Sending criminals and political troublemakers to remote islands has been a pretty normal thing throughout history - just ask Australia or Napoleon. In Central America, the former penal colony on Coiba Island was once home to some of Panama's worst criminals and most threatening political enemies. The prisons on Coiba Island housed over 3,000 prisoners between 1919 and 2003, even after the island became part of Coiba National Park in 1991.
