Amnesty International have warned that Brazils Olympic legacy is under threat because of the level of violence in the country. The human rights organisation claims security policies in place for this summers Games in Rio de Janeiro are ill-conceived and they have tabbed the city as one of the deadliest on Earth.A report into the organisation of this summers sporting spectacular showed a sharp increase in murders and human rights violations since Brazil hosted the 2014 Football World Cup, which saw a series of protests. Amnesty Internationals report says more than 100 people have been killed in Rio in 2016, and they have issued warnings that conditions in the citys favelas remain extremely dangerous.When Rio was awarded the 2016 Olympic Games in 2009, the authorities promised to improve security for all. Instead, we have seen 2,500 people killed by police since then in the city and very little justice, said Amnesty International Brazil Director Atila Roque.Brazil seems to have learned very little from the great mistakes it made over the years when it comes to public security. The policy of shoot first, ask questions later has placed Rio de Janeiro as one of the deadliest cities on earth.The countrys historic ill-conceived public security policies, coupled with the increasing human rights violations we have documented during major sports events and the lack of effective investigations, are a recipe for disaster.Brazilian authorities are not only failing to deliver the promised Olympic legacy of a safe country for all, but are also failing to ensure that law enforcement officials meet international law and standards on the use of force and firearms.Two months ahead of the Olympics, there is still time to put in place measures to mitigate the risk of human rights violations and establish accountability mechanisms for those found responsible for violating human rights.As the global sports community gathers in Rio in two months, the question remains: will the authorities respect and protect human rights and deliver the promised legacy of a safe city and country for all?
