The Department of Justice report out earlier this year showed that officers in the Chicago Police Department commit suicide at a higher rate than officers in other big city departments. It also showed that there are just three mental health counselors for 12,000 officers. This week aldermen in the City Council introduced an ordinance to increase the number of counselors at CPD, but they did not say how the measure would be funded.

To better understand the mental health challenges that officers face, Morning Shift talks to John Violanti, research professor in the Department of Epidemiology and Environmental Health at the University of Buffalo where he studies psychological and biological indicators of chronic police stress and the epidemiology of police suicide and PTSD.
