Assignment: Italy's mafia whistleblower

Last year in Italy the biggest anti-mafia trial in 30 years reached a climax. On the stand were the Calabrian ‘Ndrangheta: they are estimated to run 80 percent of Europe’s cocaine and to make more money in a year than McDonalds and Deutsche Bank put together. With access to mafioso-turned-collaborator Emanuele Mancuso, journalist Francisco Garcia looks at why Emanuele testified against his powerful family. What has this trial meant for the 'Ndrangheta? And has it changed life for Calabrians today?
