   As of January 1, 2013, the United States had a total resident population of 316,809,000. Which means that there is approximately 1 law enforcement officer for every 414 people in the U.S.

   What do you think your chances are that a law enforcement officer is going to be able to assist you at the time when you really need it most? What do you think your chances are if you have the capability of defending yourself, family, and property? It's also worthy of notice, that a firearm is much easier to carry than a cop. And you statistically have a far better chance of stopping/surviving a criminal attack. IF you are enabled to make an effective defense. It's not only just plain common sense, but a RIGHT and a duty.
