I am a LOT more concerned about a person who carries a concealed weapon without a permit than one who carries with a permit. The former is far more likely to use the gun in an untoward way than one who subjects themselves to the background check required for the permit. Reason? If they carry without a permit they already scoff at the law, but if they carry with a permit they take positive action to comply with the law. As for your "many millions" claim, you unsupported exaggeration only weakens your argument.
i have no statistics to support the following claim but will be willing to bet a Krystal burger that there are far more concealed guns being carried than you would ever imagine and that the great majority of them are carried without permits. If you truly knew how many are out there, based on your approach you would never leave your home.
