About two weeks ago, i got pulled over for chirping my tires, the cop that pulled me over was a really cool guy and gave me a written warning for that, but he gave me a ticket for not presenting my registration at the time i was pulled over. I told him "I think this is my old one" and handed him the "older" registration, only to find out today, the same day i go to get my new registration, that the one i handed him was infact valid. Is there a way to fight this in court? Is there a way to prove that i did give him the current one? Its not a huge deal to me, but everyone likes saving money. Any help?
