We've seen that citizens are often charged with "resisting arrest" for merely stiffening up when being manhandled by cops.  It seems to have become S.O.P. (Recall that one of the cops arresting someone in a wheelchair at the sit-in at Sen. Gardner's office was heard to shout "Stop resisting!" at the handicapped individual.)  I wonder if these "resisting arrest" charges are included in the "assault on cops" statistics.
