I dont know about many other states but from what I learned and hear, In wisconsin If a cop wants to search your vehical when he pulls you over he isnt going to need probable cause. When It all comes down to it probable cause can be the officer saying he smelt something and then search. Its his word against yours fighting in court and guess what you were busted when he searched you with possession so you are guilty in the courts eyes. Ive been with friends and we were not high and a cop pulled us over for a broken light. Nothing insight, No smell, and no one has records. The fuckin pigs pulled us out not telling us why and 'decided' to search the car finding 1 GRAM on the floor. I forgot to add I hate fuckin pigs. Donut eating porky the pig white and blue Ill pull a gun on you I got lil sirens to play with cause Im a fuckn super hero saving the comunity and when I go home at night I smoke highschoolers weed I confensated and so I eat more donuts 10-4 I cant fit out my driver side door My canine unit is looking at my chunk like its lunch.
