DUmmies try to say that anyone committing acts of violence are not members of OWS. That doesn't wash.
Since OWS has no leadership, no structure, no membership requirements, and no self-policing, then anyone who says they are OWS are OWS. If they're there, and they've joined in the crowd and claimed the same goals, then you can't just arbitrarily point a finger and say, "This one is, this one isn't, this one is, this one isn't...", based solely on what you like or don't like about their behavior. Like it or not they are your creation as a result of of your insistence on having no organization, except for the laughable "general assemblies", which spend more time affirming that none of them have more authority than another, and going through monotonous "mic checks" than actually deciding anything.
