re: Ask a cop a question

Ever hear of a police veh (ie Tahoe) with "Doppler" to be able to detect the speed of a vehicle coming up from behind. Not asking if yall have it, but have you heard of the tech to be out there to be picked up.

Serious question. Cop told me that was what he had to gauge my speed, and then he lied about saying it in court. (Gawd I would have the #1 "what cops make up" contender on youtube if I had recorded that stop)
