Many Americans starting with the president " thought movement activists like King posed threats to the established order and needed to be watched and controlled. Members of the press could have exposed the bureau's campaign. And many government officials who could have stopped, curtailed or exposed the F.B.I.'s attack on King instead enabled or encouraged it. F.B.I. records declassified in the past several years and documents from the Johnson archives released in 2022 force us to reconsider the nature of Johnson's involvement in the F.B.I.'s campaign against King.
