An urgent exposé of the mental health crisis in our courts, jails, and prisonsAmerica has made mental illness a crime. Jails in New York, Los Angeles, and Chicago each house more people with mental illnesses than any hospital. Across America, as many as half of all inmates have a psychiatric problem. One in four fatal police shootings involves a person with such disorders.In this revelatory book, journalist Alisa Roth goes deep inside the criminal justice system to show how and why it has become a warehouse where inmates are denied proper treatment, abused, and punished in ways that make them sicker.Through intimate stories of people in the system and those trying to fix it, Roth reveals the hidden forces behind this crisis and suggests how a fairer and more humane approach might look. Insane is a galvanizing wake-up call for criminal justice reformers and anyone concerned about the plight of our most vulnerable.
