51 is to ensure the security of the President of the Republic, of the Vice-President and of their next of kin, the Presidential General Staff has always had an intelligence unit, under various names, which committed many illegal acts that especially violated human rights in Guatemala. The “Archivo” is one of the names given to said intelligence unit, and it is probably the name by which it is known most often, although it was also called Regional Telecommunications Office and Presidential Security Department. The “Archivo” carried out intelligence operations based on the fieldwork of the intelligence units in geographic areas in the interior of the country or in the city; it also gathered information on the activities of any person or institution that had been defined as an “internal enemy.” Once a person or an institution had been selected, they were labeled as objectives for intelligence units. The hierarchical structure of the Presidential General Staff, as regards its officers and those in charge of the various sections, was based on a first and second officers in charge. It has analysis sections that are technical in nature, operational and administrative sections. Therefore, no intelligence agent, whatever his rank, can autonomously plan, prepare and implement a special intelligence operation, as any operation would require a specific plan and a written or verbal order. The murder of Myrna Mack Chang fits into this systematic pattern of an intelligence operation, as she was followed after a file had been received with her profile, and the intelligence unit of the Presidential General Staff used a set of resources. At that time, the director of the National Police had previously been the director of the “Archivo.” This person was at the scene of the crime and he eliminated any possibility of obtaining any type of prints, when usually lower-rank agents, and not the director, analyze any crime scene. The police took no prints arguing that it had rained, but it was proven that at the time of the crime that day it had not rained. They also cleaned whatever residues might be on Myrna's fingernails, demonstrating an attitude that altered the scene of the crime. The data reporting certain entries to and exits from the offices of the Presidential General Staff on the day of the murder were manually altered. The authorities of the Guatemalan Ministry of Defense refused to provide the information to the judges to learn in detail the entries and exits of vehicles, activity reports, among others, an action that breached the Guatemalan legal order that establishes, in the Criminal Procedures Code, a mechanism for the judges to obtain classified information and maintain due confidentiality. Possible classification of a document as secret does not and cannot justify not providing such material to the judges. From the time when she was summoned to render her expert opinion before the Inter-American Court, she has feared for her personal safety. Specifically, her computer was examined on December 22 and 26, outside business hours and during vacations. She also received a number of threatening phone calls in February, 2003. She filed complaints regarding all the above. She is afraid that some entity linked to the Guatemalan State may react violently because she has given her expert opinion. m. 32 Expert opinion of Alicia Neuburger, a psychologist32 An Argentinean national.
