What I'm saying is don't bother going to court when you know you are guilty. Did he or did he not, even in his own estimation, exceed the speed limit by an amount that virtually any officer would issue a citation for? The answer is yes. Only a dick would attempt to get off on a technicality in this case.
I wouldn't go as far as saying don't bother going to court - you usually have a good shot at being able to plead guilty to a lower or even suspended penalty. It's almost always in your benefit to at least show up and talk to the prosecutor.
But trying to weasel out on crazy technicalities is a good way to get the book thrown at you. Remember that traffic court judges sit in traffic court all day every day. These "defenses" will not be novel or convincing to them. They will probably find it annoying and insulting, which does not work in your favor.
