I had a thread where I told the details of pointing my shotgun at a drunk kid who had broken into my apartment. He and his buddy took off when one of my roommates said that he was calling the cops.
That happened 8 years ago. I made a lot of "tactical" mistakes in that brief encounter. No body got hurt. The cops got called and the drunks got arrested later on.
I received some good advise from that thread but I was shocked by the number of responses that told me that I had made a mistake by not taking the lives of two guys who were out numbered, out gunned (they were unarmed), and so drunk they could hardly stand.
