Halt or I Fire! In 1941 an off duty RAF sergeant decided the car that was driving at speed down Willowbrae Road in Edinburgh during an air raid was breaking the blackout restrictions. He took it on himself to order the car to stop and when it didn't took a shot at it with the rifle he happened to have taken to the pub with him. Unfortunately the shot fatally wounded the Assistant Chief Constable of Edinburgh. The 1995 programme explored the law of culpable homicide and the parallel at the time with the case of a soldier in Northern Ireland who had been convicted of murder for fatally injuring occupants of a car that had failed to stop at a check point.
