We are living in a time of mind-boggling corruption, but we are also, as it happens, living in a golden age of whistleblowing. Over the past two decades, the brave insiders who decide to expose wrongdoing have gained unprecedented legal and social stature, emerging as the government's best weapon against corporate misconduct--and the citizenry's best defense against government gone bad. They are also forcing us to consider fundamental questions about our democracy, especially the proper balance between free speech and state secrecy, and between individual rights and corporate power. 2019.
