Mr. BALL - What did you do when you got to the fifth floor?
Mr. JARMAN - We got out the elevator and pulled the gate down. That was in case somebody wanted to use it. Then we went to the front of the building, which is on the south side, and raised the windows.
Mr. BALL - Which windows did you raise?
Mr. JARMAN - Well, Harold raised the first window to the east side of the building, and I went to the second rear windows and raised, counting the windows, it would be the fourth one.
Mr. BALL - It would be the fourth window?
Mr. JARMAN - Yes.
Mr. BALL - Did somebody join you then?
Mr. JARMAN - Yes, sir; a few minutes later.
Mr. BALL - Who joined you?
Mr. JARMAN - Bonnie Ray Williams.
Since it appears, imo, that the 5th floor window IS open in the Bronson film, then it is reasonable probability that Norman has raised it just before Bronson film begins not earler thatn 12:25, so likely Norman did get there by AT LEAST 12:24.
That means Norman/Jarman had to have left from front of TSBD not later than 12:22pm, treked 250 ft at 5 ft pers second, around the perimeter of the TSBD so entered the rear door approx 45 sec then 35 sec to take elevator to 5th floor at 1 floor per 7 sec speed, then walked acoss about another 160 tt in 40 sec, so its reasonable probable time required of 2 minutes to be at their windows and have raised the windows.
For Jarmans statement that BRW joined them "a few minutes later" ie: at least 2 minutes later, means that if Norman and Jarman left at 12:22, and dont get to their windows untill 12:24, then BRW did not join them until 12:26
This is improbable, since the 6th floor SE shooter has to have been IN the snipers nest approx by 12:23 to have some time to choose on the spot, which boxes he wants to move, and or stack, and gets this done by 12:24 and also hides himself from view of the Bronson film perspective.
What reason would Jarman and Norman have had to leave EARLIER than the 12:22 radio news the JFK limo was about to approach?
