Livingstone phonecall- Harper Frag Flew Off Head in Other Nix;4d in Nov & Gary Mack(?)Study Overlaid

#Harry Livingstone courtesy Alex Harris YT chan takes call from a "Doug Mizer" who must be a lesser-known researcher or A/V guy who found something. Livingstone implies he is tech expert. Obviously knows him, Harris uses his name as if he knows him too.
Big white chunk flying off JFK's head, that ISNT THERE in the extant Nix film. also good discussion on ea rly doubts for Z film. I dont know if Livingstone of Lifton called the forgery first but IIRC Lifton mentioned it in Best Evidence early 80's
I think Gerda Dunkle the youtube clip designer is Gary Mack, whose given name was Dunkel or Dunkle. ai search reddit for details. This is a significant contribution, I think from the early 2000s. Did he have a change of heart, or working both sides the whole time IDK, but I do know every conspiracy guy on JFK circuit hates him, sees him as Judas. None of them would put out this excellent study to rehab his image, which looks like he marked it with an easil-decipherable pseudonym we can tell it's him. None of his friends/people who gave him lots of money would want this. Look at the grass in the enhanced, it isn't enhanced, it's BLURRED to cover up the edits.
Seoncondly, why a re there things in Groden's study not in the "enhanced"/extant Nix? Did they remove things from the Groden, or *add them to the Groden*???
I did a short compilation on Mack/"Dunkle" study & the Groden film re: badgeman/black dog man flashes here-
