21 years is the max. He was ordered to serve a minimum of 10 years with credit given for the time he's been in prison since the attack. Of course that will depend on evaluations given to determine if he's still a threat.

I doubt he ever gets out though… at least I hope he doesn't.

An initial team of psychiatrists found Breivik to be paranoid and schizophrenic, following 36 hours of interviews.

However, a second pair of experts found he was not psychotic at the time of the attacks, does not suffer from a psychiatric condition and is not mentally challenged.

Their report said there is a "high risk for repeated violent actions."
