In the early 1960s, an 18-year-old African American man named Robert King was sentenced to the Louisiana State Penitentiary at Angola. He would be in and out of that same prison for most of the rest of the decade. In 1969, Robert was sentenced to Angola again, but this time for a crime he claimed he did not commit. Of course, no one believed him. But in 2001 forensic evidence cleared him of the crime and he was set free after spending an appalling 29 years in solitary confinement. 29 years.
