The 99% mantra works as an invitation to the Big Tent, but as a facade of unity it is dangerously misleading.
There are many of the 99%, not just the police, who will fight us, who will try to destroy us, many who simply don't understand how to transition from a hierarchical culture, who use intimidation to grasp for attention & power and work to undermine and betray the movement... sometimes with the best intentions. Others who are too intimidated by the prospect of disapprobation by authority figures whose smiles and vague promises make them forget whose interests they serve, forget that no matter how 'nice' a mayor or police chief might be, they are inexorably bound up in an essentially undemocratic power structure that exists primarily for the benefit of the few at the expense of the many.
Lets not be overly distressed that when Authority begins to frown, many will scuttle to what they believe to be safety, many will turn their backs on us, others will seek to push us toward a defensive authoritarian response to the perceived threat.
What we have done is already part of history and they cannot destroy what has begun here--not from above, not from within.
Mayor Nutter said in his news conference that Occupy Philly had changed. That the "leaders" had changed. What he meant was, there is no select few who stand apart from the people and pretend to speak for us in our stead, who can be manipulated, cajoled, used for their own ends.
Lets not be fooled. His complaint acknowledges that we're making a difference. That's why they will eventually try to destroy us--no matter where we move.
