Sensory deprivation, isolation, control units... these terms represent the all-too-real and horrible realities to which thousands upon thousands of u.s. prisoners are subjected, day in and day out. In this short pamphlet, Russell Maroon Shoatz, a veteran of the Black Liberation Army, explains the realities behind these terms, revealing a cruel world of "clean" torture which may not leave physical marks, but is designed to inflict deep psychological wounds. Shoatz writes from experience, having been incarcerated in such inhumane conditions for over twenty years now.
