I was in WM last evening to pick up a few things. One of the things I bought was a plastic ammo box, 50 rounds, med rifle. (Have to start loading up some more 600 yd ammo) When I went through the self-checkout line, the ammo box was the first thing I scanned. It beeped and said I needed appoval to proceed. The girl came up and approved it and it didn't bug me about the IMR 4064 or the PowderBlast I also bought. I just thought it was funny in a ridiculous sort of way that buying a plactic box required approval at checkout.
What is Walmart's reasoning behind this? Would selling me the ammo box make them complicit if I filled that box with ammo and took it with me on a killing rampage?
