Anders Behring Breivik was declared sane and given a sentence of 21 years. That seems preposterous to me. He is 33 now so he would be 54 when he is released. I read that Norway has a maximum prison sentence of 21 years and, presumably, no way to make that 21 years for each murder.
Then I read that Breivik could also be sentenced to indefinite preventive detention after his sentence is over and I realize they are just screwing with us.
