Maybe they want a big deal to be made of this. Then he produces the documents and his folks crow about everyone picking on Barry. The when something really significant is stumbled upon they can defuse it and say its more of the same. Just a guess.
Even if he has a legitimate Hawaiian BC that still doesn’t settle the Indonesian connection. When he came back there must be a record of it with immigration otherwise that could make him an illegal alien.
Like I said before, I think that the reason is something unimportant, like the name on his birth certificate is Barry, whatever his mother’s maiden name is, and that he adopted the the Barrack Obama after her divorce. He was registered in school in Indonesia, as Barry Soetoro. I think that he was still Barry in the Hawaiian prep school,too. I think that he just thought that Barrack Obama sounded more exotic and politically expedient.
