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

Duncan is taking this as evidence of a tear. But is it?

Are you sure it's not just twisted and scrunched? When we look at him from the front, we don't see any tear.

Look at the margin all that you can see. Does it look ripped, severed anywhere? Let's look at it closer:

I said: Is the margin of that t-shirt ripped anywhere? Do you see a tear in the margin of that t-shirt? If you don't, you don't. What we see is a non-torn, non-severed, non-cut but wavy deformity to the margin which was the result of Oswald's habit of tugging on his t-shirt. And it is that tugging that caused the depression of the margin not anything that happened at the theater. I'll put an arrow where Oswald applied the force. 

You can clearly see where the force was applied. But, it didn't tear the margin. It was a gradual thing that stretched the margin without tearing it. 

Prediction: Just like bpete's stupid, idiotic idea that shirt fibers got on the rifle from a prior wearing of the shirt in which he handled the rifle, an idea which nobody said before bpete and nobody is likely to say after him, this idea that the vee in Oswald's t-shirt is all due to a tear is going to go nowhere. bpete is juvenile. He hasn't changed a bit since he was making rock n roll as as a teenager. Not a bit. Same adolescent fool.
