Well, look here: the State Department just published its 2009 Country Reports on Human Rights. And there's even a report for China. You should read it. It mentions well-known cases like that of Liu Xiaobo, who was sentenced to 11 years in prison on Christmas Day just because he wrote something the government didn't like. It also mentions Gao Zhisheng. He's a human rights lawyer. Or at least, he was: He disappeared over a year ago, while in police custody, and the government won't say what happened to him. His family escaped from China on foot - they're safely in the United States now. But where is he?
I'm willing to bet that the person who researched and wrote the first draft of this report had nightmares about Gao Zhisheng.
In fact, I'm sure of it.
