No...armed citizens, and the public in general, have to realize these are complex situations. The police are tasked with dealing with this sort of problem. It's their job. Armed citizens are not. If you're getting a permit because you think you're going to "assist" the police and stop crime, you need to rethink your motives.
And I'm all for people carrying guns. I just want them to put their brain in gear before putting their gun in gear.
