Happened when wife and I were newly married. Friend of hers was dating Danny from the Ticket. Wife got the call late at night that one of Danny's friends had been killed. Forget the band he was in, but he was a tall guy and on some type of addiction meds. Meds he mixed with alcohol. Went into a delirious state, started attacking his girlfriend who managed to get him out of the house. He's all amped up and goes to the neighbors house by mistake. Banging on the door, screaming, probably lots of expletives including threats of violence. Neighbor fires a "warning shot" through the door. Aimed high. Didn't account for the fact that this guy was 6'5+. Right in the forehead....
Tragic ending by an idiot homeowner and an idiot on drugs. Made the DFW news, etc. Castle doctrine states you "can" protect your house, etc....but jesus man, just call the cops, hopefully you have an amped up dog, and just sit back in an secure location, watch the door, and wait. Until your house is breached, you are still ok.
