Use of force
|“||Police use physical force to the extent necessary to secure observance of the law or to restore order only when the exercise of persuasion, advice and warning is found to be insufficient.||”|
Although there is no universally agreed upon single definition of use of force the International Association of Chiefs of Police defines the use of force as the "amount of effort required by police to compel compliance by an unwilling subject".
Use of force doctrines can be employed by law enforcement personnel and military personnel on guard duty. The aim of such doctrines is to balance the needs of security with ethical concerns for the rights and well-being of intruders or suspects. Injuries to civilians tend to focus attention on self-defense as a justification and, in the event of death, the notion of justifiable homicide.
U.S. military personnel on guard duty are given a "use of force briefing" by the sergeant of the guard before being assigned to their post.
For the English law on the use of force in crime prevention, see Self-defence in English law. The Australian position on the use of troops for civil policing is set out by Michael Hood in Calling Out the Troops: Disturbing Trends and Unanswered Questions; compare "Use of Deadly Force by the South African Police Services Re-visited" by Malebo Keebine-Sibanda and Omphemetse Sibanda.

Use of force continuum
The use of force may be standardized by a use of force continuum, which presents guidelines as to the degree of force appropriate in a given situation. One source identifies five very generalized steps, increasing from least use of force to greatest. It is only one side of the model, as it does not give the levels of subject resistance that merit the corresponding increases in force. Each successive level of force is meant to describe an escalating series of actions an officer may take to resolve a situation, and the level of force used rises only when a lower level of force would be ineffective in dealing with the situation. Typically any style of a use of force continuum will start with officer presence, and end with the use of deadly force.
- Presence (using the effect of the presence of an authority figure on a subject)
- Verbalization (commanding a subject)
- Empty hand control (using empty hands to search, relieve weapons, immobilize, or otherwise control a subject)
- Intermediate weapons (using non-lethal chemical, electronic or impact weapons on a subject)
- Deadly Force (using any force likely to cause permanent injury or death to a subject)
Use of force continuums can be further broken down.
U.S. Case Law
Graham Vs. Connor (1989)
On November 12, 1984 Graham, who was a diabetic, felt an insulin rush coming on and rushed to the store with a friend to get some orange juice. When the store was too crowded, he and his friend proceeded to go to another friend's house. In the midst of all this, he was being watched by a Charlotte, North Carolina police officer. While on their way to the friend's house, they were both stopped, and the tension began. Law enforcement used excessive force while making this arrest based on suspicion of robbery. After his arrest, it was concluded that Graham had a broken foot, cuts on his wrists, a bruised forehead and an injured shoulder.
Tennessee Vs. Garner (1974)
On October 3, 1974, members of the Memphis Police Department were called to respond to a possibly burglary. The police officers who arrived on scene were Elton Hymom and Leslie Wright. When they arrived to the scene, a lady standing on the porch began to tell them that she heard a noise sounding like a house was being broken into. Officer Hymon went to check, where he then saw a fleeing suspect, Edward Garner. He then realized that Garner had no weapon. Garner began an attempt to flee away from the house and as he was climbing over the gate, Officer Hymon then shouted "Stop, POLICE"! Garner failed to obey what he was told to do and as a result, Garner was shot in the back of the head. Garner was later pronounced dead and in his possession he held a purse and ten dollars.
Nelson V. The City of Davis (2004)
On April 16, 2004, what was supposed to be known as the "biggest party in history" took place at the annual UC Davis picnic. Due to the large amount of participants at this party, people began to illegally park their cars. Sgt. John Wilson demanded that officers start to issue parking tickets to the illegally parked cars. Tickets were also issued to the underage drinkers. Wilson called the owner of the apartment complex because of the disturbances that were being caused; loud music and the sounds of bottles breaking. Sgt. John Wilson was consented by the complex apartment owner to have non residents to leave the complex. 30 to 40 officers were rounded up with riot gear - including pepper ball guns - to try and disperse the crowd of 1,000 attendees. The officers gathered in front of the complex where 15 to 20 students, including Nelson, were attempting to leave, but no instructions by the police were given. Pepper balls began to fly, one of which struck Nelson in the eye. He collapsed immediately and was taken to the hospital much later on, where he suffered multiple injuries including temporary blindness and a permanent loss of visual acuity. He endured multiple surgeries to try and repair the injury. Nelson was forced to withdraw from UC Davis, losing his athletic scholarship due to the injury he sustained. The officers were unable to find any criminal charges against Nelson.
Studies have shown that law enforcement personnel with some college education (typically two-year degrees) use force much less often than those with little to no higher education. In events that the educated officers do use force, it is usually what is considered "reasonable" force. Despite these findings, very little - only 1% - of police forces within the United States have education requirements for those looking to join their forces. Some argue that police work deeply requires experience that can only be gained from actually working in the field.
It is argued that the skills for performing law enforcement tasks well cannot be produced from a classroom setting. These skills tend to be better gained through repeated exposure to law enforcement situations while in the line of work. The results as to whether or not the amount of experience an officer has contributes to the likelihood that they will use force differ among studies.
It has not been strongly found that the race, class, gender, age etc. of an officer affects the likelihood that they will use force. Situational factors may come into play.
Split-second syndrome is an example of how use of force can be situation-based. Well-meaning officers may resort to the use of force too quickly under situations where they must make a rapid decision. 
Policies on use of force can differ between departments. The type of policies established and whether or not they are enforced can have an impact on an officer's likeliness to use force. If policies are established, but not enforced heavily by the department, the policies may not make a difference. For example, the Rodney King case was described as a problem with the departmental supervision not being clear on policies of (excessive) force. Training offered by the department can be a contributing factor, as well, though it has only been a recent addition to include information on when to use force, rather than how to use force. 
One departmental level policy that is currently being studied and called for by many citizens and politicians is the use of body cameras by officers. In one study body cameras were shown to reduce the use of force by as much as 50%.
At the micro level, violent crime levels increase the likelihood of law enforcement use of force.
England and Wales
"A person may use such force as is reasonable in the circumstances in the prevention of crime, or in effecting or assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large".
Use of force may be considered lawful if it was, on the basis of the facts as the accused honestly believed them, necessary and reasonable.
