Does the birth certificate correlate with the hospital records? Are the Nordyke twins and Obama on some register at the hospital that corroborates the BC? I mean, you would think this would be more convincing proof than a document that can be forged.
So far no one has come forward with the information about what "they" did at the Board of Health when the decision was made to permanently digitize their birth records.
Ordinarily source documents like that would be kept a few years "just in case" then burned or turned into cellulose additive for soil conditioning.
Since the first thread on this topic I've suspected most of the folks looking into it have absolutely no idea how advanced data storage and retrieval has become, nor even how advanced it was even back in 1961.
Really good systems are invisible ~ the people using them, inputting data, pulling out reports, working with the system simply never encounter some process that doesn't look familiar. It'll be a key entry, a picture, a printout of some kind ~ even though in reality the system might even have some sort of superfast holographic memory unit somewhere.
