english: When I lived in Colombia in the late 1990s, Medellín was the murder capital  of the world, but it changed course, and it did this by deliberately investing in its low-income and most violent areas and integrating them with the middle-class ones through a network of cable cars, of public transport, and first-class infrastructure, and in the process, it dropped homicide by 79 percent in just under two decades.
non_english: Kada sam živeo u Kolumbiji kasnih '90-ih, Medijen je bio prestonica ubistva u svetu, ali je promenio svoj pravac tako što je svesno uložio u siromašna, najnasilnija područja i uključio ih u područja srednje klase kroz mrežu tramvaja, javnog prevoza i prvoklasne infrastrukture. U procesu je smanjio broj ubistava za 79% u samo dve decenije.
