> Actually, it's pretty ironic to have this discussion the same week that a convicted child sex offender was killed in a Norwegian prison after numerous warnings.

That an inmate gets killed in a Norwegian prison is extremely rare. As you mention it did happened this week, but the last time before that was in 1982 (according to http://frifagbevegelse.no/nffmagasinet/drapet-i-ringerike-fe... )
