It's not like learning how to hit a curve ball in baseball.

I thought that one of the things that we were losing sight of is the basic reasons that we do protect free speech and freedom of the press and the essentiality and centrality in our lives of really giving broad protection to freedom of speech and freedom of the press in America. I thought I could do that by telling stories of some of the cases that established those principles on a real life on the ground basis.

If the word gets out, if the perception exists that by speaking to a CBS journalist you are, therefore, inevitably, immediately speaking to the police, I don't think there's any doubt but that people won't talk. And, therefore, the public won't learn.

I really do think that if we had lost that case we would really live in a country that would be really quite different.

So sometimes the facts are good and sometimes the facts are bad, the important thing from the point of view of a principle as broad and important as freedom of speech is that the courts articulate and set forth in a very protective way what those principles are.

I really believe that a lawyer - no matter how good - if he or she is really worth their weight in salt, they will lose some cases because, after all, it is not really one of those secretive things that not everything is decided by who your lawyer is.

That doesn't necessarily mean that the story isn't true, ... But what it does mean, then, is that at this moment we simply do not have enough evidence, in my view, for any conclusion to be reached - that the presidents have been lying to us for all these years and that what we've been told was just a pack of lies.
