America imprisons a higher proportion of its citizens than anywhere else in the world, and Louisiana more than anywhere else in America. Aleem Maqbool tells the story of one prisoner, Robert Jones, who was jailed in the 1990s for killing a young British tourist in New Orleans. It was a crime another man had already been convicted of, but he was prosecuted anyway. The judge who sentenced the young father to life in prison now says his skin colour sealed his fate.
But even today, more than 23 years after he was arrested, Robert Jones is still not a free man.
