Although Lt. Bob Kerrey and Lt. John Kerry were both in VN at the same time, I would think that Adm. Zumwalt would know the difference between one man missing a leg and up for the CMH and another up for a Silver Star.
Interestingly enough, Kerrey spilled the beans without provocation that he killed civilians in VN in April, 2001 - a secret that he kept since '69.
bump!
