When I was a baby our family was in a bad car accident. My dad got out to check the other driver and he apparently stank of whiskey. Dad dragged him out of the car and beat his head off the road.

He admitted it to the police when they turned up, and the police apparently said to him “so that guy must have hit his head on the steering wheel pretty hard then..”. Dad didn’t get in any trouble and the other driver was either too drunk to know what happened or was in so much trouble anyway he never pressed it any further.
