So I don't see this as positive at all.
There is a comment on there from one of the contributors saying that Shn Faye has said about prisons they don't "expect" that self id will change anything and so that's all fine.
Erm.... Well one person with no specialist knowledge thinks something will probably be fine, so we can all down tools and go home 
Actually what that means is, don't worry your pretty heads about that ladies, the men in charge will make sure everything is AOK.
