Political Arrests and Torture in São Paulo (1973)

This confidential U.S. State Department report documents systematic political repression in São Paulo in 1973, drawing on multiple sources, including a professional interrogator working for a military intelligence center in Osasco. The report indicates that political arrests for alleged violations of the National Security Law were constant throughout the year, targeting both suspected militants and individuals identified as political opponents or “idealists” of the regime.

It provides detailed and graphic accounts of interrogation practices, noting that torture was routinely employed as a standard method of extracting information. Techniques included electric shocks, starvation, and the “parrot’s perch,” a form of suspension torture. Testimonies suggest that dozens of prisoners were held at facilities such as the OBAN interrogation center, where all detainees were subjected to some form of abuse, regardless of the severity of their alleged offences. The report also documents extrajudicial killings, described by sources as common practice, including execution methods designed to ensure victims could not be identified.

Beyond documenting repression, the report highlights growing concern within Brazilian society. Cases such as the death of student Alexandre Vannuchi Leme galvanized opposition among students, clergy, and segments of the political and media elite, including figures like Cardinal Paulo Evaristo Arns. Increased repression, including university raids and censorship of major publishing houses, contributed to heightened social tensions and fears of political instability, even as the regime maintained overall control.

Declassified in 2005, the document later contributed to investigations by Brazil’s National Truth Commission, helping uncover further evidence of “psychophysical abuses.” Overall, the report demonstrates how torture, surveillance, and extrajudicial violence were embedded within bureaucratic and institutional structures, enabling widespread repression with limited accountability
