To me its certainly plausible the info is real & birth certificate fake. If you remember the whole “birth certificate” thing was starting to grow legs again. Remember Trump was making noise about it. It’s easy to see how the “kiddie corps (You know those cocoa sipping pajama guys!) would panic slap something together and release it. I can see them reason that, ‘Computer document forensic analysis is esoteric enough and full of “experts” who will contradict each other, so releasing this will defuse the controversy.’ From my optic it did, it deflated public interest in it. So it worked!
I am not saying that’s what happened. I am just saying I can make a case that its plausible.
If the info on it was factual, there would be no need to forge a document. There were threads taking it apart. There is no doubt it is computer generated, not a photograph of a real document.
