You are just being silly........AGAIN!
What difference does it make when Oswald made these preparations. We know he made the preparations which amounted to assembling the rifle and stacking a few boxes for a rifle rest and a seat. If I had to guess, i would say he probably didn't assemble the rifle until the other employees had left for lunch. Why risk exposing the rifle before then? Stacking the boxes would take about a minute, tops. Bonnie Ray Williams returning to the 6th floor could have been problematic had he remained there but since he didn't, that left Oswald with ample time to make final preparations. If you want to create imaginary problems for Oswald, those same problems would also apply to anyone else you want to imagine could have done the shooting, but that's academic. All the hard evidence tells us the shooter was Oswald.
Spoken like a true Nutter - we know Oswald made the preparations because Oswald did it therefore he made the preparations because he did it therefore...
Let's say a couple of minutes to go back and forth with the Rolling Reader boxes from a few aisles away, a couple of minutes to fetch his rifle from wherever it was stashed and 6 minutes to assemble his rifle. Let's say 10 minutes in total to make his preparations...do you know what...let's go crazy and just say 6 minutes to assemble his rifle.
When did he do that?
"If I had to guess, i would say he probably didn't assemble the rifle until the other employees had left for lunch. Why risk exposing the rifle before then?"You do have to guess because the WC didn't spoon feed you this particular piece of information, which leaves you having to use your own brain to work something out by yourself, which leaves you in real difficulties.
And it's little wonder that you happen to suspect the same narrative the WC report is trying to suggest - at lunchtime everyone from the upper floors goes downstairs except for Oswald, who has business to take care of. Luckily Givens just happened to go back up to the 6th floor where he saw Oswald near the southeast corner and when he offered Oswald a ride downstairs he refused (because he had some preparing to do). He had some boxes to move, a disassembled rifle to fetch which he was then going to have to assemble. As luck would have it, he got all this done before Bonnie Ray Williams arrived on the 6th floor to have his lunch and watch the parade go by.
But he had to be quick because Bonnie Ray went down to the first floor, washed up, fetched his lunch, bought a bottle of Dr Pepper and made his way back up to the 6th floor. He was probably up on the 6th floor before 12 noon, maybe 11:55am.
So Oswald hid quiet as a mouse while Williams had his lunch a few yards away.
Except Oswald didn't go up to the 6th floor after everyone broke for lunch. This was a lie the WC put in the mouth of Givens
Oswald went down to the first floor, just as he told everyone involved in the elevator race he intended to do.
And he talked with Eddie Piper at 12 noon on the first floor, at the same time Bonnie Ray Williams was taking up his position on the 6th floor.
So, when did Oswald have time for all these preparations?
