When his own state, the local legal system and the media all turn on him? When he is forced to seek sanctuary in a foreign embassy for many years, surrounded by state security forces threatening to arrest him if he leaves? When the world's highest arbiter on the matter of his confinement, the United Nations Working Group on Arbitrary Detention, supports his case? When the state, legal authorities and the media ignore the ruling and continue to demand his arrest?
If this were China or Russia, at some point along this trajectory most of us would have been forced to concede that this was a clear case of political persecution; that the best he could hope for was a show trial; and that the local media were failing in their role as watchdogs on power.
But this is not China or Russia. This is the UK, the dissident is Julian Assange and it suddenly seems that the world's leading experts on arbitrary detention have no clue what they are talking about.
