Earl Warren,
Pierson v. Ray — Opinion of the Court
(1967)
“ The common law has never granted police officers an absolute and unqualified immunity, and the officers in this case do not claim that they are entitled to one. Their claim is rather that they should not be liable if they acted in good faith and with probable cause in making an arrest under a statute that they believed to be valid. Under the prevailing view in this country a peace officer who arrests someone with probable cause is not liable for false arrest simply because the innocence of the suspect is later proved. ”
