The first of the two CMUs was opened quietly, without the public scrutiny required by law, in 2006 in Terre Haute, Indiana; the Marion, Illinois CMU followed in 2008. In fact, at a hearing in my case before I was sentenced, my attorneys argued that giving me the “terrorism enhancement” could result in my designation to a CMU. How right they were! The units are designed to isolate prisoners from the rest of the prisoner population, and more importantly, from the rest of the world. They impose strict limitations on your phone calls home and visits from family and friends — you have far less access to calls and visits than in general population. The communications restrictions at the CMUs are, in some respects, harsher than those at ADX, the notorious federal “Supermax” prison in Colorado. Also, unlike ADX, they are not based on a prisoners’ disciplinary violations. When my wife and loved ones visited me at the CMUs, we were banned from any physical contact whatsoever. All interactions where conducted over a telephone, with Plexiglas and bars between us. Until they were threatened with legal action, CMU prisoners were only allowed one single 15-minute phone call per week.
