Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Now Backes says that the films can't be spliced because splices are impossible. 

Backes, it doesn't matter if it's a splice of actual filmstock or if it's done digitally. I am using the word "splice" to indicate an outcome, a result -that two films were merged- not a physical process.

And there are other examples of it. For example, in Four Days in November, the Lovelady clip ends with the big cop in the white hat milling around that open supply room door with Oswald and the other cops. But then it jumps to the photographers being photographed by other photographers. 

But, in A Year Ago Today, from the same point it jumps to a cop examining Oswald's pistol:

So obviously, the films were edited differently, and who knows when they were edited differently. I'm calling it a "splice" but you can call it anything you want. The point is that frames were jimmied around in many different ways. There are no two versions of this footage that are the same. All the versions I've seen, and I've seen at least 5 or 6, are different. Every single one is distinct and unique in its exact content and sequence. That is what I am talking about, Backes. It doesn't matter how they did it; it only matters that they did it. And they most certainly did it.
