Ok. The way that you worded it sounded like you were say that Walt Brown was the expert in fingerprint identification.
Darby never analyzed a fingerprint and matched it to Wallace. He analyzed a photograph of a palm print and declared it a match to Wallace's fingerprint.
Actually Tim, Darby did analyze a left little fingerprint of Wallace's. The problem was, it was a plant. Author Barr McClellan along with another author named Harrison gave Darby an old fingerprint card and what they claimed was a latent print and have him analyze them. Of course he said it was a match. When he was told that the only latent print found was a palm print Darby knew he had been played. It was all just so McClellan and Harrison could write a book. That's what all this has turned in to. It is just so the CT buff authors can sell books. That is why people like Harold Weisberg fight so hard against authors like Bugliosi and Posner. It kills their book sells if too many people start believing Oswald acted alone. It is disgusting that they make so much money off of lies and the president's death.
