Finding a burglar in your living room with arms full of your DVD or china?
Is that a life and death shoot'em? One should consider that. You do have some time. While some folks will say "Castle" and blast him - think that is an always and useful response?
I, for one, will not kill for property. Regardless of whether the law allows it. Assuming your scenario, I would probably raise my gun and say "Stop Right There!" or something similar. If he stops - great, if he runs away - great. If he drops everything and heads my way, now he probably gets shot- especially if he's got a weapon.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
