Rusty Young has spent his life living, and writing about things that most of us would feel uncomfortable thinking about, let alone actually experiencing. Strangely enough, he and I first met at law school many years ago. But while after graduation, I left to join the digital industry, he travelled to South America where he met Thomas McFadden, a convicted English drug trafficker who ran tours inside Bolivia's famous San Pedro Prison, and ended writing about his story in his first bestselling book, ‘Marching Powder’. Rusty was then recruited as a Program Director of the US government's Anti-Kidnapping Program in Colombia, after which he released a new novel about Colombia's child soldiers called 'Colombiano’, and a documentary on the drug trade called ‘Wildlands’. Catching up with him in Sydney, we spoke about the global drug trade, how Cartels design their technology stack, and the economics of the world’s strangest prison.
