Developments in two major ivory trafficking cases in Tanzania are not what conservationists might have hoped for. The conviction of Boniface Mathew Malyango, known as "Shetani Hana Huruma" ("the Devil has no mercy" in Kiswahili), was hailed by conservation organisations as a victory in 2017, with one of East Africa's most notorious illegal ivory traders. However, his conviction was quietly overturned in mid-2020 - a development that was largely unreported in the press.
