This is the ridiculous moment the world’s dumbest criminal knocked himself out with his own weapon during a break-in. Footage shows the would-be thief trying to break a window by hurling a brick at it. But instead of shattering the glass, the missile bounces straight back and hits him squarely in the head. He was captured on CCTV as he swaggered into the restaurant in Prince George's County in Maryland, US, having used the brick to smash the entrance windows.
