After the Las Vegas shooting, in which 58 people were massacred and hundreds more injured, lawsuits were filed against the companies that organized the concert, own the hotel and made and sold the bump stock device the killer used to increase the firing rate of his weapons — everyone but the companies that made and sold his guns. That is because the gun manufacturers and sellers have a weapon that is not available to the concert organizers and hotel owner — statutory immunity.

The N.R.A. claims that the act is necessary to protect gun manufacturers and sellers against unfounded lawsuits. Unlike cars, hammers, tobacco and alcohol, its argument goes, guns are intended to kill. But our legal system has multiple checks to filter out lawsuits that lack merit. There is no reason for the gun industry to have special protections that are unavailable to other businesses that sell products that pose far less risk of harm.

One element of the N.R.A.’s argument is true: Guns are inherently dangerous. But there are proven ways to make them safer. One study found that more than 40 percent of accidental gun deaths could have been avoided if the gun was equipped with at least one safety feature. Because of the act, gun manufacturers have no incentive to include such features.
