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

"Schaeffer provided no sources. He was just expressing his opinion that the Altgens photo was delayed."  Professor James Norwood

No, James. Roy Schaeffer was not expressing his opinion; he was reporting his own personal experience. He worked at the Dayton Daily News, and he said that he, personally, received the Altgens6 photo-fax, which arrived at 7 AM on Saturday, November 23, and he observed immediately, from signs of masking and opaquing, that it had been altered.

It's not an opinion. It's a statement of fact. 

Now, if you want to dispute it, you can only do so by calling him a liar. 

If you want to do that, I can't stop you, but that's the only basis by which you can dispute what he said.
