United States v. Hensley, 469 U.S. 221 (1985)
The case of United States v. Hensley marks a significant moment in the interpretation of Fourth Amendment rights concerning police authority and the concept of reasonable suspicion.
Does the Fourth Amendment permit police officers to make a stop based on reasonable suspicion derived from another police department's bulletin, even if the suspicion is related to a completed crime?
Under the Fourth Amendment, police officers can conduct a stop if they have reasonable suspicion, a standard set forth by Terry v. Ohio. This reasonable suspicion can extend to detentions based on information from another jurisdiction's police bulletin.
The Supreme Court held that a stop based on reasonable suspicion from another police department's bulletin is valid under the Fourth Amendment, as long as the underlying suspicion is itself founded on proper investigative grounds.
Hensley is significant as it broadens the understanding of reasonable suspicion in the context of police collaboration across jurisdictions. It reflects the Court's acknowledgment of modern policing challenges and the necessity for relying on the collective information held by law enforcement. For law students, Hensley clarifies the scope of Fourth Amendment rights relating to policing practices and offers insight into how courts balance privacy rights against the needs of law enforcement.
