In the mid 90’s I remember a short article in the Oakland Tribune where a customs spot check on some cargo in the port of Oakland turned up 2 cases of AK-47’s, full-auto and no serial numbers. Point of origin, China. The article was just a short paragraph then it disappeared down the memory hole.
Clinton had signed the assault weapon ban, but had given a waver to the Chinese to ship in, IIRC, 100,000 to 150,000 SKS rifles. They were so cheap you could buy one for under $50.
They were smuggling in the full auto weapons with the SKS’s.
They said they found enough weapons to supply a small army.
How many were shipped in before they got caught nobody knows.
