I dunno, Karin. I think the DC police will stare at all this in complete befuddlement, only because it's so stupid.
Same thing happened in Madison, WI. Cops basically stood around and let the hippies shit all over the place. When the hippies wore their welcome out after, what a week?, then they started busting heads -- gingerly, since the cameras were rolling.
The DC cops are not inclined to start busting caps or heads -- not yet anyway. But all bets are off when they start shitting on the steps of the Capitol Building -- then it's time for water cannon and Lysol.
