-- Dressed in yellow full-body sanitation suits, members of the U.S. Park Police combed through tents in the Occupy DC camp Saturday, taking down ones violating park policies.
The owners of the tossed tents and other protesters were agitated by the move, but there was little unrest at McPherson Square in downtown Washington.
Park police in riot gear first entered at dawn Saturday, and said they were not there to evict protesters, but to check for compliance with "no camping" laws.
Still, at one point, there was a confrontation between protesters and riot police.
