A nickname for a British policeman is a bobby, after Sir Robert (Bobby) Peel, who founded Britain’s Metropolitan Police Force in 1829, provoking complaints about the infringement of civil liberties. The first patrolmen wore a blue uniform (to distinguish them from the military who wore red) with a top hat. They also carried a 20-in (51-cm) truncheon (club) for protection, and a rattle for attracting attention—rattles were replaced with whistles in 1886, after experiments showed that whistles could be heard from a much greater distance.
