Demonstrators wave their country's national flag on Paulista Avenue where crowds gathered to celebrate the reversal of a fare hike on public transportation, in Sao Paulo, Brazil, Thursday, June 20, 2013. President Dilma Rousseff called an emergency meeting of her top Cabinet members for Friday morning, more than a week after the protests began. But the protests that raged across Brazil late Thursday and into Friday were spiked with violence as people vented anger over a litany of complaints, from high taxes to corruption to rising prices.
