The truth of the matter is, we can certainly fight against terrorism and fight terrorist groups around the world without having to give up our own civil liberties. They're not mutually exclusive.

I've never heard a White House staff say that the president was too stupid or too ill-informed to have broken the law. And that's really what it comes down to. The truth is, he leaked highly classified information that he shouldn't have leaked. It's one thing to say, "Hey, I'm the president. Nobody can punish me for that." It's another thing entirely to just deny that he did it. We know that he did it. And he really ought to own up to it.

If the CIA is going to disrupt future terrorist attacks, it needs to recruit spies to infiltrate those groups in order to disrupt the terrorist attacks. Not to rely on what you and I are putting in chat messages on Google or Apple.

You can't just blurt the information out to the Russian foreign minister and the Russian ambassador. What happens is, the information goes back to the CIA, to the originating office. The CIA will pull the relevant information out of the report, put it on a new blank sheet of paper and then type at the top, "Secret releasable to Russia." That way, nobody gets in trouble, no sources and methods are revealed, everybody's happy, and we can establish something of a liaison relationship to the Russians. That's not what the president did.

Even if torture works, it cannot be tolerated -- not in one case or a thousand or a million. If their efficacy becomes the measure of abhorrent acts, all sorts of unspeakable crimes somehow become acceptable. I may have found myself on the wrong side of government on torture. But I'm on the right side of history. There are things we should not do, even in the name of national security. One of them, I now firmly believe, is torture.

Immediately after the September 11th attacks, I volunteered to go to Afghanistan in any capacity that the CIA wanted me. Four months passed before I was able to go overseas, just because my skill set was not one that was important in those really early days after the attacks.

It's much less romantic in that you have to go to www.cia.gov and click "Apply Now." For me it was much more clandestine.
