Why is investigating corruption vital for global security?

How did an NGO going undercover help to bring down the brutal Khmer Rouge? And how did they go on to uncover corporate complicity in producing blood diamonds? And, more recently, how did they use commercially available data to identify the companies supplying jet fuel to the Russian planes that bombed civilians in Ukraine?

In this episode of Sensing the Signal, we talk to Patrick Alley, a founder of Global Witness, who spent three decades investigating corruption and catching Very Bad People at the nexus of war, environmental crimes, and human rights abuses. We discuss how corruption underpins many of the world's conflicts and security problems.
