Over the past four years roughly a million immigrants have been incarcerated in dangerous detention facilities in our taxpayer-financed private prison system. A growing number of news reports and investigations confirm that for many of the people funneled into this system, it is a living nightmare. Children were abused, women were raped, and men died from lack of basic medical attention.
These facilities are run by two Wall Street-backed companies that actively promote the criminalization and incarceration of immigrants in the United States -the Corrections Corporation of America (CCA) and the GEO Group.
