I want this petition because I believe that Julian Assange must be free and not prosecuted. Imprisoning Julian Assange would mean imprisoning all the ones who try to reveal the truth. 
Censorship means dictatorship, not democracy. If United States and Europe are democracies they can't persecute mr. Assange or everyone trying to make people conscient of what happens in their own countries. This is a crusade to save the freedom of speech and information. 
If it's true that there is nothing wrong in what politicians do, they can't fear a single man or all those who want to say their meaning or inform with transparency.
