I am not close enough to this story to really comment. No one approves when protests turn violent.
But last September, the local paper The Baltimore Sun published an in-depth report called Undue Force. The opening paragraph:
The city has paid about $5.7 million since 2011 over lawsuits claiming that police officers brazenly beat up alleged suspects. One hidden cost: The perception that officers are violent can poison the relationship between residents and police.
Perhaps more people should have read this…
