I usually stay away from this sort of thread. But, some members I respect have said a couple of things that gave me pause. I've been prompted to waste a few minutes.
While I agree that shooting someone would be a horrid experience, I don't agree with giving a potential preditor any heads up (target indicators). I will attempt to intimidate them into fleeing, only after I've silently dialed 911 and covertly readied arms... and the perp is under my tactical advantage.
No rational person will be sneaking about my home at 4 a.m. I will count on the Mook becoming rational after I have the advantage, not prior to.
Check your feelings at the door, we have a job to do
