In the United States, Black Identity Extremists (BIE) was a designation used by the Federal Bureau of Investigation (FBI) from August 2017 to July 2019. It first appeared in a counterterrorism report dated August 3, 2017 sent to thousands of American police departments and described safety concerns about allegedly violent African-American activists. The term was discontinued when the FBI merged several classifications under the umbrella term of “racially motivated violent extremism”.
The term first received media attention in October 2017 when Foreign Policy published a leaked copy of the report in October 2017. According to Foreign Policy, the report is the first reference to "black identity extremists", while also noting the report claims "[t]he FBI assesses it is very likely Black Identity Extremist perceptions of police brutality against African Americans spurred an increase in premeditated, retaliatory lethal violence against law enforcement and will very likely serve as justification for such violence". However, former government officials and legal experts claimed the term described a movement that did not exist. 
Civil liberties organizations and political commentators expressed concern that the internal use of this designation by the FBI's counter-terrorism unit signals a politically-motivated effort to falsely equivocate black activism, such as the Black Lives Matter movement, with white supremacists.
