Steven D. Levitt of the Freakonomics book and blog asks the question that dare not speak its name: If al Qaeda really wants to destroy our way of life, why don't they launch a series of small, simultaneous, coordinated sniper attacks on public spaces all across the country? That this has never happened—even after the D.C. sniper showed everyone how easy and incredibly damaging such attacks would be—would seem to say a lot about al Qaeda's actual operational capacity and/or goals.
