This is basic Geopolitics 101:
When something 'bad' or unseemly happens in your rival's nation, you play it up for all its worth as proof of their wrong-headed ways and your superiority.
Ferguson is a blip of a blip on the radar screen of events in the geopolitical stage between the US and its rivals.
There's an immense amount of irony, of course, of Russia complaining about "racism", and North Korea worried about 'human rights', which is roughly the equivalent of the SS expressing concern over racial and religious freedom abroad, but the propaganda machines will roll forward either way.
It's all a show, it's pure schadenfreude at its finest, and it will be forgotten on the world stage in a few weeks.
