As morning dawned over Seattle on Nov. 30, 1999, leftist protesters surrounded the downtown Paramount Theatre. Using PVC pipes and other devices, some locked themselves to one another, blocking major intersections. By 8:30 a.m., protesters had shut down several city blocks. At 10 a.m., tens of thousands of union members assembled for a rally, followed by a march to downtown. Meanwhile, a small band of “Black Bloc” activists smashed storefronts belonging to multinational companies such as Nike.
