A WaPo reporter disavowing what was published in their name.

China has never denied it or covered it up. The only thing they've rejected are Anglo-imperialist attempts to foment further discord like the statue in the OP here. The original protests were NED-funded too.

Wikileaks cables show that the US State Department knew what actually happened.

A leader of the protest acknowledges no protestors were killed.

So what did happen? A guy walked in front of a tank, which stopped for him and let him even climb on top without even being arrested (the video exists in full for you to confirm this). Imagine that happening at a 4th of July parade in amerikkka. CIA-fomented protestors killed unarmed members of the PLA sent in to disperse them. Again, imagine that happening in amerikkka.
