Dragnet

The Shooting Board (2x2)

:

Joe stops at an all night launderette to buy cigarettes and interrupts a burglar working the coin changer. When he shouts "Freeze," the criminal comes up shooting. Joe returns fire, hitting the man, who flees with the help of his girlfriend. He's later found dead. When SID tries to find the bullet fired at Joe, they come up empty and Joe faces a shooting board with no proof the man ever fired at him. A great surprise ending.
