Please understand that what I am about to say is intended to be helpful, not critical. I believe in your and my right to self-defense.

I hope you are never involved in a deadly-force situation and most of us never will. However, if by some stroke of fate you are and some over-zealous prosecutor decides that you "had it in" for the scumball that broke into your house and goes searching around the internet for your opinions on such issues, you don't want him finding that post.

The internet is not as anonymous as we think it might be. I never write anything that I would not want a judge to see.

In the situation you described, if I could determine that the threat had ended, I would render first aid to this individual and hope he lived. And believe me, I'm not a bleeding-heart criminal coddler. Some LEOs involved in use of deadly force are never able to come to terms with it and leave the profession. Its something to be avoided if at all possible and, at least for me, has led me seek to become more proficient in less-lethal responses.

As always, YMMV.
