Someone is trying to kill Vladimir Kara-Murza. Someone is failing. The Russian journalist and democratic activist, a fierce critic of President Vladimir Putin, is soft-spoken but full of life as we sit chatting about politics in the atrium of Gates Hall. Kara-Murza is in town for a screening of his documentary Nemtsov, which tells the story of slain Russian opposition leader Boris Nemtsov, and in an interview with The Sun he explained the story behind the film, and what he hopes to impart on his audience. “Boris was the best of us… so they killed the strongest,” Kara-Murza says when asked about the brazen 2015 assassination of Nemtsov that occured just steps away from the Kremlin.
