Fact: there are guns in the US. Fact: those who use them for evil are themselves evil and don't buy registered guns from a dealer. Fact: is most cases and especially when TSHTF, police and government will not be there to protect US citizens. You can call 911, but you still have to wait. How will you protect yourself and your family until the police arrive?

The good (unarmed) people of NO became victims. If the looters couldn't find guns, they would have stabbed or stoned those people to death, because that what desperation (or evil) promotes. A gun is merely a tool of the act, the same as a rock. It just happens to be much more effective.
