It may make sense to assume that states in which there are tight laws on weapons would make that state a safer place and one with less gun crime, however, recent research argues that the very opposite is true.
Mark Gius from Quinnipac University, published in Applied Economics Letters, suggests that this is in fact not the case, research shows that in states with more restrictive concealed carry weapons (CCW) laws there is actually an increase in gun related crime.
Over the period of the study the average murder rate was 3.44, data available in the full article indicates that states with more restrictive CCW laws had a gun-related murder rate that was 10% higher than the average. In addition to this finding, the Federal assault weapons ban seemed to make an even bigger impact, with murder rates 19.3% higher when this ban was in effect.
There are four broad types of CCW laws, unrestricted, which means an individual requires no permit to carry a concealed handgun. Shall issue, in which a permit is required but authorities must issue one to all qualified applicants that request one. May issue, in which authorities can deny a request for a permit and finally no issue, those states that do not allow private citizens to carry a concealed weapon.
