Reuters"The marches began this month with an isolated protest in Sao Paulo against a small increase in bus and subway fares. The demonstrations initially drew the scorn of many middle-class Brazilians after protesters vandalized storefronts, subway stations and buses on one of the city's main avenues. The movement quickly gained support and spread to other cities as police used heavy-handed tactics to quell the demonstrations. The biggest crackdown happened on Thursday in Sao Paulo when police fired rubber bullets and tear gas in clashes that injured more than 100 people, including 15 journalists, some of whom said they were deliberately targeted. Other common grievances at Monday's marches included corruption and the inadequate and overcrowded public transportation networks that Brazilians cope with daily. POLICE SHOW RESTRAINT The harsh police reaction to last week's protests touched a nerve in Brazil, which endured two decades of political repression under a military dictatorship that ended in 1985."
