You have Baker/Truly following Lovelady/Shelley, "a few seconds later"? So how does Baker/Truly NOT see Lovelady/Shelley directly in front of them as all of these people are simultaneously moving diagonally across the LARGE TSBD 1st floor? Also, why would Lovelady/Shelley want to go to the freight elevators and then just lay around there? That area of the 1st floor is an absolute cesspool. My opinion is that Adams/Styles got their timeline screwed up. They probably see Shelley/Lovelady knocking around the TSBD from time-to-time and just got confused as to exactly when they saw them. It's a leap putting Shelley/Lovelady laying around the freight elevator within a minute after the Kill Shot. They literally have no reason to be there at that point in time. None.
Your only counter-argument is that Baker should have seen Shelley and Lovelady ahead of him??
You seem to imagine that the first floor is a wide open, empty space.
It's nothing of the sort.
You also seem to imagine that everyone travelled in the same straight, diagonal line that led directly from the entrance of the first floor to the elevators. (What makes you think they travelled in a diagonal line anyway?)
I can't help it if you have no idea how cluttered this space was.
At least you've grasped the concept that Shelley and Lovelady could just move into this space while Baker and Truly were interacting in the lobby.
As I said, it's not a difficult concept to grasp.
Your counter-argument is really weak which is very telling.
You are having a problem visualising what is happening because you imagine the first floor to be empty. Once you grasp how cluttered it was it might become clear why Baker didn't see Shelley and Lovelady near the back of the first floor.

So, that's your main counter-argument dealt with.
What else do you have?
Also, why would Lovelady/Shelley want to go to the freight elevators and then just lay around there?
Lay around there?
What are you talking about?
What are you imagining?
That the first floor is this wide open, empty space with a few hammocks in it?
It's hard to discuss these issues with someone who can't grasp the basic realities of the situation.
What makes it even harder is that you never pay attention to what anyone else is posting.
Look back a few Replies and you'll see I posted this:
The question is - what were they up to?
What were they covering up?
What is there, towards the back of the first floor, that could be so important?It has been demonstrated beyond any reasonable doubt that Shelley and Lovelady lied about their movements.
The lied to cover up their real movements.
They lied to cover up the fact that they immediately made their way towards the back of the first floor where they were seen by Adams and Baker.
That they lied is not up for debate.
My opinion is that Adams/Styles got their timeline screwed up.The reason your opinion is wrong is because it is based solely on the lies of Shelley and Lovelady.
They literally have no reason to be there at that point in time. None. You literally have no idea if that is true.
Just because you can't imagine what they are up to doesn't mean anything.
They were witnessed in that area approximately 50 - 60 seconds after the shooting. Just because it's not clear what they were doing there
doesn't mean they weren't witnessed there. That would be a crazy way to look at things.
