OH Speeding Ticket controversy for me!!!

[Scav]

So driving to work this morning and for those that know Higgins Road in Schaumburg, there is a stretch through some woods where you go pretty fast. I got pulled over by a sheriff saying I was going 64 in a 45. Now, I would almost guarantee I was probably going faster then that, but the guy was like "I have to give you a ticket but I will give you a court diversion slip" So I automatically am thinking that he doesn't want to go to court. When he comes back with the ticket, I ask "Can I please see the radar gun" he says "It is already cleared". I say "Ok" and that is that. Now, there is NO WAY that he got me on the gun given he was going the other way down Higgins, and there is no way that he could have paced me because he was going the other way?

Anyone know if there is a protocol in radar gun clearing? I am going to contest it and go to court, not only will he probably not show up, but after that I think I have a decent case.
