Dunaway v. New York

Background

A man in Rochester was suspected in a pizza-parlor killing after an informant gave police a lead that did not supply enough information for a warrant. Detectives went to a neighbor’s house, took him into custody without telling him he was under arrest, and drove him to the police station. At the station he received Miranda warnings, waived counsel, and made statements and sketches that implicated him.

Reasoning

The Court addressed whether taking a person into custody and transporting him to the station for questioning without probable cause violates the Fourth Amendment’s protection against unreasonable seizures. The Justices held that such a seizure is equivalent in seriousness to an arrest and therefore requires probable cause. The Court also explained that Miranda warnings alone do not automatically remove the taint of an illegal seizure; the prosecution must prove the connection between the illegal act and the confession was sufficiently broken. In this case the record showed a quick, purposeful detention with no significant intervening events, so the statements remained tainted and inadmissible.

Real world impact

The ruling prevents police from using confessions obtained after bringing someone to the station without probable cause. Police departments and prosecutors will have to ensure probable cause before making custodial stationhouse interrogations. Defendants gain a stronger basis to suppress statements taken after such illegal detentions. Because the Court applied the rule on these facts, the decision clarifies but does not foreclose future fact-specific disputes about attenuation.

Dissents or concurrances

Several Justices wrote separately. Two concurring opinions emphasized reasonableness and practical rules for police; a dissent argued the record showed the man went voluntarily and that the statements were sufficiently independent. These opinions explain differing views about how to weigh police conduct and safeguards.
