"1) Oswald, conveniently, places the bag in the car with Buell still inside the residence."
Randle used her xray vision to see him do it.
Seriously?
In the photo from Randles position from inside the garage we can easily see the specular highlights of the car beyond, the wall isn't solid but is made up of slats. The Commission exhibit that is posted is no better than a photocopy, was taken at a different time of day with what looks like a flash and even if we had a pristine original the contrast range of a camera photo is nowhere near that of the human eye.
As the camera which is level with the car bonnet approaches Frazier's car we can see through the slats that are below the horizontal plane of the camera and we know that Randle was looking down on the roof of the car in the garage so she would have a clear view of Frazier's car.
Like the slatted wall, the same principle can be observed with venetian blinds. In these more modern images the outside objects can be clearly made out and with the evidence we have, Randle's view would be similar.
Frazier reinforces his sister's testimony because he sees the package on the back seat of his car, SlaM DunK!
Mr. BALL - All right. When you got in the car did you say anything to him or did he say anything to you?
Mr. FRAZIER - Let's see, when I got in the car I have a kind of habit of glancing over my shoulder and so at that time I noticed there was a package laying on the back seat, I didn't pay too much attention and I said, "What's the package, Lee?"
And he said, "Curtain rods," and I said, "Oh, yes, you told me you was going to bring some today."
That is the reason, the main reason he was going over there that Thursday afternoon when he was to bring back some curtain rods, so I didn't think any more about it when he told me that. JohnM
