The American criminal justice system holds almost 2.3 million people, an alarming and ever-growing number of whom are aged men and women who cannot readily climb stairs, haul themselves up to their top bunk, or walk long distances to meals or the pill line. Their old bones suffer from thin mattresses and winter’s cold, and many of them need wheelchairs, walkers, canes, portable oxygen, and hearing aids. They cannot get dressed, go to the bathroom, or bathe without help. And they are incontinent and forgetful, suffering from chronic illnesses. Many are extremely ill and dying.
