The report summarized the results of the inspections:
"Upon entering some facilities, detainees were housed incorrectly based on their criminal history. Further, in violation of standards, all detainees entering one facility were strip searched. Available language services were not always used to facilitate communication with detainees. Some facility staff reportedly deterred detainees from filing grievances and did not thoroughly document resolution of grievances. Staff did not always treat detainees respectfully and professionally, and some facilities may have misused segregation. Finally, we observed potentially unsafe and unhealthy detention conditions.
Detainees ... reported long waits for provision of medical care, poor conditions in bathrooms and insufficient hygiene supplies. OIG inspectors also observed expired, moldy, and spoiled foods in the kitchen in four facilities."
The report also recommends that ICE improve its oversight of detention facility management and operations. In an official response, ICE concurred with the findings and promised to strengthen oversight and improve overall conditions.
Critics of President Trump's immigration policies say the findings are not new, as they predate the current administration.
A 2015 report by the National Immigrant Justice Center questioned ICE's ability to oversee the detention centers it uses.
In a statement on the 2017 report, the center's executive director, Mary Meg McCarthy, said:
"ICE's inability to provide for the safety and health of the tens of thousands of immigrants in its custody has been documented for years. Today, we are calling on Congress to demand accountability and drastically reduce ICE's detention budget.
"While the Inspector General's report provides documentation of extensive abuses, its remedy is incredibly insufficient: it directs ICE field office directors to review the areas of concern. We know from earlier directives that ICE's internal review processes fail to generate meaningful change."
The Women's Refugee Commission said the report is consistent with what the organization and its partners have "documented for years" from visits to ICE detention facilities, as well as with research it has conducted over 20 years. Katharina Obser, senior program officer at WRC, said in a statement:
"This week's OIG report spells out what WRC and our partners have documented for years, making clear the critical need for greater oversight and reform. Instead, the Trump administration is intent on lowering or eliminating standards for immigration detention – putting detainees' lives at risk – all while promising to ramp up detention on a grand scale. As Congress continues to debate DHS FY 18 appropriations, the OIG's findings show that now is not the time to expand a detention system that ICE is not capable of effectively and safely running. Detention must be reduced and, where needed, humane alternatives to detention, implemented in its place."
