Well, Mr. Firefox, everybody knows the problems of Rio de Janeiro, even the IOC, don't worry. It's truth, in the city are happening several attacks in the last days by drug dealers, but you forgot in mentioning just one point about this situation: This attacks are happening in retaliation by the ocupation of the police in the shanty towns (before occupied by drug dealers). The works of the police will no stop because of those attacks. The drug dealers are being rounded up by police day by day. The legacy of the olympics already began, even that Rio seems unsafe now. In 6 years those problems will not happen more. Will be just a problem of the past. Don't worry, the games of the XXXI Olympiad will be a great success.
