Jeff Widener, an American photographer with the Associated Press, won a pulitzer prize for that photo, precisely because it was a still image. He also took a video, but the video tends not to be shown, because it reveals that the man wasn't run over. Then you have the fact that all the US press corps showed up right as the protests took off, a lot of dark money from NGOs and western think tanks was floating around, and then deliberate conflation of the worker riots (in which PLA troops were lynched outside the square) being confused with the mostly peaceful events inside the square. Then you have that interview with the protest leader where she was crying and basically saying she was trying to provoke a massacre so that the protesters could be seen as martyrs. She got her wish, even if the massacres didn't actually occur, since that's how the west depicts those events. Then there the highly suspicious fact that nobody talks about the fact that you had many different types of protester simultaneously. Some were opposed to liberal reforms, privatization, etc, (the workers rioting outside the square) while other protesters wanted more of that stuff (the student protesters inside the square). Then you have some racist elements mixed in with the student protests I've heard, i.e. that there were some Chinese who were protesting because they didn't like the presence of African exchange students at their universities. I don't know how true that is, but I've heard it a few times.
