Nearly 100 activists—include a former deputy prime minister—were loaded into police vans in Moscow Sunday after staging a rally against a documentary that had aired on state TV. The film, Anatomy of a Protest, alleged that the demonstrations that rocked the Russian capital after Vladimir Putin won the presidency this month were partly made up of people who had been paid off—and fomented by the U.S. “This is a disgusting film, which is larded with lies,” M.P. Gennady Gudkov told the protesters Sunday. Indeed, the film’s footage is widely believed to be fake. But NTV, the state-controlled channel that aired the movie, is sticking to its guns: Anatomy will soon be rebroadcast.
