I don't remember saying anything about believing it (or not). What I was saying was that it was a first person eyewitness account of the event - not quite as vague as you were implying. As I said before, whether or not you (or anybody else) believe Shioda is another discussion.
Neither did I... I said that you (or anyone else) might
believe another's account without seeing it for yourself. It is that concept that makes it hearsay. Sorry for the confusion.
