Explores Martha Stewart's December 2001 sale of ImClone Systems common stock, the ensuing federal investigations into possible insider trading, and Stewart's criminal prosecution and sentencing. Discusses the impact of publicity on Stewart's company, Martha Stewart Living Omnimedia, and on her personal image, and raises issues of prosecutorial discretion. Challenges students to consider the validity of the insider trading charge against Stewart as well as the securities fraud charge included in the indictment, the appropriate sentence, and whether federal authorities unfairly singled out Stewart for investigation.
