Dirección de Inteligencia Nacional

Under decree #521, the DINA had the power to detain any individual so long as there was a declared state of emergency. Such an administrative state characterized nearly the entire length of the Pinochet government. Torture and rape of detainees was common:

In some camps, routine sadism was taken to extremes. At Villa Grimaldi, recalcitrant prisoners were dragged to a parking lot; DINA agents then used a car or truck to run over and crush their legs. Prisoners there recalled one young man who was beaten with chains and left to die slowly from internal injuries. Rape was also a recurring form of abuse. DINA officers subjected female prisoners to grotesque forms of sexual torture that included insertion of rodents and, as tactfully described in the Commission report, "unnatural acts involving dogs."[3]

As of September 11, 1973, the military dictatorship worked with DINA to censor channels, newspapers, and radio transmissions that supported the Popular Socialist Union and supporters. A decree by the Junta established that all public information would have to be inspected and revised by the Junta before airing, and a couple days later an "Office of Censorship" was created to supervise all media. A lot of newspapers received their work back scribbled out with red ink.

Through coercion, murder, and kidnappings, television outlets masked the truth on the coup d'état as a plan by the military of Chile. Various international cable news networks were banned by DINA to prevent the news of the forced coup d'état by the military. Some international networks were convinced to lie by the Junta about social and political aspects of Chile.

The censorship breached particular homes and public services, and on September 23, 1973, DINA sent policemen to register households and institutions. They searched subversive evidence such as books by Pablo Neruda, articles on social sciences, political science, human rights, and those who were rounded up and burned at the Plaza de Armas (Santiago).

The United States backed and supported the Fatherland and Liberty Nationalist Front, which funded and directed the first coup attempt against Allende's regime, known as the Tanquetazo. The CIA established links with DINA after the successful 1973 Chilean coup d'état. Ties were cut, however, after the assassination of Orlando Letelier in Washington DC, which DINA agent Michael Townley was directly tied with and which eventually led to the disbanding of the DINA in 1977.

The DINA was involved in Operation Condor, as well as Operation Colombo. In July 1976, two magazines in Argentina and Brazil appeared and published the names of 119 Chilean leftist opponents, claiming they had been killed in internal disputes unrelated to the Pinochet regime. Both magazines disappeared after this one and only issue. Judge Juan Guzmán Tapia eventually asked Chilean justices to lift Pinochet's immunity in this case, called "Operation Colombo", having accumulated evidence that Pinochet had ordered the DINA to plant this disinformation, in order to cover up the "disappearance" and murder by the Chilean secret police of those 119 persons. In September 2005, Chile's Supreme Court ordered the lifting of Pinochet's general immunity from prosecutions, with respect to this case.

Certain writers and journalists who opposed the right-wing regime conducted clandestine interviews with individuals enduring life under DINA. Among them was Patricia Politzer, who documented the harrowing experiences of those who suffered in Chile.

One of the testimonies features a mother whose leftist sympathizer son fell victim to forced disappearances in Chile. Despite the removal of Pinochet from power, she never received any information about her son's fate. Numerous others who disappeared or were killed during that period remained unidentified, leaving thousands of families of leftist sympathizers still searching for their loved ones in Chile to this day.

Compensation for these losses was minimal, and children endured immense hardship. In another interview, Politzer recounted the story of a woman who survived being shot alongside other leftists. She emphasized that had she perished at the hands of DINA, her children would have been left without care. These accounts highlight the callous disregard exhibited by DINA and other agencies operating under Pinochet's authority, resulting in children being orphaned. Patricia Politzer's work in "Fear in Chile" vividly portrays the stark realities of life in Chile during the Pinochet era.[6]

DINA was replaced by the CNI (Central Nacional de Informaciones) in 1977 and Contreras was replaced by general Odlanier Mena. By that time, DINA had reached its military goals: assassinate the Movimiento de Izquierda Revolucionaria (MIR) leadership and the main leaders of the Popular Unity, the coalition of the parties that had won the 1970 elections. The dissolution of the CNI occurred in 1990 during the Chilean transition to democracy.

After the fall of Pinochet's regime, Contreras was prosecuted in Chile due to crimes against humanity while heading the DINA and sentenced to 12 years in prison for covert kidnappings, a crime that had not been amnestied. However, judge Víctor Montiglio who had replaced judge Juan Guzmán Tapia gave amnesty to Contreras in 2005.

Finally, on June 30, 2008, Contreras was sentenced to two life-sentences, one for the murder of Carlos Prats and one for the murder of his wife, Sofía Cuthbert. He also received an additional 20-year sentence for illicit association.

In an undated letter to Augusto Pinochet, Michael Townley advised him that Virgilio Paz Romero, an anti-Castro Cuban, was taking photographs of British prisons in Northern Ireland in 1975 as a DINA assignment.[7] The photographs were to be used by the Chilean government at the United Nations in New York to discredit the United Kingdom and accuse it of human rights violations. However, they arrived too late to be used, and were finally published in El Mercurio.[8]

Beginning in late 2014, in response to a request by then Senate Armed Services Committee Chair Carl Levin, the William J. Perry Center for Hemispheric Defense Studies, a U.S. Department of Defense institution for defense and security studies in the Western Hemisphere, has been under investigation by the Department of Defense Office of Inspector General. Insider national security whistleblower complaints allege that the Center knowingly protected a WJPC professor who belonged to the DINA during the dictatorship of Captain General Pinochet, as well as the clandestine participation of Center officials in the 2009 Honduran coup, gross mismanagement, corruption, homophobia, racism, and sexism. "Reports that NDU hired foreign military officers with histories of involvement in human rights abuses, including torture and extra-judicial killings of civilians, are stunning, and they are repulsive," said Sen. Patrick Leahy, D-Vermont, the author of the "Leahy Law" prohibiting U.S. assistance to military units and members of foreign security forces that violate human rights.[9][10][11]
