I almost thought that was a joke when I read it. In any case, the bullet took an odd path to reach the robber's head. He won't be terrorizing anyone else from now on.
That's what I thought. What are the odds of a bullet fired a few feet away (probably) entering a hole about 1/2"?
When I was a dumb teen we used to set up Coke bottles horizontally on a post with the mouth facing us and try to shoot out the bottoms with a .22 without hitting the sides. Never made it.
