OK so the other night i was with my friends and thier cars and we were just chilling in this gas station not doing anything just talking and stuff. Then like 6 cops rolled up and told us all to get our license, registration and insurance out and put it on the windshield. Then they said to pop our hoods. They went one by one giving everyong tickets for their intakes and exhaust. Even tho they had the carb stickers and stamps on the stuff. Can cops just force you to pop your hood and do that?
