The simple fact is that there are probably at least 1/2 billion guns in this country, and more are being bought every day. They are NOT going away, no matter how much in the way of registration schemes and effective bans the hoplophobes enact and try to enforce. This is particularly true with CAD/CAM and 3-D printing really coming into their own for individuals, even those with few of the traditional skills of metal workers.
As such, the best that society can do is to allow good and decent people to protect themselves from your common street criminal, and also the mentally-deficient who try (and often succeed) in carrying out a mass murder. It’d be nice if those taking psychotropic drugs, or those who clearly need them and who aren’t doing so, were reported by family members to medical and law-enforcement authorities for a quick examination/evaluation (without guns being seized), but that isn’t going to be effective over the long-run - people don’t take such reports seriously, and there are just too many of them. Perhaps another solution is to require every person taking psychotropic drugs to be examined by a psychiatrist every week or two, on the chance that they are the one in 100,000 or 1 in 1,000,000 who are made more violent by these drugs.
But truly the only solution is to not restrict the rights of innocent citizens to own firearms for their protection and that of their liberties. That’s what the 2nd Amendment is about (the latter, actually - defense against street criminals is a fringe benefit), and if we actually lived it across the country there would be a vast reduction in crime after an initial spurt when a lot of criminals would be given a dirt nap.
Guns aren’t going away, and the antis had better get used to that fact.
Oh, and I’m VERY glad to be living in Texas, rather than the dark and fascist Peoples Republik of New Jersey where I grew up. People in government are sane regarding firearms. You can even carry in the Statehouse!
