OWS claims the violent ones are not members of their movement. There is a simple way of testing their veracity. Next time masked men break windows, have the bank security officers shoot them dead. If the attackers are not part of the OWS organization, the OWS will not protest their deaths. On the other hand if the OWS decry the death of these attackers, then the OWS incorporates vandalism, and violence as part of their movement and methodology. Lock and load, and let the test begin.
OWS is nothing but the American version of Arab Spring, all funded most likely by Soros.
... and nobody notices.
I think that all the people who got any property damaged should sue the mayor(Seatle) for letting it happen. There was plenty advance warning.
