On March 17, 2012, Occupy Wall Street demonstrators attempted to mark the movement's six month anniversary by reoccupying Zuccotti Park. Protestors were soon cleared away by Police, who made over 70 arrests. Veteran protesters said the force used by police was the most violent they had witnessed and a Guardian reporter witnessed a protester being slammed into a glass door by a "burly police officer, resulting in a large crack in the glass."
