By March 2017, the fight over the construction of the Dakota Access pipeline had been underway for months. Law enforcement was ... discussing plans with Energy Transfer, the parent company of the Dakota Access pipeline. Throughout much of the uprising against the pipeline, the National Sheriffs' Association talked routinely with TigerSwan, Energy Transfer's lead security firm on the project, working hand in hand to craft pro-pipeline messaging. Documents, released by the North Dakota Private Investigation and Security Board, reveal how TigerSwan and the sheriffs' group worked together to twist the story in the media so that it aligned with the oil company's interests, seeking to pollute the public's perception of the water protectors. The private security firm pushed for the purchase, by Energy Transfer, of hundreds of thousands of dollars worth of radios for the cops. TigerSwan also placed an order for a catalog of so-called less-lethal weapons for police use, including tear gas. Off the Record Strategies, the public relations firm working for the National Sheriffs' Association, coordinated with the opposition research firm Delve to track activists' social media pages, arrest records, and funding sources. The companies sought to paint the protesters as violent, professional, billionaire-funded, out-of-state agitators whose camps represented the true ecological disaster, as well as to identify movement infighting that might be exploited.
