First incident was at my home at around 10pm, where I heard someone trying to open my front door. I peaked through the front blinds, made eye contact with a guy in a white t-shirt, and then he went sprinting around the back side of my house. I grabbed the phone and grabbed a handgun and went to close the backdoor, since only the glass storm door was closed due to the nice weather. By the time I got to the back door he was on my back patio. He reached into his pocket and pulled out a shiny piece of metal and I shot him once, center mass, through my storm door and he crumpled. I called the police, the guy was all strung out on drugs and had a mile long wrap sheet of burglary and assault. Turns out he had a screw driver in his hand. The police were great about the whole thing. Sucked having to replace a screen door and go testify in court at his trial though.
Second incident was out in the the Oak Lawn\Cedar Springs area of Dallas, around 11pm. I was walking through the Kroger parking lot on my way to a drag show and as I rounded the corner I saw a group of big guys beating the shit out one much smaller guy on the hood of a car. I shouted at them, "What are you doing?" I got a mixture of "Fuck off" and "fuck you" and replied with "Leave him alone." That's when two of them turned towards me and started advancing, less than 20 feet away. I was admittedly a little quick on the trigger and fired one round that hit one of the guys low in the gut. He fell and his buddies all bolted. DPD was there within 3 minutes, since that's a heavily patrolled area. It turns out it was a gay bashing I interrupted (this was in the gay part of town.) The poor kid getting beaten lost his vision in one of his eyes, after spending a week in the ICU. DPD was very professional, though at the time I was a reserve police officer for my home town, so that might have given me some credibility with them. I lost my handgun for a couple weeks. The guy that was arrested gave up his friends' names and they were all charged with aggravated assault with the (new at the time) enhancement of a hate crime.
Both of these incidents happened nearly 10 years ago now. But yeah, I sure am a blood thirsty monster. Both of those situations would have been SO much better if I didn't have a gun, or didn't have the will to use it.
