If an intruder breaks into my home, I’m going to assume that he’s come prepared to run into family members. That means he may be armed, and probably is.
Also, the home is a very close quarters. If you confront someone, there isn’t going to be a lot of time for negotiations, or space to run away.
All this adds up to this conclusion: If I confront someone who has broken into my home, I WILL assume that deadly force is justified, unless I’m offered incontrovertible evidence to the contrary. The burden of proof is on the burglar to offer that evidence.
Back when it was just my wife and myself, our drill was that if someone broke into the house, we would simply barricade ourselves in the bedroom, with the 9mm at our side. Announce to the burglar that we were in the house, and armed, and that he should leave immediately. Then wait for him to leave.
If he didn’t leave but chose to enter the bedroom after being warned, he would be greeted with a volley of lead. End of story. I’m not going to wait to see his gun. Sorry. Take me to court.
But now that I have a daughter in another bedroom, the situation is different. Upon hearing a break-in, it’s straight to the daughter’s bedroom to collect her, armed if possible. If, along the way, I encounter the intruder, he will be shot. Period. I’m not about to try to engage an intruder in conversation in close quarters. My daughter’s life is at stake. I’ll go to jail if I have to.
If, on the other hand, I can collect our daughter and make it back to our bedroom, then plan A goes back into effect.
What I’m not going to do is go searching the house like Rambo, seeking out a confrontation with the intruder. That’s idiotic. He can take the damned TV if he wants it that badly. But if the encounter happens despite my attempts to avoid it, I’ll shoot first and ask questions later.
