Mass murderer Breivik will avoid prison?

"But under Norwegian law, he cannot be sentenced to prison or preventive detention but can be confined to a mental hospital for the rest of his life, police said."
I seriously doubt they are going to go soft on him, they will give him the worst sentence they possibly can. Even hippies that think everyone deserves a second chance will not be very forgiving of someone like this.

Looks like I read it wrong. But 1 killer in Finland was concluded to be suffering from the same psychotic state as Breivik and because the doctors said he had recovered from it they set him free.
