I have to admit that I find it difficult to believe that you could be charged with a misdemeanor offense, tried and convicted without any proof whatsoever of speed, etc., especially since the burden of proof is higher in a criminal prosecution as compared to an administrative hearing for a simple moving "violation."
Granted, speed traps and similar tactics are used often by local police authorities but somehow there seems to be something missing from your version. I am not suggesting that you make any factual statements in this forum at this time, rather my free legal advice would be to stop writing anything here because all your statements may be construed as admissions against interest in any criminal prosecutions, including at the appellate level.
That being said, although I am sympathetic to your situation, it would be helpful when this is over to provide details as to the charges and the defenses to avoid causing undue concern to other members about their canyon drives, convoys, etc.
For example, you mentioned that there was a charge of doing twice the speed limit in a school zone. I don't want to get preachy but as much as all of us enjoy driving our cars the way they were designed to be driven, it doesn't benefit the NSX community to be perceived as "reckless drivers" by violating school zone limits and then expecting everyone to feel sorry if you get caught.
You may very well have been "set up" and have a valid defense, either at the trial level or on appeal. However, I just felt it necessary to voice my opinion that something else must have occurred for you to be in your current predicament rather than a complete fabrication of events by an over-zealous police department.
I still wish you luck with your legal battles but at the conclusion of them it would be beneficial to all on this forum to understand all of the facts and allegations, along with the proof presented by the prosecution that led to a criminal conviction, to be able to better protect against a similar occurrence to another member.
