If they want you, they will get you. Doesn't matter what you do or say.
All these three instances have happened to me:
1. Package gets intercepted by customs. They wait 4 weeks for the lab results to come in to confirm indeed it's something illegal. Package was addressed to a fictitious name, to a PO Box. I (real name) was the owner of the box.
They get a search warrant and kncok on my door at 7am - feds and customs officials. I never saw the package never mind accepted it. My house was raided.
There was 500 d-bol in it.
2. Package gets intercepted by customs. It's addressed to a fictitious name to a PO Box owned by a friend. He just moved. Using the info of the box's owner, customs/feds stake out his house (that he just moved out of). One day he goes by there (empty house) to get his mail. They follow him. As it happened, he came to my house after that. They recognise my house, and they get a warrant on it. I get raided again. This was over $160 worth of gear.
3. 10,000+ naps get mailed to an address on the other side of the city, 50 miles away. Not my name at all. Not my address either.
Customs and feds raid my house. When I asked the head inspector why, he said 'It was a package from Romania of steroids. Your Romanian and a pro bodybuilder. As soon as the paperwork came accross my desk, I knew you had to be involved'. When my girl said - 'So you are here because he is romanian?' He said 'Yes'.
In all three instances the warrant was performed on the HOUSE, not on any person. That way, they can search the entire house, regardless of who owns it or who lives inside it.
Customs and postal officers have at their disposal anything they choose, including assault teams supplied by the feds, immediate warrants, etc. While the feds do pretty much everything by the book, customs and postal inspectors don't because they can get away with A LOT more than the feds, and they are the ones doing the inevstigations. Once they did their part, then they give your case to the feds. And that's when you get away with things if they did things wrong, the way they did with me. But until then, they will turn your life upside down.
