You should cooperate with what they order you to do, and you should always be friendly, but never let them search your property without a warrant or probable cause, as they could plant evidence. If you get arrested, comply with all actions they tell you to do, but don’t say a single fucking word. On the street, try to stay alive, but once arrested, don’t waive your 5th amendment rights. Being a good little citizen will doom you in interviews, and it should never be done.
