Frankly even if the bans did work, people wouldn’t want them. The US does not care about gun violence because the people in power are pandering most to people unaffected by it since they’re who vote in the primaries. The US cannot and will not address its gun violence in the near future and it will not address the fundamental needs of its people if conservative leaders continue to get elected.
Basically, the US is probably screwed and is due for increased violence one way or another. Especially since we’re all allowed to own a deadly weapon and yet a good portion of us aren’t even literate.
