Probably in order to maximize damage to his victims, Anders Behring Breivik had hoarded so-called "dum dum" bullets, i.e hollow bullets that expand when entering the target's body. These bullets are prohibited by just about every international convention regarding legitimate warfare! However, in order to minimize length of suffering in big game hunting, such bullets are allowed circulation and are, in fact, OBLIGATORY ammunition in Norway for those engaged in big game hunting (typically for hunting moose). The paradox in Norwegian weapons laws are that we have extremely restrictive laws with respect to hand guns (and smug US-bashers say how fortunate we are not to have permissive, "American" conditions on this issue). HOWEVER, when it comes to hunting, I believe we have very permissive laws, somewhat akin to Canadian regulations. Thus, Anders Behring Breivik has over the years hoarded some of the most deadly arsenal in circulation, precisely because he wanted MAXIMUM destruction, and minimizing the number of survivors.
