Fascinating stuff, ultimately about just treating fellow humans as humans, with kindness and respect.
There's no question that America's prisons are far too preoccupied with security and holding people than they do actual rehabilitation - my incarcerated friends in the US prison system tell me those exact things.
This short doco makes you question things. The exercise the Norwegian warden does with the US inmates was intriguing - a murderer wanting a couch, when I'm sure his victim probably just wants to breathe again.
Things sometimes feel a little strange when someone from one country starts judging how things are done in another country. Norway has a prison population of about 4,000 people, compared to the US prison population of some 2.3 million - so, uh, is it really a fair comparison? In some ways, I would say no. It would be a little like an Australian walking around the US bragging about their successful gun legislation.
Norwegians are different people to Americans, and what might work in one culture, may not work in another. In saying that, the culture of revenge and continued punishment needs to be addressed in many prisons throughout the world.
Side note: I wouldn't mind living in a Norwegian prison - food looked delicious and they get badass recording studios.
