How the fuck is a fake ID going to be intercepted in the mail? seriously mail does not just 'go missing', if it was by some astounding unlikely scenario lost by the postal service it will hardly end up in the hands of LE. All this talk of lost shipments are as a general rule not anything to do with the postal service, they are either never sent or in a small number of cases intercepted by customs when crossing international boarders. Are you sure it was sent to the correct address?? Are you SURE it was actually sent? do you have tracking?? If you are using that address for other illegal activity i.e. having drugs sent there then it is conceivable your address has been compromised and anything sent there may (that's a very big may) be being checked. I doubt it was ever sent mate.
