I hope you get some kind of redress in some fashion and I can't tell you how much I sympathize with you.
It happened to me in 1976. Except I had just gotten home and heard a floor squeak upstairs.
I found small wet spots on the 1st floor carpet, called mother to ask if she had had her little dog over and she said 'No.'
I went upstairs w/gun out, saw BR door near closed, cocked gun and swung in BR door, went around bed facing closet and saw him crouched in the closet with his hands covering his face - a neighbor 35 yrs old and a junkie - saying 'Please don't shoot me!"
Believe it or not, the only thing that went thru my mind was "They ruined my trigger," since I had just gotten my Python back from Colt 2 days prior for a broken hammer spur. (I later discovered my 1911 on the closet floor, out of the case w/ a loaded magazine on the floor next to it!)
Believe me, I still think about that night on occasion. It is a violation that honest poeple don't deserve, no matter how you look at it, and we should not have to take it.
Sincerely wishing you all the best...Maybe you were lucky you did not surprise them.
