In Part 3 of America’s First Anti-Terrorist Campaign: The Ku Klux Klan Trials of 1871, Judge Stephen J. Sfekas turns to the federal government’s direct campaign against Klan violence in South Carolina. He follows President Ulysses S. Grant’s use of the Enforcement Acts, the suspension of habeas corpus in nine counties, and the mass arrests that broke the Klan’s power. The episode also examines the major South Carolina trials, including the case against John Mitchell and Dr. Thomas Whitesides, with excerpts from testimony that reveal how Klan violence was organized, carried out, and prosecuted.
