Godfather........I think you're missing something here, if a postal worker opens one of "our" packages, that's the best thing that can happen (besides us actually receiving the package of course)
Cause if a postal worker opens up a package and finds a bunch of juice, nothing more can be done. The "evidence" so to speak has been compromised by "non law enforcement". Think about it........after a postal worker has opened a package he can claim finding just about anything. So can any customs agent for that matter.........but customs agents, because they're federal law enforcement, are automatically regarded as NEVER lying. There's way too much gray area regarding a regular postal worker opening a package. If they discover gear they'll probably either throw it away or turn it over to the authorities.....who will than pretty much have to throw it away themselves, although they might put your address in their files for future reference.
