The Dayton and El Paso shootings have spurred familiar calls for more gun control, and by all means let’s have a debate. But the focus should be on denying weapons to the potential killers rather than on gun laws that may be politically satisfying but won’t make much difference.
Start with the calls for more “background checks,” which implies none now exist. Yet nearly all gun purchasers today have their backgrounds checked on the spot via the National Instant Criminal Background Check System (NICS). Most mass shooters obtained their guns through licensed dealers after checks, or from family members. The Dayton and El Paso killers, and the Gilroy, Calif., shooter of late July obtained their firearms legally.
Democrats want to expand background checks to person-to-person sales, though policing that would be a challenge as most such sales could be done off the books. They also want to extend to 10 days from three the amount of time dealers must wait to get a response from the background check system before proceeding with a sale. Senators Pat Toomey (R., Pa.) and Joe Manchin (D., W.Va.) want background checks to cover unlicensed sales at gun shows and online, but exempt sales between friends and family.
Congress should have that debate, but no one should think they would reduce the number of mass shootings. Most mass shooters don’t have a criminal history that would pop up in the background system. There is also no evidence that longer waiting periods reduce suicides, homicides or mass shootings. Determined killers can always get a weapon.
