Thousands Flood Streets of D.C., NY to Protest Police Brutality

The Millions March NYC: Day of Anger protest takes place today. Anti-police-brutality demonstrators plan to march from Washington Square Park up to Herald Square and back downtown again to One Police Plaza—NYPD headquarters.
Several streams are available to watch the protests: Ustream and CBS News are both supplying live feeds. (CBS is providing aerial shots of the protests.) Here is the RT stream embedded, via YouTube:
There is not a count, yet, of how many people are turning out for the demonstration, but it looks crowded. 49,000 people said that they would attend the event on Facebook.
