What rights do we have against 'civil-forfeiture' when pulled over by the police?

It is NOT illegal to carry cash! No matter what questions a police officer may ask, or accuse you, you are 100 % in the right and have to prove nothing to the officer of where it came from. The officer has to prove you got it illegally. I always try to cooperate with the law and be respectful. However, know your rights, and know what you are willing and not willing to accept for questions and searches. Most cops are decent, and there should not be any questions. You can demand that their lieutenant shows to the scene. They are judged by their superiors too.... and get reviewed on their job too...
