Illinois v. Lafayette
Defendant was arrested for getting into an altercation with a theater manager. While booking him, police had him place all belongings on a counter. These included a shoulder bag, in which police found ten amphetamine pills.
Can police search the personal effects of a person as part of the procedure incident to booking and jailing the person after a lawful arrest?
The individual's Fourth Amendment interests must be balanced against the government's interests in proper handling of taken items, preventing liability to claims of theft, and detecting items that could pose a danger to the arrestee or others.
Routine inventories of a person's personal effects at booking subject to standard police procedure are reasonable under the Fourth Amendment.
