Book excerpt: The Cali drug cartel changed the face of organised crime. For over twenty years it pumped thousands of tons of cocaine across the world, laundered billions of pounds in illegal profits and was responsible for untold murders and assassinations. Based in the city of Cali, the three founders brought an unprecedented degree of organisation and planning to the drugs trade and through violence, terrorism, intimidation and bribery they became a major threat to society. For the first time the gang's founders are scrutinised and the efforts that brought them to justice are recreated.
