Your points are quite solid Jeade. Pretty hard to argue. I quess in the US it makes sense to be armed. The problem is that the US got a little too late with disarming its civilian population. And now an entire culture has risen up about prasing firearms and industries making heavy profit. All countries have had a point where their civilians had the right to bear arms, but those laws were retracted once stability was regained. US however never retracted it. And now its too late. So much is in circulation that your criminals will be easly fully armed forever.
That's honestly where I stand: It's too late.
Guns are going to exist in this country whether you like it or not, whether your state likes it or not, or whether the Fed likes it or not.
I will say again that I believe pistols are the real issue here despite scary polymer rifles showing up in the news most, but there are simply way the fuck too many to make them go away.
Besides that, a few others have posted great statistical resources which show how seemingly well and how seemingly poorly gun control works in different countries across the globe.
What needs to be focused on (in my opinion) is mandatory registration (to be used in investigations after a crime), and greater focus on mental health and culture.
I truly don't believe that gun violence is as simple as there being too many guns or too few regulatory checks; I believe it's both, and only one of those options is truly feasible.
