Well, that was the explanation I got, without going into too much detail. Curiosity did get the better of me, so I called the office and asked for more information, and they won't tell me, which was... interesting to say the least. The reasoning I got is because they don't want to give out the information "publicly" on how to fight a speeding ticket. Yeah, your initial response to reading that is my initial response. The lady did tell me the motion to suppress is usually the speed camera/RADAR thingy - how they get to suppress that is beyond me.
So.. yeah.
