We see this "moving" process begin right away. And if new variations of the moving story introduce new problems, no worries mate—just keep changing the story until something theoretically works. It doesn't have to be pretty or even plausible, just a link in a chain of events that points to Oswald's guilt. And the Second Floor lunchroom encounter is not a pretty link—it's ugly. It's crappy. It's doesn't work, but it's the best they got.
Why not stay with Baker's first statement: "As we reached the third or fourth floor I saw a man walking away from the stairway"? No x-ray vision needed to see Oswald through a Second Floor foyer door/window that he wasn't behind anyway. No sitting, standing, or leaning on a counter. Just move Oswald from the First Floor up to the Third or Fourth Floor, have Truly vouch for him there like he did on the Second Floor, and run with it. Much simpler.
There is one good reason that wasn't an option: Victoria Adams.
We'll talk about her next.
