The Parole Board, as shown by the Rice and the Warboys case, is subject to regulator capture. They spend a lot of time with poor misunderstood criminals, who had hard childhoods and were stressed. Those poor misunderstood criminals, and legal aid, pay for psychologists to write reports in their favour (as happened in the Warboys case) and pay for lawyers to represent them (as happened in the Rice case). The victims, meanwhile, can fuck off: the Parole Board has no obligation to even tell them what is happening, never mind ask for their opinion.
Naive do-gooders can then virtue signal by competing with each other to show how forgiving and understanding they are, from the safety of anonymity, and slip out the news on Boxing Day or whenver they think they can get away with it.
The evidence, deliberation and conclusions are all secret and, when exposed to the disinfectant of sunlight, are shown to be bollocks: in the Warboys case, a 40 minute meeting had unreadable hand written notes, and the paid psychologists were able to overrule the prison psychologists who had actually worked with him. The court hearing in the Warboys case shows that the Parole Board just paid no attention to victims, no attention to the public, but couldn't wait - FORTY MINUTES, the meeting took - to release a serial rapist.
There's a simple solution to this: the Parole Board can be a public tribunal, with the evidence heard in public and subject to public scrutiny. They were convicted in public, they can be released in public.
