Before walking out of jail a free man in February, Albert Woodfox spent 43 years almost without pause in an isolation cell, becoming the longest standing solitary confinement prisoner in America. He had no view of the sky from inside his 6 foot by 9 foot concrete box, no human contact, and taking a walk meant pacing from one end of the cell to the other and back again.

Then in April 2016 he found himself on a beach in Galveston, Texas, in the company of a friend. He stood marveling at all the beachgoers under a cloudless sky, and stared out over the Gulf of Mexico as it stretched far out to the horizon. "You could hear the tide and the water coming in," he says. "It was so strange, walking on the beach and all these people and kids running around."

Of all the terrifying details of Woodfox's four decades of solitary incarceration … perhaps the most chilling aspect of all is what he says now. Two months after the state of Louisiana set him free on his 69th birthday, he says he sometimes wishes he was back in that cell.

"Oh yeah! Yeah!" he says passionately when asked whether he sometimes misses his life in lockdown. "You know, human beings … feel more comfortable in areas they are secure. In a cell you have a routine, you pretty much know what is going to happen, when it's going to happen, but in society it's difficult, it's looser. So there are moments when, yeah, I wish I was back in the security of a cell." He pauses, then adds: "I mean, it does that to you."
