Watch the ZO, from The Marshall Project :: "Life Inside" series

​“The Zo,” prison jargon for The Twilight Zone, was based on a huge archive of letters compiled by the American Prison Writing Archive, a remarkable open-source database invented by Doran Larson, a professor of creative writing at Hamilton College. It is a disturbing study of a struggle between prisoners and their captors, waged not with fists or weapons but with deliberately disorienting rules and impossible tasks. Guards mess with the prisoner’s heads. Those incarcerated try to keep their grip on reality by clinging to details—days until parole, prices of items in the commissary, the minutiae of routine. Guards escalate, inflicting arbitrary transfers or random stints in isolation.
