This sort of thinking always astounds me. It essentially boils down to "I felt safe when only people willing to break the law were carrying concealed, but now that anyone who is willing to be photographed, fingerprinted, and background checked can legally carry, I suddenly feel like I'm in danger."Yeah, I don't understand the mindset, either. This kind of cognitive dissonance can only happen when people let their feelings override their rational thought.
If they felt safe then, they ought to feel safe now. If they don't feel safe now, then maybe they ought to realize that their previous feelings of safety were just a comfortable illusion.
