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

You see this picture, bpete? There is no tear in the margin of that shirt. There may be a hole in the left shoulder, but it's irrelevant because it has having no effect on the margin or the way the shirt is hanging, and that is what we are talking about. The vee-ish shape of Oswald's t-shirt was not the result of any tears because the margin is not torn. And if you want to claim it's torn in back where we can't see it, it's just an arbitrary assumption. But even if true, it has no effect on what the front of the shirt is doing. The vee is in the front, not the back. So forget about the back. 

There is no reason to think the vee we see here had anything to do with the fracas in the theater. None whatsoever. It was present when Oswald was standing in the doorway as Doorway Man.
