@matigo I don't think they will, for the foreseeable future.
- The police are power-hungry, heavy-handed, emotionally driven, and groupthink-afflicted. The entrance requirement, academically, is astoundingly lenient: you barely need to have finished secondary school. Their training doesn't really involve any sort of "keep calm", based on their actions in recent times, so, like that worst stereotype of the US cop, they have come to rely on their weapons and basic intimidation. (This evening, a man was arrested after being searched: police found a green chopping board in his bag.)
- The principal slogan for the protestors is "Five demands, not one less" which is hardly conducive to healthy negotiation, since that involves compromise of some sort from both sides.
- China has a history of very bloody revolutions and, to my knowledge, relatively few peaceful ones, at least since Mao.
