So you came across a rehabilitation facility (as differentiated from a prison) in Austria- who has a much more progressive view of incarceration than the US to begin with, and for which no violent criminals would be housed in- and are representing all prison conditions to be like this. Is that the point you're making? Because that seems to be your point, that people who commit barbaric acts will wind up in a facility like this, so we better just brutalize them instead.
Most of the prisoners in Bastoy (Norway) were convicted of violent offenses, such as murder or rape. I don't think it is a nice idea to provide such people with 5-star facilities inside the prison. If I had the power, then I'll ship them either to the White Swan or to the Black Dolphin in Russia.
I suppose it depends what the intent of prison is. If it's to reform people and have them be functioning members of society when they're released, I think Bastoy is shows some promise.
