The normal rules of evidence allow for access to official records, or other records for that matter, that could bear on the facts of a case. In this case, that access is being denied.
This sums it up:
“Obama released his birth certificate.” No, he didn’t.
“The short form is the same as the long form.” No, it’s not.
“Hawaii verified his birth certificate.” No, they didn’t.
“Hawaii won’t let him get his original certificate.” No, they will.
“It’s good enough for a passport”. No, not in all cases.
“Factcheck proved he was born in the US”. No, they didn’t.
“Election officials checked his background”. No, they didn’t.
“The Supreme Court ruled that he was born in the US.” No, they didn’t.
“It doesn’t matter, his mother was a citizen.” No, he didn’t meet the criteria of the law at that time.
“The law was changed and made retroactive”. No, it wasn’t.
“The short form is accepted in a court of law.” No, it can be rebutted with the source document and any amendments.
“The burden of proof is on you”. No, the burden of proof is on Obama and Sec. of States.
“Anyone raising this issue is a crazy conspiracy theorist”. No, they believe in the Constitution and realize that when someone spends hundreds of thousands of dollars to fight the release of a ten dollar document, he is hiding something.
“Tough luck, he won, get over it”.
