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

The Wizard found something really interesting, that Jack Ruby was upset when he was told that he was standing behind Detective Harrison, as shown in the film.

So, that's supposed to be Ruby in the sunglasses on the right. And in front of him, barely visible, is a taller man, Blackie Harrison. So, it appears that "Ruby" was behind the left shoulder of Harrison. 

 Lieutenant REVILL. I asked him about Detective Harrison. The films showed that Ruby was standing at Harrison's shoulder.
    Mr. HUBERT. What did he say about that? 
    Lieutenant REVILL. He became very upset.
    Mr. HUBERT. Did--describe how he was upset?
    Lieutenant REVILL. This is when he said--well, he got real angry at me and cussed me and told me----
    Mr. HUBERT. Ruby did?
    Lieutenant REVILL. Oh, yes; told me I was a hatchet man and trying to get the man's job.
    Mr. HUBERT. When he said you were trying to get the man's job, that is Harrison's job?
    Lieutenant REVILL. He meant Harrison's job…

Mr. HUBERT. But the mention of Harrison, apparently is the thing that set----
    Lieutenant REVILL. Set him off, and I have never been satisfied, personally, with Harrison's statement. Of course, this is my personal opinion. 

Wait, wait, wait a second! Hold your friggin' horses! Why doesn't the testimony state whether Ruby was shown the film? Why, in the name of the Immaculate Mother of God, would anybody tell Jack Ruby that a film showed him to be somewhere and next to somebody without showing him the film so that he could see it himself and see whether it's him? 

For instance, if they told him that Detective Elmer Boyd led him around the police station, and he denied it, they could show him this picture:

Don't you think that would settle it in his mind? He would have to be pretty deranged not to recognize himself in that picture. So, did they actually show him this picture?

I have yet to find a single report that Jack Ruby was shown ANY images of himself in that garage. Read the testimony again and notice the glaring absence of any claim of showing Ruby the images.

Then, the other thing that the Wizard found is this statement by Fritz in which he acknowledged that Bookhout was a fixture at the LAPD, that he was in there much of the time. 

Mr. FRITZ….Mr. Bookhout is in my office most of every day and works with us in a lot of cases...

  Mr. FRITZ. Mr. Bookhout is in my office with the FBI. My books are all on the outside and they check my books as often as I do.
