Every Sunday crowds of men, women, and children pack into Centenario Park in Buenos Aires to vent their spleens against banks, corrupt politicians, and judges, to demand justice for victims of political repression, and to organize pot-and-pan banging demonstrations (cacerolazos) and other audacious forms of political protest. They are distrustful of politicians, trade union leaders, government officials, big business... in short, anything that smells of the traditional power structure in this crisis-ridden country. They are not the black-clad anarchists one might imagine. They are middle-class professionals, merchants, office workers, housewives, students, those caught in the corralito--the severe banking restrictions imposed in December 2001 to stop a run on accounts--and voters who cast blank ballots to protest congressional by-elections in October 2001.
