MTG:
Thanks for your collegial comments.
Verily, Connally is recorded as saying what he said to LIFE magazine, and being shot at Z-234.
I don't understand that. He also said he was pushed forward, bent over by the impact of the shot and immediately incapacitated. That seems to happen at ~Z-295.
That Z-295 shot also jives with the sequence of shots many heard, the well-known "bang...bang, bang" sequence.
While I believe in a small conspiracy, I also believe the JFKA immediately became a litmus test for ideology and agenda (see the Kirk assassination and Trump assassination attempts for how this works out).
There are actually lefties suggesting Trump faked the Butler attempt, and that he was not really grazed by a bullet on the top of his ear. Ideologies and agendas are stronger than truth.
LIFE magazine wanted to LN version to prevail. Did they accurately quote Connally, or lean on the photos they showed him? I dunno. LIFE magazine also reported JFK turned in his seat and faced the TSBD before being shot in the throat as seen...in the Z-film, which only they had.
In brief, I believe my own eyes on the Z-film, and nothing in LIFE magazine, circa 1960s, re the JFKA.
IMHO, caveat emptor and draw your own conclusions.
