Yes it deters. As George Orwell said "people sleep peacefully in the beds at night knowing that rough men stand ready to do violence on their behalf". Whether it is the soldier across the ocean, the cop down the street, or you with a weapon in your home, the threat of greater force will deter all but the mentally deranged. Yes it might also move the crime to more vulnerable people. The criminal mind is evil. That can't stop us from defending ourselves and our loved ones. Just my opinion.NormanB said:.....does it really deter? Or does it move the crime to a less 'hostile' /more vulnerable (like old people) area?
