When members of the Occupy movement were driven out of City Hall park last November, Occupy L.A. moved to Pershing Square to conduct its regular protest planning meeting.

Some demonstrators used chalk to communicate their messages, which resulted in brawls with the Los Angeles Police Department.

Critics claim the demonstrators are causing major damage in the city, which is resulting in pricy clean-up costs.
