It's still a bit different, though. I hadn't heard of these incidents before, but when I read your comment (which would have been censored in China) I searched for "philadelphia 1985" and quickly found an old clip from Frontline reporting on the events (which would have been censored in China) on YouTube (where it would have been censored in China, setting aside that YouTube is blocked entirely). Wikipedia (which is blocked in China) also has an article (which would have been censored in China if not already blocked), saying that the police first evacuated the surrounding houses and there was a protracted gunfight before they bombed "a fortified, bunker-like cubicle on the roof". This is not quite comparable to the military killing thousands of unarmed protestors.
