A woman takes part in the "Marcha das Vagabundas" (Slutwalk) protest in Sao Paulo Jun 4, 2011. The demonstrators are protesting sexism, rape and sexual crimes following similar recent demonstrations in Canada where a Toronto policeman was quoted saying "women should avoid dressing like sluts in order not to be victimized". The banner reads "The male chauvinism kills". REUTERS/Nacho Doce (BRAZIL - Tags: CIVIL UNREST SOCIETY)
