Governments and corporations now have the tools to track and control us as never before. In this whistleblowing how-to, we are provided with tools and techniques to fight back and hold organizations, agencies, and corporations accountable for unethical behavior. Can one person successfully defy a globe-spanning corporation or superpower without being discovered? Can a regular citizen, without computer expertise, release information to the media and be sure her identity will be concealed? At a time we're told we are powerless and without agency in the face of institutions such as Google, Facebook, the NSA, or the FBI, digital security educator Tim Schwartz steps forward with an emphatic "yes." And in fewer than 250 pages of easy-to-understand, tautly written prose, he shows us how. A Public Service can teach any one of us the tricks to securely and anonymously communicate and share information with the media, lawyers, or even the U.S. Congress. This book is an essential weapon in the pervasive battle to confront corruption, sexual harassment, and other ethical and legal violations.
