The pond scene and the window breaking because these tell suburbia that the demonstrators are hoods. Some articulate, positive statement made by those involved. That's a reason. Presenting the demonstration without the reasons is as bad as presenting the reasons and not reporting the demonstration. Reporting needs balance.
Violence makes news.
It's too bad, but that's how it is. Different newspapers report the same event differently. That part that showed the doors closing could be a great thing about the deaf ears of the Supreme Court. If I just had the evening news, I'd begin with the marchers, mark the size of the crowd, and tell why the march was held and what the grievances were. For human interest, I'd use the old lady and reinforce her with Abernathy.
