In Drogheda, Ireland, after trying to break into a car by throwing rocks at a car window, a man picked up a brick and threw it. It bounced off and hit him in the face. The owner of the car found the man lying on the ground bleeding. The car owner called police after the man demanded he give him cab fare. When the police arrived, the man tried to claim the car owner assaulted him, but the car owner also owned the pub he was parked in front of and was able to get surveillance video footage of the man injuring himself. You can see that footage here.
