8:30 A.M., May 21. Tori Amos' Black Dove (January) in the headphones. Twenty-four hours ago, a 15-year-old walked into a high school twenty minutes from my house and shot six other students. One month after the shootings in Colorado, every conceivable easy culprit has been aired, it would seem - black trench coats, Goth music, video games, the Internet, the fact that there are enough guns in America to arm every adult citizen. But maybe, just maybe, we could look at the fact of a society in which people have to work so much that they never see their kids, in which difference of any sort is looked on with suspicion, and in which, for all the empty hand-wringing by politicians about why these white kids keep killing each other, we're still taught conflict resolution at the point of a cruise missile.
