Interestingly, the places most likely to have a large population of potential would-be terrorists tend to be the large urban population centers that restrict the ability of the citizens to discretely arm themselves. Some slob in Manhattan, San Francisco, or Chicago walks into a 7-11 and starts waving a gun around is far less likely to get a bullet for his troubles than if he had pulled the same stunt in, say, well, most red states.
I don’t know whether statistics bear it out or not, but I would think that would-be terrorists are less likely to to get their jihad on when theres a reasonable chance that one of the folks they’re trying to corral into the walk-in freezer has a Glock in the pocket. Certainly having a little ace up your sleeve isnt a guarantee that youre going to get out of a situation like that, but I’d definitely feel my odds were better with it than without.
Of course, these sorts of precautions aren’t limited to worrying about terrorists. Given the increasingly unstable natures of a large portion of the population these days, it’s a good idea to drop the 640 or the G26 into the coat pocket when you walk out the door.
Here in the quiet hinterboonies the odds of some sort of recent immigrant-who-failed-to-assimilate going nuts and holding hostages in the local WalMart is virtually nil. It’s far more likely to be some low-class loser who just got kicked out of the trailer by his babymomma and figures he and his HiPoint will make the world pay. The proper response and solution to the problem, though, remains the same.
