The American Civil Liberties Union sued the FBI on March 21 for records related to a divisive 2017 report that said Black extremists were on the rise following the shooting deaths of several African-Americans.

The lawsuit filed in U.S. District Court for Northern California names the Federal Bureau of Investigation and the Department of Justice. The ACLU and its foundation were joined by the Center for Media Justice, based in Oakland, Calif., as plaintiffs.

The lawsuit stems from an intelligence assessment released by the FBI in 2017 that said โ€œBlack identity extremistsโ€ were targeting law enforcement after police killings of Black men. At the time, the agency said it doesnโ€™t target specific groups and noted the report was one of many.

But the report alarmed civil rights activists who remember a time when the U.S. government targeted and harassed Black people and Black-led organizations.

โ€œThe public deserves to know whether the FBI is wasting valuable resources to target those who object to racism, police violence against Black people, and injustice in America,โ€ said Malkia A. Cyril, co-founder and executive director of the Center for Media Justice, in a statement.

FBI spokeswoman Tina Jagerson said March 21 that the agency does not comment on pending litigation.

The lawsuit says the FBI failed to respond adequately to public records requests seeking documents dating to 2014 that contain phrases such as โ€œBlack nationalist,โ€ โ€Black identity extremistโ€ and โ€œBlack separatist.โ€ The requests also seek records that reference โ€œextremistโ€ violence by Black people.

The FBI said that the requests lacked โ€œenough descriptive information to permit a search.โ€

Nate Jones, director of the FOIA Project of the National Security Archive at The George Washington University, said the FBI โ€œgoes out of its wayโ€ to conduct bad and incomplete searches when faced with a regular records request.

โ€œThey follow the law when theyโ€™re sued,โ€ he said.
