Exactly 10 years ago this week, the FBI warned of the potential consequences - including bias - of white supremacist groups infiltrating local and state law enforcement, indicating it was a significant threat to national security. In the 2006 bulletin, the FBI detailed the threat of white nationalists and skinheads infiltrating police in order to disrupt investigations against fellow members and recruit other supremacists. The bulletin was released during a period of scandal for many law enforcement agencies throughout the country, including a neo-Nazi gang formed by members of the Los Angeles County Sheriff's Department who harassed black and Latino communities. Similar investigations revealed officers and entire agencies with hate group ties in Illinois, Ohio and Texas. Much of the bulletin has been redacted, but in it, the FBI identified white supremacists in law enforcement as a concern, because of their access to both "restricted areas vulnerable to sabotage" and elected officials or people who could be seen as "potential targets for violence." The memo also warned of "ghost skins," hate group members who don't overtly display their beliefs in order to "blend into society and covertly advance white supremacist causes." "At least one white supremacist group has reportedly encouraged ghost skins to seek positions in law enforcement for the capability of alerting skinhead crews of pending investigative action against them," the report read. In the 10 years since the FBI's initial warning, little has changed.
