“In states like Connecticut that did [implemented licensing laws], they saw 40 percent drops in gun violence and 15 percent drops in suicides.”
— Cory Booker
Booker is referring to two different studies about the effects of a 1995 Connecticut law that required handgun purchasers to get a license. Researchers found the law was associated with a 40 percent reduction in homicides in Connecticut between 1996 and 2005. A second study found a 15.4 percent reduction in suicide rates associated with the law.
But as the Fact Checker has previously reported, single-state studies may show improvements in gun violence, but the results can’t be readily generalized to other states.
