GAULA is an acronym for Grupos de Acción Unificada por la Libertad Personal or Unified Action Groups for Personal Liberty, specialising in solving hostage-taking. These are elite units established in 1996 exclusively dedicated to the combating of kidnapping and extortion. They are composed of highly qualified personnel who conduct hostage rescues and dismantling of criminal gangs at the root of crimes which compromise the personal freedom of Colombians. Buenaventura is probably the most violent city in Colombia and due to drugs trade and shipment to other parts of the continent gangs of criminals and paramilitaries are present in many neighborhoods of the city and daily violence and killings are daily occurrences.
