The Dirección Federal de Seguridad (Federal Security Directorate, DFS) was a Mexican intelligence agency. Created in 1947 under Miguel Alemán Valdés with "the duty of preserving the internal stability of Mexico against all forms subversion and terrorist threats",[1] it was merged into the Centro de Investigación y Seguridad Nacional (CISEN) in 1985.
According to Peter Dale Scott, the DFS was in part a CIA creation, and "the CIA's closest government allies were for years in the DFS". DFS badges, "handed out to top-level Mexican drug-traffickers, have been labelled by DEA agents a virtual 'license to traffic.'"[2] Scott says that "The Guadalajara Cartel, Mexico's most powerful drug-trafficking network in the early 1980s, prospered largely because it enjoyed the protection of the DFS, under its chief Miguel Nassar (or Nazar) Haro, a CIA asset."[2]
