“As one passes through the levels of incarceration—from the minimum to the moderate to the maximum security institutions, and then to the solitary confinement section of these institutions—one does not pass deeper and deeper into a subpopulation of the most ruthlessly calculating criminals. Instead, ironically and tragically, one comes full circle back to those who are emotionally fragile and, often, severely mentally ill.” – Stuart Grassian, “Psychiatric Effects of Solitary Confinement”
