They are pulling them to keep them from the looters.
Yup. Wise move, actually. For decades, most of us have been stocking ammo for a wide variety of rifles, pistols, and shotguns.
They're being disingenuous. They're pulling a lot more than firearms, especially pharmaceuticals but they don't want to be called racist by announcing it.
They know exactly which stores already have high "shrink" from items being stolen. It's tracked by each inventory adjustment and Loss Prevention rolls it up weekly.
Cheat looting blacks of their rights to have guns????????
