White supremacists and other domestic extremists maintain an active presence in U.S. police departments and other law enforcement agencies. A striking reference to that conclusion, notable for its confidence and the policy prescriptions that accompany it, appears in a classified FBI Counterterrorism Policy Guide from April 2015, obtained by The Intercept. The guide, which details the process by which the FBI enters individuals on a terrorism watchlist, the Known or Suspected Terrorist File, notes that “domestic terrorism investigations focused on militia extremists, white supremacist extremists, and sovereign citizen extremists often have identified active links to law enforcement officers,” and explains in some detail how bureau policies have been crafted to take this infiltration into account.
Although these right-wing extremists have posed a growing threat for years, federal investigators have been reluctant to publicly address that threat or to point out the movement’s longstanding strategy of infiltrating the law enforcement community.
