Do you find anything wrong with this ticket for 'running a red light'?

About a month ago, my brother (who’s 21) and his friend and girlfriend were driving at 1:30 AM to the 24 hour Wal-Mart to pick up a movie. On the way there, he was pulled over for running a red light. Only thing is, he didn’t run the red light! (I know he isn’t lying because he’s horrible at lying). The officer made them get out of the car and searched it and even searched his girlfriend’s purse! There wasn’t any reason to be searching the car in the first place. The officer didn’t find anything and ended up giving him a ticket for running the red light (which, remember, he didn’t do). On the day of the court date, his witness doesn’t show up because he slept in (some friend, I know) and his girlfriend had her hands tied in something else. He ends up pleading guilty because he knew that the judge would side with the officer (He has had something similar happen before and understood that arguing would get him nowhere). The judge fines him 30 dollars. He was fine with that. Now, today in the mail, he got a letter from the court stating that he owes 90 dollars for this incident (Which he never did…just reiterating). The extra 60 dollars is because of court fees. So, do you think this is fair? He’s being charged 90 dollars for a crime he didn’t do in the first place, while he was under the impression he would be charged 30? Do you think anything about this is fair?
