Man arrested after violent incident in Kongsberg; Norway

Most of the police there don't carry afaik, there would be a bit of time for someone to go on a rampage before the armed units turned up. Still a strange choice of weapon.

There still trying to figure if this is a lone wolf terror attack ,

Attacker was a local Norwegian who recently converted to Islam

The Norwegian report I read said he was ethnic Norwegian

Of course they are the actions of a sane person, he just has a different belief system, one where this is not just sane but the highest act a person can perform.

That doesn't make it right as far as I or you are concerned. You are looking at it through a purely modern European lens.

Reports say he is Danish, nothing about his religion.

DAnish mother, Norwegian father. Radicalised Muslim convert

It seems unjust because your looking at it with a view that the justice system should punish people rather than fix them. It's a fundamentally different philosophy.

A supporter of restorative justice could tell you that it's unjust that someone who realises the mistakes of their ways, accepts them, fixes their underlying issues, and is ready to contribute to society in a meaningful way is left to rot in a jail cell will no support just because you want to see them 'punished'.
