Re: Fake news?
As I recall that famous photo of the guy stopping the column of tanks was from after the protests had been crushed. Literally in a few cases, others were just shot. Which is why the guy was considered so brave. I think it was a spontaneous gesture of disgust/anger/defiance rather than a part of the protests.
There'd been a relatively peaceful stand-off with the military for days beforehand. I think the tanks rolled over a camp set up near the square, and there were still some people in the tents, and there may have been a few other incidents. But mostly protesters were shot or beaten. The journalists were all around Tiananmen Square, but the army had to fight its way through the whole city, to get to it. That has been a lot less well documented, given the government tried to suppress all the information it could.
