Though a scenic, fun and mainly peaceful country, Colombia is still tarnished by its history of violence, particularly between the Cali and Medellin cocaine cartels. Known as 'El Patron', Pablo Escobar was one of the worst instigators of gun crime, assassinations and extreme violence. He was finally imprisoned but escaped in 1992. An elite police squad tracked him down 499 days later; he never saw day 500. Now if the country could only eliminate FARC.
