Miscarriages of justice are sometimes accidents. But in some cases they are the result of deliberate framing by rogue officials. And in some cases they are the result of deliberate framing by many officials.
Mark Barnsley, an anarchist activist from Sheffield, was beaten up by a 15-strong drunken gang in 1994. He was subsequently charged with Grievous Bodily Harm against the gang, the crimes he was a victim of. Despite his appalling injuries, none of his attackers was ever charged.
Conviction of such crimes would get most people a lot of Community Service or a hefty fine, perhaps a short term in prison at most. Mark, a man with no history of violence, got twelve years.
The prison system has given him as hard a time as the rules will allow, and often broken the rules and to make it harder still.
Despite being eligible for parole, he refused to apply because in doing so he would have to concede remorse for his offence; to admit guilt for a crime he did not commit.
