In Herring v. United States, No. 07-513, the United States Supreme Court upheld the United States Court of Appeals for the Eleventh Circuit holding that the exclusionary rule does not bar evidence seized after an arrest based upon a recalled arrest warrant. The warrant had been recalled by the court, but the withdrawal was never entered into the police computer system. By the time the police realized the mistake, the arrest and seizure of drugs and a weapon had already been made. In a 5-4 decision, the Court held that police mistakes leading to an unlawful search, which are the results of isolated negligence rather than systemic error or reckless disregard of constitutional requirements, do not require the application of the exclusionary doctrine.
