This book addresses the investigation and prosecution of public and political corruption. It focuses on the investigation of the former Attorney General of Pennsylvania, Ernest Preate, who was convicted of mail fraud and served 15 months in Federal prison. The various political machinations that confronted the Pennsylvania Crime Commission when it decided to pursue the investigation of Preate are used to educate the reader on what to expect when and if he or she initiates an investigation of a powerful political official. The author who dedicated over 30 years to investigating the Mafia, political corruption, narcotics trafficking and money laundering addresses a myriad of investigative conundrums in the investigation of complex crimes. He describes the practical implications of enforcing laws that a significant minority of the population chooses to disobey and the corruption that emanates from this disrespect for the law. The author takes you on an eye-opening journey into the world of criminal justice, which often is permeated by raw political and financial power.
