THE FBI HAS long been concerned about the infiltration of law enforcement by white supremacist groups and its impact on police abuse and tolerance of racism, the unredacted version of a previously circulated document reveals.

The FBI threat assessment report was released by Rep. Jamie Raskin, chair of the House Committee on Oversight and Reform’s Civil Rights and Civil Liberties Subcommittee, ahead of a hearing about the white supremacist infiltration of local police departments scheduled for Tuesday.

A heavily redacted version of the 2006 document had previously been published, one of a handful of documents revealing federal officials’ growing concern with white supremacists’ “historical” interest in “infiltrating law enforcement communities or recruiting law enforcement personnel.” A different internal document obtained by The Intercept in 2017 had also noted that “domestic terrorism investigations focused on militia extremists, white supremacist extremists, and sovereign citizen extremists often have identified active links to law enforcement officers.”

The unredacted version of the first document sheds further light on the FBI’s concerns, as early as 2006, about “self-initiated efforts by individuals, particularly among those already within law enforcement ranks, to volunteer their professional resources to white supremacist causes with which they sympathize.”

“Having personnel within law enforcement agencies has historically been and will continue to be a desired asset for white supremacist groups seeking to anticipate law enforcement interest in and actions against them,” the report notes in a section that was previously redacted.

Another previously redacted section warned of “factors that might generate sympathies among existing law enforcement personnel and cause them to volunteer their support to white supremacist causes,” which could include hostility toward developments in U.S. domestic and foreign policies “that conflict with white supremacist ideologies,” the report warns.

Some redactions do not seem to be justified, for instance, the FBI’s conclusion that “white supremacist infiltration of law enforcement can result in other abuses of authority and passive tolerance of racism within communities served” — an apparent recognition of the potential harm to the public posed by white supremacist individuals embedded in police departments.
