We had a situation in my area probably 15 years ago where the homeowners, apparently, assumed the guy was "just there for the VCR" and decided to cooperate with the guy.
His entire family ended up dead with his daughter raped and then the guy poured gas on them and lit the entire house on fire.
Ended of while later with some LE bullets in the guy (actually, last I knew they weren't sure if it was suicide or police bullets)
I think about that situation when I think about whether or not I'd shoot someone entering my home.
