Place the blame in the right place

I can't believe that instead of putting the blame on the obviously disturbed 22 year old, Jared Loughner, for shooting and injuring and killing 20 people in Arizona, in an AP article by Amanda Lee Myers and Pauline Arrillaga, it is suggested that "The assassination attempt left Americans questioning whether divisive politics had pushed the suspect over the edge." I don't know any Americans that are feeling politics are to blame, I think this is ridiculous! Put blame where blame should be. It's clear the man had some issues, he had made his own currency!
