@Gargron it's crazy to me that China thinks they'll be able to break the will of these people. You can kill the revolutionary but you can't kill the revolution.
I can't imagine being a police officer being asked to kill a civilian, but I guess if they are worried for their safety then I could see it from a self defense perspective. Philosophically, I'd be thinking long and hard why I was in that position before having to commit such acts.
