HOW FAR SHOULD THE CIA GO TO PROTECT AMERICA?

"48 HOURS PRESENTS" The Broadcast Network Premiere of "THE SPYMASTERS - CIA IN THE CROSSHAIRS"

Saturday, May 21 (9:00-11:00 PM, ET/PT)

What are the rules in the war on terror for America's spymasters? Will the next president bring back waterboarding as an "enhanced interrogation technique?"

The broadcast network premiere of 48 HOURS PRESENTS: "The Spymasters - CIA in the Crosshairs" raises those questions and more as it takes viewers inside the inner workings of the CIA through the eyes of all 12 living directors of the agency. The directors talk openly about tough calls they've had to make, the controversies they have faced and what it takes to be a master spy.

"I found that I was making decisions on life and death as a director," former CIA Director Leon Panetta says in "The Spymasters - CIA in the Crosshairs," to be broadcast Saturday, May 21 (9:00-11:00 PM, ET/PT) on the CBS Television Network."And those decisions are never easy, and, frankly, shouldn't be easy."

In emotional, no-holds, barred interviews, the directors and their top operatives open up about the role of the agency, the impact being inside has had on their lives, their failures and successes, and their own internal battles and heart-wrenching moments over what's right and wrong in protecting America's citizens.

Their introspective and revealing interviews come at a time when issues of national security are at the forefront of the ongoing race for the White House. Indeed, Republican candidate Donald Trump has said he would "bring back waterboarding" and "I'd bring back a hell of a lot worse."

"If some future president is going to decide to waterboard, he better bring his own bucket because he's going to have to do it himself," says former director Michael Hayden. "The agency is not going to do this again."

Narrated by "HOMELAND's" Mandy Patinkin, "The Spymasters" focuses on the CIA during one of the most controversial periods in its history, marked by the use of enhanced interrogation, secret prisons, drone warfare and even alleged assassination. The documentary raises key questions such as how far should America go to prevent another terrorist attack? What is fair game in an unfair fight? And has the agency focused too much on lethal paramilitary action at the expense of gathering intelligence.

"The Spymasters" also gets inside the events leading up to the 9/11 terrorist attacks and the hunt for Osama bin Laden.

"I don't think you can go through that kind of experience, of having to make life and death decisions. Having to every day, read intelligence about all of the evil that's out there in the world and those who want to strike at us, and not have it affect you," Panetta says.

The directors also look to the future and what the CIA, and the country, face in terms of fighting terrorism.

"You can't kill your way out of this," says George Tenet. "That's a mistake. It's much more complicated."

The directors featured are President George H. W. Bush, Stansfield Turner, William Webster, Robert Gates, James Woolsey, John Deutch, George Tenet, Porter Goss, Michael Hayden, Leon Panetta, David Petraeus and John Brennan. In addition, the documentary features interviews with Michael Morell, two-time acting director and CBS News Senior Security contributor; John McLaughlin, acting director; Chiefs of the Counter Terrorism Center, Cofer Black and Jose Rodriguez; and Gina Bennett, CIA Senior Counter Terrorism Analyst.
