Whether the warrantless search of Preston's car at a garage, after the occupants had been arrested and taken to the police station, was valid as a search incident to arrest.
Holding
No. The search was too remote in time and place from the arrests to qualify as a valid search incident to arrest.
Reasoning
The Fourth Amendment generally requires a warrant before officers search, subject to carefully defined exceptions. A lawful arrest permits a contemporaneous warrantless search of the arrestee and items within the arrestee's immediate control. That limited authority protects officers from weapons, prevents escape, and preserves evidence that could otherwise be destroyed.
Those justifications did not exist when police searched Preston's car. Preston and his companions had already been arrested, booked, and held at the police station, while the car was securely in police custody at a garage. The men could no longer reach weapons or evidence in the vehicle, destroy its contents, or drive it away.
Even assuming that the initial arrests were valid, or that police had probable cause to believe the car was stolen and therefore could have searched it when they first encountered it, that assumption did not validate the later garage search. The reasonableness of a search must be assessed at the time and place it occurs. Because this search was separated from the arrest in both time and location, officers needed a warrant before conducting it.
