Yeah I understand why you want them when LEO show up. I don't want someone else's castle trespassed either. I'd rather not have to kill someone either but if you're in my house uninvited and I don't know you then all bets are off and someone is getting shot.
And truth be stated.....I do not want to ruin my castle by shooting someone inside of it. That taint might never go away.
I am and always have been a hands on guy. If I get close and you are not openly armed then decisions will be made as to snatch you up and "Detain" or use lethal force.
My son "Detained" an intruder some time ago with a Louisville slugger. He was armed but opted for a more personal approach. It was most effective. And very painful.
