The 'Snow Revolution' against Vladimir Putin

Starting in late 2011, tens of thousands of protestors took to the streets to try to stop what they saw as a power grab by Russian leader Vladimir Putin. The demonstrators wanted to stop what they considered a fraudulent parliamentary election and a surprise announcement that Putin would run for president for a third time. The movement was not successful, but analysts say it worried the Russian leader so much that he launched a crackdown on dissent that has lasted to this day. Rachel Naylor talks to Russian rock journalist, Artemy Troitsky, who composed a song that became an anthem of what was sometimes called the "Snow Revolution".
