The Panama Papers opened yet another window on the global system of financial corruption, showing how political leaders and businesses use shell companies in secrecy havens like the British Virgin Islands and many US states to evade taxes and hide corruption and other crimes. Yet the system of corruption depends on another factor beyond secrecy, one that is perhaps even more important: impunity. Impunity means that the rich and powerful escape from punishment even when their malfeasance is in full view.
