Sounds like someone wanted to test the limits of Missouri's open carry laws.
Probably not the best time to be doing that... what a dumbass...
How friggin stupid do these people have to be to not realize there will be panic when someone walks into a Walmart like that? Legal open carry of automatic weapons in a public business has to be one of the stupidest things I have ever heard of. Why? Because no one will ever know. And what if everyone went in there with automatic weapons? They still wouldn't know who to shoot or not to shoot if someone started shooting, because every one would be with guns. Have we lost our ******* minds?
We see people with guns here all the time. No freak, no panic. I carry sometimes and James carries all the time with zero problems. Including at walmart.
This guy is an asshole. A law abiding asshole, but an asshole anyway. I've seen videos of people that do this kind of thing before. Waking down the street with big skeery guns. Some want to show off their ass and have something to brag or giggle about with their friends. Some just dream of becoming internet famous. Some enjoy tweaking peoples noses, citizens and LE alike.
Who knows why assholes commit assholio acts?
And if everyone went in with automatic weapons, there would likely be no shooting at all. Remember MAD we had going on with Russia? Mutually Assured Destruction, wasn't it?
And it worked.
