The big issue is this incremental whittling away of our constitutional rights, our most important constitutional rights, including freedom of speech. This is something that we really have to put our foot down on, and we have to fight it at every step of the way.

It's not up to Google, it's not up to Apple to turn over our personal communications in order to save the country. It's up to the CIA and it's up to the FBI to recruit foreign - I mean to recruit human sources, rather, to penetrate these groups.

I had never really given any thought to working for the CIA, but graduation was upon me; I was getting married just a week or two after graduation; I had no job, no prospects for a job. And so I said sure, I'd be interested in working for the CIA.

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.
