Self-confessed mass killer Anders Behring Breivik is more likely to be detained in a mental institute rather than prison, after psychiatrists in Norway declared him psychotic. How is this kind of assessment carried out?
Breivik, who admits killing 77 people and injuring 151 others in July, has been declared a paranoid schizophrenic after months of assessment.
A report by two court-appointed psychiatrists says he was psychotic at the time of the shootings and in subsequent interviews. Their findings must now be reviewed by a panel from the Norwegian Board of Forensic Medicine.
If approved, it could mean he is detained indefinitely in a psychiatric hospital and will not stand trial.
So how are such assessments made? And how accurate can they really be?
