Quotes

 * If you want to know what people are worried about look at what they spend their money on. If you’re afraid of burglars you buy a burglar alarm. What are the Chinese spending their money on? We’re told from Chinese figures they’re spending on the People's Armed Police, the internal security force is about as big as they’re spending on the regular military. This whole great firewall of Chinese, this whole massive effort to control the internet, this effort to use modern information technology not to disseminate information, empowering individuals, but to make people think what you want them to think and to monitor their behavior so that you can isolate and suppress them. That’s because this is a regime which is fundamentally afraid of its own people. And it’s fundamentally hostile to them.
