The group protesting is ANSWER...the same ones who started the Anti-Cop chants in NYC.
Excerpt from Powerline: A.N.S.W.E.R., a Communist organization that was founded in September 2001 and that organized substantial antiwar demonstrations during the Bush administration. A.N.S.W.E.R. embodied within itself the seeming contradiction between the far left and Islamic extremism: it enthusiastically supported both Kim il Jung and Saddam Hussein, and is directed in part by the Muslim Student Association.

Excerpt from Wikipedia: ANSWER characterizes itself as anti-imperialist, and its steering committee consists of socialists, communists, civil rights advocates, and left-wing or progressive organizations from the Muslim, Arab, Palestinian, Filipino, Haitian, and Latin American communities. Many of ANSWER’s lead organizers had ties to the International Action Center, and Workers World Party at the time of ANSWER’s founding.[3]
