Lazeyjayney around the world there are people being detained for many many years without charge or without trial, indeed in many countries the average length of pre-trial detention exceeds the length of post-trial detention and it happens because those countries are so poor their criminal justice systems simply cannot meet the costs of delivering a fair trial.
Want to get angry about human rights abuse get angry about that. Look up Penal Reform International or Amnesty and do something about it today.
Julian Assange had the opportunity to answer questions whilst not in custody in Sweden, chose not to do so, fled to Britain, had a bail hearing here and was granted it. Then made three attempts at judicial review (the judgments can all be read for free at BAILII if you want to see just how carefully the arguments he advanced regarding why the European Arrest Warrant should not be honoured in his specific case were scrutinised) before breaking his bail conditions leaving his friends to forfeit the bail money they had agreed to pay for him.
And then he calls himself the victim of a human rights abuse and claims the only reason he didn't answer questions in the first place was that he was being a gentleman.
It doesn't matter if he thinks he is under threat. The fact that he is currently living in the Ecuadorian embassy is not a human rights abuse because he is there voluntarily.
If he left the embassy and was extradited to Sweden that would not be a human rights abuse because he has had all the due process in England one person can reasonably have.
If Sweden detained him without trial or held an unfair trial or tortured him or killed him those would be human rights abuses.
If Sweden handed him over to the US authorities without a chance for him to challenge the extradition decision that would be a human rights abuse.
But until one of those things happens he cannot sit around carping about human rights abuses because all that has happened to him is he has been asked to answer some questions and consistently refused.
