The FBI coordinated take-down plans with local police, DHS, and big banks. That much seems pretty clear. If you read carefully, you'll see that that's actually an insinuation made by the organization that filed the FOIA request, not something they actually proved. The actual documents they produced only show that various organizations within and outside of the FBI communicated about OWS at various times. There's nothing inherently unusual or nefarious about this -- those organizations are in communication all the time on any number of topics. That a nationwide mass protest movement often targeted specifically at banks and speckled with anarchist overtones happened to be a topic discussed by a nationwide security organization is...not actually that surprising. It would actually be more surprising, and troubling, if they hadn't known or communicating anything about OWS at all.
