Mexico Opens DFS Secret Police Files at AGN

Under President Vicente Fox's government, the Archivo General de la Nación (AGN) begins releasing files from the Dirección Federal de Seguridad (DFS — the Mexican secret police). The files reveal systematic surveillance of students and political activists in 1968, intelligence sharing with the CIA, and internal documents confirming the scale of the operation at Tlatelolco. The Galería 1 collection at AGN becomes a critical resource for researchers.
