You do not need to get a waiver from Hawaii in order to get a computer generated birth certificate. Obama says he asked for a waiver to get a photocopy of his original birth certificate. Hawaii granted his request and say they gave him photocopies. What you see on the White House website is not a scanned photocopy. It's very simple. The minutia of all the different ways the document was forged are secondary.
The only evidence you have cited for your argument that the document was "computer generated" is the pixellation and . I'm pointing out that there is another version of the document, also released on the same day, that does not have the inconsistent pixellation and layering:
If, as you assert, Dunham's signature was computer-generated (as opposed to being an actual ink-pen signature), how could there be a version of the document that has an ink-pen signature for Dunham?
