(NEWSER) – Rick Raemisch is no average prisons chief, but these aren't average times for US prisons. Newly appointed as Colorado's chief of corrections, Raemisch put himself in solitary confinement for 20 hours to experience the most controversial form of punishment in prisons today, the New York Times reports. "I thought he was crazy," said the prison warden. "But I also admired him for wanting to have the experience." Raemisch wrote about the scary isolation, fitful sleeping, and blaring noise from other cells in a Times op-ed last month. Now he aims to further reduce the use of solitary confinement in Colorado's 20 state-run prisons.
