I was thinking of Belmarsh which is, I suppose, the nearest to me. That certainly does look good but the inmates refer to it as "The Hellhouse of South London" because the regime is so harsh compared to prisons such as the Scrubs. However I'm no expert on prisons, NS and have never before heard of Point.
Totally agree that the Scandi method you outline seems the right way, sensible and forward thinking. However I understand why some people feel less sympathetic towards offenders even if I don't share their views. For all we know, they could have been a victim of violent crime at one time and experience like that is bound to make them biased.
Tbh I always tend to think that people, "Didn't really mean to do it", so would be useless working in a prison. I just feel it's wrong to write people off and imagine how devastated I'd be if I was written off. Let's face it, you don't have to commit a crime to be forgotten and discarded by society, could happen to any of us.
