A hundred people demonstrated in Paris on Saturday calling for the release of American-Canadian anti-whaling activist and founder of Sea Shepherd Paul Watson, whose extradition is being requested by Japan following his arrest in Greenland last July. "This extradition is very serious because Paul Watson has never killed anyone," explains Michel Blazy, local group coordinator for Sea Shepherd Paris. Watson was arrested on July 21 in Greenland, an autonomous Danish territory, over a 2010 altercation with Japanese whaling ships. A custody hearing will be held in Greenland on August 15, pending a Danish decision on the extradition request. IMAGES AND SOUNDBITES
