Further to that, I do believe that, yes, if there are three boxes for criteria that need to be checked and one of those boxes does not fit the criteria for a move or a rehabilitated prisoner, then the move is negated. If this prisoner is still a risk to society if he escapes prison, then he is not moved.
I believe there has to be more thorough testing. This prisoner has been in jail for 31 years. I think he knows the ins and outs and knows how to work the system and how to manipulate a test to show that he's going to play nice with another prisoner. That, to me, does not warrant a move.
If this is just a lateral move, as Anne Kelly has indicated, and from maximum to medium there's no difference and it's the same security, etc., then leave him in maximum security where he belongs.
There has to be a more thorough system, more questions asked and more ways that the system cannot be manipulated, and if any of those do not fit, then the prisoner is not moved and remains in the maximum security prison to which he was sentenced.
