It is beyond time to Pardon Julian Assange. Because speaking truth, is not a crime.
Secrecy is used when the broader public would oppose the plan or action. The more open governments are in general, the more their plans and actions have to fit with what the population demands. Because if they don't fit, they will be opposed.
When they are opposed, they are harder to implement. If they are harder to implement, they will not be implemented. Julian Assange.
