In common law, the fleeing felon rule permits the use of force, including deadly force, against an individual who is suspected of a felony and is in clear flight.
Under U.S. law the fleeing felon rule was limited in 1985 to non-lethal force in most cases by Tennessee v. Garner, . The justices held that deadly force "may not be used unless necessary to prevent the escape and the officer has probable cause to believe that the suspect poses a significant threat of death or serious bodily harm to the officer or others."
Fleeing felons may be followed into places not open to the public without a warrant if the officer is in "hot pursuit."
