A reasonable way to save Assange now would be to ask Max Von Sydow to visit the Ecuadorean Embassy and in a videotaped interview seek Julian’s version of the events he is accused of. Broadcast the interview world wide, and defy the Swedes to charge him. And if they do not charge him ask Britain to let him go. This will bring the Liberal Democrats to crisis, and their vote to a new low. They will then pressure Cameron to let him go. And he will.
Or it could be Sir Ken Branagh, the well-known Scandinavian inspector. Or Mads Mikkelsen. Or Scarlett Johanssen.
Pretty soon he would be laughed out of there.
Or perhaps you disagree.
