The case of United States v. Swann involved local police officers in Maryland. The police officer felt a hard object in Swann's left sock; the object was a stack of five credit cards belonging to a theft victim. A full search following the arrest produced a canister containing crack cocaine. The defendant moved to suppress the credit cards and cocaine. However, the court ruled that the seizure was proper, because a reasonable police officer could justifiably have believed that the item in the sock was a weapon. The test is whether a reasonably prudent and competent police officer would have regarded the seizure as reasonable, with due regard to the particular circumstances.
