To give you a background of this episode, here's a brief history of New Orleans being the capital of corruption. The undisputed champion of the political arts was Huey Long, aka "Kingfish," whose populist program of road building and free schoolbooks propelled him to the governorship of Louisiana in 1928 and later to the U.S. Senate. The levels of graft in his administration were outrageously high even by the standards of Louisiana politics. Though he survived being impeached on charges of bribery, he was assssinated in 1935 by the son-in-law of a political opponent. His legacy remains. In recent years, 14 state judges were convicted of corruption, and more than 50 police officers were convicted of crimes that included rape, murder, and robbery. Two are currently on death row. As a former congressman once said: "Half of Louisiana is under water, and the other half is under indictment."
The Dixie Mafia story was published into a book by Pocket in 1995. It is titled "Mississippi Mud : Southern Justice and the Dixie Mafia (Edward Humes)."
