I can't remember any ethical challenges. There are certain hard and fast rules that all good reporters go by, I think. Here at CBS they're written down in a big thick book called "CBS News Standards and Practices." Dick Salant, the president of "CBS News," started that. He made it a loose-leaf book so that when he thought of new standards and practices to make it and even more ethical calling, he could put it in there. And he did a pretty good job of codifying, as the lawyer that he was, what most of us who were reporters already knew. Which was that you don't gain a story by trickery, you don't, at least I never have, you don't pay somebody for a story, and all those. An infinite number of rules to which most reporters adhere.
