i recieved a 5th degree cpm the the other day while smoking weed in a car on a dead end. we started to drive away when we saw a cop coming down the road, and he turned around and pulled us over. from there, he took the drivers license and registration, and than made me open the back door of the car to search for "spry paint" and said he smelled the weed. we had put it in the trunk and he found 2 bongs, a grinder and no more than two grams of weed. i was never read my rights, and he never gave reason for pulling us over. is there any chance i could get out of it due to illegally obtained evidence?
