Good point.
The test is not whether the electronic document, per se, passes muster. Rather, it's whether the facts the electronic document asserts match what the State of Hawaii "knows". If not, forgery is an incidental artifact. If so, forgery is impossible.
Of course, what the State of Hawaii knows might not be the truth. But that's a whole other question, for which world-class computer expert credentials are irrelevant.
Alvin Onaka was legally required to verify specifically - if he “knew” (that is, if there was legally-sufficient evidence to support the claims) that Barack Hussein Obama, II, male, was born on Aug 4, 1961 in Honolulu on the island of Oahu to Stanley Ann Dunham and Barack Hussein Obama.
He did not verify any of those things.
Hawaii does NOT “know” any of those facts. And Obama’s forgery was made to appear that they do know those facts. That is precisely why forgeries are made.
