It isn't really laughable as we don't actually have a clue what the lighting situation was in the room at that time.
Were all the lights on?
All the lights??

We don't know.
What stands in Baker's favour on this point is that it was certainly possible it was dim as there are no windows in that room and it is completely dependent on what lights are switched on. If it was a room with windows, on a bright sunny day, it would have been more difficult to understand.
You can't seriously be suggesting that Officer Baker and Mr Truly saw Mr Oswald in a lunchroom where the ceiling light was switched off--------i.e. a dark lunchroom?
The point I was making here wasn't about the colour, it was about Baker misidentifying the shirt as a jacket because it was hanging out.
Officer Baker is making a point about the color: he tries to resolve the color discrepancy between "light brown jacket" and
CE150 by inventing "dim" lighting conditions in the lunchroom. He's being hopelessly helpful in that Whaley kinda way
Mr. BAKER - I could have mistaken it for a jacket, but to my recollection it was a little colored jacket, that is all I can say.
There can be no argument the colour of the jacket Baker gives is light brown and CE151 is described as a light brown sports shirt.
You're quite right that Mr Oswald wore the light brown shirt to work that day. However there is no good reason to believe that the "light brown jacket" Officer Baker described in his same-day affidavit had anything to do with that shirt or its owner. He encountered a man in a light brown jacket by the rear stairway on a floor higher than the second
It is not a massive leap to see how Baker could mistake a shirt for a jacket as it was hanging out.
It is also clear from Baker's testimony that the clothes he sees "Oswald" wearing in the police station are different from those he sees in the TSBD:
Mr. DULLES - Do you recall whether or not he was wearing the same clothes, did he appear to you the same when you saw him in the police station as when you saw him in the lunchroom?
Mr. BAKER - Actually just looking at him, he looked like he didn't have the same thing on.
Mr. BELIN - He looked as though he did not have the same thing on?
Mr. BAKER - He looked like he did not have the same on.
I understand you can't have Oswald in the 2nd floor lunchroom but Baker's description of his clothes can't really be used to support that point.
Wrong place, wrong clothing, zero connection made between man by rear stairway and man just brought in in handcuffs-------------------it's Officer Baker's own affidavit that disallows this as a lunchroom encounter with Mr Oswald.
As for having Mr Oswald in the 2nd floor lunchroom, I do have him there: before the P. Parade, just like he said
