disturbances, riots, cell extractions, mass searches, and other situations in prisons that are likely to involve uncooperative or violent prisoners.
A baton is a roughly cylindrical club made of wood, rubber, plastic, or metal. It is carried as a compliance tool and defensive weapon by law-enforcement officers, correctional staff, security guards and military personnel. The name baton comes from the French bâton (stick), derived from Old French Baston, from Latin bastum.
Police accountability involves holding both individual police officers, as well as law enforcement agencies responsible for effectively delivering basic services of crime control and maintaining order, while treating individuals fairly and within the bounds of law. Police are expected to uphold laws, regarding due process, search and seizure, arrests, discrimination, as well as other laws relating to equal employment, sexual harassment, etc. Holding police accountable is important for maintaining the public's "faith in the system". Research has shown that the public prefers independent review of complaints against law enforcement, rather than relying on police departments to conduct internal investigations. Public perception of police accountability can be partisan. Electoral accountability can improve police accountability of asset forfeiture.
The Bakersfield Police Department (BPD) is the agency responsible for law enforcement within the city of Bakersfield, California, in the United States. It has over 590 officers and professional staff, covering an area of 151.2 square miles (392 km2) serving an urban population of more than 400,000. The current chief of the department, since April 2020, is Greg Terry. The department protects the city, split between two areas and six zones with two stations, the main department headquarters and the west side substation. The department administration is made up of the chief of department, two assistant chiefs, four captains and eleven lieutenants.
Use-of-force law in Missouri refers to the law & legal doctrine which determine whether a member of law enforcement in the state of Missouri is justified in the amount of force used to gain control of an unruly situation or person, including situations involving death. In the United States, doctrine about use of force is primarily defined by the individual states, although there have been some Supreme Court decisions of limited scope.
In the United States, use of deadly force by police has been a high-profile and contentious issue. In 2022, 1,096 people were killed by police shootings according to The Washington Post, while according to the "Mapping Police Violence" (MPV) project, 1,176 people were killed by police in total. MPV documented 1,213 killings by police for 2023.
