Conrad Black was released from a Florida prison Thursday after federal judge Amy St. Eve in Chicago set a $2 million bond that was posted a friend of Black’s, Roger Hertog. Black can’t leave the country, and he must appear before St. Eve this Friday. Black, former owner of the Sun-Times, has served 28 months of the 6 1/2 year sentence St. Eve gave him in 2007 after he was convicted on charges of fraud and obstruction of justice. The fraud convictions were undermined last month when the Supreme Court vastly reduced the scope of the legal doctrine of honest services fraud and remanded the case to St. Eve.
