A few years back we had a guy blow away another guy who was the ex-boyfriend of the shooters lady friend through a door. He used a 12 ga IIRC. The Grand Jury no billed it. Think about that, this is NEW YORK, the guy never got into the house, he got shot through the door with no face to face confrontation and that was the end of it.
I doubt I would walk so easily, but it does make you think about the supposed problems we face.
