Lets be honest here, it might not be 60 years, but it is still enough of a beat down to successfully enforce the American anti-wistleblower policy that is emerging. That is 35 years after the past 5 years he has already spent in prison, and completely ignoring the 1 year he spent being tortured in solitary confinement.
Lets face it, he deserves to be free, but the American government is using him as a symbol of what will happen to anyone who dares go against the establishment and who dares report on the evils of the American government.
