Was this Vidographer doing anything Illegal in this video, when threatened with arrest for filming?

The officers were wrong. They were picking on the camera guy and not the other people who were there. It's not against the law to record houses, people, or cops, which was the reason they gave. The camera guy did not have to follow a unlawful command. He also is not required to go to a media area if other citizens are allowed to roam about. If he were breaking some law, he would have been arrested. Go see the video in the link.
