I am equivocal on this one.
First and foremost, the Officer was out of line. It was a non threatening situation and his reaction was completely unwarrented.
Second, the kid had a camera recording. IMHO, that will happen only if he was intending to pull some stunt (ultra high speed, drifting, etc.) or if he was just looking to get pulled over and harasses by the Law. Not only that, once the Officer went balistic, the kid seemed to bait him by prodding him with the response that was irking the Officer in the first place. Seems fairly obvious that the kid wanted a conflagration.
