Whistle-blowers expose outrages that come to their attention through access to confidential materials or witnessing illicit behavior. Examples range from Edward Snowden, who revealed the breadth of unauthorized US government surveillance around the globe, to Jeffrey Wigand, who made public the ways in which Big Tobacco was lying about the health risks of smoking and actively looking to make tobacco more addictive. Readers will gather information about the issues, analyze the ethics of blowing the whistle, and draw conclusions to determine—is it worth it?
