Where is Xu Zhiyong? Where, indeed?.

At around 5 A.M. on Wednesday, Chinese authorities visited the home of Xu Zhiyong, a prominent legal scholar and elected legislator in Beijing, and led him away. He has not been heard from again. Unless something changes, he is likely to stay away for a long time, with or without formal charges. Anyone with an interest in China, its economy, its place in the world, or the kind of future it will fashion, please take note: This is a big deal.
