Sherman Minton,
United States v. Rabinowitz — Opinion of the Court
“ The mandate of the Fourth Amendment is that the people shall be secure against unreasonable searches. It is not disputed that there may be reasonable searches, incident to an arrest, without a search warrant. Upon acceptance of this established rule that some authority to search follows from lawfully taking the person into custody, it becomes apparent that such searches turn upon the reasonableness under all the circumstances and not upon the practicability of procuring a search warrant, for the warrant is not required. ”
