24/7 Wall St. discussed the CDC’s figures with John Roman, senior fellow at the Urban Institute, an economic and social policy think tank. Roman explained the probability of accidents, suicides, and domestic violence goes up in homes with guns. Americans are “three times more likely to have a suicide in a home with a gun than [they] are in a home without a gun.”
According to Roman, “The overwhelming trend is that strong gun law states have seen dramatic declines in violence. Weak gun law states have not seen the same decline.” While stricter gun laws lead to less violence, Roman noted, this relationship is not exactly straightforward, because people may purchase a gun in one state and bring it into another. “As long as there are weak gun law states, even strong gun law states will see gun violence.”
Although not necessarily gun related, violent crime, overall, was higher in many of these states. Seven states reported at least 420 violent crimes per 100,000 residents in 2011, versus the national rate of just 386.3 violent crimes per 100,000 residents that year. There were more than 600 violent crimes per 100,000 residents in Alaska, second only to Tennessee. Some specific crimes were even more likely in many of these states. Six of the 10 states reported more than 3,500 incidents of property crime per 100,00 residents, for example, versus a national rate of just 2,908.
Perhaps the authors have been reading our never-ending discussions about gun-violence rates vs. overall violence. In this article they've covered it pretty well.
