Tamms is a supermax prison in Illinois where prisoners are held in long-term solitary confinement, often for a decade or longer. In 2010, an Illinois federal court found that "Tamms imposes drastic limitations on human contact, so much so as to inflict lasting psychological and emotional harm on inmates confined there for long periods." A number of states have dramatically reduced their use of solitary confinement, preserving prison and public safety and saving millions of dollars in the process. None of these states have experienced any adverse effect on prison or public safety as a result of reducing their use of solitary confinement. The ACLU calls on the state of Illinois to follow suit and close Tamms.
