BigMike said it well. I feel for you man, it really sucks when you werent TRYING to do wrong, and you did. But I personally have been in trouble before for things that I was truly innocent of, and was found guilty. It just irks me a lil when I see a true guilty person trying to plead innocent. That wastes money in our system, that we all pay for. It is your right as an American citizen though to fight the charges, and if you feel strongly enough that you were not wrong, or not speeding for that matter than by all means, fight the ticket.
