Killian's initials and/or signature appear on most of the four memos. The analyst also was called upon to gauge the authenticity by presumably looking at style, stationary, etc.
CBS should have disclosed who gave them the documents and represented them.
I agree with Howlin that there are probably other memos on Bush as well as others but they weren't spinnable as negative (The only one in this group that looks hinky is memo 4 and that isn't about Bush directly so BD).
To clarify my previous comment: Memo 4 does indeed mention Bush directly. What I meant was Killian writes of "pressure" about Bush, but not *from* Bush.
This memo cries out for the author to clarify but alas, he's dead. IMO CBS should not present it. It seems laughable to have to point out the obvious: Especially in light of their ignoring of credible and documented allegations about Kerry from living and breathing people that were with him in Vietnam or suffered at his hands (POWS in prisons).
Well, CBS is disgusting. No use in writing another memo about that!
