People who commit high-profile acts of gun violence are often mentally ill, like Adam Lanza, James Holmes and Jared Loughner. Conversations about gun control often come with calls for improved mental health care, but while people understand the mental health care system needs to be improved, that doesn’t mean they can tell when someone actually needs help.

Last month, the city of Glendale opened a new court specially designed for the mentally ill. Advocates say it’s a critical issue; according to an analysis of government data by the Treatment Advocacy Center, mentally ill people in Arizona are nearly ten times more likely to be in the criminal justice system than in hospitals.
