I regard this author as of one of the best independent journalists that the US has. They are a rare breed, and because of this they can only be accessed through alternative sources on the Web.
In this piece he provides an in-depth--and I mean in-depth--analysis of this phenomenon of right wing assassins and wannabe heroes such as Breivik and Jared Lee Loughner. He clearly explains the cultural context that produces such people: a cultural context created by the close cooperation between Hollywood and the Pentagon to insert ruling class values and war propaganda into the minds of ordinary people, especially young people.
There is so much material here that I have some questions about its length for the internet. I think he has content for several separate articles. Most internet surfers are unable to stay with an article of this length. But, on other hand, it contains so much excellent material. I particularly recommend RT's 4:15m video critique of the movie, "Captain America" which he links to in the article.
