The point is that the cop used massively excessive force preportional to the crime. The man obviously has some anger issues for him to show such aggression over a minor, and rather common, by-law infraction committed by barely-teenagers. Its not like he beat the shit out of someone or anything--but the point is that the potential is there. If he reacts this way to a freaking kid who is skateboarding in a park, its not a stretch to imagine him pulling a Rodney King. And thats something the public should be concerned about. Police officers shouldn't be man-handling 14 year old kids for skateboarding.
