Of course this is all academic as when it comes to going to court to fight what you think is wrong, the judge will believe the officer over you in most cases. Doesn't make any difference at all unless the judge gets inundated with people going to court from the same officer on the same day with all of them complaining about the tickets. Your friend doesn't have a chance in not making the ticket stick. Been there, done that, got the t-shirt and the ticket.
