> sell guns in supermarkets with next to no checks on who owns them
Yea, A, you might be able to get a single shot hunting rifle in a walmart in a rural part of the USA... but it may not work to begin with because it's a cheap piece of crap. You're really not going to buy some eggs, milk, loaf of bread and an AK in the same store in the USA. Stop believing bullshit.
B, Neil Steinberg for the Chicago Sun Times believed the same thing of "no checks". He got denied a gun because he got picked up for beating his wife a few years prior. Then blamed the store for the deny. Which, a gun store clerk/owner is in full legal right to deny service to anyone, even if the customer qualifies. The DEA encourages them to deny and report people if they feel the customer is purchasing a gun for malice... except, Neil beat his wife after drinking too much booze. So the DEA denied him on that one. Lots of people think they can get easily approved for a gun and realize real quick they can't. I've been in gun stores plenty of times to see people apply, wait and get denied.
Just like in countries where guns are illegal, you can buy guns on the black market.
If you actually know cops in the USA, they generally like those with conceal permit licenses. It means they're not prior felons, they don't want to lose their gun or the license, thus don't want to do anything stupid. There are exceptions, just like with anything else. "Sovereign citizens" are a special class of complete stupid. But a majority of legal gun owners have zero interest in doing anything stupid. I already know all of this is unpopular opinion and I'll get lambasted by non-gun owners. Whatever.
