Author of 'Dancing with the Devil in the City of God' Juliana Barbassa (@jbarbassa) discusses her book, and the lessons to be learned from Rio. 

When Rio first got the bid, "we felt like the world had noticed we were there," said Barbassa.  But "people only caught on a little bit later."

"It's a time to really rethink these games," said Barbassa. "Often the people who worked to bring them have their own agendas."
