There's always a staggering amount of money lost in illegal activities, but is it really so big that it can cause a crisis? I'm neither an economist nor a police investigator, but the accusation "they stole the money and spent it on drugs and whores" sounds more like sensationalism to get a viewer angry then a real reason for the crisis
That wasn't the reason for the crisis. Go watch the movie. It's an interesting piece of work. The journalist is quite knowledgeable and asks all the right questions.
