Based on declassified FBI documents, including documents from J. Edgar Hoover’s vault and previously-secret National Archives documents, this is the first full account of the twenty-year legal campaign waged by government lawyers and policymakers, in secret conjunction with private enterprise, to deport radical labor leader Harry Bridges. This is the story of the rise and fall of due process, where those who are supposed to be the very agents of due process—government prosecutors, federal investigators, legislators, and judges—bent and warped the Constitution in a means-justify-ends crusade to silence Bridges’ vociferous labor voice.
