Brazil------A Safe Country for an Olympics Games?

Brazil got the chance to hold 2016 Olympics Games not long ago.Now the country has been a target of news all over the world.But I found no good news for the country which is famous for its football and Samba. Its safety problems are more and more worry people in the planet.Maybe Brazilians are worried too.Brazilian government should take more actions now because it's not only for Brazil,but also for countries with a situation like Brazil.You know,some countries like Brazil also want to hold the Games.

But right here I have to list a typical incident that happened in Brazil recently!
