Leaked documents and public records reveal a troubling fusion of private security, public law enforcement, and corporate money in the fight over the Dakota Access Pipeline. By the time law enforcement officers began evicting residents of the ... resistance camp near the Standing Rock Sioux reservation on February 22, the brutal North Dakota winter had already driven away most of the pipeline opponents. It would have been a natural time for the private security company in charge of monitoring the pipeline to head home. But internal communications between TigerSwan and its client, pipeline parent company Energy Transfer Partners, show that the security firm instead reached for ways to stay in business. Indeed, TigerSwan appeared to be looking for new causes, too. The ... firm's sweeping surveillance of anti-Dakota Access protesters had already spanned five months and expanded into Iowa, South Dakota, and Illinois. TigerSwan became particularly interested in Chicago. [Leaked] documents dated between February 19 and February 21 describe TigerSwan's efforts to monitor an anti-Trump protest organized by the local chapter of the Answer Coalition, an anti-war, anti-racism group. Answer Coalition's ... John Beacham, who organized the protest TigerSwan described, said that [the NoDAPL movement] was not the event's primary focus. "They're trying to make connections where they aren't. It's almost like they're trying to cast conspiracy theories across the entire progressive movement," he told The Intercept.
