Fyfe (February 16, 1942 – November 12, 2005) was an American criminologist, a leading authority on the police use of force and police accountability, and a police administrator.
His research on the police use of deadly force has been cited extensively, most notably in the 1985 Supreme Court case of Tennessee v.
Garner, in which the Court ruled as unconstitutional police department policies that allow officers to shoot to kill "fleeing felons" who do not pose an immediate danger to the community.
The Supreme Court cited his dissertation in its majority opinion.
