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

Above is the Squad room scene as it originally appeared in Three Shots That Changed America. I am saying that it is a reenactment of the original where all the figures you see, including the cops and Lovelady, are different. Even the big cop and Oswald have to be different because they never move right, and in the first version, they did. They may have kept the original background with the lockers and books that are stacked. This was done much later, and you have to realize how sophisticated "computer generated imagery" (CGI) is today. The movie "300" was made entirely with computer generated imagery. The actors did their work on a stage. 
It's almost unbelievable what they are capable of doing today. 

But below is the Squad room scene from Four Days in November, and this one was simple. It was all real footage except for the Lovelady figure being implanted into it. Everything in it and everyone else in it is real. Only he is fake. He was implanted into it. 

 If you compare the top file to the bottom one, you will realize that there is not a single matching frame between the two movies. NOT ONE FRAME matches between the two. Not one frame can be found in both movies. There isn't one instance in which you can take a frame from one and put it alongside the corresponding frame from the other and see that you have a matching pair, a duplication. You NEVER have a match. Nothing ever matches. Absolutely nothing. They are two completely, totally different films.
