How about this reason:
John Lott and David Mustard, in connection with the University of Chicago Law School, examining crime statistics from 1977 to 1992 for all U.S. counties, concluded that the thirty-one states allowing their residents to carry concealed, had significant reductions in violent crime. Lott writes, "Our most conservative estimates show that by adopting shall-issue laws, states reduced murders by 8.5%, rapes by 5%, aggravated assaults by 7% and robbery by 3%. If those states that did not permit concealed handguns in 1992 had permitted them back then, citizens might have been spared approximately 1,570 murders, 4,177 rapes, 60,000 aggravated assaults and 12,000 robberies. To put it even more simply criminals, we found, respond rationally to deterrence threats... While support for strict gun-control laws usually has been strongest in large cities, where crime rates are highest, that's precisely where right-to-carry laws have produced the largest drops in violent crimes."
