Top Secret America – 9/11 to the Boston Bombings

FRONTLINE goes inside the Washington Post's two-year examination into the massive, unwieldy, top-secret world the government has created in response to 9/11.

FRONTLINE reveals 9/11's unprecedented yet largely invisible legacy: the creation of a vast maze of clandestine government and private agencies designed to hunt terrorists and prevent future attacks on the U.S.

On the 10th anniversary of 9/11, FRONTLINE examines how a decade of fighting terrorism has reshaped the country and whether it has made us any safer.

In his first televised interview, John Rizzo, a 34-year agency veteran described as "the most influential lawyer in CIA history," tells FRONTLINE that even before Obama became president, his team signaled "they were going to be just as tough, if not tougher, than the Bush people."

On Obama's inauguration day, all of Top Secret America was on hand to protect the incoming president. "What was happening behind the scenes was phenomenal," "Washington Post" journalist Dana Priest tells FRONTLINE in "Top Secret America," coming Sept 6.

Have the hundreds of billions of dollars spent since 9/11 on counterterrorism efforts made us safer? On April 30, Pulitzer Prize-winning reporter Dana Priest traces the journey from 9/11 to the Boston Marathon bombings, examines efforts to improve information sharing among federal agencies tasked with keeping us safe and investigates the secret history of the 12-year battle against terrorism.
