In my citythe cops act in a similar fashion. During the NCAA playoff riots, they actively targeted anyone with a camera and let the rubber bullets fly. I saw one reporter from the Daily Wildcat (the UofA paper) get shot point blank with a beanbag gun. The force was so great she literally did a somersault!

During the anti-war protests, the cops started arresting some anarchists who showed up. Anyone taking pictures was threatened with arrest. Fortunately the Legal Observers showed up!

Par for the course.
