Can cops really do this?

WRONG! They do not have to show you in GA. The only thing they have to do is "test" the radar in terms of calibration.

These "urban legends" kill me...

CORRECT! lol...you muct have gotten alotta tickets too. However, if the officer is going to issue you a speeding citation where a radar speed detection device was used, then the officer has to offer to test the device for proper calibration prior to issuing the speeding citation, however, you have no right to watch the test being conducted.

you have to subpoena the maintenance records of the radar system, as well as the maintenance records of the tuning forks sometimes used to calibrate the radar systems. This isn’t a defense you should attempt without an attorney to represent you.

Another radar system defense is to prove that the officer wasn’t properly trained and qualified to operate a radar system, and in fact operated the radar improperly.
