I’m with @Muldermuffin here, as a gun owner who enjoys target shooting, and firmly believes that the owner has the responsibility to have sufficient training and the ability to secure his firearms. Which is why I have a CCW (although I rarely carry after I stopped working a night shift at a local pharmacy) and have taken 2 state approved firearms safety courses, and have a full sized vault style gun safe.
Having said that, I feel that other than the kneejerk reactions to any controls that MM already mentioned, there are several other issues that plague the minds of the hardcore gun enthusiasts. One, whether or not its true about gun grabs, they believe it. Just as with the Rightwinger’s absurd demands and outrages, the most extreme gun grabber dialogues are what get the media attention. Which makes it very easy for those already stuck on a factually deprived Fox News diet to assume everyone else on the left believes the same.
Second, is the financial aspect: let’s say we as a nation had a wake up moment, and passed a Constitutional amendment banning private firearm ownership. And we aren’t going to do the current hodgepodge where pre-existing firearms aren’t grandfathered in. So . . . is the government going to buy back all firearms, ammunition, reloading supplies, etc at fair market value (prior to the ban) to destroy them? Because in a 2018 article for WaPo, they estimated just shy of 400 million firearms are owned in the US. That’s . . . a lot, since even a cheapist gun runs $200+ to $5000 or more at the high end. And then everything else I mentioned. Could it be done? Sure, but it’ll be expensive, and that’s not counting a good faith effort to compensate manufacturers, retailers, sporting goods companies and the like.
So that gets us back to the OPs point of control - not banning, but making sure of the safety of not only the gun owner, but those who the gun owner could put at risk, both by active malice, and passive negligence. And here I think we have a lot of range to work with, but again, we get the horrible squishy people factor. Many gun laws that do pass are based on looking good rather than good arguments. To chose one example, I live in CO (yes, I know people in Boulder, and no, they weren’t hurt thank the FSM), and after the Dark Knight shooting, they passed . . . a magazine limit size. Didn’t deal with pre-existing larger magazines, and they picked 15 rounds. Why 15 . . . well, there was no reason provided. From what I can gather from LEO and security, they weren’t even consulted.
For me, it was a minor issue, since I only had one firearm (a pistol that was 17 rnd standard) in that range, but I still ended up selling it to buy a different one I could replace the mags in. But why 15? Why not 12, or 10, or 20? There isn’t science involved. A similar issue is when people argue about Assault Rifle bans. I don’t own an AR platform, but I do have a lovely blue steel and wood Ruger Ranch 14. It’s a semi-auto in .223/5.56 with a box mag, so functionally the same as an AR, but no one finds it threatening (ok, so it’s not tactikool as some would say, but the point remains).
We need more substance, and more science involved in the mess, and that’s where like MM people like I get hammered. If we talk with our liberal friends about the possibilities of responsible gun ownership, we tend to get yelled at as ‘just as bad as the rest of the gun nuts’. If we talk to fellow shooters, we get (more?) grief that we want a common sense compromise. Thus we often keep our heads down.
Now one thing that is going to be interesting over the next few years is the massive surge in first time gun owners after the protests of the past year and COVID means that for the first time, there is a large number of concerned gun owners that otherwise skew liberal. Is it going to change the overall attitudes? I don’t know.
Lastly, what would I do if I had political influence? Well, I am all for mandatory federal gun registration - I have a detailed list w/serial numbers already on record for my Homeowner’s insurance, because theft’s a more realistic worry to me than a national gun grab. I wouldn’t mind a mandatory 2 hour safety class as a requirement to purchase a new firearm unless you can provide proof of one, or military/LEO background BUT I would require that it be provided frequently and at government expense, as to not provide undue burden on the purchaser - in person would be ideal, but online or pre-recorded instruction with tests would be an easier option. I am also of the opinion that using a firearm during a crime should be a multiplier to sentence - the ease of use and preplanning involved should at least automatically demand the higher levels of any sentencing range at a minimum.
And I strongly feel that it is in no way a burden on a gun owner to own a trigger lock or safe for their firearms for when they are not physically on the body. And that there should be serious legal penalties for an owner whose firearms is used in an shooting without their knowledge - whether it be by their child, friend etc. If you aren’t responsible for pulling the trigger, then you better be ready for a charge of criminal negligence.
Lastly (I know this is a book), I do not have the medical training to pass judgement on where the mental health evaluation threshold should be. I do feel there should be one, and I share MM’s concern that it is ripe for abuse as well, so there should be language in any law where the accusing party in a red-flag situation should be liable for a small/token fine paid to the owner if an evaluation does not bear out. Personally, when I read that the Boulder shooter had a previous conviction for violent assault that was pled down to a misdemeanor, I felt that was a huge miss for the system. But that’s another book.
