We have NOTHING that is proven.
And the best physical evidence we have suggests that the announcements did not come from the HDOH office in the first place, and that none of the microfilms that are in the libraries now are the ones that were in those libraries in 1961 - even though some with the wear and tear are clearly pretending to be the original microfilms from then.
I have in my possession the claim by the HDOH that they had no birth record for Virginia Sunahara AND a copy of the birth index page where her name is listed. Those are mutually-exclusive contradictory claims. That has to be explained. Duncan Sunahara is trying to get to the bottom of this but the HDOH is refusing to give him a photocopy of his sister’s original BC. They are breaking the law rather than show that to him. That should tell us something.
I have tried my level-best to avoid speculation about what happened. I have tried to focus all my attention on just the documents we actually have and whether they can be authentic. The physical evidence suggests that there are huge problems.
Without getting at the records we could be dealing with either. It wouldn't surprise me if we were also dealing with both. Lying and Incompetent seems a pretty apt description of government in general.
Either way, it's not a good foundation for proving something.
