-I can't remember off-hand what his sentence was in years, but we have a form of sentencing for criminals being deemed extra dangerous to society called 'forvaring' (literally - 'safekeeping'). If sentenced under this statute, your case will be up for review by a board after a few years; if they find that the inmate is still likely to pose a danger to society, they'll just shrug and say 'tough luck', then schedule another review in a couple of years time. No worries. Breivik is not being released anytime soon.
