I am really impressed by lawyers who write books and tell us that they never lost a case. Most lawyers who have never lost a case have not had enough hard cases. But there are very difficult cases out there.

I think that the very fact that CBS fought and fought and fought in Texas, in New York.

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.

It is within the last quarter century or thirty years. And a lot of that law has turned out to be very, very protective of the press and the public's right to know.

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.

I just had the sense that at least the books that I had read about law just didn't really have enough of that.

I would say that the Pentagon Papers case of 1971 - in which the government tried to block the 'The New York Times' and 'The Washington Post' and other newspapers from publishing papers that they obtained from a secret study of how we got involved in the war in Vietnam - that is probably the most important case.
