Dr. Costella: Uncovering the Probable Techniques Used to Alter the Zapruder Film in Nov.1963

I posted a shorter version of this a while ago:

This one's from Hofeling, yesterday, and I like the headline and that he indexed it. It's a bit longer and appears to be a different version though I haven't looked at them side by side yet. Not sure about Castella's theory, but I have some more vids on it coming.
Hofeling:
"Here are the key points from the transcript with timestamps:

- 0:04: The 8mm home movie by Abraham Zapruder is a key piece of evidence in JFK's assassination, heavily scrutinized by the Warren Commission.

- 1:24: Bystanders on the lawn seem to react as if the limousine has not passed, suggesting the background action may be out of sync with the limousine.

- 3:00: Dr. John Costella argues that the Stemmons Freeway sign in the film does not align properly with other objects, indicating it may be fabricated to cover retimed footage.

- 5:23: The actions and sizes of bystanders appear inconsistent, suggesting the background layer was resized separately, and motion blur inconsistencies provide evidence of background alteration.

- 8:30: Significant inconsistencies in the limousine's speed and passenger movements point to retimed footage, which could hide the fact that the limousine slowed or stopped during the shooting.

Somewhere in my bookmarks I have an article with links to all the 2003 Z symposium presentations in playlists, that I'll be able to download if I can find it.
