The Unidentified Male claim is unrelated to the Movement in the Window controversy.
On looking at the trial documents again today, I see that Geoffrey Rivlin, Q.C. did not question PC Myall about the movement in the window, even though it was Myall who actually saw it, not Bews. I just find that astonishing. What was the point of asking Bews if he had seen a 'trick of the light'? Bews saw nothing anyway.
