In the aftermath of the two deadly mass shootings in Las Vegas and Sutherland Springs, Texas, Congress should be protecting Americans from gun violence by strengthening our gun laws, not weakening them. Instead, in a party line vote last week, the House Judiciary Committee passed the Concealed Carry Reciprocity Act (H.R. 38), a National Rifle Association (NRA) priority.

CCW1If this bill is enacted into law, each state would be required to honor a concealed carry permit issued by another state, even if the permit holder’s state of residence has much lower standards or no permit requirement at all for those carrying concealed weapons. This would be a dangerous law, as it would allow people to seamlessly carry guns across state lines, regardless of the vetting and training required by the state issuing the permit.

It is ironic that during a period in which gun deaths have been increasing and mass shootings are claiming an unprecedented number of victims, our first national law in many years would prioritize the rights of gun owners rather than enhance public safety. It is also a paradox that we would have a national law that, rather than setting a high national standard for individuals who carry lethal weapons, would instead preserve a system of disparate state laws in which the lowest standard would be imposed on all states. The NRA and Republicans also violate conservative doctrine by undermining the right of states to protect their residents through the imposition of rigorous requirements on gun permit applicants.

Asserting federal authority in gun policy might be worth considering if there was compelling evidence that such an approach would improve public safety. However, research clearly shows that increasing gun carrying offers few advantages and imperils public safety. John Donohue at Stanford University has shown that right-to-carry laws have increased state violent crime rates by 15%. An FBI study of 160 active shooter incidents from 2000 to 2013 found that just one of these incidents was stopped by an armed civilian. Louis Klarevas, author of Rampage Nation, found that just one in every 2,000 potential or actual mass shootings is successfully stopped by an armed civilian. Meanwhile, the Violence Policy Center has documented over 1,100 killings by concealed carry permit holders since 2007.

Gun carrying also raises the risks of deadly mistakes and confusion in active-shooter incidents. In 2016, an individual shot five Dallas police officers as the officers were providing security at a rally attended by open-carry activists armed with assault weapons. The police chief stated that these activists impeded responding officers, creating confusion as to who the shooter was and whether there were additional shooters.

Currently, 12 states do not require a permit to carry a firearm and about two dozen states require no training in the safe handling and use of firearms.  Even states requiring such training do not approach the standards recommended by experts.  Joseph Vince, a leading national expert,  states that training should include mental preparation, knowledge of the law, judgment, and expertise and familiarity with firearms.  Just a handful of states take training seriously and, under the proposed Concealed Carry Reciprocity Act, they would be forced to allow individuals to bring in guns from states that require no training at all.

With gun violence and mass shootings presenting grave threats to Americans, this bill represents a retreat in standards governing the carrying of guns.  This retreat would ignore the shortcomings of civilian training, as well as polls showing the public’s increasing desire for stricter regulation of firearms.  Congress should reject this bill in favor of one that will actually keep America safe.
