Concealed Carry
Persons who are issued concealed carry licenses are far more law-abiding than the general population. One reason is obvious: permitees are a self-selected group of people who are scrupulous about legal compliance.
Persons who apply for a concealed carry permit have chosen to spend a substantial amount of money and time (for fees, training, application, fingerprinting) to get a card from the government; that card legally authorizes the person to do something (carry concealed) which the person could do anyway, with almost no chance of getting caught.
David Kopel at the Independence Institute recently published a 7-page paper titled Licensed Handgun Carry for Young Adults Serving in the Armed Forces that examines a proposal to allow young adults, aged 18-20, to apply for concealed handgun carry permits, if they currently or previously served in the United States Armed Forces. The paper is available in PDF at the above link.
