Image Analysis
From your CNN link:
Saying that the "Tiananmen Square massacre" killings actually happened in other parts of the city may be an important academic distinction, but it isn't a particularly stirring defense of the army's actions.
Let me be clear here, No one's denying skirmishes and bloodshed. But the way it is portrayed in the western media is actually far from the ground reality. Have a read at that btw even WikiLeaks provide evidence of fabrication by the US
thx, nice read!
