If you background check (really)
So long as you don't do them unfairly.
If you audit dealers (really)
How much diversion is there, though?
If you register and insure
The gun-banners holy grail--a list of guns. Gun registration does nothing else, none of the techniques for fingerprinting a gun actually work very well. Yes, the cops can match a
recent bullet to a gun--but not an old bullet. Having a catalog of reference bullets from the time of purchase won't do much if the gun is actually used. It would be like taking tire impressions when you buy a car to match tread patterns at the scene of an accident. Microstamping likewise has big wear issues--and is completely useless if the casings are recovered.
And insurance is a
big problem here.
Insurance normally does not apply to deliberate criminal acts and most misuse of guns falls into this category. Only accidents matter--and those are generally to family members. Either they won't be covered or you set up a system that's asking for "accidents".
Insurance is simply an attempt to make guns too expensive to own. The actual harm from guns comes mostly from those who won't be insured anyway.
If you have VERY HGH penalties for unregistered uninsured,
Which is of little deterrence to felons--they're be in jail for quite a while anyway.
If you have annual audits of owners - can start with self-audits
If you follow those reports up with consequences for a stolen gun being unreported...
The biggest vector is stolen guns.
If you ban the rapid-fire weapons and the large clips,
Learn what you're talking about!!
Most weapons out there have the same "rapid-fire" firing rate. Revolvers and semi-auto are limited by the human, not by the gun.
If you do all of these things,
You will have gone a long way towards disarming the law abiding. You will have done very little towards disarming the criminals.
Both the mass shootings and the constant crime-world shootings will be reduced to the benefit of us all.
Mass shootings are particularly talked about because the high capacity magazines involved would be so easy to start with, and because people selfishly tend to focus on the crimes that might hit them - public places, people who are considered “innocent”.
You will reduce the mass shootings, but you will increase the one-at-a-time criminal deaths by more than you reduced the mass shootings. You'll feel better but you'll be less safe.
You left out one very important point; if you did all of these things, it wouldn't affect responsible gun owners one fucking bit. Just in case someone wants to chime in with the "regulation only punishes the good guys" bullshit.
Just about everything on this list is aimed at the law abiding and will have little effect on criminals. It's about getting guns out of society, not about disarming criminals. Calling this bullshit doesn't make it so.
