Fun laser story (this happened about 2 months ago):
I came around a blind corner on the freeway I drive daily to work, exceeding the speed limit by a "bit". Parked on the side of the road, standing outside their patrol car was a CHP officer aiming a laser gun right at me. I passed by and looked in the rear view mirror, I observed the officer open the door of their patrol car, throw the laser gun on the seat and enter the vehicle. The chase was on!
Not too far beyond where the officer was standing was another blind corner in the freeway, and just around the blind corner was an off ramp. So instead of slowing down, I put the pedal to the metal and headed for the off ramp. I exited the freeway, and entered onto the road that parallels the freeway. Out my window I observed the CHP officer speed by, still on the freeway, beyond the off ramp, lights flashing, trying to catch up with me.
Go to the web site of your favorite Radar or Lidar speed measuring devices and try to download the owners manual. You won't be able to because you needed a password that is only given to law enforcement. The whole system relies upon the ignorance of the public.
In David's & Peter's situation the speed measurements were based on radar, not lidar.
The only radar speed detector "spec" of any consequence is how much history is specified by the manufacturer. That information is in the users manual, the manual they won't allow you to view or download without a law enforcement password. It may be that the new radar stuff won't give the officer a "pass" until a sufficient amount of good data (i.e. stable measurements) have been collected. So the history defense may be a thing of the past with the newest equipment.
Do you know why the law enforcement agencies are switching to laser? Because its harder to fight the tickets. More revenue! That's the only reason. There is no evidence that the incidents of speeding are on the rise, requiring an expenditure for better equipment. It just bothers them that a few people fight and win each year, they consider that lost revenue. They don't like to loose court cases against everyday Joes. If the goal was simply to get people to slow down and obey the speed laws, all they would have to do is increase visibility, get more officers on the road where they can be seen. When they are hiding, waiting to catch speeders, the intention is not to enforce law, but to write tickets, generate revenue. Its not the officers fault, they are doing what they've been told to do. Its the policy makers, the politicians.
My recommendation is still to go to the web sites that specialize in beating speeding tickets:
