a semi-auto (AR-15 like looking weapon) slung over his shoulders, a handgun in a holster on his waist, and a lump on his right ankle above his boots. And two knives on his belt. Dude looked like he was ready for some urban warfare.

Ironically, the lump might have been what gets him into trouble. If he’s concealing a firearm without a permit, it can land him with some pretty hefty penalties. And if he has a permit but is printing (meaning the concealed weapon is visible through his clothes, like a lump) then it can also land him with some penalties.

It’s dependent on where you were, as each state has their own concealed carry laws. But in general, you’re not allowed to conceal a firearm without a permit. And if you do have a permit, you’re not allowed to have that concealed firearm be visible (even indirectly, like printing.)

Plus if you’re open carrying, Walmart internally bans them anyways. They’re a private business, and have the authority to dictate what people are or are not allowed to do while in their stores. The company has a blanket policy against open carrying, and (assuming they’re not barred from doing so by state law) the dude should have been told to leave his guns outside (like in his car) or be trespassed.
