I know many who have spent time in solitary confinement. Some for days, some for months, and some for years. It is a harrowing experience. The people who are held in these conditions are even more at the mercy of their captors. Their time in solitary is usually aggravated by guards who alter the temperature of the cell by making it either too cold or too hot. Guards control the light in the cells and so they mess with the minds of the captives by adjusting the amount of time the lights are on so that the captive looses all sense of day and night and the passage of time. Guards take food from their trays so that the inmates are hungry or they will give them inedible food. Guards will hold mail, keep the captive from bathing regularly and keep them from leaving their cell to exercise. Visiting is limited and only allowed through plexi-glass or via camera. Phone time is limited. Guards have total control and they use it.
Solitary Confinement of youth, the confinement of youth in detention facilities and prisons, and the prosecution of youth as adults is a heinous crime against humanity. The United States is the worst offender of all and by this, condones torture in it's own back yard..
