I would have appealed that for the rest of my life.
My word against his, and to put it in the words of several judges over the years: "It is your word against the word of a police officer, and I have no reason to believe that the officer is lying." The cop broke the law; you can't pull somebody over simply because you'd like to check out the car. Proving that is another thing altogether. I have never seen a police officer tell the truth in a court of law. My word against his, and the judge has already made a decision on whose word he trusts more.
