The "kill the SOB" is directly from Russo as quoted by McAdams. Congradulations for actually reading the link but you missed this part.
I don't think you took the trouble to really read your own "source"
"As wild as Crenshaw's most recent story is, it appears to have been toned down compared to the original. Harrison Livingstone, for example, has claimed that the first version of Crenshaw's manuscript had Johnson calling and demanding, not that Oswald be gotten to confess, but that Oswald be killed. The Kennedy Assassination Home Page has been unable to confirm the existence of that manuscript, but the early version of the story was as Livingstone describes.
One of the researchers who was privy to this early version was Gus Russo, author of Live By The Sword. As Russo describes it:
When Oliver Stone was in Dallas prepping for JFK, a number of us were around as "technical advisors," which was a bit of a joke, since Stone only listened to people with crazy conspiracy info.
One night at the Stoneleigh [Hotel], Stone was having a slew of top secret meetings in his suite with people like Ricky White, whom Stone paid $80,000 for his fraudulent story, and the positively goofy Beverly Oliver. That night, Stone ushered Gary Shaw, [Robert] Groden and Crenshaw into his room; I was not invited, but I pressed Shaw (Crenshaw's and Oliver's advisor) for info in the lobby. He was the first to tell me that LBJ ordered Oswald killed. Later, Crenshaw came down, and we happened to be in the Stoneleigh men's room at the same time, standing at adjacent urinals. It was there that he told me that Johnson had ordered the Parkland staff to "kill the son-of-a-bitch." It was decided to "drown Oswald in his own blood," i.e. transfuse him until his lungs collapsed. (E-mail to the author dated August 25, 2003) "
So it's Livingston taking the story from Gus Russo (not invited to the meeting), who took it from Shaw who got it from who? Crenshaw?
Not hearsay, eh?. I'd say hearsay via four different sources, not that I believe a word of it -- the part, that is, where Johnson tells the docs to commit murder. Not even LBJ is that dumb.
Morever, "Her reason for never having spoken of the incident was twofold. One, she had not considered the call unusual under the circumstances, and, secondly, because she felt that there was a possibility that the call might be a prank, she had remained on the line for a short period after connecting the call-an act which was against hospital policy."
"Ms. Bartlett also explains why the line went dead as Dr. Crenshaw describes. She had disconnected the call in an attempt to transfer the call to a newly set-up public relations [office], feeling upon reflection that that office might be in a better position to handle such a call."

I really think the honorable thing for you to now do is issue yet another retraction and an apology for calling Dr. Crenshaw a "liar" and that would also mean an another apology for calling Ms. Bartlett a "confabulator" which of course means a "liar." I guess by your estimate and McAdams estimate, all the doctors and nurses at Parkland got together with the teleophone operator to create the biggest lie ever known. Shameful accusations. Dishonest research.
