Tell what is fake?
I could color photo copy a 100 dollar bill back it, take a picture of it, and you could not tell from the picture that it was fake. Though clearly it IS a fake.
You can’t prove much about any document from a PICTURE of it. You certainly can’t tell if it is real or fake. And REAL documents expert will tell you that. Hollywood could produce just about any document that they needed to and you would not be able to tell if it was fake with out an expert, and that expert would have to be actually holding the document to tell. Polarik might have gotten some things right, but he got a lot wrong as well, mostly because he isn’t a documents expert. He writes surveys and does Statistics.

You can certainly tell if it is fake, or at least misrepresented, either deliberately or accidentally.
For example, if someone posted a document date stamped 2007 and asserted the was ordered in 2001, we would surely know that the underlying facts are not as asserted.
That should sound vaguely familiar to you.
If 0bama released his original Selective Service Registration, and it just happened to be on a form the SSA didn't use until two years after he signed and dated it, well, we'd know that's a fake wouldn't we?
He did do that, you know...
