Under U.S. law the fleeing felon rule was limited in 1985 to non-lethal force in most cases by Tennessee v. Garner, 471 U.S. 1. 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.''

Can we conclude that can police use deadly force on a fleeing suspect?
yes
