	there's a good book about fighting radar speeding tickets.
	(i don't recall the name -- go ask the folks in rec.autos!)
	the units can have calibration problems.  usually the cop 
	has to prove that he has calibrated the unit properly within
	the previous few days...  or some 'suitable' time limit.
	if there were other cars around, he may have gotten a reading
	from a faster car...

	from what i understand, the Vincennes radar made no mistakes and 
	worked as expected under the short range conditions it was being 
	used in.  the radar operator and the captain made the mistake...  
	a comprehensive discussion on this issue can be found in back
	issues of comp.risks.

	military radars and police radars are very different beasts.
	their missions are worlds apart...

>when the radar of a very expensive warship has made them.)

	be careful about asking cops such things!  be real nice!
	good luck with your ticket.  65 in a 55 is one wimpy ticket.
	are the California fuzz usually so picky?
