Is it possible that perhaps the FedEx employees may have seen these so called "pill bottles" and were either told 1) they're legal supplements/medications or 2) had no clue what they were when they were observing the operation since they were only interested in the shipping logistics? With just a cursory glance, it seems that it was written up by an overzealous federal prosecutor who wants to make his/her career's achievement busting a big company like FedEx as part of a massive drug ring with conflated charges.
