The case of Pussy Riot, three young women sentenced last Friday to two years behind bars for performing a protest song in a Moscow cathedral, has drawn more attention than any Russian cause in at least a couple of decades. People who have never followed news from Russia have felt moved to speak up in support of Nadezhda Tolokonnikova, Maria Alyokhina and Yekaterina Samutsevich. I am sure that at least some members of the Russian leadership are now scratching their heads.
