Breivik Gets 21 Years: And this is justice?

The Norweigian court has pronounced Breivik sane. I have no doubt that he is. He planned the whole thing meticulously. He's obsessive not insane. Breivik murdered 77 people. For that the court gives him just 21 years in prison - ensuring he serves a minimum of a piffling 10 years. Just what kind of justice is that?

Breivik is just 33 years old. He'll be back on the streets by, at the latest, the age of just 54 years.

It is indicative of the corruption of the modern mind that few countries have the moral spine, being no longer rooted in  Judeo-Christian ethics that most countries don't have the stomach for the death penalty.   Just how can the state guarantee that a murderous - by his own account - Breivik doesn't kill again?
