In countries where the incrimination standard is reasonable doubt, that you received a package addressed to you is not really a slam dunk proof that you ordered the contents.

Furthermore, in countries where you enjoy a right to refuse to say anything that may incriminate you, you may simply refuse to explain how or why the package was sent to you. The prosecution will need to positively prove that you ordered it, which is a much harder task if the seller doesn't cooperate.

(IANAL, TINLA).

Nobody will ever be convicted for some package, so much is clear. But thats not the point. That package is enough to get a judge to sign off on a search warrant. And in my country, there is no "fruit of the poisonous tree" principle - even if the search is found to be unlawful afterwards, the majority of findings are admissible.

I touched on this in some other replies, but basically, I use my real name/address, try to use domestic sellers as much as possible, and have never lost a package to USPS/customs.

I assume some people rent a postal box under a fake ID.
