Q, I understand that the images he's viewed were difficult to assess, in that the ages of the girls/children/women in them were not easy to ascertain. If these extra alleged offences had been added to the initial accusations, the trial may have taken even longer to come to fruition, and knowledge of the viewing of images may have coloured the jury's judgment. I doubt if the application to the Attorney General will be successful, as the age of the man is a factor in the term allotted. Also, one would imagine the AG would hesitate before overturning a judge's decision unless there were very strong reasons to do so.
I've been present at quite a few Crown Court cases and I was always bemused by the mitigation part of the process. Defendants would plead that they had children, an aged mother, a good job, a disability etc. But one is led to wonder why they hadn't borne such things in mind when they considered breaking the law in the first place. I don't feel that Harris's sick wife or his own health are factors here.
