The days following the awful events of Littleton, Colorado have been filled with wild attempts to affix blame to something, someone, or a combination of both in order to make sense of a senseless act. The cheap and easy scapegoats are guns, and their availability. They are also the wrong scapegoats.
Music is another target of misguided blame.
The real blame for Littleton, et al, is multi-staged. Of course, Harris and Klebold are primarily to blame for the killings. But it goes much deeper than that. Nothing they did shocked their elders, as nearly every teen tries to do. There was no one to judge their behavior, because no one is allowed to judge.
