Ghana used to a model democracy in West Africa, with a free press as one of its cornerstones. The country has many natural resources, it's rich in minerals, cocoa and oil. But there are huge income disparities among its more than 33 million people, and many Ghanaians face poverty. At the same time, corruption has be mounting. And journalists exposing this kind of crime are now facing increasing pressure -- or they get police protection because of death threats against them, some have even been forced to flee the country. Our reporter, Patrick Batarilo, met three investigative journalists from Ghana - and he was impressed by their courage and idealism. All of them have been risking a lot to expose corruption, human trafficking, discrimination and other crimes. And as one of them told our reporter -- just like in the case of the proverbial cat -- too much curiosity can prove deadly. But that's not stopping them.
