Graham v. Connor

Whether police used too much force is judged by what a "reasonable officer" would have done given the circumstances at the moment force was used — not with hindsight. Three factors: severity of crime, whether suspect posed immediate threat, whether suspect was resisting.

Claims of excessive force by law enforcement are analyzed under the Fourth Amendment's "objective reasonableness" standard.

Sets the national standard for all excessive force claims. Every use-of-force case is evaluated against this "objective reasonableness" test.
