The trial of Anders Behring Breivik has ended in Norway with a walkout by families of victims in protest at his attempts to justify the massacre.

Seriously, whether he is insane or not they just need to lock him up permanently and keep him from harming others. He killed 77 people and injured hundreds more. His actions were premeditated, not reactionary spur of the moment self-defense in the way self-defense is understood and typically applied. In my opinion he has no case.
