Jerome Corsi has at least attempted to. He claims that forms were NOT pre-numbered, that the certificates were stamped at the moment processed; and that therefore the non-sequential issue is a smoking gun.
At the moment, I don't know what evidence he has of numbering at processing time. Doing things in that way seems counterintuitive to me. I would frankly more expect pre-printed forms. It's simpler.
I also, to be honest, don't have 100% confidence in the quality of Corsi's research. Why? Because he seems to be prominently behind the $2 million spent claim, which I haven't been able to find any real evidence to support.
So for this particular issue, a lot hinges on whether Corsi has some real hard evidence of stamping at processing time. Hopefully we'll see soon what he's got.
Some on here think stamping the number on at processing time is already established. I don't know, but for such an important document, pre-numbered forms would have given them better control in 1961 than sending out identical blank forms to be numbered once actually used to record a birth.
Lots more room for fraud with identical blank forms than with pre-numbered forms (and not necessarily related to an Obama BC on that).
