Libya has long used the six medical workers as bargaining chips and political pawns in its international relations. Right until the final hour of their release, Libya haggled to win further concessions to improve its political and trade ties with the EU.That's from the blog of Declan Butler, a senior reporter at Nature who led the way in raising awareness of the case. He includes a comprehensive list of recent stories on the subject. Here's a question for those of you who have followed the case. Despite the medical evidence, diplomacy rather than science carried the day. Granted that we may not know all the messy details of this affair for a while or the motivations of the key figures, how big a role do you think scientists played in pressuring the Libyans to release the medics? Did they do the right thing by speaking out on behalf of human rights and standards of evidence?
