AFAIR: The cables have a few partial answers to your question: There is a centralized system that can give detainment orders. (supposedly a Blackbox to the People at least who follow its orders with boots on the ground) One day apparently it spat out 24k names. They managed to imprison about 9k the following day. Naturally the government know quite a few things about what you’re up to and this is a factor. Going to the mosque is a supposedly the easy way in. Not sure in what xinjiang city the mosques are still accessible. All I could find was locked down ones with all kinds of barricades and monitoring devices.. I would be surprised if there was in Xinjiang unlike eat china anyone left who would dare to go to a mosque. Some of the detainees are used by the state as force labor and leased out to companies. It’s speculated that this demand also can causes mass detainment.
