In Briggs, police obtained a warrant on 'probable cause' that consisted of an unexplored and uncorroborated conversation intercepted by a court-authorized wiretap. Invoking the reasonableness standard, the Court held that officers who arrest without probable cause may be held liable for monetary damages in civil court and that an erroneous judicial decision to issue a warrant did not excuse the unconstitutional police action. While this ruling has angered many police officers, the actual effect of the law will be negligible. The qualified immunity standard has been applied to police before, and police have been held civilly liable in other cases. Further, the decision of reasonableness is made by the judge, and monetary considerations will limit the number of such suits brought. Nonetheless, police perceive the decision in Briggs as an insult to their professionalism. Further, it suggests that police discretion must be limited and subject to controls, while judicial and prosecutorial discretion are not. 21 notes.
