I might add, however, that there is an additional possibility for fraud in relation to the birth announcements, one that was suggested by Polarik:
It could be that the Obama birth announcements were created at a much later date and pasted over the original newspaper copies on microfilm or microfiche to make it appear as if they were within the original newspaper listings when in fact they were not.
I doubt it. A quick search on Worldcat reveals that there are multiple libraries around the country that have backissues of the Honolulu Advertiser on microfilm.
Are you telling me that someone went to the each of the dozens of libraries around the country and modified the microfilm? And that each and every one of them was doctored so well that it is undetectable?
Yeah, I suppose that's possible, just like it's possible Elvis is still alive or that the Feds staged the moon landing, but I it's a possibility so remote that no rational person would take it seriously.
