The FBI counterterrorism division's identification of a movement it calls black identity extremists" is the latest addition to the list of protesters and dissidents the agency puts under the "domestic terrorism" umbrella. But many national security experts say the designation [is] simply a label that allows the FBI to conduct additional surveillance on "basically anyone who's black and politically active," said Michael German, who left the FBI in 2004. While the practice of labeling certain protest groups as domestic terrorists is not unique to President Trump's administration, Hina Shamsi ... at the American Civil Liberties Union, said there's concern that "abusive and unjustified investigations" by the FBI are rising. The problem, Shamsi said, is partly in the overly broad definition of domestic terrorism in the Patriot Act as a violation of the criminal laws ... intended to "influence the policy of a government by intimidation or coercion." Eighty-four members of Congress cited that intention to intimidate or coerce in a letter to the Justice Department last week that asked whether the department had labeled Dakota Access Pipeline protesters domestic terrorists. The Justice Department did not respond to questions about the letter. The FBI report that focused on black identity extremists ... had interest groups questioning whether the designation has been used to single out members of Black Lives Matter.
