I am no expert on legal matters, but I have been thinking about this question for a good while. I honestly don't see how LE of any kind could expect parcel services to deny shipment of certain items, as there is no way to know what is in a package without opening it. I could understand them denying shipment by certain companies they deem to be engaging in illegal activity, but if that were the case then they should shut them down rather than limit them. IMO the same general rule would apply to credit card companies (with IOPs being the possible exception). Again, I am no expert, and this is only my take on it...but we DO have a few examples of exceptional legal knowledge and understanding on this board, and I would definitely look forward to reading their opinions. Thanks in advance.
