I absolutely have reasoning, it is mostly common sense.... why do I support background checks? Because it helps ensure that responsible people are buying guns. Why do I support regulations on weapons capable of mass destruction like autos? Because it decreases the damage they can do should somebody use them against a crowd. Why would I support registration? Because it would help law enforcement and accountability when guns are used in crimes.
Do I think these ideas will end all gun crime? Hell no. I realize that there is a black market and many people get guns outside of the law. That’s a separate problem.
Not that I think your intent is anything less than noble, It's simply Naive.
When I asked what your proposal accomplished, I knew the answer already. By the very nature of Gun Violence and Suicide (the majority of gun related deaths), your proposals would accomplish little or none, or even worse, increase the body count, not because the proposals are not noble, but human nature and the criminal mind make them invalid.
One, they are reliant on Criminals to abide by them. Homicide in this nation resides mostly within a small group of individuals that don't really care if you do background checks. Yes, they would insure that Law Abiding Citizens would be limited to gun ownership, but we really aren't all that concerned if a law abiding citizen has a gun or not, they, by default obey all laws, including murder or rape.
A criminal however, would, by default, not apply for a permit, making a background check useless.
A suicidal individual likely already owns a gun, or might not have anything in his medical history that would be caught in a background check that stops him from purchase. Even if he did, someone in that state of mind probably doesn't care. There are many other ways to commit suicide minus a gun. Guns are not a prerequisite to suicide.
I've offered three examples, actual events, in which someone who was suicidal, without access to a gun, used other methods to end their life's. Those efforts didn't conclude with the death of 3 people (actually one lived), but included 9 others. One jumped from an overpass, killing not just himself, but the driver of a car below. The other two involved driving the wrong way down a Freeway, one took the life of another driver and the other taking the live's of 7 other people.
Not to sound morbid or heartless, but if those three suicides had had access to a gun, we would have 3 dead, not 11. So you could see an increase in body count, not a reduction.
Bump stocks, or other devices that makes a semi-auto fire more rapidly, have been used in exactly one mass casualty event. There is no evidence that this multi-millionaire was reliant on the availability of what you propose to ban. As been highlighted before, a man of that means has multiple ways of creating one, should bans be universally placed, or by simply using string in place of a manufactured bump stock. Lastly, we can all be very glad that not many of great wealth end up being murderous monsters. With great wealth comes great ability. What this idiot did was likely minute in comparison to what he could have done had he not had a gun available. Look at what Timothy McVeigh was able to accomplish with limited funds and multiply that many times.
Last is accidental gun discharge. I can't find one in which a background check, registration or banning bump stocks changed what happened.
The answers to eliminating these deaths are pretty clear.
1. Extreme prison sentences for violent criminals. I've heard 30 years, which I am OK with, but longer would not hurt my feelings.
2. Treat Gang Membership as we do Terrorist membership. It is, after-all, what they are.
3. Drug dealers caught with a weapon should be put away as per #1
4. Strictly monitor anyone and everyone put on a SSRI antidepressant and make frivolous prescribing of these a criminal offense.
