I hate to say this, but this proves the idea of having SHTF supplies. Granted, you might have to do some diving in your own house to get your ammo can, but at least you'd be able to defend yourself from looters. Figure that most if not all the street gangs and criminal element stayed in NO. The honest law abiding people weren't worried about taking their guns (if they had them) to shelters. They were just trying to stay alive. Now, the criminals have unarmed people to exploit and out number the police force. I saw one report from the converntion center that they were stealing water and selling it back to the people they stole it from for $5 a bottle.
I can understand and even condone people looting food and water to survive. I just haven't figured out how jewelry and electronics do anything. Unless maybe you trade that with other looters for food and water.
These armed gangs need to be shot on sight.
