Koppel Defends "The Fallen": "I thought it would get attention, but did I think it would become so controversial, did I think that people would feel the need to question the patriotism of those who are putting it on the air? Did I think that it would descend to the depths of some people suggesting we were doing this because the networks are going into a sweeps period when ratings become important?

You start to wonder after a while. I've been doing 'Nightline' for over 24 years, I've been at ABC for 41 years, if that's really the impression I've left with people then I have failed in such a colossal way that I can't even begin to consider the consequences of it."
