The woman in the clip didn't quite get it right. Breivik did plant bomb, but most of his killing was done on the island where the political summer camp was being held. In cold blood he shot young people, and when the fell, he went over to them and shot again to make sure that they were dead.
As to the American student who lauds an act of utter savagery, he may well be protected by the First Amendment, but should be kept under observation by the appropriate authority. His choice of language - assuming he really understood what he was saying - is capable of being understood as justifying the Nazi genocide.
The only comfort from this terrible event is that Breivik is likely to spend the rest of his life in an asylum. The young American's views are a slap in the face to the parents, siblings, families of all those who were so cruelly killed. He insults all of Norway, one of the most civilized places I have ever been. God help America, and the rest of us, if this young firebrand, or others like him, should eve aspire to political power.
