Human Rights Watch is very clear about the impact of the games on human rights:
IOC and World Leaders Fail to Challenge Great Leap Backward for Rights in China
Sophie Richardson, Asia advocacy director at HRW:
“The 2008 Beijing Games have put an end – once and for all – to the notion that these Olympics are a ‘force for good.’ The reality is that the Chinese government’s hosting of the Games has been a catalyst for abuses, leading to massive forced evictions, a surge in the arrest, detention, and harassment of critics, repeated violations of media freedom, and increased political repression.
Not a single world leader who attended the Games or members of the IOC seized the opportunity to challenge the Chinese government’s behavior in any meaningful way. Will anyone wonder, after the Games are over, why the Chinese government remains intransigent about human rights?”
