We know what would be punishment for us, but are we sure we know what this guy would consider punishment?
After quickly reading through the 1500 pages of this Walters? manifesto, there is little I suspect that the perp would considered punishment as according to the document he considers himself perpetrating a martyrdom operation. The document contains very highly detailed counter intelligence and terrorism operations (probably plagerised from counter terrorism manuals being the son of a Norwegian diplomat.)
What is really disturbing about the document (assuming that the document is attributed to the perp), is the cultural symbolism appeal he makes to American right wingers/Christian fundamentalists, such as the so called 'Knights Templar' US marine uniform and SEAL emulation photo opportunity publicity shots. Hopefully this is the work of the lone nut or even a localised Norwegian/pan European cell of right wing extremists and not Alex Jones analysis of his accurate prediction of current events and is not a pysops operation perpetrated by even darker forces during the current looming financial crisis.
