Cazatou,
I'm happy to agree with you, but surely that means that the failure (for whatever reason) to interview two vital witnesses means that the fullest picture is not known.
Therefore there is, perhaps, an element of doubt as to what happened.
Again, please don't think I am being disrespectful to those on the Board. Nor am I trying to twist your words to suit my purpose. I just see it as a straight forward omission of vital information.
My best, as always.
Brian
