I have no doubt Assange was mistreated.
However being silent is not the same as condoning and I am unsure about what powers the judge wields here.
I would also not even dare suggest a judge may be biased until I have read a verdict. Note how the International Bar Association's Press Release, being carefully worded, doesn't say so either. Though probably they would never except maybe once in a hundred years, them being lawyers.
The main thing I am unsure about, and where I don't share Murray's conviction, is the strength of the prosecutions legal argument.
