Leonor La Rosa and the 2000 Diplomatic Shield for a Torturer
By Desmond Okafor ·
A torture survivor was denied justice when the State Department overrode the FBI to shield a Peruvian intelligence chief who had permanently disabled her.
Leonor La Rosa was broken by the state she served. An agent of the SIE—the Peruvian intelligence service whose counterintelligence wing operated as the primary instrument of internal repression—La Rosa was targeted, tortured, and permanently disabled because her superiors suspected she had leaked information to journalists about the government’s plans to intimidate the press. The man who oversaw her destruction was Tomás Ricardo Anderson Kohatsu, the Chief of Security of the SIE’s Counterintelligence section, a man whose career was defined by the systematic breaking of human bodies.
For years, the Peruvian government sought to keep men like Anderson Kohatsu insulated from the consequences of their cruelty. But in March 2000, the regime made a catastrophic tactical error. They sent Anderson Kohatsu to the United States to testify before the Organization of the American States, the regional diplomatic body where Peru sought to present its official narrative. They believed the prestige of an official mission would act as an invisibility cloak. It did not. This account is reconstructed from the archive's description of a three-page State Department cable, as the original pages are not currently available.
Houston Airport
On March 9, 2000, the invisibility cloak vanished at the Houston airport. The FBI detained Anderson Kohatsu upon his arrival, acting on the requirements of the U.S. Justice Department. The Justice Department’s objective was clear: they wanted to prosecute Anderson Kohatsu under the Torture Victim Protection Act of 1991, a federal law that allows for civil suits and criminal accountability for officials who commit torture regardless of where the act occurred.
For a few brief hours, the statutory mandate of the Justice Department outweighed the diplomatic preferences of the State Department. The detention of a foreign intelligence chief on American soil was a victory for the rule of law and a direct reckoning for the permanent injuries suffered by Leonor La Rosa. However, the machinery of the State Department quickly moved to neutralize the arrest. Invoking diplomatic immunity, the State Department overrode the FBI and the Justice Department, allowing Anderson Kohatsu to return to Peru without facing a judge.

"A First Class Problem"
By March 18, the fallout had reached the desk of Thomas Pickering, the Under Secretary of State for Political Affairs and the highest-ranking career diplomat in the U.S. government. Pickering was not concerned with the moral imperative of prosecuting a torturer; he was concerned with the diplomatic embarrassment of a botched operation. In the record, Pickering expresses anger at the Peruvian government for creating "a first class problem" for the U.S. government by sending a known human rights abuser into a jurisdiction where he could be legally seized.
Pickering’s frustration was directed at Fernando de Trazegnies, the Peruvian Foreign Minister from 1998 to 2000, a legal scholar tasked with managing the international image of a regime under scrutiny. According to the record, Pickering admonished de Trazegnies "never to send GOP representatives like Anderson Kohatsu to the United States under such circumstances." In this context, "GOP" refers to the Gobierno de Perú, the government representatives of the regime.
De Trazegnies responded with a performative denial, claiming he had no knowledge of the case. The pattern suggests this was a diplomatic fiction. The structural improbability of a counterintelligence chief traveling to the U.S. for official testimony before the OAS without the explicit clearance of the Foreign Minister is absolute. De Trazegnies was not ignorant; he was lying to maintain a veneer of plausible deniability while the State Department cleaned up the mess.
The TVPA Mandate
The conflict between the FBI's detention and the State Department's release highlights a jagged rift in American governance. On one side was the Justice Department, operating under the Torture Victim Protection Act to hold abusers accountable. On the other was a State Department practicing a brand of realist geopolitics that viewed the torture of a woman like Leonor La Rosa as a secondary concern to the stability of a bilateral relationship with Peru.
Pickering attempted to bridge this gap with rhetoric. He told de Trazegnies that the case did not seem "closed either morally or legally, and that further GOP steps to ensure justice is served would send a powerful message." But this was a hollow promise. The record shows that the immediate action taken by the State Department was the granting of immunity. The words "morally or legally" were not a commitment to future prosecution; they were a tool of leverage.
If the file is shaped the way it looks, Pickering was using the threat of future legal action to punish Peru for the inconvenience of the Houston airport incident. The "powerful message" was not intended for the victims of the SIE, but for the Peruvian Foreign Ministry, warning them that their incompetence in managing the travel of their torturers had created an unacceptable liability for Washington.
The Peruvian Gamble
The decision to send Anderson Kohatsu to the U.S. was too high-risk to be a simple mistake. The desk's reading is that the Peruvian government used Anderson Kohatsu's travel as a stress test. By sending a known abuser to a public international forum in the heart of a prosecuting jurisdiction, the regime was testing the current threshold of U.S. tolerance for the abuses of the Fujimori era. They wanted to know if the TVPA was a real threat or if the State Department's preference for stability would still override the law.
They got their answer. The FBI made the arrest, but the State Department provided the exit. The Peruvian government learned that as long as they wrapped their abusers in the flag of diplomatic immunity, the U.S. executive branch would prioritize the avoidance of a "first class problem" over the delivery of justice for the disabled and the tortured.
Furthermore, the gap between the FBI's rapid detention and the State Department's rapid override suggests a deeper, unrecorded complication. The desk's reading is that the U.S. intelligence community likely had a prior operational relationship with the SIE's counterintelligence section. A simple diplomatic error does not usually result in such a swift and total erasure of a criminal detention. The speed of the release suggests that Anderson Kohatsu was protected not just by his passport, but by the interests of those in Washington who valued the SIE's intelligence more than the Justice Department valued the law.
What a full release of these files would show is the specific point of contact between the SIE and U.S. intelligence—the shared objectives that made Anderson Kohatsu too valuable to prosecute. The still-withheld pages are protecting the names of the American officials who signaled that the torture of Leonor La Rosa was an acceptable cost of doing business in Lima. In the end, the State Department did not solve a problem; they validated a system of impunity. The cost of that validation was borne entirely by the victims, whose pain was treated as a diplomatic inconvenience.
