"Documents from Guantanamo describe prisoners shackled in excruciating 'stress positions,' held in freezing-cold cells, "

"Lawyers who visited detainees in January 2007 reported that they consistently complained of being too cold in the steel cells, with the air-conditioning turned up too high."

And:
"Conditions in Camp 6
Built to accommodate around 178 detainees, the compound known as Camp 6 is surrounded by high concrete walls with no windows visible on the façade. Inside, detainees are confined for a minimum of 22 hours a day in individual steel cells with no windows to the outside. The only view from each cell is through strips of glass only a few inches wide in and adjacent to the cell door which looks onto an interior corridor patrolled by military police. There are no opening windows and detainees are completely cut-off from human contact while inside their cells."

Such harsh conditions- makes me want to cry for the poor, poor, terrorists.

And:
"Moreover, in December 2006, a new facility opened on the base. This facility, known as Camp 6, has created even harsher and apparently more permanent conditions of extreme isolation and sensory deprivation in which detainees are confined to almost completely sealed, individual cells, with minimal contact with any other human being.

The US authorities have described Camp 6 as a “"state of the art modern facility”" which is safer for guards and “"more comfortable”" for the detainees. However, Amnesty International believes that conditions in Camp 6, as shown in photographs or described by detainees and their attorneys, contravene international standards for humane treatment. In certain respects, they appear more severe than the most restrictive levels of “"super-maximum”" custody on the US mainland, where conditions in some units have been criticized by international bodies and US courts as incompatible with human rights and US correctional standards."

"CONFINEMENT IN SUPERMAXIMUM PRISONS
Prisoners like Todd are held in fortresslike facilities under a regime of complete isolation. Confined in single, sometimes windowless, cells for 23 or more hours a day, they are completely dependent on the prison staff who walk the tiers, pushing meals, mail, and toilet paper through ports in the heavy doors of the cells. Inmates are taken out—cuffed, often shackled, and under guard—only for showers or brief exercise in solitary yards. This extreme form of confinement goes beyond the “segregation” that has always been a necessary aspect of imprisonment. Prison officials and the media often refer to prisoners in supermaximum facilities as the “worst of the worst,” but although some of these inmates have committed serious crimes, it is primarily behavior in prison rather than criminal history that determines placement. In addition, not all supermaximum prisoners are being punished for serious misbehavior within the prison. Some may be under protective custody or in preventive detention, while others may have committed a number of relatively minor infractions against prison rules.

Exact figures on supermaximum confinement are not available, but we know that the United States has more than 60 such facilities housing a total of well over 20 000 people.2 These facilities, which had been constructed during the expansion of the US prison complex that began in the early 1980s, share the punitive and individualistic philosophy that accompanied that expansion. Behavior in prison, like crime itself, has increasingly come to be understood primarily as a matter of individual choice divorced from its social context. Thus, for example, a supermaximum prisoner deprived of all but the most minimal options is offered the “choice” of returning a meal tray or keeping it in his cell as a gesture of defiance. Defiant behavior is then cited as proof that this form of confinement is necessary."

Imagine the idea that some would think that crime is thought to be an individual choice, rather than due to the social context.
It should noted that supermaximum is used in some instances as way of protecting prisoners from other inmates, and that prisoner may prefer this to being in a open prison population. I wonder how long a terrorist would survive in an open prisoner population in the US.
