The FBI memo states that law enforcement had recently become aware of the term “ghost skins,” used among white supremacists to describe “those who avoid overt displays of their beliefs to blend into society and covertly advance white supremacist causes.” [White supremacy/racism is carried out through deception & violence. Racists are white degenerates who suffer from the mental illness of comparison & although they are unable to produce color & lack melanin, they nevertheless imagine themselves to be separate & supremely atop of a make believe hierarchy of all existence wherein they imagine themselves to be higher than what they imagine you to be]. Like falling out of a tree, there really can be no set plan or code made to deal with such persons who are also "police officers" in the for-real world. Only awareness can help you deal with a psychopathic, maniac cop.  

From [The Intercept] WHITE SUPREMACISTS AND other white 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.

No centralized recruitment process or set of national standards exists for the 18,000 law enforcement agencies in the United States, many of which have deep historical connections to racist ideologies. As a result, state and local police as well as sheriff’s departments present ample opportunities for white supremacists and other right-wing extremists looking to expand their power base.

In a heavily redacted version of an October 2006 FBI internal intelligence assessment, the agency raised the alarm over white supremacist groups’ “historical” interest in “infiltrating law enforcement communities or recruiting law enforcement personnel.” The effort, the memo noted, “can lead to investigative breaches and can jeopardize the safety of law enforcement sources or personnel.” The memo also states that law enforcement had recently become aware of the term “ghost skins,” used among white supremacists to describe “those who avoid overt displays of their beliefs to blend into society and covertly advance white supremacist causes.” In at least one case, the FBI learned of a skinhead group encouraging ghost skins to seek employment with law enforcement agencies in order to warn crews of any investigations.

That report appeared after a series of scandals involving local police and sheriff’s departments. In Los Angeles, for example, a U.S. District Court judge found in 1991 that members of a local sheriff’s department had formed a neo-Nazi gang and habitually terrorized black and Latino residents. In Chicago, Jon Burge, a police detective and rumored KKK member, was fired, and eventually prosecuted in 2008, over charges relating to the torture of at least 120 black men during his decadeslong career. Burge notoriously referred to an electric shock device he used during interrogations as the “nigger box.” In Cleveland, officials found that a number of police officers had scrawled “racist or Nazi graffiti” throughout their department’s locker rooms. In Texas, two police officers were fired when it was discovered they were Klansmen. One of them said he had tried to boost the organization’s membership by giving an application to a fellow officer he thought shared his “white, Christian, heterosexual values.”

Although the FBI has not publicly addressed the issue of white supremacist infiltration of law enforcement since that 2006 report, in a 2015 speech, FBI Director James Comey made an unprecedented acknowledgment of the role historically played by law enforcement in communities of color: “All of us in law enforcement must be honest enough to acknowledge that much of our history is not pretty.” Comey and the agency have been less forthcoming about that history’s continuation into the present.

IN 2009, SHORTLY after the election of Barack Obama, a Department of Homeland Security intelligence study, written in coordination with the FBI, warned of the “resurgence” of right-wing extremism. “Right-wing extremists have capitalized on the election of the first African-American president, and are focusing their efforts to recruit new members, mobilize existing supporters, and broaden their scope and appeal through propaganda,” the report noted, singling out “disgruntled military veterans” as likely targets of recruitment. “Right-wing extremists will attempt to recruit and radicalize returning veterans in order to exploit their skills and knowledge derived from military training and combat.”
