Thanks for clarifying that. As you may surmise, I had slightly misinterpreted your response as meaning to assert you feel sure that Zullo does now have irrefutable evidence that Obama was Kenyan born. Sorry for that.
I can see your point that perhaps Shrimpton’s account could be fortified if he could demonstrate that he had some direct contact with the Kenyan birthplace memo or a had played a role in acquiring it.
It does seem as though some additional doubts could be raised about Shrimpton merely on the basis that Sharon Rondeau (Post & Email) has apparently now decided not to publish the interview with Shrimpton. (Birtherreport.com still intends to release the interview, however.)
