Well I can't exactly quote CNN for you to show you the counter to Western propaganda, can I? Tell me a "legit source" that isn't skewed by Western media.
All legit sources are members in a conspiracy to discredit China. Only the studious journalists at prolewiki and johnmenadue dot com will tell you the real facts.
But, ultimately, there's not going to be a new York Times article saying that China didn't slaughter people for no reason because that's against their goals as Western journalists. I guess you'd just have to believe that the news lies about things. But I guess you believe that the news always tells the truth and that they're infallible.
That video literally shows the people that're rioting and throwing Molotovs at military vehicles. This is also outside the square. Tankman is also the day before the riots and the tanks are leaving the square, not going into it.
