In his new book The Watchers: The Rise of the America's Surveillance State , Washington, D.C., reporter Shane Harris chronicles 25 years of the intelligence community's efforts to "connect the dots" on terrorist threats in the United States.
Harris explains why we should have caught the Christmas Day bomber, how one promising electronic surveillance system was wiped out due to privacy concerns, and what it's like to be a spy in the age of Google.
In his day job, Harris covers electronic surveillance, intelligence, and counterterrorism for National Journal.
