Just a little advice: If your going to file a motion for discovery, and request copies of the speedometer calibration, radar log books, etc., then make sure that you intend to build a defense with them. The quickest way to piss off a judge is to start filing pre-trial motions for "no apparant reason". Part of your right to due process, is to be able to file a motion for discovery prior to trial. SEB127 is right, the multi-directional radars came out in the early 90's. I operated one before I promoted out of the Highway Patrol. I would also exceed the speed limit at times, just to give the opportunity for "tailgaters" to exceed the speed limit. As for your radar detector, Well......do you want to pit your $300.00 detector against a $3500 instrument? I really believe that if you understood the technology with current doppler traffic radar, you wouldn't put much faith in detector. Our Troops eat radar detectors for fun. Trust me, they get you into more trouble than they are worth. I haven't seen too many drivers with detectors get "warnings" for speeding. The general philosophy on that is...."You wanna play, then your going to pay".
I encourage you to exercise your right to trial, if you truly think that you were not in violation. Good luck and stay safe.[soapbox]
