I believe that most of us who own and carry firearms would not do this. Unless I was in fear of my life I would refrain from shooting someone over belongings. However, the more that criminals perpetrate their trade, the more frustrated law-abiding citizens get and leads to this sort of event.
Like Lima said, I digress. I can recall a time when people had respect for property of others and we used to go away from our home with the door wide open, covered only by a wooden screen door and nobody dared enter because they had respect. Apparently respect is no longer fashionable, but again I digress.
