You're right, it is a disgrace. And one that has wasted millions of dollars.
The only case the UK now has against Assange is that he broke his bail conditions when moving to the Ecuadorian Embassy. And those bail conditions were the ones imposed on him for the alleged rape case that has since been dropped. Even when Assange is finally allowed to walk free, he will still forever be a marked man.
It literally is just a crazy mad game of political chess. Lets hope it all ends soon and Assange can finally sip cocktails in the sun. I also hope he dumps a shit load of documents that exposes everything too when he's finally free.
Fingers crossed eh!
That is more than likely their biggest fear, what hasn't been released.
Time will tell buddy.
