I have had encounters with police a couple times, most very minor with no consequences for me - besides speeding and shit.
1.
My buddy was smokin a blunt while driving, we were all passing it around, cops pulled us over, had all four of us get out. Fortunately for me and the two girls in the back, the car pretty much pulled into our apartment complex. He was arrested, charged with a DUI, car towed.
2.
Got caught smokin in a parked car, they made us brake our pipes, we had like five of them with us, they poured our weed out and smashed it into the pavement - three different strains or so. Then the let us go, prolly figured that was enough punishment.

The WORST - my DUI - really is a SORE subject. I was smoking a lot back then just like now, 1/8 +or- a day. I was on my way work in the morning (like 4:30 am) and couldnt re-up until after work - I was much younger might I add before stating - so I pulled out my piece from under my seat and hit the resin that was under the bowl. I made an illegal left had turn out of a gas station, didnt even see the sign, and was immediately pulled over like I was a kidnapping suspect. He was kind, pulled me out of the car, said it smelled, did the sobriety test, of course I failed, found the piece and took me to the police station - under arrest. On the way there he told me that it sucked because he and his buddies were stoners in college, he just couldnt let me go because there was a story in the paper recently about an officer making a judgement call on a sobriety issue that lead to a fatal accident - the officer was sued. I was booked and let go, $2,500 for fines, another 300 or so in mandatory classes, plus some 2 or 300 for my license.
