Handgun Licensing More Effective at Reducing Gun Deaths Than Background Checks Alone
New Johns Hopkins white paper and infographic explain that how the background check is carried out is key to reducing gun violence
A new white paper from the Johns Hopkins Center for Gun Policy and Research at the Johns Hopkins Bloomberg School of Public Health concludes that of the approaches used by states to screen out prohibited individuals from owning firearms, only purchaser licensing has been shown to reduce gun homicides and suicides. Purchaser licensing is currently used by nine states and Washington, D.C.
The white paper, “The Impact of Handgun Purchaser Licensing Laws on Gun Violence,” and an accompanying infographic explain that states generally use three approaches to screen out prohibited individuals from purchasing firearms: 1: the minimum that federal law requires—mandatory background checks for sales from a licensed dealer; 2: comprehensive background check requirements that also cover private-party transfers of firearms; 3: a background check for all firearm transfers as a complement to a licensing or permit system. Some states with comprehensive background checks or firearm purchaser licensing limit these requirements to transfers of handguns.
“Licensing differs from a standard background check in important ways, and the purpose of issuing this white paper and infographic is to clear up confusion about the efficacy of these laws,” says the report’s lead author, Cassandra Crifasi, PhD, MPH, deputy director of the Johns Hopkins Center for Gun Policy and Research and assistant professor in the Bloomberg School’s Department of Health Policy and Management. “Comprehensive background checks are a necessary component of any system designed to keep guns from prohibited persons, but they are insufficient to reduce firearm-related deaths without a complementary system of purchaser licensing.”
In general, states with licensing require prospective gun buyers to apply for a license with a state or local law enforcement agency, pass a background check, often submit fingerprints, and, in some cases, show evidence of gun safety training. States with licensing typically have more thorough processes for checking backgrounds, allow law enforcement more time to conduct those checks, or have mandatory waiting periods.
In contrast, the mandatory federal background law requires that a prospective buyer undergo a background check if they purchase a firearm, but only if they purchase it from a licensed dealer. Other key differences among the three approaches are highlighted in the report’s companion infographic.
To date, available research shows that states with comprehensive background checks that are not part of a licensing system experience fewer guns diverted to criminal use. However, research to date has not shown that background checks alone lead to significant reductions in gun-related deaths.
In comparison, earlier research from the report authors showed that when Missouri repealed its handgun purchaser licensing law in 2007, homicides rose an estimated 17 to 27 percent through 2016. A separate study found the repeal was associated with a 16 percent increase in firearm suicides through 2012. In contrast, when Connecticut enacted a handgun licensing law in 1995 to supplement its universal background check policy, the state experienced a 40 percent decrease in gun homicides and a 15 percent reduction in gun suicides over the first ten years the law was in effect.
“The most likely reasons we see impacts on firearm homicides and suicides for licensing and not for comprehensive background checks witout licensing center on the more direct interface between prospective purchasers and law enforcement and more robust systems for background checks,” says report co-author Daniel Webster, ScD, MPH, director of the Johns Hopkins Center for Gun Policy and Research and Bloomberg Professor of American Health at the Bloomberg School. “These procedures may deter individuals who might otherwise make impulsive decisions to acquire a gun to hurt themselves or others.”
The white paper posits that one reason advocacy organizations have pushed policymakers to adopt comprehensive background checks (versus licensing) is because of their broad appeal: Polls consistently find that over 85 percent of U.S. adults support comprehensive background checks with no difference between gun owners and non-gun owners.
Yet, says Crifasi, national public opinon surveys also show that three-quarters of adults support laws requiring handgun purchasers to obtain a license from a law enforcement agency, with support among gun owners at 60 percent.
“Given this level of support among the population, including gun owners, and the robust body of evidence on the effectiveness of licensing laws, policymakers should consider licensing as a key strategy to reduce gun violence in the communities they serve,” Crifasi says.
In addition to Washington, D.C., the nine states that have licensing requirements include Connecticut, Hawaii, Illinois, Iowa, Maryland, Massachusetts, New Jersey, New York and North Carolina.
In the 2018-2019 legislative session, gun purchasing licensing bills were introduced in Oregon, Delaware and Minnesota. Last year, both the U.S. House of Representatives and the U.S. Senate introduced measures that would incentivize states to adopt handgun licensing laws.
