Dear JACUSTOMER - All you can do is file an appeal with the court of appeals. It is very difficult to win a case in traffic court since the judges simply "rubber stamp" whatever the cops say. If you appeal you will have to find some issue of law since you can't appeal what the trier of fact (judge or jury) decided to believe.
I certainly understand your frustration but this is so typical of traffic courts everywhere. There are few judges who will actually stand up to the cops and listen to the defendants. Most of the time it is simply going through the motions and finding everyone guilty. Remember, the state or city get paid if you are found not guilty!
An appeal will likely require you to have an attorney and the chances of success are slim. You're probably wasting your time and money to take this any further but that is your right under the law.
Of course they don't get paid if you don't have to pay a fine. I'm not talking about their salaries only the fact they can't collect the fine for their coffers.
