i'm not sure if this has been said, considering I get tired of reading sometimes, and need to post what I think before I forget it. I have seen people refuse a search of their car so the cops proceeded to place them under arrest for one charge or another and than search the car. It all depends on if the cop is corrupt or not and how he feels about such substances. But denying a search doesn't always mean they won't find another reason to search your car. It's fucked up but it happens.
