I don't think you understand how LEO works in this country. Not all the police cars are equipped with audio/video recorders, ones that do may not work for hundreds of reasons.
The point is a police officer should not call an old white lady, "a dumb old efin b**ch who has no efin clue about how to efin drive."
The man is claiming he was called the A word. In case you didn't notice he is pretty pissed about it, strong enough reason for him trying to create an awareness program.
He just may cause the driver to lose his job, causing the driver to become a burden on the tax payers, and some folks may fondly call him the efin leeche.
