I do think we tend to get cause and effect mixed up a lot when we start to identify CCWers. Hey, most CCWers have two hands, that must be a threat indicator!
The hate for fanny packs is a great example. Whenever someone tells me he "knows" all fanny packs carry guns, I just roll my eyes. I live in a state where few people want to carry guns and far fewer are allowed to CCW. But I see fanny packs at the mall, the dog park, and on folks walking up and down Main Street all the time. You're telling me these people are all armed?
