Bump, just in case David missed my post in the fast moving thread.
I agree with everything you just said, Martin.
My earlier point was not that I believe Oswald was down on the first floor at about 12:25. (As I said previously, I definitely do not believe such a thing.) I merely was pointing out the fact that a 12:25 alibi is not the same thing as a 12:30 alibi. And 12:30, as we all know, is the key time here.
Fair enough, but then there is this; according to some interrogation reports Oswald made some vague comment about two negros being in (or walking through) the room where he was. Unfortunately, we don't really know what Oswald actually said verbatim, so we have to rely on the notes made by the interrogators and their choice of words for writing it in their report. However, having said that, I think that the combined reports do clearly suggest that Oswald did in fact make some comment about negros being in (or walking through) the room.
So, as he identified one of them by name, some time ago, I tried to establish a timeline for the movements of Jarman and Norman prior to their arrival at the 5th floor, and the conclusion was that these two men did indeed pass through the shipping area (visible from the Domino room) just minutes prior to the shooting. I am aware of the LN theory that Oswald first saw Jarman and Norman from the 6th floor window and later heard them talking (and identifying them) below him, which is why he concocted the story of seeing both men, but IMO that's a very weak narrative for two reasons; (1) During my visit to the TSBD, some years ago, I tried to look down to where I understood Norman and Jarman were supposed to have been and found it impossible to see that location from there and (2) if Oswald was able to identify both men by the sound of their voice, IMO those men on the 5th floor should also have been able to hear the movement on the floor above them, prior to the shots, which they didn't!
Which leaves me with a bit of a mystery. If I am being kind to Oswald, I could argue that he was indeed in the Domino room when he saw Norman and Jarman enter the loading area and walking towards the elevators, which means that it is possible that the interrogators simply were not precise enough in their reports.
So, here's the question; since we have already agreed that Oswald could have made it to the 6th floor in roughly the same time Norman and Jarman made it to the 5th floor, why are the LNs fighting so hard to ridicule and dismiss the scenario I have just outlined based on nothing else than those vague (and possibly wrong or incomplete) remarks in the interrogation reports?
