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.
In the United States, a SWAT team is a generic term for a police tactical unit.
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, but non-lethal weapons try to 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.
In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy/hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy/hostile targets, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire, and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting.
Close-quarters combat (CQC) or close-quarters battle (CQB) is a close combat situation between multiple combatants involving ranged or melee combat. It can occur between military units, law enforcement and criminal elements, and in other similar situations. CQB is typically defined as a short duration, high intensity conflict characterized by sudden violence at close range.
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.
The Emergency Response Team are police tactical units of the Royal Canadian Mounted Police based throughout Canada and are mainly part-time teams. According to the RCMP, the ERT "is a group of highly-trained RCMP members capable of employing specialized weapons, equipment, and tactics to resolve extremely high-risk situations." The ERT is also mandated to assess the situation and determine whether extreme danger or the presence of small arms cannot be easily resolved by RCMP officers on general duties or by other police forces throughout Canada. The ERT offers consulting services to its fellow officers such as firearms files and shootings that involve police officers.
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".
Operation Kratos was a set of tactics developed by London's Metropolitan Police Service for dealing with suspected suicide bombers, most notably firing shots to the head without warning. The tactics were developed shortly after the 11 September 2001 attacks, based in part on consultation with Israeli and Sri Lankan law enforcement agencies on how to deal with suicide bombers. Little was revealed about these tactics until after the mistaken shooting of Jean Charles de Menezes on 22 July 2005, in the wake of the 7 July 2005 London bombings. The term is no longer used by the Metropolitan Police, although similar tactics remain in force.
A firearms unit is an armed unit within each territorial police force in the United Kingdom. For the most part, the police forces of the United Kingdom are unarmed; however, all have firearms units to provide the police force with the capability to deal with terrorists and armed criminals. A police officer cannot apply to join the firearms unit without first finishing their two-year probationary period, with a further two years in a core policing role for some forces. Firearms unit is the most common name outside of the capital, while that of London's Metropolitan Police Service is called the Specialist Firearms Command, Trojan or SC&O19. Within the media it is sometimes compared to the SWAT units of the United States.
The Special Task Force (STF) is the elite police tactical unit of the South African Police Service (SAPS). The Special Task Force handles high risk operations that fall beyond the scope of classic policing which require specialised skills.
Self-defence is a defence permitting reasonable force to be used to defend one's self or another. This defence arises both from common law and the Criminal Law Act 1967. Self-defence is a justification defence rather than an excuse.
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 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. 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.
Metropolitan Division, commonly referred to as Metro Division or just Metro, is an elite division of the Los Angeles Police Department (LAPD) under its Special Operations Group. Metropolitan Division is responsible for managing the LAPD's specialized crime suppression, K-9, mounted, and SWAT units, named "platoons".
Shooting to wound refers to attempts to use a firearm to harm someone without killing them. It is controversial since the unpredictable nature of firearm wounds could result in the wound failing to incapacitate the target; it may accidentally kill or miss the target, the latter presents a risk of unintended casualties. Limbs are one main area often targeted when shooting to wound. However, limbs are smaller and can be moved faster and more radically than the torso, so the option of shooting to wound is generally viewed with skepticism by law enforcement in the United States.
The use of firearms by police forces varies widely across the world, in part due to differences in gun use policy, civilian firearm laws, and recording of police activity. Police forces may require that officers use warning shots before aiming on-target, officers may need to make verbal warnings before using their firearms, and officers may be prohibited from carrying weapons while performing tasks such as highway patrol where gun use is not expected.
On July 11, 2016, Randy Lozoya and John Tennis, two Sacramento police officers, attempted to run over, and later shot and killed Joseph Mann, a 51-year-old mentally ill and homeless African-American man armed with a knife.
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.
The 1991 New Zealand bravery awards were announced via a Special Honours List dated 19 December 1991. Twelve of the 33 recipients were recognised for acts of bravery during the Aramoana Massacre on 13 November 1990.
Plumhoff v. Rickard, 572 U.S. 765 (2014), is a United States Supreme Court case involving the use of force by police officers during high-speed car chases. After first holding that it had jurisdiction to hear the case, the Court held that the conduct of the police officers involved in the case did not violate the Fourth Amendment to the U.S. Constitution, which prohibits unreasonable searches and seizures.
