This episode contains descriptions of severe injuries. Last week, a devastating fire swept through a derelict building in Johannesburg that housed desperate families who had no place else to go. The authorities had been repeatedly warned that it was a potential firetrap. Nothing was done, and at least 76 people died. Lynsey Chutel, who covers southern Africa for The Times, explains how Johannesburg, once a symbol of the hope of post-apartheid South Africa, became an emblem of just how bad the country’s breakdown has become. Guest: Lynsey Chutel, a southern Africa correspondent for The New York Times.
