These findings are all part of a trove of more than 1,600 pages of previously secret inspection reports written by experts hired by the Department of Homeland Security’s Office for Civil Rights and Civil Liberties. In examining more than two dozen facilities across 16 states from 2017 to 2019, these expert inspectors found “negligent” medical care (including mental health care), “unsafe and filthy” conditions, racist abuse of detainees, inappropriate pepper-spraying of mentally ill detainees and other problems that, in some cases, contributed to detainee deaths.
