Book excerpt: After the landmark Brown v. Board of Education ruling in 1954 mandated the desegregation of schools nationwide, the legislature in the state of Mississippi created the Mississippi State Sovereignty Commission, the basic mission of which was to prevent integration in that state. This book is an investigative history of the Commission, other government agencies (including the FBI), and organized crime, all of which conspired to break the law in dealing with civil-rights and antiwar activists during the 1950s and 1960s. The author uncovers new information about the efforts of FBI agents to combat integration and exposes the longest-running conspiracy in American history.
