This is probably one of the more amazing stories I've read lately. A victim tricks a robber into giving up his sawed-off shotgun ... then proceeds to beat, strip and rob the guy who had been trying to rob him.
Everything goes smashingly until the shotgun, which is being used to beat the robber, goes off and hits the "victim" in the stomach, killing him. The robber ran away naked.
