With all due respect to your expertise, what does this have to do with two certified paper copies of Obama's original birth certificate being flown from Hawaii to Washington D.C. in a lawyer's hands and then being presented in PDF format to the world as the real thing?
Methinks both the paper copies and PDF were generated from decades-old data rendered as I described. That explains the multiple data layers featuring inconsistent rendering styles.
“Birthers” are making a serious mistake in applying modern technical sensibilities to what amounts to ancient technology. They don’t know how document processing worked in the past, thus they don’t understand what they’re looking at and can only explain it as “conspiratorial”. Should this ever reach court, they risk a very embarrassing & effective legal smackdown as a result. (Of course, whenever I try to explain these facts about technology past, I get lambasted as an Obama sympathizer. Emotional abuse doesn’t change the facts to fit their beliefs.)
