I may be one the who 1st  floated that 12:16 BRW leaving earlier time , which was a mistake on my part if I’m going with Arnold Rowlands as a credible witness.

I looked up Arnold Rowland WC testimony and that’s when I found where  he was looking back about every 30 secs after he saw  BRW at 12:15 which means he saw BRW not just one more time at 12:20 but every 30 secs AFTER that until about 12:24 and THEN at 12:25 , he no longer saw BRW.

I generally agree with most of your arguments except the notion the shooter would not have assembled the MC rifle sometime earlier than 12:00 because imo the 7th floor was available ( which is like an attic)

If that’s the case, though the shooter had to have transported the rifle multiple times inside the bag for it to ever have wound  up in the SN. ( unless Bag was moved there after the fact by Fritz team)

So it’s possible after transporting rifle in bag to the SW 6th floor and taking rifle out of  bag such that he was seen by Rowland at 12:15, the shooter after backing away, put the rifle back in the bag, then he had to hide the rifle again (if he is Oswald ) and go back down to 2nd floor lunchroom to be seen
By Carolyn Arnold at 12:17.

However if the shooter is not Oswald then he wouldn’t have to go back down at all. In fact he could have found some spot on the NE corner of the floor where he could have hidden and taken his rifle with him in the bag once more.

This is where it gets into time trouble for the shooter to have arranged the 3 boxes before 12:25 if BRW is still on the floor till 12:24.

And once BRW did leave the floor that late , the shooter must have carried the rifle in the bag one last time to the SN and left it there.

For this hypothetical scenario to be plausible would require  the shooter was wearing gloves as he handled bag ( with he had gotten Oswald’s prints on ) and while the shooter fired the  rifle

Rowland was a complete clown. By the end of his testimony they were making fun of how ridiculous his answers were.

Present a single piece of credible evidence that places Oswald in the SN at 12:30pm.

I suppose you could make a dumber statement, but it is hard to imagine how.

Present a single piece of credible evidence that places Oswald in the SN at 12:30pm.

Can you explain how anyone could know that or why it is even important to know that? Of course you can't. There is ample evidence  that Oswald was in the sniper's nest at 12:30 firing the shots that killed JFK. The fact you think it is important to know where Oswald was in the minutes leading up to the assassination reveals just how dumb you rare.

The is zero credible evidence that Oswald was in the SN at 12:30. Zero.
You are so dumb you don't know the difference between a fact and a theory.
Talking about your dumbness...let me spoon feed to you exactly what is going on in this thread.
I am demonstrating a specific pattern of evidential fabrication, manipulation and omission by the Warren Commission, designed to create a false narrative that placed Oswald all alone on the 6th floor after everyone else went down to lunch.
The fact you don't think it's important that the Sham would do such a thing just shows what a rabid Nutter you are.

On top of the testimonies of Williams, Givens, Lovelady, Arce and Piper the Sham had to 'ignore', was the testimony of Arnold Rowland who observed a man with a scoped, high-powered rifle on the 6th floor. This testimony should have been the centrepiece of the Sham's narrative regarding Oswald's movements leading up to the assassination. Instead it was quietly dropped in a most devious fashion but not because of the man with the rifle. The problem with Arnold's testimony was the black male he reported seeing in the SN window who disappeared a few minutes before the motorcade arrived in Dealey Plaza. It was also notable what Rowland didn't see. His gaze constantly returned to the 6th floor as he scanned the windows looking for the man with the rifle and what he didn't see was BRW sat at the third set of windows along. Instead he saw a black man in the SN window.

Nobody could have a rational debate with someone as stupid as you. You think the most trivial things are important while ignoring the compelling evidence that Oswald was the assassin. That is not an assumption. An assumption is a belief made in lieu of evidence, such as all theories that anyone except Oswald took part in the crime. The fact that you obsess over trivialities such as a supposed elevator race prior to the assassination reveals just how clueless you are. You focus on all the dumb stuff while ignoring what is important. Sorry, just being honest.

I didn't expect for a second that you would actually engage in any kind of rational debate.
That would require far more knowledge about the evidence than you possess, not to mention a bit of backbone.
All you've done is misrepresent and insult. You have offered nothing and will continue to do so.
You really should run along.

You still don't get it and you never will. Witness estimates regarding time frames don't establish anything because they are nothing more than guesses.

As usual, the moment you try to engage with this subject you end up looking buffoonish. Your lack of knowledge regarding the basics of this case is ridiculous.
Norman states that he and Junior Jarman decided to go up to the 5th floor after hearing that the motorcade was on Main Street:

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 beck in the building, James Jarman and I.

The motorcade joins Main Street at Harwood Street and it is a matter of a few minutes before the motorcade reaches Dealey Plaza. When we look at the transcripts of the police radio transmissions we find that the earliest mention of Main Street is around 12:22pm.
This is not a guess.
Norman timestamps their decision to go up to the 5th floor with his reference to the motorcade being on Main Street.

You are so pitifully stupid that you think every word of testimony the WC heard over the course of the investigation should have been included in the report

It would be kind to call this statement 'moronic'.
'Devious' would be a better description.
The point I'm making, as I'm sure you are aware, is that your precious Warren Commission Sham left specifically left out any testimony or statement that ,contradicted the false narrative they created with the insertion of Givens' false account of going back up to the 6th floor and seeing Oswald. This is beyond dispute which is why you have to resort to such crass misrepresentations. You are incapable of providing any kind of rational excuse for the WC's actions. You have to resort to lies and misrepresentations instead. It's really weak-minded.

What the hell difference does it make what time BRW joined Norman and Jarman

You really do need to be spoon fed, don't you?
If BRW didn't go down to the 5th floor until 12:25pm or later, it leaves no time for Oswald to assemble the rifle in the SN as your precious WC Sham would like everyone to believe.
The problem the Sham faced was that there is no time for Oswald to assemble the rifle before BRW was on the 6th floor and not time for him to assemble the rifle after BRW has left the 6th floor. They had to create a false narrative to give Oswald time to do this before BRW was in position.
So they invented the nonsense about Givens going back up to the 6th floor and seeing Oswald near the southeast corner. The importance of this lie was having Oswald refusing to go down to the first floor. This gave him time to prepare the SN and assemble his rifle.
But the testimony and statements of Williams, Givens, Lovelady, Arce and Piper told a very different story - Oswald was looking to get down to the first floor but Givens refused to stop and let him on the elevator. So Oswald called down to them to send the elevator back up to him so he could come down. Whether he got the elevator or not is unknown but what we do know is that he did indeed get down to the first floor, as his interaction with Piper proved.
In reality, Oswald was down on the first floor around 12:00 noon, approximately the same time BRW was arriving at the 6th floor where he would stay until at least 12:25pm.

This whole train of thought is predicated on the assumption the rifle was disassembled in the first place and/or LHO had no opportunity to assemble the rifle on a different floor between the hours of 8:00 to 12:30.
