BUT, in reality are you really going to just let someone violate you and help themselves to your domain?
Would a reasonable person belive that I'm in danger of receiving grevious bodily harm? Does the assailant have the ability, opportunity, and are they an immediate threat?
Every state law is different. In my "domain" I have the legal ability to exercise lethal force to stop a forcible felony. I even have civil liability protection for any injuries that I cause to a perpetrator as long as said injuries where caused while they were in the commission of a forcible felony except for AUTO BURGLARY.
So I would suggest that you read up on your applicable state laws so that you don't end up like the guy in the first post.
This isn't some little theoretical game I get to play on the internet for fun. I've taught and certified about 400 people to carry concealed firearms. I can't stand in front of a room full of students and talk smack, or make boasts, or tell them how I WISH things were.
I have to tell them how it actually is. In real life.
So if I walk out of my house, and some scumbag is driving off in my car. No I'm not going to shoot him unless I can articulate why I or someone else was in danger of grevious bodily harm.
If the person threatens me in any way, then I will act accordingly.
