The highly dubious death of Jeffrey Epstein in a US maximum-security prison is another strong reason not to extradite Julian Assange into one – particularly as many of the same people who are relieved by Epstein’s death would like to see Assange dead too.But there is every reason to fear Assange is already in danger, in Belmarsh maximum-security prison, where he is currently incarcerated. As the great journalist John Pilger tweeted six days ago: Do not forget Julian #Assange. Or you will lose him. I saw him in Belmarsh prison and his health has deteriorated. Treated worse than a murderer, he is isolated, medicated and denied the tools to fight the bogus charges of US extradition. I now fear for him. Do not forget him.There is no official explanation as to why Julian’s health has continued to deteriorate so alarmingly in Belmarsh. Nobody genuinely believes him to be a violent danger, so there is absolutely no call for him to be imprisoned in the facility which houses the hardcore terrorist cases.Assange is fighting major legal cases in the UK, Sweden and the United States, yet is permitted visitors for only two hours per fortnight, inclusive of time spent with his three sets of lawyers. All of his visitors have been alarmed by his state of physical health and many have been alarmed by his apparent disorientation and confusion. It is because of Assange’s draconian one year sentence for “bail-jumping” on claiming political asylum that he can be kept in such harsh conditions and with so little access to his lawyers. That is why his sentence was so unprecedentedly stiff for missing police bail. Otherwise, as a remand prisoner awaiting an extradition hearing his conditions would ordinarily be less harsh and his access to lawyers much better. The Establishment has conspired to reduce his ability to defend himself in court. I am not convinced it is not conspiring to destroy him.Craig Murray is an author, broadcaster and human rights activist.
