I think one of the reasons for the lack of security is simply that things like this are so rare in Norway. It simply wouldn't occour to anyone that a remote kid's camp would need guarding. To be honest, I doubt anyone here would either, and we have much more of a history of mass shootings. Remember that Swedish PM Olof Palme was assassinated back in the 80s walking down the street with his wife - no bodyguards. When was the last time a US President went out without protection? certainly not since the Antebellum. Scandanavia is a different world. I just hope that the horror of this does not change that society for the worse.
