And for what? So that he can later correctly "guess" that exactly those two men he saw on the sidewalk would walk around the building and enter it at the back at a location that can be seen from the Domino room, some 5 minutes prior to the assassination.
Thank You, Martin..... You've pointed out the most ridiculous part of Myton's insane fabrication. I once had some respect for Myton.... Now I simply pity him. He clearly cannot reason rationally......
Huh? For as long as I can remember you have always been calling me names which shows absolutely no respect so stop your never ending urge to fabricate, it just erodes whatever credibility you had left which now stands at less than zero!
Oswald before the unexpected assassination had no qualms about being seen and in fact exposed his entire head and torso by sitting on the window sill as testified by Howard Brennan(*1) and as Oswald had left most of his money and wedding ring with Marina, Oswald knew there would be no return from his murderous act which is exemplified when Oswald attempted to kill Walker, Oswald's note specifically says "
IF I am alive and taken prisoner"(*2) Oswald is fully aware of what the outcome would be if he murdered someone which is reinforced by Oswald's insightful comment after killing a Police Officer, "Well, you fry for that,".
And as for the reason for Oswald scoping the street below would be, and as I have always maintained is to check out who was where because some of Oswald's fellow workers did discuss watching the Presidential Parade from the sixth floor(*3) and we know Bonnie Ray did in fact come up to Oswald's sixth floor which would have made Oswald even more determined to see if anybody else would follow in the footsteps of Bonnie Ray. So seeing Jarman and Norman disappear would have made Oswald nervous but fortunately for Oswald and unfortunately for Kennedy they both went to the fifth floor.
The reason for Oswald wanting to maintain control over his immediate destiny is abundantly clear and the fact that I am encountering so much hostility only means that you guys know it too.

Mr. BELIN. At the time you saw this man on the sixth floor, how much of the man could you see?
Mr. BRENNAN. Well, I could see at one time he came to the window and he sat sideways on the window sill. That was previous to President Kennedy getting there. And I could see practically his whole body, from his hips up. But at the time that he was firing the gun, a possibility from his belt up.(*2)

Mr. BALL. You say you went back upstairs. Where did you go?
Mr. WILLIAMS. I went back up to the sixth floor.
Mr. BALL. Why did you go to the sixth floor?
Mr. WILLIAMS. Well, at the time everybody was talking like they was going to watch from the sixth floor. I think Billy Lovelady said he wanted to watch from up there. And also my friend; this Spanish boy, by the name of Danny Arce, we had agreed at first to come back up to the sixth floor. So I thought everybody was going to be on the sixth floor.JohnM
