Imprisoning our mentally ill?

American jails and prisons have become hospitals for the mentally ill. A murderer doing 20 years at New York’s Sing Sing prison works with schizophrenics serving 24 months for misdemeanors. He tells Warren that sick people should be treated outside. The Sheriff in Chicago says it’s not just inhumane but a waste of taxpayers’ money. How did we get here? What can be done?
