Carole Cadwaller / The Observer: "Pussy Riot aren't just the coolest revolutionaries you're ever likely to meet. They're also the nicest. They're the daughters that any parent would be proud to have. Smart, funny, sensitive, not afraid to stand up for their beliefs. One of them makes a point of telling me how "kindness" is an important part of their ideology. They have also done more to expose the moral bankruptcy of the Putin regime than probably anybody else. No politician, nor journalist, nor opposition figure, nor public personality has created quite this much fuss. Nor sparked such potentially significant debate. The most amazing thing of all, perhaps – more amazing even than calling themselves feminists in the land women's rights forgot – is that they've done it with art."
