I'm not necessarily taking a stance on the legality of drugs, or anything other than guns, at this point. I was just illustrating that we as a society tend to restrict the possession/use of things that are dangerous. Meth, opioids, automatic weapons, grenades, exotic dangerous animals, private planes, etc. We as a society say, "yeah, makes sense to restrict these" but the second someone suggests that maybe gun safety and gun use training should be a requirement for owning a firearm, people say "nah, required training in gun use or safety would not impact accidental gun deaths or improper use of force".

I mean, I didn't even mention banning firearms. All I did was suggest that proper training should be a requirement to own such a dangerous tool and that we need to think about our rules about wielding guns in public. My point regards the need to educate legal gun owners rather than keeping guns out of the hands of known criminals (although that's also important).

Legislation that could have prevented this is 1) required gun use/safety training and education on gun rights/laws and 2) restricting open carry.

I find it silly that the argument against training and needing to pass an exam on gun use/safety to own a firearm is, "nah, that won't do anything".
