i don't think border control guards have the right to tear apart a passport, especially not the one of a foreign citizen! this is not just an "incident" this is a serious misuse of their power! I'm very impressed by Hovis reaction, especially when he points out that this should not affect peoples view on the russian entry nor the singer. And I totally agree with him.
On the other hand - to all those who over the past months and years tried desperately to argue that gay people do not have a more difficult life in russia than in any other country (esp western ones), this kind of thing would definitly NOT happen at the airport in Munich, London, Paris, Rome, Madrid etc.... And please spear us the ridiculous "oh that's just western propaganda" pseudo-argument!
