The tax payers spent untold amounts of dollars to train me. The least I can do is continue to help defend the defenseless even if I'm under armed and armored for the job. I would rather die trying to defend someone then live with my inaction or inability to do so.
That's my attitude, many don't like it and think that I'm paranoid for carrying because the chance of something happening while i'm in a position to do something is slim to none. Very true, but if most people were prepared then the chance of someone being there to stop something truly awful from happening would grow exponentially.
