Yes, the Olympics in Rio de Janeiro are likely to be disastrous. The city is pretty much descended into lawlessness and corruption. The police there have already stated that it is not safe for people to come there to watch the games. I think it is likely that there will be news stories of tourists being kidnapped and killed.
The evidence points to complete disaster during the Rio Olympics. If we look at what has already happened, the multiple virus outbreaks, the corpses floating up on beaches, the government that went bankrupt, and the police not getting paid to do their job, the Rio Olympics' future does not appear too good.
It is only six weeks before the Games are set to begin. Based on the statement given by Francisco Dornelles, the acting governor of the state of Rio de Janeiro, to the Brazilian newspaper O Globo , the state has not yet received recently-approved federal funds to beef up security and transportation for the quadrennial competition. If things are not corrected sooner, it could prove to be a disaster.
No, the Rio Olympics will not be a disaster. There are many possible challenges for these Olympics including the Zika virus. However, Brazil has been working to combat potential problems and they should be commended for their efforts. The Olympics are a long-standing worldwide tradition that should be supported rather than slated for disaster.
