Obtaining a legal license to carry a concealed handgun is very, very difficult. In Georgia, the state with the highest concealed handgun carrying population by volume, something like only .005% of the people have licences, and only around half of them actively carry. These people include private security, off duty or retired cops, ex military, et cetera.
I understand peoples' alarm when it comes to laws like this, because most of the time all people see is "LEGAL TO CARRY HIDDEN WEAPONS!!!", and assuming that every nutcase with an intense desire for self preservation would be carrying a Glock in their pocket blowing peoples' heads off is very, very scary. But the fact is it's REALLY feckin' hard to get a permit. (Legal does not mean easy)
And, IMO, legal concealed weapons take a backseat in ridiculousness/outrageousness to the right for a burglar to break into your home, hurt himself, and sue you and the restriction in most states against you doing anything to harm the burglar once he enters your house.
