The Volgograd bombings may have moved the world's focus on the Sochi Winter Olympics onto security matters - but after the terror attacks, how can Russia track down the guilty, and keep them away from the games? Lucy Ash is in Sochi, witnessing - and following - the squads of uniformed Cossacks who are now back on its streets charged with detecting and removing 'undesirables'.
