An interesting read
However, I cannot understand that someone agrees to move product without being able to inspect it in any way and not know that they are part of something shady. If it's legal, it is transparent, and I have the duty to ensure that the product is in good shape and has not degraded in any way, or does not risk degrading.
To do my duty, I am responsible for the product while it is in my care and I must be able to have eyes on it. If that is not part of the deal, then I am not going to take part.
