The Justice Department has blasted Alabama’s prison system as “broken,” saying prisoners are being held in unsafe, filthy and overcrowded conditions, while suffering from routine violence and rampant sexual assault. In a sweeping new report, Justice Department investigators found prison guards are woefully undertrained and understaffed, leading to frequent rapes, beatings and homicides that sometimes go unreported. The report comes just weeks after eight inmates at Alabama’s Holman prison ended a hunger strike against their solitary confinement after prison officials shut off water to their cells.
