A compilation of thoughtful essays that look at the constitutional foundations and limitations of the U.S. government in a contemporary context, this book examines how laws and freedoms collide in cases where individuals leak information to the media. The book clearly explains how the U.S. Supreme Court has interpreted laws that pit freedoms against government interests, and considers how the Internet world and big data are affecting privacy. It is a practical guide, in easy-to-understand language that journalists, lawyers, and government officials will find to be of great value. At last, a clear and somber explanation of the issues involved in balancing secrecy, security and transparency in our democratic society. This book should help replace overheated rhetoric with reasoned debate.
