Owen Matthews: Who really killed Boris Nemtsov?
No Hollywood director could have framed the grim scene better - or freighted it with more symbolism. On a drizzly Moscow night, a gunman follows Boris Nemtsov, a prominent political critic, and his girlfriend across a lonely bridge. Six shots are fired. As the victim lies bleeding, the domes of St. Basil’s Cathedral and the Kremlin tower behind him. The message is clear: So die all enemies of the regime.
