No. There's only one issue. In the United States, it is absurdly easy to obtain firearms legally or illegally, and to also obtain mechanisms that increase a firearm's lethality legally or illegally. We are willing to place limits around every right we have from buying fertilizer in bulk to not wearing our shoes across a dirty airport floor to hollering "fire" in a crowded theater - except one. A right that is linked to militia service which 99% of civilian firearms holders will never see. Written with an eye to 18th century weaponry - hardly AR-15s and semi-automatic handguns subsequently made automatic.
As Bishop Dan Edwards stated, as Americans we have no constitutional right to food or medical care but we are fanatically jealous of our capacity to kill, because this is what makes us matter. I can kill, therefore I am.
Not a flattering opinion of Americans, but I believe he is correct. There is no other reason for us to hang on to pieces of metal that have one reason for existence - death. When poll after poll from multiple polling organizations across the political spectrum reveal that Americans want at least small changes to gun laws - the ability to stop people with psychiatric diagnoses from getting guns, closing the internet and guns show loopholes, make gun laws standard across the country because this patchwork method doesn't work - Congress won't act because the NRA opposes even these small compromises. Americans understand it won't stop all tragedies, but it can't hurt.
I know that if 20 first graders being executed in cold blood in their classrooms doesn't change anything, the chances of Las Vegas making a difference are slim. There seems to be unlimited "thoughts and prayers" out there and precious little stomach for taking the hard stance that might make some small difference. Somehow or another I don't think our deified founding fathers - who are always pulled out and dusted off when the second amendment is challenged - quite envisioned dead children or concert goers being picked off like fish in a barrel in their "intentions" in composing the Bill of Rights in 1789.
