Wait, what chaos are you referring to? I'm simply stating that the right to bear arms is enshrined in the US Constitution and it's wrong that the Sheriff is acting as some kind of gatekeeper on who should be allowed to exercise their rights, beyond what is codified in law. That's all I'm really pointing out here, in line with the article posted here.
Frankly, we could definitely go into comparing other countries and how they handle this compared to the US, but this is an entirely different can of worms I can't really do justice here in an HN comments section.
I may suggest checking out /r/gunpolitics on reddit, or if you're aligned with liberal or leftist ideology, I strongly recommend /r/liberalgunowners and /r/SocialistRA for more information. I frequent those spaces often.
Finally, for all the news does to point out violent crimes committed with firearms, there are numerous defensive uses of guns that occur nearly every single day that slip under the radar. /r/dgu on reddit can show you some examples there.
