That's one reason the military is not allowed to act on home soil. Different rules apply.
Actually when you've intruded into someone else's home and attacked their family, I'm totally comfortable with Marine Corps thinking.
If you are the intruder you better hope there are no former marines in your selected home.
I do think the best possible result is not having to use the weapon... But like I said before, that's at the discretion of the home owner.
