As I tour the country, I get to talk to prison psychiatrists and social workers and various other kinds of experts on the front line, and I have a number of contacts in CSC who tell me—and I have every reason to believe them—that CSC is capable of delivering state-of-the-art mental health and substance abuse treatment. It's simply a matter that they cannot fill the positions.
To your first question, prison is not an ideal place to treat mental illness. Let me put that in as understated a manner as I can. As we grow the rate of incarceration, it is likely to become even less hospitable to mental health treatment.
One of the things we're going to see as the population grows is that correctional officers, who engage with inmates on a regular basis, are going to become more standoffish, more cautious, right? It's that kind of personal contact, that modelling of pro-social behaviour, that does good things for people with mental illness and substance abuse problems. There will be less of that as crowding takes hold.
