The very fact that they are being kept secret creates doubt for me. If they weren't so important why keep them secret. Do you not have even a slight curiosity as to what is in those documents and wonder why they are so important that they must be kept secret? Especially when a man's freedom is at stake who may well be innocent?
I can see how it creates doubt,however there are items that must be kept "secret". I'm sure there are certain photos that should be withheld,never to see the light of day,in this case and many others I'm sure.
As for curiosity, I would imagine at an autopsy,photos are taken. I don't think withholding them under pii is necessarily wrong. In this particular case as an example,what would the production of an autopsy photo prove?
Therefore it would be handyto know what the list relates to.
