The CCRC will need confessions from officers that they put Nevill's pyjama top on & then lifted him onto the coal scuttle. Prior to the photos being taken.
Doubtful.
I would imagine that all the CCRC have to do is decide if Boyces finding's about the burn marks are correct and irrefutable,then decide if this evidence points to a guilty Jeremy or a guilty Sheila.
No confession is really needed from the police,the evidence will talk for itself if accepted.
Anyway,lets just imagine for now that Boyces evidence is accepted ,how do you fit this into your JB scenario Adam?
