FILE - In this Thursday, Sept. 26, 2013 file photo a police officer guards the US captain of the Greenpeace ship 'Arctic Sunrise', Peter Willcox in a cage in a court room in Murmansk, Russia. Russia’s parliament on Wednesday passed an amnesty bill that includes the 30-member crew of a Greenpeace ship detained after an Arctic protest, but it wasn’t immediately clear when or if the activists would be allowed to leave the country. The amnesty, which would also allow the release of members of the Pussy Riot punk band, has been largely viewed as the Kremlin’s attempt to soothe criticism of Russia’s human rights records ahead of the Winter Olympics in Sochi next year.
