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

I guess you're writing rhetorically when you try to give me orders, Backes? Like that's ever going to affect me. 

And no, Backes. I didn't mean contiguous. Contiguous means close together as to be touching. "Italy and Switzerland are contiguous countries," for example.

I meant continuous, meaning that the line of their raised arms are continuous with each other, as in here:

Would her raised left arm form a continuous line with his raised right arm? 

First, notice how similar those images of Kennedy are.

As I said, on the left the photographer had to swing a little more towards profile but not much. 

Their right arms look exactly the same. You can see the seam of the shoulder on both and the arm coming down. On the right, she has her head rotated to her left, whereas we're not seeing that in the magazine pic.  But, it's just a head rotation; she doesn't appear to be doing anything different with her shoulders. And on the right, she's got her hand resting probably on the chrome plate which we can't see because of the view that it is. On the left, her hand is in the air outside the window, her fingers exceeding the chrome molding. From that perspective, it has to be her left arm in the magazine pic because her right arm couldn't reach that far, and it would turn her completely around. So theoretically, it has to be her left arm. There is just no way it could be her right. 

But, what would we have to do to this pic to make it conform with the magazine pic?

 The main thing would be to raise her forearm up. And granted, we have to try it with the left for the reason that we know there is no way, no how, she could have gotten her right hand behind that glass.

This isn't perfectly right, but it's reasonable. We know that Jackie never raised her upper arm significantly. She waved by bending the elbow and raising her forearm. I don't know of any exceptions to that, and I'll let my enemies look for such. But that is about how she waved. Now, how could you possibly get a straight CONTINUOUS line like what we see below from her doing what we see above with her left arm?

 You couldn't. And why does her forearm loom as large as his if it's on the opposite side of the car, much farther from the camera?
