First of all, this terrorist is on vacation having standards equalling a high-level resort... he just can't talk to people... the cost to taxpayers money is insane... this by itself is a question that could be discussed...
The main area of conflict is due to the total level of isolation, he has been in total isolation since the day of the attack, and the main reasoning for this is that this guy is so dangerous and also having supporters. Authorities must at any cost stop him from communicating any sort of messages to these his supporters.
I think I remember that he got love letters and proposal for marriage via mail and so on, I think there's still quite a lot of supporters, for some reason it was an overweight of Swedish nationality, at least it's what media claimed for.
I am a strong supporter of the authorities's strong position in this case, I think it's the general opinion in the country too; and I hope it will be the same way forwards on. Remember, mostly all of the 77 persons killed in the insane shooting were members of the Youth division of the Labour Party, by far the largest Norwegian political party.
His time may, hopefully, never be out... how can he be let out into the free again?
This guy may not only be a threat to Norway, but possibly also on a wider geographical level, so he better be kept under the lid!
He's convicted to a special sort of custody, that as far as I understand will always be susceptible to re-evaluation when the time expires; If at that time he is evaluated to be a security risk, this time can be extended; and this can go on indefinitely.
Theoretically he may be out again, but hopefully not.
This is the one out of two times for the last 20 years that I can remember the Norwegian general public claiming that the death penalty would be justifiable (but of course we don't have death penalty). From another point of view it's probably more of a punishment to sit in a jail for the rest of your life.
