The timeline for Norman's and Jarman's presence on the first floor is sketchy. Harold Norman said on his 12/4/1963
" About 12:15 P.M. on this same date, after I had eaten my lunch, I went to the fifth floor of the building to watch the parade of the President pass the building. Bonnie Ray Williams and James Jarman, who also worked at this building went with me. We took a position in the south-east corner of the building on the fifth floor and I was looking out the window which is closest to the east end of the buuilding overlooking Elm Street."
So lets look at what Harold Norman provided........all of it.
Norman was not interviewed by the DPD immediately after the assassination. He was interviewed by the FBI on the 26th of November, the Tuesday following the assassination. As with Jarman's initial statement there was no mention of Williams joining he and Jarman just before the shooting, just that the three were watching the motorcade "about noon" from the fifth floor.
The Secret Service interviewed Norman in the first week of December.

I Harold Norman, wish to make the following statement to Special Agents William Carter and Arthur W. Blake, United States Secret Service.
I am 25 years of age, and I live at 4858 Beulah Street, Dallas, Texas. I do not have a telephone at my residence. I have been employed as an order filler at the Texas School Book Depository, 411 Elm Street, Dallas, Texas for about three years.
I was acquainted with Lee Oswald during the time that he was employed at this company, but I never did get to know him well. I have spoken to him briefly to say "Hello" or in connection with my work, but I never carried on any conversations with him. He did not mix with the employees and did not appear to want to make friends with me or any of the others. I never saw him at any time other than in the building at work.
On the 22nd of November, 1963, to the best of my memory, the last time I saw him was about 10:00 A.M. when we were both working on the first floor of the building. I did not speak to him at that time.
About 12:15 P.M. on this same date, after I had eaten my lunch, I went to the fifth floor of the building to watch the parade of the President pass the building.
Bonnie Ray Williams and James Jarman, who also worked at this building
went with me. We took a position in the south-east corner of the building on the fifth floor and I was looking out the window which is closest to the east end of the building overlooking Elm Street.
Just after the President passed by, I heard a shot and several seconds later I heard two more shots. I knew that the shots had come from directly above me, and I could hear the expended cartridges fall to the floor. I also could hear the bolt action of the rifle. I saw some dust fall from the ceiling of the fifth floor and I felt sure that whoever had fired the shots was directly above me. I saw all of the people down on the street rut towards the west side of the building, so I went to that side with Williams and Jarman, and looked out the west side window. We discussed the shots, and where they had come from and decided we better go down stairs. We walked down the stairs to the first floor and did not see anyone else on the stairway as we went down. From the time of the shots until we started down-stairs was about five minutes.
I have read over the above statement and it is the truth to the best of my knowledge.

Secret Service Report extracted from CD87 states that about 12.15pm "....
he and Bonnie Ray Williams and James Jarman, both employees of the depository,
went to the fifth floor to watch the Presidential motorcade pass by."
March 18 FBI Interview
Just before he testified before the Warren Commission Norman provided a brief statement. It added little to his story. He simply stateed he was with Jarman and Williams on the 5th floor at 12.10 or 12.20 and it appears that he felt the shots occurred at this time. Again there was no indication that Williams had joined them at the windows just before the motorcade from the floor that the shots came from minutes later.
March 24 Warren Commission Testimony
When did they leave the front of the building to go upstairs?
Mr. NORMAN. Well, we stayed there I believe until we got the news that the motorcade was coming down, let's see, is that Commerce, no Main, because Commerce- we went back in the building,
James Jarman and I.
Note that for the first time, 4 months after the shooting, he states that only he and Jarman ascended to the 5th floor.
According to Dallas police radio logs the motorcade was at Ross at 12.20 and Live Oak at 12.22. This would have placed it at Main about 12.24pm.
So I suggest the best evidence provided by Norman was that they started to go upstairs about 12.24. It took them a t least a couple of minutes to get into position. they arrived at about 12.26 or so. This might explain why neither of these two report anything about the Belknap seizure and ambulance arrival as they were on their journey around the back of the TSBD and up the elevator. Interestingly Williams fails to mention the ambulance arrival in any of his statements, I wonder why he might not mention that (time-stamped) event as it was raised by other key witnesses (Brennan and Rowland come to mind). The "final" official story has Williams descending from the sixth floor after Jarman and Norman are in position......so he vacates his position no earlier than 12.26pm.
