Whether a police officer may conduct a full search of the person incident to a lawful custodial arrest, even when the arrest offense is one for which the officer is unlikely to find evidence on the arrestee.
Holding
Yes. A lawful custodial arrest based on probable cause authorizes a full search of the arrestee’s person without additional case-specific justification.
Reasoning
Search incident to a lawful arrest is a traditional exception to the Fourth Amendment’s warrant requirement. The Court’s precedents, from Weeks through Chimel, consistently recognized an officer’s authority to search the person of a lawfully arrested individual, even though those cases more actively disputed the permissible search area beyond the person.
The D.C. Circuit incorrectly treated the search as if it were a Terry stop-and-frisk. Terry authorizes a limited weapons search despite the absence of probable cause to arrest, and therefore confines the search to what is necessary to locate weapons. A custodial arrest, by contrast, is a substantially greater and different intrusion that carries distinct governmental interests.
The authority to search incident to arrest rests both on the need to remove weapons and the need to preserve evidence. The absence of likely evidence of the particular offense does not eliminate the officer-safety justification or convert the full-search rule into the narrower Terry standard.
A custodial arrest places the officer and arrestee in continued close contact during transportation and booking. That extended exposure creates a danger distinct from, and often greater than, the brief encounter involved in a Terry stop. The Court declined to make the permissible scope of a search turn on an after-the-fact assessment of how likely a particular arrestee was to possess a weapon or evidence.
The Fourth Amendment does not require courts to litigate the necessity of every step of every search following a custodial arrest. Once a custodial arrest based on probable cause is lawful, the arrest itself supplies the authority for a full search of the person; that search is reasonable under the Fourth Amendment as well as exempt from the warrant requirement.
