This video has been around for a few days, but it really didn't look interesting enough to watch. But I heard someone mention it on the radio this morning so I gave it a shot.
A guy gets passed by a speeding cop, honks at him, so the cop stops him for "unlawful use of the horn." Their initial interaction is a little contentious, but no big deal. Right before the cop leaves to go run the guy through dispatch, he is informed that he is being recorded. When the cop returns, the attitude change really is amazing. He goes OVERBOARD in being nice. I'm really surprised by that. I figured he'd still issue a ticket and come across as Joe Friday: professional and brief.
