I've been informed that Breivik has received all the letters that were sent to him, but he is currently not allowed to send any letters. He is trying to resolve this problem and will answer all letters as soon as possible.
I'll update this blog post as more information becomes available.
It appears the ban on outgoing letters was enacted about 3 weeks ago. The underlying reason was the publication of Breivik's letters on the Internet. A clear act of desperation by the system as the European population becomes increasingly restless and defiant.
Those who make peaceful revolution impossible will make violent revolution inevitable.
The ban is still in effect. The media has yet to write about this, but it's a well known pattern where they refuse to write about censorship by the system, like they failed to write about Breivik's wrists being chained to his belt to stop him from saluting. In fact, if the system could have gotten away with it they would have given Breivik a mask to stop him from smiling.
For those who've heard conflicting information, I'm 99% certain my information is correct.
