Frontline: The Released
Of the 700,000 people released from prison this year, more than half will be mentally ill. They will try to re-enter society unsupervised, with nothing but a bus ticket, $75, and two weeks’ worth of medication in their pockets. Two-thirds of mentally ill offenders are re­arrested within 18 months of their release. In a troubling sequel to its 2005 documentary The New Asylums, Frontline returns to Ohio to ­follow two all-too-typical cases. Tuesday, April 28, at 9 p.m., PBS; check local listings
