I just read that the gunman was a member of a defunct extreme right-wing group, but i think it could be one of 3 at the moment. Muslims, Nazis or Mossad.
Going by their (Norway) support for Palestine, seems odd the Moslems would target them? Yet they have troops in Afghanistan/Iraq, so a reason enough there i guess.
Fertilizer bombs were popular with PIRA so that could point to Libya, what with their past links with PIRA.
But then the blonde gunman targetting young lefties on that island points to the far right, but would they of not targetted a Mosque rather then a government building with the bomb?
A few twists and turns to come yet i think.
