I think that the science of risk assessment has obviously improved greatly over the years. It's not a precise science.
You have to bear in mind it's not just a binary in/out decision that the Parole Board makes. It's what the conditions are that would make this release safe. Nobody is one hundred per cent or zero per cent one or the other—risky or not risky. I think the crafting of the conditions and the nature of the supervision are equally important.
