Since TG's OCD requires us to live with two Mary Woodward threads, I guess I will have to post my insightful contributions on both, to wit:
We have failed to mention wacky Mary's FBI interview of 12/7/63. It's clear she crossed from Houston to Elm. Nothing about the grassy knoll. It conveniently omits the timing of the second and third shots.
She doesn't omit the timing of the second and third shots. She says: "There seemed to be a pause of a few seconds, and then there were two more loud noises which she suddenly realized were shots..."
By mentioning a pause after the first of a few seconds and then two shots but not mentioning a similar pause between them, she provided a description that is consistent with her DMN story although with less specific detail. Also, those words were written by the FBI. The DMN story and her 1988 THWKK clip were all her words.
