The posted copy of the birth certificate is a ruse and wasted effort. You cannot with certainty authenticate a document from a photo or an scanned image. You need to authenticate the original document. To the best of my knowledge this has never been done and will likely never happen.
I ask the people that believe the birth certificate is real to answer the following question. If you had a chance to be a valuable historical document based on the way Obama’s BC was presented, would you spend your hard earned money as is just from looking at the photo or would you take the original document to have it authenticated by an expert?
HI got caught up in the “document automation” technology early on. It was decided that the paper copies would all be destroyed after a certifiable transfer to microfiche, then that to digital storage using what we consider primitive tech. Each stage was assured legal proof by lawyers and legislators.
Now, having had an initially unremarkable BC go thru that process of repeated duplication, transfer, and lossy compression, we are faced with an assured legal document of extreme value which cannot be proven beyond laws stating it is a sufficient copy legally constituting the original.
You’re right. There is no original which the Obama’s doctor and mother signed and which you could fondle to your satisfaction. Nonetheless, what we have is a legal, if anemic, representation of the original; insofar as it is a lossy copy which few understand the nuances of, it amounts to the original.
It’s like taking a raw 1/2-inch magnetic tape recording of Gershwin playing the piano, transferring that to vinyl and discarding the tape, then digitizing the record to 8kHz 8-bit .WAV and breaking the grooved medium, then converting to 64kbps .MP3, then burning a CD from that, then giving the CD to someone demanding the original. Then some fanatic listens to that CD, and freaks out that a metallic thump in the background, and other oddities, is proof it was made on a synthesizer, and won’t believe otherwise unless given the original tape. He is of course nuts because it is, for all practical purposes, the original - just copied badly several times - of Gershwin playing the piano. Just because the final rendering is poor doesn’t mean it isn’t proof Gershwin played the piano.
