Protests ahead of Chile's referendum: It's been one year since massive protests over inequality rocked the normally staid and ostensibly affluent country of Chile. To mark that anniversary this week, tens of thousands of protesters hit the streets again, in part to call for a "YES" vote in Sunday's upcoming referendum on whether to rewrite the country's constitution. But some of the demonstrators turned to violence and looting, setting the country on edge as the crucial vote looms. Replacing the country's current constitution — which dates from the days of Pinochet's dictatorship — was a key demand of last year's protesters, who say that it entrenches the country's dizzyingly high inequality by limiting the role of the state and constraining political choices. If the current protests continue through the weekend, authorities and street activists alike are concerned violence may deter some people from voting.
