I'd say TG has nailed it.
a CCW permit isn't a license to be a superhero. Yes, I'm sure there ARE CCW holders that dream of being in the gunfight, saving the Girl, and riding off into the sunset. Hell, I'm sure all of us have had that fantasy at some point.
Trick is, that's all it is: a fantasy (at least, I HOPE that's all it is for most). The reality is, most that carry do so simply to protect themselves and theirs. Not to go running off towards the sound of the guns...
