Better take another look, Bendalot.
The "bloke with the stethoscope" (see post 80) in Kelly's office video is visible over Kelly's right shoulder in the picture of them entering parliament . Over Kelly's left shoulder is Hood in his pilot shirt. In the office video, though, Hood has changed shirts.
The "bloke with the stethoscope" is visible in both pictures with his blue cap on and "stethoscope' around his neck.
Reading above, as you suggest, doesn't tell me why Hood changed shirts so where is it that "THAT QUESTION was answered." ?
