I'd also like to point out that in some states CCWs are public record( by name in states like OR) Some are just listed by number, and others are Can not be released by state law. Places like AK and vermont do have CCW permits... There are way to many "road blocks" to get any type of solid stats when it comes to CCW, or firearms in general.
As much as I would love to say that X ammount of CCW stops Y ammount of crime, its does not work that way.
Just something to think about for all you "true beleavers"
