People v. Rivera, 14 N.Y.2d 441 (1964)
Police may stop and question a person based on reasonable suspicion of criminal activity and, as an incident to that inquiry, conduct a limited “frisk” of the outer clothing for weapons if they reasonably believe they are in danger.
Summary
This case addresses the legality of a police stop and frisk conducted before New York’s “stop and frisk” law was enacted. Detectives observed two men, including Rivera, acting suspiciously in an area known for crime. The men looked into a bar window, walked away, returned, and then rapidly walked away when they noticed the detectives. The detectives stopped Rivera, frisked him, and discovered a loaded gun. The court considered whether the police action of stopping and frisking Rivera was justified under the Fourth Amendment, ultimately holding that, under the circumstances, the stop and frisk was reasonable given the need to protect the officers and maintain public order.
Facts
On May 25, 1962, at 1:30 a.m., three plainclothes detectives were patrolling in an unmarked car near 7th Street and Avenue C in Manhattan. Detective Bennett observed Rivera and another man behaving suspiciously for about five minutes. The men repeatedly looked into the window of a bar and grill. Rivera looked towards the detectives’ car, said something to his companion, and both men began walking rapidly away. Detective Bennett described the area as having “quite a bit of crime…Muggings, stick-ups, assaults, larcenies, burglaries.” The detective stopped Rivera and, for his own protection, patted down the outside of Rivera’s clothing, feeling what he believed to be a weapon. He then removed a loaded .22 caliber gun from Rivera’s person.
Procedural History
Rivera was arrested and indicted for criminally carrying a loaded pistol and for criminally possessing a pistol. He moved to suppress the evidence (the gun and bullets). The Supreme Court granted the motion to suppress. The Appellate Division affirmed this decision without opinion.
Issue(s)
Whether police officers, based on reasonable suspicion, may stop and question an individual in public.
Whether police officers, incident to a lawful stop, may conduct a limited search (frisk) of an individual’s outer clothing for weapons when they have a reasonable fear for their safety or the safety of others.
Holding
Yes, because prompt inquiry into suspicious street action is an indispensable police power in the orderly government of large urban communities.
Yes, because the right to frisk may be justified as an incident to inquiry upon grounds of elemental safety and precaution which might not initially sustain a search.
Court’s Reasoning
The Court reasoned that police have a duty to prevent crime and must be able to make prompt inquiries into suspicious behavior. The level of evidence needed for inquiry is less than that required for an arrest. Stopping someone for questioning is not an arrest. The court emphasized, “The business of the police is to prevent crime if they can.” The court recognized the inherent dangers faced by police officers when questioning individuals in public. The court stated, “The answer to the question propounded by the policeman may be a bullet; in any case the exposure to danger could be very great.” Therefore, a limited frisk for weapons is a reasonable precaution to ensure the officer’s safety. The court acknowledged that a frisk is a limited invasion of privacy, but it is less intrusive than a full search. The court balanced the individual’s right to privacy against the need for public safety and the safety of police officers. The Court noted that the constitutional restriction is against unreasonable searches, not all searches, and that reasonableness requires a balancing of interests. The court concluded that the precautionary procedures followed by the police in questioning Rivera met the practical demands of effective criminal investigation without being unreasonable.
