Patrolman
From Tardis Wiki, the free Doctor Who reference
An I.E patrolman was patrolling around the I.E. compound owned by Tobias Vaughn. He came across a lorry driver (really a UNIT spy) and tried to arrest him because he didn't have a pass. The driver said only the police could arrest him, so the patrolman and the others on patrol shot the driver and killed him. (TV: The Invasion)
