another trick is mail an unsealed envelope to yourself (with somebody else as a return adress) and keep ur stash in it. if u get pulled over, or the cops come in your house, lick and seal the envelope. they cant open your mail, and they cant make you open it.

this is what ive heard anyway.

the way to copywright music in canada is to mail it to yourself, then if you are ever in a dispute, you open it in court (the mail has a date stamp) and you can prove on what date you wrote the song. so if the mail was part of your copywrighting, the cop would ruin your copywright by opening it. i think thats part of why mail is safe.
