I thought that WorldNetDaily had a moment of decency when Bob Unruh wrote:
While there may be other challenges to the document’s authenticity that bear further scrutiny, it appears that the “layer argument” can be easily explained….
Tests on other PDF images produce an effect similar to the multiple layers extracted from Obama’s document.
Assuming that this statement is true, and I can verify that it is, what do we make of this article at WND, Online ‘birth certificate’ document ‘was changed’ also by Unruh?
A computer document expert who analyzed the online image of Barack Obama’s purported Certificate of Live Birth for WND confirmed there are anomalies inconsistent with a simple scanning process, and there is evidence it has been manipulated, but there’s no way to determine exactly what may have been modified.
In yet a third article, Hawaii detective charges: ‘Birth certificate’ a fraud, WND cites a named “expert” Ivan Zatkovich that contradicts the experts cited in the first article:
When a paper document is scanned on a scanner and saved as a PDF file it normally contains only a single layer of graphical information.
Having personally scanned a document with Adobe Acrobat, I know that layers are created and Zatkovich is full of it.
Of course WorldNetDaily is just fanning the controversy by reporting crank views, and not taking sides. It’s what they do.
