What idiot parent brings their 4-year old to a protest, where there is a fairly high likelyhood that police may have to use force to quiet or disrupt an unruly crowd.
The parents of the 4 year old should be charged with endangering a child.
Also, it sounds like things were fine until one 'peaceful' protestor attacked the cameraman and his like $100,000+ camera.
Not a wise idea. That is an act of aggression, and the police are justified to use force at that point.
The cameraman was 'assaulted' what does that mean? Someone shook a fist at him? Pointed a gun? The proper term would be 'struck' or 'battery' if he were hit.
