In some countries, they call them the "abandonados," the abandoned ones. They're the impoverished mentally ill and mentally disabled patients being warehoused in psychiatric asylums that are more run-down, more uncaring than the most brutal American prisons. Confined in cage-like cells, tied to beds soiled with human waste, medicated to the point of senselessness, or wandering naked in unheated and garage-like wards, they live in what can only be called the shadows, their plight unseen and too easily ignored by the rest of the human family. Working first as a journalist, later as a volunteer for the human rights organization Mental Disability Rights International, photographer Eugene Richards gained access to psychiatric institutions in Mexico, Argentina, Armenia, Hungary, Paraguay, and Kosovo. His wrenchingly intimate images reveal the often inhumane treatment suffered by the mentally disabled. Offered little that would qualify as effective care, patients are denied even the most basic human amenities: privacy, protection from harm, clean clothing. Accompanying the book, A Procession of Them, is a DVD of a short film of the same name. Directed and narrated by Richards, this unique and expressionistic film speaks of the chaos, claustrophobia, and loneliness of these living hells. Making us face some hard truths, A Procession of Them drives home the point that when it comes to the plight of the mentally disabled, "no one much cares." As Richards concludes, it's "as if there is a kind of worldwide agreement that once people are classified as mentally ill or mentally retarded, you're free to do to them what you want."
