In a throwback to the J. Edgar Hoover-era COINTELPRO investigations targeting civil rights and anti-war activists, the FBI is now training its agents to be on the lookout for “Black Separatist” terrorists, according to FBI training materials released today by the ACLU. These new disclosures, obtained through Freedom of Information Act litigation, are the latest in a growing flood of FBI training materials that include factually flawed and biased information.

The FBI’s apparent concern over a so-called “Black Separatist Threat” first came to light last year, when the ACLU released a 2009 FBI Atlanta Intelligence Note that purported to examine this “threat,” in part by charting the growth of the black population in Georgia from 2000 through 2015.
