I’m no expert on the US Constitution, but I was under the impression that the second amendment basically lets you have guns (well, something something well regulated militia, but that part is universally ignored by now). It doesn’t say you’re allowed to carry in public. I know states already get to set carry laws, which is why some states are open vs concealed carry. I don’t see how this is much different. It’s not like they’re even saying you can’t have guns at your home.
