Playbus is right. I don't trust the news in any "he said, she said" stories. There's simply too much going on to be understood from a (biased) news article.
In my opinion: Those skateboarders had it coming to them. Cursing, resisting, and running get you nowhere with an officer. It's funny as hell when they shout "Why are you doing this?" when they give off a "fight the power" vibe with their actions.
