I had first hand experinece with this from a good freind of mine that i wathced happen too... What they did is came to the door, it wasnt a postal inspector but it was a dea agent, they handed him the pack, he did NOT sign for it and they pulled out the warrant and came in the house... They found nothing and he beat it badly in court...they would never tell you they are coming back, there probably trying to scare you or something... I highly doubt he would lie about this because it does happen all the time...Deleting the hd will not work, everything on your computer since it was first used can be found deep in the files, every email, every transaction, every thing...if this is true the only way they could prove this without a signature is from your comp, that is almost always the way people get caught and convicted, most people dont know that anything can be found even if it was not saved... i would of had my comp in the fire so fuckin fast they wouldnt of known i had one, fuck i would of smashed it right in front of them, no evidence no case...there are alot of ways of getting caught and the two most common are loose lips and bad packaging...i hope you read legal muscle which i have twice, and hopefully anyone who uses and orders aas does, it will save your ass...big time. dont say nothing, those fuckers are sneaky and tend to get people to rat on themselves or someone else just to get out of it, dont say nothing, the more you say to them the deeper your grave gets, even if its how about the weather, dont talk to those fuckers...
