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

It seems that Jackie did move around some in that vehicle. ON the right she was closer to the door where it was comfortable for her to rest her hand on the ledge. But could she do that comfortably on the left? I don't think so. 

Notice that she is more internal to Nellie. 

So, was she even close enough in this picture below to get her hand behind the window? 

I doubt it. And considering how much farther away her left forearm was from the camera, why does it loom as large as JFK's?
