Rebroadcast: What's wrong with the global supply chain?

On this edition of KCBS In Depth that first broadcast earlier this year we take a grand tour of the global supply chain with Wall Street Journal technology columnist Christopher Mims. In his new book, "Arriving Today," he explains what keeps this finely tuned global system of container trucks, ships and warehouses running, and why so often over the past two years it's fallen short.
