An investigation by DW, Netra News, and Süddeutsche Zeitung finds that Bangladesh and Sri Lanka have sent officers implicated in torture and extrajudicial killings on United Nations peacekeeping missions. Reporters Naomi Conrad, Arafatul Islam, and Birgitta Schülke trace individual officers from Bangladesh's Rapid Action Battalion, a police unit accused of running what victims and rights groups call a death squad, into UN vetting records and deployment rosters. Interviews with survivors of torture and family members of people killed describe specific raids and detentions, while documents and cross-referenced personnel files show how accused officers pass through UN screening meant to filter out human rights abusers. The film also examines Sri Lankan cases with similar allegations tied to the country's civil war era security forces. Officials connected to the vetting process are pressed on why the system keeps missing these names, and the reporters lay out what the UN's own rules require versus what its records actually show. The result is a tightly reported piece on how peacekeeping's credibility depends on background checks that, in these cases, appear to fail.
