the only way we are going to get hold of the photo's is phyically steal them!!! but finding out where the photos are stored and security etc etc is the hard part unless you get inside info!
So having the photo of SC on the bed with June.
and the the photo of Shelia's footprint in RB blood pool! would prove alot!!
First her feet can't have been clear, unless they were cleaned before suicide or the police cleaned her feet to move her or Fuck ups with the first lot of swop/swap of the hands and feet!
and being on the bed and ending up on the floor is hard for a dead body/ies to do... the police said they never touched anything....

? lies
I would say too giving jeremy a whole taff life sentence is there to secure the photos & conviction etc... so if jeremy did serve his sentence before the Home sec upgraded it. what impact could JB had as a free man... into requesting all the photos then proving he didn't do it!!
