It's quite clear the driver was trying to inform the LEO he had a CCW. At the beginning of the video he said "I've never had to do this" when he was trying to present his permit. If the LEO wasn't being an indignant prick interrupting him, he would have had the compliance he was raging about earlier.
The LEO should be suspended without pay during the investigation. I would hope he would be discharged and furthermore, charged in criminal court.
