You can't have 12 originals handed to each jury member. There was not an original document with another document copied on its reverse.
--------------------------------
The truth is there was nothing on the reverse of the 4:02am, log from the scene - but a copy of the phone message log timed at 3:26am, was photocopied onto the reverse of the former, and stamped by the official crown court stamp as though both logs had been disclosed but we now know that even the prosecution confirm that they knew nothing about the 3:26am, log, at the time of the trial - so, where does that leave your theory?
The jury never got to see the photocopy details of the 3:26am, phone message log details, nobody did, it was not an official exhibit - you need an original document to make it an exhibit at crown court, and since no original was disclosed or produced, a photocopy would not suffice without there having been legal argument...
Phone log details timed at 3:26am, amount to a forgery if they were copied onto the reverse of another log, and someone is / was claiming the copy to be an original, when it clearly was / is not...
