What if the Zapruder film is authentic?

[Albert Doyle]

Nix shows ejecta exiting the rear near the Parkland rear wound.

I can only find either slow motion or enlarged versions of the Nix film, not slo-mo and enlarged, but could what you're referring to actually be the backwards movement of the whole of Kennedy's head, and not ejecta?

There was a post on Lancer 2 years ago or so showing a slow-motion enhanced version of Nix that clearly shows a stream of some kind of material exiting the rear of Kennedy's head. To me what it shows is that Kennedy's head exploded open from one shot. Most likely from the rear.

I think CTer's tend to operate in a dogmatic fashion where you have to accept all CT theories and reject any possible alternate CT theory that has even a hint of validating any aspect of the LN theory. For instance it is very possible the rear wound at Parkland was from the head exploding open - including the rear occipital wound. I have trouble thinking CIA grabbed Zapruder's film and managed to fake the gory skull flap flesh wound. Think to yourself in the limited time they had how they would create such a bloody and meaty wound that was corroborated by witnesses? The exiting spurt seen in Nix conclusively happens at the same time as the exiting spurt from the skull flap wound. In other words it is very likely the same wound.
