Someone's nationality has relevance?
It's the critics who couldn't handle the truth. Lane and Thompson, who interviewed her, didn't like her non-confirmation of a grassy knoll shooter.
Only late in life, influenced by books and TV, did she off-handedly allow the possibility. But she was always consistent from early on about the black couple's actions and that there was no gunman behind the fence.
The parameters of rationalizing start when you ignored the most important part which makes Sitzman completely inconsistent. The fact that she contradicted herself means she was inconsistent. Not a big deal since LHO was never convicted.
Since we both know what she said, that would be another witness of yours who would fall short of helping your narrative. Completely useless to you, but more important another hostile witness caught playing make-believe.
Since we know Mr. Zapruder's film was altered and since we know he was a native of Ukraine which fell under the umbrella of the Soviet Union then we can say it is very fishy. LHO wasn't born there. Who would have ever thought, old man Zapruder with his perfect cover? You wouldn't suspect a haberdasher, would you? Don't be lazy, start looking at shady Abraham. Something just is not right about that guy.
