The Procuraduría de la Nación announced that it would investigate Mossack Fonseca and the Panama papers.[146] On April 12, the newly formed Second Specialized Prosecutor against Organized Crime raided Mossack Fonseca and searched their Bella Vista office as part of the investigation initiated by the Panama Papers. The Attorney General's office issued a press release following the raid, which lasted 27 hours,[147] stating that the purpose was "to obtain documents relevant to the information published in news articles that establishes the possible use of the law firm in illegal activities".[148] The search ended without measures against the law firm, confirmed prosecutor Javier Caraballo of the Second Prosecutor Against Organized Crime.[149]
Spanish authorities had little control over much of the territory of Panama. Large sections managed to resist conquest and missionization until very late in the colonial era. Because of this, indigenous people of the area were often referred to as "indios de guerra" (war Indians) who resisted Spanish attempts to conquer them or missionize them. However, Panama was enormously important to Spain strategically because it was the easiest way to transship silver mined in Peru to Europe. Silver cargoes were landed at Panama and then taken overland to Portobello or Nombre de Dios on the Caribbean side of the isthmus for further shipment.

This is the global professionalization of leaktivism. The days of WikiLeaks amateurism are over."[79]
