December 4, 2011  (Washington, DC)  U.S. Park Police officers struggle to remove a man from the top of a structure built by OccupyDC protesters at the McPherson Square park.  The man, whose name is "Mark" according to a fellow occupier, was the last of 31 people arrested by police.  The structure was being built to help Occupy protesters make it through the winter months.  At this point, a Park Police spokesman said there were no plans to dismantle the entire encampment and completely remove protesters.  (Photo by Don Baxter/Media Images International)
