When I look at the photograph of Jared Loughner, the Tucson killer, I see a crazy person: the wild eyes, the cruel grin from someone who murdered nine people, including a child. How do we understand this behavior? Psychologists know a lot about aggression and violence. Much of that knowledge is presented in the book Human Aggression and Violence: Causes, Manifestations, and Consequences that Alan Kazdin has reviewed. In Tucson the manifestations and consequences were clear, but on reading Kazdin's review, I doubt that psychologists could reach any consensus on causes, or could they? Even if that happened, would it matter to the public?
