I agree, but I think it's too much to hope for that CBS will give up anyone in the Kerry campaign. They'll say they got them directly from Burkett, dealt with Burkett, etc. IF the Kerry people have any sense at all they didn't provide any physical evidence directly to CBS, they probably just helped CBS to get together with Burkett and told CBS that Burkett could be trusted (yeah, right).
I think both Rather/Mapes and Burket/Van Os will go to their graves before they give up Cleland or anyone in the Kerry camp. Unfortunately, I expect the best we can hope for is a major shake-up within CBS and a prosecution of Burkett, but Rather and his pals in CBS will fight to make Mapes the only scapegoat there..... I say fire everyone who touched this story and prosecute Burkett to the limit!
Don't be too sure about Burkett holding info back after they burn him, he's a well documented, A-1, whack job who holds a big grudge. So in that regard we still got hope.
