"Breivik had no intention of tying ordinary and healthy friendships," the Correctional Services statement stated as quoted by VG. The Services suspected he was trying to send letters to people willing to use extreme violence and terror.
Breivik's lawyer Geir Lippestad told VG that the decision would be appealed in court, as he believes that "it is not legally tenable to censor letters without reviewing individual letters."
