Police in Washington, D.C., put a GPS device on a suspected drug dealer’s car and — without getting a warrant — used the tracking system to follow his movements day after day for a month.

The U.S. Court of Appeals for the District of Columbia Circuit has held that using GPS in this way violates the Fourth Amendment’s protection against unreasonable searches and seizures. Other courts, however, have held otherwise.
What will the U.S. Supreme Court say?
