Book excerpt: "'Keystone Corruption: A Pennsylvania Insider's View of a State Gone Wrong' traces the cyclical nature of misconduct in Pennsylvania government over the course of the last hundred years. Most of the book focuses on corruption since the 1970s, when the author had a front-row seat during the unprecedented scandals of 2007 through 2012. . . The book is not intended as a complete history. It includes the author's impressions of powerful legislative leaders and top aides who abused the taxpayers in ways that did not, like many of the allegations against them, land in criminal court. When it came to crimes, from Bonusgate to Computergate and the "BIG" caper-Bumsted tracked the cases at every turn." -- Cover page 4.
