DHS Lacked Technology Needed to Successfully Account for Separated Migrant Families [open pdf - 4MB]
From the DHS OIG [Office of Inspector General] Highlights: "In fiscal year 2018, the Department of Homeland Security apprehended more than 100,000 families for illegal entry. From May 5, 2018, to June 20, 2018, DHS adopted a 'Zero Tolerance Policy' to refer for prosecution all adults illegally entering the United States. We conducted this audit to determine the effectiveness of DHS' IT [information technology] systems in tracking detainees and supporting efforts to reunify unaccompanied alien children with separated families."
