It was in Eastern Washington, and I lived in Western Washington. If I had had a tape recorder on at the time I would have gone over there to fight it. No way the cop would tell the truth about this in court, and the judge would have said "it is your word against the officer's, and I have no reason to believe that the police officer is lying." I'd heard that one too many times before.
Then he didn't write the ticket for "Failure to signal while being pulled over"?
