But if Adams really went down the stairs as early as she claimed, it would only mean she was ahead of Oswald.
For once you get something right. Well, kinda....If he was on the 6th floor, there is no way that Oswald - who would have needed to run roughly twice the distance Adams did, hide the rifle and go down two floors - could have beaten Adams and Styles to the stairs on the 4th floor. So, if he did come down the stairs, he would indeed have been behind the two women. But he wasn't as Dorothy Garner would have seen him! Rankin understood this, which is why Adams was not at the reconstruction and why the Stroud letter disappeared in Adams' file.
The Shroud letter is hearsay with no specifics. Styles said it was more like minutes than seconds when they left the window and even then they first went to the passenger elevator.
Same with the radio straw man claim; Oswald in the SN wouldn't need it. He could see the streets still sealed off for the motorcade, policemen at the intersections and crowds waiting.
The radio claim came from Richard Smith. It was his straw man!
For Richard, it's only a possibly:
"No one is saying that Oswald definitively heard the police reports of the motorcade
progress. Only Oswald could know that. He certainly could have, however."
"He could hear the noise from the street below him. Did he hear the police progress
reports? No idea. Only Oswald knows for sure. No reason that he needed too, though,"
The straw-man goes back six days ado to Skeptic-Tank's "Only a team with radio communication would be able to relay the actual accurate progress of the motorcade." Just now, Richard wrote: "We have certainly come a long way from the original claim that only a top-secret team could know the motorcade progress"
Just like his (and your) pathetic claim that Oswald, in the SN, could have seen Jarman and Norman walk around the building.
Oswald from the SN window most certainly could have seen Norman and Jarman standing together on the sidewalk below. He then heard the two arrive below his window some minutes before the motorcade arrived. They were talking and throwing open windows. Unless Oswald had sight and hearing issues, I don't see any problem with that proposal.
