The philosopher Socrates was tried for impiety and corrupting the youth of Athens. He was found guilty and executed in 399 B.C. Next week, he will be tried again—but in Chicago, not Athens.
The Trial of Socrates, organized by the National Hellenic Museum, will feature a lot of legal star power. The presiding judge will be 7th Circuit judge, law professor, and prolific author Richard Posner. You can read or hear an interview with one of the prosecutors, U.S. Attorney Patrick Fitzgerald, here (NPR Weekend Edition, Jan. 26, 2013).
For the history, see The Trial of Socrates, by Prof. Douglas O. Linder. It's just one of many trials for which Linder presents essays, transcripts, images, and more on his Famous Trials site.
