Here's another point of interest not stated. HAVE YOUR DRIVERS LICENSE ALWAYS. Although you may not think it, cops in most states have the right to arrest you On The Spot for not having a license. I mean immediately step out of the car, no questions, handcuffed, your car is then searched, whether or not you consent. If they find a pipe, they'll call it warm whether or not it was and you bet your Ass your going to jail for a DUI, no field sobriety tests or anything. Simple as that, they do what they want and make up reasons for it. Also, NEVER ADMIT TO ANYTHING, you may think it will just piss the cop off, and if you admit yeah man I was tokin he may just let you off, HA! They have microphones for a reason, assume the cop is Not going to cut you a break. Like the adam and whatshisface video linked, assume the cops cannot relate at all to being human. If your car smells and you have to crack the window and the cop asks you why... well your windows broken. He wont figure out that its not if you have your license, dont consent, play it cool. I disagree with the cigarette part, light that sunabitch as soon as he pulls behind you. You can say your a chain smoker, it may keep him from smelling the stuff in the first place, and if he smells something it will give you a point to argue in court. No sir your honor, not pot, just clove cigarettes.
