Criminalizing those with mental illness is a controversial topic with a long and complex history in the United States. The problem has traditionally been dichotomized between criminals (i.e., “bad”) in need of placement in jails and prisons and the mentally ill (i.e., “mad”) who are need of treatment in psychiatric facilities. Recent trends demonstrate significant increases in the rates of mental illness in jails and prisons, as well as increased rates of violence within psychiatric hospitals. This would suggest that there are a group of justice involved individuals who are “indistinguishable” within the traditional dichotomous categories of dangerousness and mental illness. The authors argue for a more nuanced model that dimensionally conceptualizes dangerousness and mental illness; increased attention to situational factors that create facilities appropriate for those who are dangerous and mentally ill and more diversion programs for those inappropriate for incarceration or hospitalization.
