How is an unarmed person violence? Genuinely, what violence were they engaging in if a bunch of liberal students burned them alive without dying? Look up the pictures, watch the videos, Chinese police are very different than the ones we (assuming you’re in a country that’s any degree of westernized) are used to. Think the old times type of dude with bright sticks directing traffic.
Cops under capital =/= peace officers under socialism. I very much wish a terrible fate to American cops while also recognizing that that isn’t the same thing as a cop protecting the revolution. We are capable of nuance here.
Furthermore, even if I were to concede the “the presence of authority is violence” point (side note, are you a libertarian? Not trying to dunk, just wish to understand where you are coming from) the first violence was from the protestors (who were led by a woman that straight up said she wanted people to die for propaganda purposes, it’s on video, it’s on YouTube). So if we can agree that the secondary aggressor has lesser culpability then even then the “violence” of trying to keep the peace was self defense.
Oh, and do you know what the inciting incident was? The initial core of the student movement was opposing liberalization. The protest hijacked by the anti communist mentioned above (who fled to America btw, wanted her followers to die for cynical reasons yet considered herself too important).
