No journalists on the ground found any indication of a mass casualty event on Tiananmen Square

ON Tiananmen Square. This is fascist-level wordplay. The same journalists found a massacre all around Tiananmen Square in the rest of Beijing.

no evidence that Chinese tanks actually killed anyone on 6/4

This is just a straight up lie. Lots of people were killed in Beijing. Just possibly not any within the tiny physical confines of Tiananmen Square itself.
