Rolo]All of this stuff is based on fear, and as far as I can tell by reading about it, concealed carry laws have meant almost nothing towards increasing or decreasing crime.
Pro-gun guys say "an armed society is a polite society". Anti-gun guys say "omg, every Tom, Dick and Harry will have a shootout at the 7-11!!"
Both are simplistic assholes if you ask me. And since I was curious, I went and found an article full of scholarly examinings of the findings of the effects on crime in states that have passed concealed carry laws. Interesting read, and seems to support the idea that there is no significant impact, good or bad, on overall crime in states that have the laws.
