Peter Henning, law professor at Wayne State and former Securities and Exchange Commission enforcement attorney, commented about the insider-trading case of former Qwest chief executive Joe Nacchio. Forty-two counts of illegal insider trading were brought against Nacchio in a federal grand jury indictment alleging that he sold $100.8 million in Qwest stock in 2001 as he hid the company's financial troubles. \"This has to be one of the largest insider-trading cases ever brought,\" said Peter Henning, a former Securities and Exchange Commission enforcement attorney and a law professor at Wayne State University in Detroit .
