Indeed. That would be evidence he's full of it. But it's NOT evidence he's committed academic fraud. The point is, he explicitly stated that he constructed the document in PhotoShop. There was no secrecy.
If it was an excercize in making a document using a modern computer program, (Photoshop) what is the point?
The allegation is that the document was produced using a modern computer program (Microsoft Word). If his findings are that it could have been done with a typewriter, it is a false statement since he used a computer.
That is fraud.
