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.

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

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.

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 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.

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.
