I found found him.....
at 1:19- 1:21 he is standing two behind the man with the helmet on. John has on a floppy hat.
I think he walks behind and does not come to the mic.
It is a shame that the video has been edited and we never get to see this person throwing his medals.
However, we do know that John Kerry participated in the event and can get an idea of what these people were doing.
