In his Sept. 27 Book World review, “A moderate gun guy exasperated with radical rhetoric of fellow owners,” Michael S. Rosenwald shattered the notion that the gun lobby is focused on the interests of gun owners, highlighting how organizations such as the National Rifle Association take positions contrary to those of the majority of their members.

To end gun violence, we should find ways to keep guns out of the hands of dangerous people, including convicted felons, domestic abusers and the dangerously mentally ill. One simple solution: Expand background checks to all gun sales.

The Brady Handgun Violence Prevention Act , which requires background checks at licensed dealers, was passed before gun shows became big business and before the Internet was widely accessible. Prohibited purchasers use these gun shows and online marketplaces to get their guns, no questions asked and no background checks required.

As the review noted, expanded background checks are supported by the vast majority of Americans, including almost 90 percent of gun owners. Who could possibly be against solutions that save lives without curtailing Second Amendment rights? Enter the corporate gun lobby, ardent protector of profits and prohibited purchasers.

Mr. Rosenwald correctly called out the gun lobby’s unwillingness to listen to the American people and the very constituency it claims to represent. If the gun lobby isn’t interested in a safer United States and what its own members have to say, whom is it — and the politicians who do its bidding — really looking out for?

I enjoyed reading Michael S. Rosenwald’s review of A.J. Somerset’s book “Arms.” Mr. Rosenwald and Mr. Somerset are right to skewer the National Rifle Association for its extreme opposition to reasonable gun-control measures. As a gun owner and hunter, I am offended when the NRA unfurls banners at gun shows proclaiming its support of hunters.  As Steve Jarding and Dave “Mudcat” Saunders pointed out in their book, “Foxes in the Henhouse,” NRA-backed Republican politicians generally have the worst records on the issue that is most pressing for hunters: declining wildlife habitats. 

The notion that the NRA supports hunters is laughable. Declining wildlife habitats, not mainstream gun-control proposals, are the biggest threat to hunters.
