When did Holmes say "from the top floors"?
Keep in mind that you are relying on specific details from the man who came up with this gem:
"But he went downstairs, and as he went out the front, it seems as though he did have a coke with him, or he stopped at the coke machine, or somebody else was trying to get a coke, but there was a coke involved. He mentioned something about a coke."
I hardly need to tell you this, Mr Iacoletti, but you shouldn't expect a coherent response from Mr Nessan.
Mr Holmes got things a little garbled, but he is crystal clear on one thing: Mr Oswald said the encounter with the cop took place at the front entrance, first floor. Which is exactly where the DPD were telling everybody on 11/22 it had happened. Despite never having even been in the Depository, Mr Holmes is able to describe the double doors/vestibule arrangement------because he heard Mr Oswald explain it (probably for the umpteenth time) to Captain Fritz.
The reason Mr Oswald mentioned a coke was that he had one in his hand at the time of the encounter. The reason he mentioned the coke machine on two was that he was explaining where he had gotten the coke from. The reason he mentioned coming downstairs was that he was describing his actions subsequent to his purchase of the coke on two.
The Hosty draft report confirms that this had been Mr Oswald's claim all along.
