As Occupy Wall Street spread across the nation last fall, sparking protests in more than 70 cities, the Department of Homeland Security began keeping tabs on the movement. An internal DHS report entitled “SPECIAL COVERAGE: Occupy Wall Street," dated October of last year, opens with the observation that "mass gatherings associated with public protest movements can have disruptive effects on transportation, commercial, and government services, especially when staged in major metropolitan areas." While acknowledging the overwhelmingly peaceful nature of OWS, the report notes darkly that "large scale demonstrations also carry the potential for violence, presenting a significant challenge for law enforcement."
 
The five-page report –  contained in 5 million newly leaked documents examined by Rolling Stone in an investigative partnership with WikiLeaks – goes on to sum up the history of Occupy Wall Street and assess its "impact" on everything from financial services to government facilities. Many of the observations are benign, and appear to have been culled from publicly available sources. The report notes, for instance, that in Chicago "five women were arrested after dumping garbage taken from a foreclosed home owned by Bank of America in the lobby one of the bank's branches," and that "OWS in New York staged a 'Millionaires March,' from Zucotti Park to demonstrate outside the homes of some of the city’s richest residents."
 
But the DHS also appears to have scoured OWS-related Twitter feeds for much of their information. The report includes a special feature on what it calls Occupy's "social media and IT usage," and provides an interactive map of protests and gatherings nationwide – borrowed, improbably enough, from the lefty blog Daily Kos. "Social media and the organic emergence of online communities," the report notes, "have driven the rapid expansion of the OWS movement."

The most ominous aspect of the report, however, comes in its final paragraph: http://www.rollingstone.com/politics/blogs/national-affairs/exclusi...
