I was surprised to learn this…
As I describe it in my book, Blood and Politics: The History of the White Nationalist Movement from the Margins to the Mainstream (pp. 144 – 171), the federal government has never won a sedition case against militia-types, white supremacists, or neo-Nazis. Since World War One, they have won numerous seditious conspiracy cases against Puerto Rican independentistas, communists and others on the left. But no one on the radical right has ever been convicted of plotting to overthrow by force of arms the government of the United State of America.
Not that federal prosecutors haven’t tried.
During World War Two, two sets of indictments were brought against as many as thirty people with sympathies for the Axis powers. The first one was dropped shortly after it was made. A second set of charges were thrown out of court in 1943. Finally, in 1944, 28 leaders from the Silvershirts, the German-American Bund, the Defenders of the Christian Faith and other National Socialist types were brought to trial in Washington D.C. on charges of sedition. The trial ended after eight months, however, when the judge died. Neither the Roosevelt nor Truman administration re-tried the case.
Ahh yes, but now that the commies have taken over, maybe they can win one against the nazis.
