Actually, I suspect that the Chinese are somewhat innocent.
I suspect that when more is known, this thing may turn out to be man-made and not a natural mutation of Coronavirus. And that it wasn't made by the Chinese, but introduced to their population by others. It seems they have had cases in military hospitals for a long time, and been pretty paralyzed with fear.
China has critters travelling pretty widely, and in many places they rub shoulders with al Quaida members.
....this could soooo easily be spread purposely in these densely populated and intersecting countries.
