As it turns out, the arrest rate for concealed carry permit holders is less than one-third the rate of the normal population. The key is, does the press pick it up and run with it. Well, the press may be bias, but they aren't stupid. None of the press releases published by the Illinois Council on Handgun Violence have been picked up by the mainstream press for good reason. They claim to have examined the data, but the facts remain, Florida's violent crime rate has gone down each and every year for the past eleven years since implementation of their CCW law.
Proof is in the pudding.
Among the examples of license holders who committed a gun crime after having received a concealed weapons license was Orrin Weiss, who was arrested for aggravated battery and aggravated assault after he held a pistol to his girlfriend's head.
