people send shit in the mail all the time, you think cops have nothing better to do than try to entrap people opening their mail? I open mail from people (Companies) I don't know every day, if there was something in it you ALWAYS have plausible deniability. No way a cop or Fed is going to try and get a case where it is as easy as can be to go to trial and have no conviction. Cops like a sure thing. Have it sent to your address but not in your name, it will still deliver. Plausible Deniability.
