Mannion goes head-to-head with the U.S. Attorney General and a tough civil-rights lawyer in an emotionally charged episode about child pornography. The investigation into the murder of an 11-year-old girl turns up the child's photo on a porn site, prompting Mannion to seek help from Attorney General Hatcher to toughen legislation against Internet child pornography. But Hatcher has an agenda of his own. In other cases, a congressman asks the chief to look into a case involving the alleged accidental death of his son, and a high-profile lawyer accuses an officer of using excessive force.
