IMO, Pussy Riot is a pop culture intelligence propaganda OP. I have just seen far too many picture perfect reactionary scenarios with this group. This leads me to also conclude that certain related groups are trying to start a civil war in the US by leveraging racial tensions, and tensions against abusive police.
There's no doubt Pussy Riot is politically charged, even though it may all be just for ratings. Their staged events are certainly suspect. (ei. Like the one they staged last year, being whipped by Russian Cossacks.

As for civil war in the USA, I highly doubt that will ever happen. The most that will happen is greater public dissent, but like I said this could turn out to do more bad than good. Awareness and/or dissent may not cause the desired effect of change in government policy for the common good of the people, but may in fact create greater support for a stronger, more militarized police state. Most people (in the developed world) believe that their government and corporations would never do anything to harm them and (to them) anyone who believes anything to the contrary is deemed an extremist (the latest buzz word being equated to terrorists) or simply considered to be childish and immature, as in kids just being rebelious and worshipping music idols. In either case, police brutality is often seen as justified.
, that's thier level...
