More Guns, Less Crime is a book by John Lott that examines how violent crime rates change when states pass "shall issue" concealed carry laws. Lott examines the effects of shall issue laws on violent crime across the United States. His conclusion is that shall issue laws, which allow citizens to carry concealed weapons, steadily decrease violent crime. He explains that this result makes sense because criminals are deterred by the risk of attacking an armed victim. As more citizens arm themselves, the danger to criminals increases.
A conference organized at the conservative American Enterprise Institute by John Lott resulted in a special issue of The Journal of Law and Economics. A number of papers from that conference supported Lott's conclusions:
*Bruce L. Benson, Florida State University, and Brent D. Mast, American Enterprise Institute, 'Privately Produced General Deterrence', The Journal of Law and Economics, October 2001
*Florenz Plassmann, State University of New York at Binghamton, and T. Nicolaus Tideman, Virginia Polytechnic Institute and State University, "Does the right to carry concealed handguns deter countable crimes? Only a count analysis can say", The Journal of Law and Economics, October 2001
