Just last year in Beauregard town (by police HQ) a man stormed the front door and shot a woman dead. It can and does happen.
I wouldn't call the pair that perpetrated that crime men.
They kicked down the front door, shot a mom dead, put five rounds of 9mm in her daughter (about nine yrs old) and made off with a flat screen, on their bicycles. One was caught, the other not.
I'll stop here before I write something that may come back to haunt me.
I carry at home.
