Where did Bamber agree? And as for Rivlin, in a case set up against JB, the police are hardly going to let through, any blatant evidence that someone was alive in the farmhouse. Rivlin should have dug and dug and been awkward. It's as if he didn't know how to. Instead, he just dothed his cap.
Bamber had a voice! Look at how sure of himself he was in the police interviews and at trial. If he felt that strongly about these matters that was the time to voice them not decades later when he's scraping the barrel.
Anthony Arlidge: You murdered your mother, father, sister and her 6 year old twin sons
Bamber: Thats for you to prove (and prove he did)
Bamber could have said: No Sir I did not. I was outside the farmhouse when PS Bewes, PC Myall and myself saw a figure move across a window. We also lights going on/off and curtains opening/closing.
