This question has been thrown around a lot lately along with, "Why does anyone need a weapon that can hold more than 10 rounds?". Here's a video of some guys defending a market from looters during the LA riots. It seems to have worked for them to have an uzi. Ask yourself, what / who are you going to turn to if the police can't protect your house, family and food? If you say it can't happen look at LA just shy of 21 years ago. http://www.youtube.com/watch?v=a6tmD0W5r4w
