An explosive look at the domestic agencies charged with spying on all of us Given recent terrorist events in the U.S. and the document leaks by NSA whistleblower Edward Snowden, The Watchers is more timely than ever, drawing on access to political and operational insiders to create a brilliant exposé of why and how the American government spies on its own citizens.

Despite the cost, it has failed in its mission to identify new threats. But as Harris shows, it has provided the government with a tool for the electronic surveillance of Americans that has ushered in an age of constitutionally questionable intrusion into the lives of every citizen.
