Yes, on both accounts. The USN would not have approved the issuance of the PH without that documentation. It has to be in Kerry's file. I say that as a former naval officer. The data was obviously fabricated not only based on Hibbard's statements, but also, those of Adm. William Schachte who was on the skimmer with Kerry and was the senior officer present and Dr. Letson who treated him.
Kerry has not authorized the release of that information because it could probably raise more questions than it would answer.
Assuming that to be the case and also assuming, I'm afraid, that the information wasn't somehow purged from Kerry's records, barring full public disclosure with the execution of a new SF 180 by Kerry (which ain't gonna happen), there appears to be only one avenue of approach open to possibly shedding some light on this issue, at least in the short term...interrogatories of the 3 recipients named in Kerry's SF 180 release.
This would have to be done quite publicly by a reporter, news organization or media entity whose query could withstand the ensuing avalanche of opprobrium from Kerry and the left. Michael Dobbs of the Washington Post or Tim Russert come immediately to mind but I doubt a "Profiles in Courage" award will be headed their way anytime soon in that regard. However, Jeff Beatty's campaign for Kerry's senate seat might offer an opportunity for some Massachusetts media entity to pick up the gauntlet. Howie Carr, call your office.
