Among young people who resort to violence, there exists an intense desire to regain control over their own lives. For years they've asked themselves who needed them, where they belonged, but they received no answers to those for them very important questions. In such circumstances, shooting people in public can give a wonderful feeling of power and self-confidence, because you become the one with the power to decide who lives and who dies. And then you accept the less heroic moment--dying between the checkout lines of a supermarket--into the bargain.
