What has any of the above got to do with the fact that a flake of blood was found within the silencer matching 4 of Sheila's blood groups which was capable of distingusing her blood groups from that of the other victims?
I believe Rob is saying in his WS, DB says he contacted SJ regarding the silencer.
Over a year later during his court testimony DB is saying 'somebody' did.
To Rob that points to Bamber's innocence.
It was probably AE, as she was in contact with Stan Jones.
