Same deal with the 4 armed guys breaking into my apartment. One died. He was shot twice in the chest with 9mm JHP rounds. He was able to run out the door and to the other side of the apartment building before he collapsed and died. That 20 or 30 seconds it took him to do that, he could have emptied all the rounds out of his gun into either me or my roommate. A threat is not neutralized until it is immobile or dead. In some situations, it may be a good idea to push the BGs firearm far out of his reach with your foot if you can do it safely.If you've ever shot or seen someone shot "not on tv mind you", unless you've hit a vital organ, the assailant may still be a conscious and/or a threat.
Its a good read though. I like the idea of immediately taking cover if its available. You never know if the BG had a partner near by, or if an off duty LEO or CCW holder will mistake you as a BG and open fire on you. However I never though of yelling "I shot in self defense" immediately after shooting. Thats a really good idea.
