A demonstrator wearing a Guy Fawkes mask holds a banner during a protest at the Portuguese parliament as part of the United for Global Change movement in Lisbon October 15, 2011. Demonstrators rallied on Saturday across the world to accuse bankers and politicians of wrecking economies, but only in Rome did the global “day of rage” erupt into violence. Galvanized by the Occupy Wall Street movement, the protests began in New Zealand, rippled east to Europe and were expected to return to their starting point in New York. Demonstrations touched most European capitals and other cities. REUTERS/Rafael Marchante (PORTUGAL – Tags: BUSINESS POLITICS CIVIL UNREST TPX IMAGES OF THE DAY)
