On this scenario, the 'investigating' authorities know that Mr. Oswald didn't do the shooting, and wasn't the man Officer Baker caught by the rear stairway. Mr. Truly tells them he honestly thought it was Mr. Oswald--------and now has no idea who it can have been. The authorities don't really believe him, but all efforts must now go into pinning the crime on Mr. Oswald. FBI cooks up the lunchroom story, and Mr. Truly comes on board as a compliant witness.
Mr. BALL. At that time didn't you know that one of your officers, Baker, had seen Oswald on the second floor?
Mr. FRITZ. They told me about that down at the bookstore; I believe Mr. Truly or someone told me about it, told me they had met him--I think he told me, person who told me about, I believe told me that they met him on the stairway, but our investigation shows that he actually saw him in a lunchroomCaptain Fritz's flustered word salad tells the story here: down at the bookstore we were told that a worker had been met on the stairway, but it took
an investigation afterwards to establish that no, actually it was in a lunchroom
Here's Mr. Truly and Officer Baker on one afterwards:
No doubt Officer Baker has mentioned to law enforcement what he saw. And Mr. Truly knows he has a sighting of a man he vouched for as a worker---------a man whom the officer caught walking away from the rear stairway several floors up the building----------to explain away in a manner that is not lethal to himself.
Enter Mr. Oswald......................
