I think the fundamental problem is that we’ve got so many guns in circulation that are only known to the government in the most vague aggregate sense.
Any attempt to regulate those is going to either be ignored, or require some level of intrusiveness (registration of ALL guns or something) that is going to be seriously unpopular.
For example regardless of what the laws are, how does the government get a handle on say… me giving/selling my grandfather’s old shotgun from 1958 to my brother? They don’t know it exists, and have no way of knowing that I sold it, or my brother bought it.
Of course, that situation is the ideal one in the sense of we’re both safe, law abiding people who would pass any necessary background check. But the government would have similar difficulty in keeping me from selling it to some low-life out of the trunk of my car for $100.
I feel like market-based solutions won’t work- they would reduce shooting among the people who are safest, and do exactly zilch to stop the loon who saves up thousands to go shoot something up, or for the criminals who steal their guns/ammo in the first place, or steal to buy them.
I wonder if there could be a multipronged approach. Maybe something like enhanced and tightened background checks combined with a fairly lengthy waiting period (like 45 days or something), unless you get some sort of license which has other stipulations- registration of what you buy, periodic background checks, HIPAA clearance for your mental health for license renewal, etc…)
Combine that with serious effort to identify and monitor people who might be at risk for being a mass shooter beforehand- some sort of professional obligation for mental health professionals to report people, maybe some sort of social media style profiling (in fact, make social media platforms do this, since they already have the data and technology) to identify potential shooters and put them on the red flag list for gun purchases.
It seems to me that nearly all these people always seem to have been identified by someone as a potential school shooter or to have something wrong with them ahead of time. Or they buy those guns and go shoot stuff up in a very short time frame. I would suspect that a lengthy enough waiting period combined with better background checks would minimize the mass shootings as much as can be reasonably expected.
I don’t think we’ll ever eliminate them completely- there are too many holes for people to fall through involving existing guns, emergent mental illness, etc… But we could minimize them. if we so chose.
The biggest problem is the slippery slope attitude of the hardcore gun lobby - they won’t negotiate, they won’t come to the table. Any restrictions are off the table for them.
