More idiotic blather based on your complete lack of knowledge.
The FBI estimates that only 10% of guns used for crimes are legally obtained, so stopping the illegal unregulated gun trade should stop arming 90% of viloent criminals. Stopping the flow of 90% of guns used for crime is nothing? Derp.

Sure, keeping criminals in prison longer might help some after the fact, but 1) they have to commit at least one violent gun crime first and 2) our prisons are already so bursting full of them… so much that many states cannot put non violent criminals in prison without first releasing violent criminals, so longer sentences are impossible.
BTW- speaking of harsher sentences, a Vietnamese businesswoman was just sentenced to death for a fraud scheme extremely similar to Trumps real estate/bank/tax fraud scheme. https://www.npr.org/2024/04/12/1244509024/a-woman-has-received-a-death-sentence-in-the-largest-fraud-trial-in-vietnams-his#:~:text=The%20largest%20fra

Is that what you suggest, harsher sentencing all around, or only for crimes you wrongly believe are committed mostly by minorities?

This won’t stop every illegal gun sale, but it closes 3 major methods of easily “legally” selling unregistered guns to people who are barred from owning guns. That is a good thing to anyone who isn’t a criminal looking to buy a gun for crimes….and braying morons.

If it does nothing, why has the right been fighting tooth and nail to keep the loopholes open for so long? A: because so many are felons (just like their leadership) and they still want to buy more guns.

Private background checks is full of privacy, communication, and liability issues, true, but that could be solved in various ways.
In gun store private sales, that's how California does it.
Does it stop all criminal sales? Clearly not. Does it minimize them and hold illegal sellers who ignore the law accountable for what others do with the guns they illegally sold, making illegally selling a criminal your gun insane? Yes.
If it was the law nation wide, would it severely curtail the illicit gun trade, and have a positive impact on gun crime rates? Absolutely, zero question.
Would it stop it altogether? Duh, no, no law is a panacea, the death penalty doesn't stop all murders, but it definitely stops most. That is not how law works. No law has EVER stopped the crimes they regulate altogether except those that legalize the crime out of existence....like legal marijuana eradicated illegal pot smokers completely.

[IMDB]"The larger scope of the story explores the gun trade to Africa that takes place under the covers -- Russian pilots fly guns into Africa, then fly fish back out to Europe. The hazards and consequences of this trade are explored, including the pan-African violence propagated by constant flow of weapons into the continent. If it is a "survival of the fittest" world, as Darwin concluded, then the capitalist interests that fund the gun runners are climbing the evolutionary ladder on the backs of the Africans in this stark Darwinian example. Much like the foreseeable extinction of the Lake Victoria perch, and death of Lake Victoria itself, the Africans are in grave jeopardy, even as they survive in the only ways they know how.

In the 1950s or 1960s, the Nile perch was released into the Lake Victoria. In just a few decades, the large, voracious predator has all but eliminated the other species of fish, turning the lake into an ecological wasteland. "But economically, it's good" -- and indeed, perch fillet is Tanzania's best selling export to Europe. Fishermen, factory workers, civil servants, pilots of cargo aircrafts, delegates of the European Commission, communities living around Lake Victoria: plenty of people are involved in some way in this new industry. But if Africa exports hundreds of tons of premium-priced fish each day, what exactly do Africans get in return? Written by Eduardo Casais {casaise@acm.org} "
