Finally the veil of naivety is lifting. Breivik is not a one off. There are tons of sickos out there, apparently, thousands. Thousands of sympathizers. And you need to do something to deter them from carrying out copycat attacks. 10 years (maybe 21, maybe more) years in a luxury prison away from non criminal society, don't cut it. Because they just replace outside society with prison society. You have an island prison community for fuck sake. Now I know you say its unlikely Breivik will go there, but come on, living on an island with other people is not a punishment or removed from society, people do it all the time.
