Police needs to be sensitized no doubt. Instead of listening to that guy and diffusing the situation the officer himself acts like a kid to further escalate matters with his provocative finger pointing. He was there to control things wasn't he?
Another thing, the riot control force seems completely off guard to handle the crowd. Also, shouldn't they be using rubber batons?
But most importantly, where are the parents who should have been the first line of the protesting group?
