Three hundred and fifty thousand: That's a conservative estimate for the number of offenders with mental illness confined in America's prisons and jails.
More Americans receive mental health treatment in prisons and jails than in hospitals or treatment centers. In fact, the three largest inpatient psychiatric facilities in the country are jails: Los Angeles County Jail, Rikers Island Jail in New York City and Cook County Jail in Illinois.
In the 19th century, the mentally ill were often sent to horrific asylums. Today they fill the nation's jails; the conditions aren't much better. Last year, almost 1.1 million people with serious mental illnesses were arrested nearly 2 million times.
It's those old asylums — mostly closed, often abandoned — that have fascinated photographer Christopher Payne. A few years ago, he put together a book of images from those buildings, titled Asylum: Inside The Closed World Of State Mental Hospitals.
