Corporate crimes have become the center of public attention in recent years, resulting from actions of companies such as Enron, KPMG, and Worldcom. While business crimes may not have captured the nation’s attention twenty or even ten years ago, there can be little debate that such crimes now attract much attention. As the prosecution of white-collar crime has evolved and increased during this last decade, this seminar will address the effects of the Holder Memorandum, the Thompson Memorandum, the McCallam Memorandum, the McNulty memorandum, and the Filip Memorandum on the prosecution and defense of corporate crimes. In addition, it will present questions for review regarding ethical issues facing both prosecutors and in-house/corporate counsel while prosecuting and defending corporations involved in white-collar crimes or criminal investigations.
