I don't think anything will change people's minds on this. I don't agree politically with the NRA. But if we are honest there are more than a few people on the gun control side who really would like to limit just about all weapons to police and military. I'm not in favor of that. The NYT had an editorial yesterday that talked about the "scourge" of concealed weapons. The NYT thought that "shall issue" permits were a bad idea and that the states should be forced by the federal government to rescind such laws.

Now whatever you may think of such laws, they have not in fact, caused increases in shootouts. The people who go to the trouble of taking the class and getting the permit generally speaking are not the people causing carnage. There won't be "reasonable" gun control discussion because people on both sides see a slippery slope.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
