Prosecutors say they froze 149 bank accounts and detected bank transfers of over $46 million related to the scheme, in which the oil was smuggled across the border in tanker trucks with false import documents.
I guess I should have read the entire article as it seems based upon the above statement that they were clearing legal check points but with false documents... That makes more sense.
You gotta know all those tankers, even with false docs, had help from people who were paid to look the other way. $46 million is a lot of trips.
Seems to me I remember hearing of a scheme a few years ago involving natural gas tankers also.
