I wouldn't even call this a clerical error. These things pile up in a 9 to 5 clerks in-box in roughly the order in which the kids were born as nurses wonder up and down the hall; the registrar then pulls them out beginning with the one on top, assigns it the next number in sequence, and proceeds to fill in whatever he/she must add. Thus little Baracky's paperwork was below several others' who were born later, but received earlier registration numbers.
I'm an agnostice about the BC, but I don't think this point is particularly important. I've just worked as a clerk in a military hospital and know how these things were done in 1970, anyway.
The numbers were not given at the hospitals. Janice Okubo, HDOH Communications Director, responded to a whole bunch of requestors by saying that the “date filed” is the date that the BC’s were numbered at the state HDOH office. Piles coming in or out make absolutely no difference, because whatever date they were numbered is the date that is put as the “date filed”.
And Obama’s was given a number on Aug 8th that was higher than the number the Nordyke girl was given on Aug 11th.
That just doesn’t jive. Piles don’t explain this mess.
