CHICAGO (March 6, 2013)--A 50-state study published online Wednesday in JAMA Internal Medicine journal says states with the most gun laws have the fewest gun-related deaths.
“A higher number of firearm laws in a state are associated with a lower rate of firearm fatalities in the state, overall and for suicides and homicides individually. As our study could not determine cause-and-effect relationships, further studies are necessary to define the nature of this association,” the researchers concluded.
The research doesn't prove that the number of laws makes a difference, and some experts say this kind of comparison is hard to do because states are different in so many ways.
The authors from Boston Children's Hospital and Harvard University analyzed four years of government data and data from a gun control advocacy group.
The study comes as policymakers at every level are weighing how to respond to recent high-profile acts of gun violence.
