In respect to the 2nd floor encounter in the lunchroom w/the wrongly accused, It did not happen. It's that simple really. First, let's take into account the actual truth before a hastily contrived script after the fact rears its deceptive offerings:
Marrion Baker's same day affidavit (bold emphasis mine to illustrate a key point ---->
AFFIDAVIT IN ANY FACT
THE STATE OF TEXAS
COUNTY OF DALLAS
BEFORE ME, Mary Rattan, a Notary Public in and for said County, State of Texas, on this day personally appeared M. L. Baker, Patrolman Dallas Police Department who, after being by me duly sworn, on oath deposes and says:
Friday November 22, 1963 I was riding motorcycle escort for the President of the United States. At approximately 12:30 pm I was on Houston Street and the President's car had made a left turn from Houston onto Elm Street. Just as I approached Elm Street and Houston I heard three shots. I realized those shots were rifle shots and I began to try to figure out where they came from. I decided the shots had come from the building on the northwest corner of Elm and Houston. This building is used by the Board of Education for book storage. I jumped off my motor and ran inside the building. As I entered the door I saw several people standing around. I asked these people where the stairs were. A man stepped forward and stated he was the building manager and that he would show me where the stairs were. I followed the man to the rear of the building and he said, "Let's take the elevator." The elevator was hung several floors up so we used the stairs instead. As we reached the third or fourth floor I saw a man walking away from the stairway. I called to the man and he turned around and came back toward me. The manager said, "I know that man, he works here." I then turned the man loose and went up to the top floor. The man I saw was a white man approximately 30 years old, 5'9", 165 pounds, dark hair and wearing a light brown jacket.

SUBSCRIBED AND SWORN BEFORE ME THIS 22 DAY OF November A.D. 1963

Notary Public, Dallas County, Texas
Baker's same day statement alone sums up the actual truth when compared to a hastily contrived script that follows a day later. Moreover, the wrongly accused did Not, repeat did not fit Mr. Baker's description (the wrongly accused weighed in 34lbs less than the individual Baker actually encounters. Again, the wrongly accused weighed only 131lbs, nowhere near 34lbs heavier. Also, it's important to note, the individual was, quote, "walking away from the stairway". What part of this observation substantiates an encounter in a room, let alone a lunchroom floors below?
Again, What part of walking away from a stairway has anything to do with being inside a lunchroom?
The phantom 2nd floor encounter w/the wrongly accused is just that, phantom "evidence" mired knee deep in horse manure amid a hastily contrived script the day after to frame an innocent party.
The wrongly accused did not shoot anybody. Anybody.
