City of God?

Rating: 8/10 (10 January 2014)

Why was this area of Rio called "City of God?" I don't get it. Its obvious god never walked these streets or protected the children that lived there. It sure gives you another look at Rio. One that we don't see on the vacation brochures. Its very hard to imagine young children carrying guns and shooting other children in order to be part of a gang. It was a real eye-opener. And I'd like to know if the children in the movie were filmed live or if they were all actors? Did this movie receive any awards the year it was released?
I know the movie gives Rio a bad image - but, I cant help thinking its doubtful I'll ever visit there for a vacation.
