Given that a documentary from around 2016 exposed human rights abuses and the improper management of a G4S-run youth detention facility in the United Kingdom (UK), whereupon the UK government terminated G4S’s contract with a different G4Srun facility after it was revealed that prisoners had taken control of the facility, and in view of a protest by local prisoners citing the same in South Africa a few years later, what (a) are the reasons that his department did not review its contract with G4S then, as its UK counterparts and (b) consequences did G4S management and officials face for the allegations made by South African prisoners in its facilities?
