Also, Lilygran if you look at prisoners in general, they will weigh up what will give them the best circumstances, as anyone would, and you would be surprised how many suddenly discover they have gone deaf (so can ignore officers), got a serious illness (that's a morning on the hospital wing), want compassionate leave (parent, sibling or offspring has died, not that they ever felt the need to find them on the outside), want to learn to cook (extra rations in the kitchen), want a cleaning job (go-between for passing on drugs) and so on. It's too complex to be able to sort in terms of religion, personal safety or motivation to change for the better. Each prisoner has to be carefully assessed to determine whether their needs are genuine, with prison officers assuming they aren't and probation officers assuming they are until they know differently.
