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

We don't know that anything got removed from Hargis because the fingerprint is an overlay.

We can see the white helmet despite the overlay, but we don't know that any data of his got removed. The smudge went on top of it; that's all.

But, with the other, there is no comparable smudge, and we are seeing background in the area where his arm should be that looks consistent with the background elsewhere. 

It is totally arbitrary and fanciful to claim that a fingerprint (which we can't see) removed his arm from the photo and replaced it with background that looks much like the rest of the picture. 

And note that you haven't submitted any example of this or any kind of demonstration, experiment, or test. It's just pure lip-flapping. 

But, don't worry: I'm sure Mark O'Blazney believes you. I'm sure he'll believe anything you say. He believed what you said last night, and he'll believe what you are saying now. But outside your minions, I don't think anybody gives a damn, and I certainly don't. 

The man's arm is missing. The man's chest is misshapen and totally out of character with himself. There is weird distortion on his face, neck, and shoulder. And the faint trace of motorcycle is just too eerie to be believed.

This kind of thing only happens in the JFK assassination; nowhere else. It is its own photographic world with its own photographic rules. It is a Bizarro World, built on blood, and sustained by lies.
