"Trivial detail"? She reversed the order of her going inside the shelter with her traveling down and up the knoll. And, there are No Images or Eyewitnesses to back up her claiming to seeing a Black Couple sitting on the Bench and busting pop bottles as they ran up The Steps. Yet, alleged "researchers" are accepting her tale as being fact. This is why this case remains unresolved almost 60 yrs later. Uncorroborated 
being freely distributed as Fact.
To provide some context to this Sitzman interview, Josiah Thompson flew into Dallas for a scheduled interview of Zapruder at the Dal-Tex Bld. At the last minute, Zapruder canceled the interview, leaving Thompson to then quickly pivot and instead interview Sitzman who was working there at the Dal-Tex Bld. Thompson never did manage to get an interview with Zapruder, even though his best seller, "Six Seconds In Dallas", was based on images filmed by Abe Zapruder.
"Trivial detail"?It doesn't seem possible to you that she mentions things that seem relevant to her in the interview? Standing in the alcove wasn't relevant. Going down the hill and telling people JFK had been killed seemed relevant. Going back up the hill and talking to someone who ID'd themselves as a federal agent seemed relevant. Standing in the shelter didn't seem relevant so she didn't bother mentioning it. It's a totally trivial detail that didn't need mentioning. You seem to expect that she would give Thompson a microscopic analysis of her every move.
The only problem is that you think it is relevant and, as usual, you're wrong.
And, there are No Images or Eyewitnesses to back up her claiming to seeing a Black Couple sitting on the Bench and busting pop bottles as they ran up The Steps.This is typical of how you half read something and just make up the rest.
Nowhere in her interview with Thompson doe she mention seeing a black couple running up the steps. You've made this up but you probably don't even realise. It's typical of the standard you display as a "researcher". Then you get all wound up because nobody else saw something you made up.
It's a really poor standard.
For the record - When she first arrives at the pedestal, Sitzman is aware of a black couple sat on the bench we see in Darnell. She pays no further attention to them, she is interested in the motorcade.
The next time she becomes aware of them is after the limo enters the underpass and she hears breaking glass which draws her attention to the couple leaving the area of the bench in a hurry and running towards the back of the shelter.
This is why this case remains unresolved almost 60 yrs later.The main reason the case remains unresolved is due to people like yourself who feel free to make up any old
they feel. It's become an industry that has completely swamped this area of research. For people genuinely trying to understand the case, far more time is spent dealing with
theories than anything else.
And the LNer community get a free ride because genuine researchers who are Cters can be brushed off as belonging to a bunch of crazies.
