As the matriarch of a family-based drug operation, she built and sustained a heroin and cocaine distribution network centered in Son Banya, a Romani neighborhood in Majorca, for years before her arrest. The clan structure she led made the organization both resilient and deeply embedded in the community. Operation Kabul, which resulted in her arrest alongside nineteen others in 2008, reflected the scale of coordinated effort required to dismantle it.

The murders Soltys carried out in August 2001 targeted members of his own family across the Sacramento area, making his case notable for both its intimate brutality and the extended manhunt that followed. He fled the United States after the killings, triggering federal charges for unlawful flight before ultimately being apprehended. "Nikolay Alekseyevich Soltys (May 19, 1974 – February 13, 2002) was a Ukrainian fugitive charged by the United States District Court for the Eastern District of California in a Federal Bureau of Investigation arrest warrant. The federal charges were for unlawful flight to avoid prosecution and there were California arrest warrants for six murders of his family members in and around the Sacramento area in August 2001."

The assassination of Mahatma Gandhi on January 30, 1948, stands as one of the most consequential political killings of the twentieth century, and Godse carried it out at close range during a prayer meeting — an act of violence against a figure internationally synonymous with nonviolence. His motivation was rooted in Hindutva ideology, and he framed the killing as a political act against what he saw as Gandhi's accommodation of Muslim interests during Partition. The act did not go unwitnessed or unchallenged: an American diplomat in the crowd physically restrained him before police arrived.

As chief of DOPS during Brazil's military dictatorship, Fleury became one of the most feared figures in the country's apparatus of political repression — overseeing interrogations, disappearances, and extrajudicial killings targeting dissidents and leftists. His effectiveness lay in operating at the intersection of state authority and sanctioned lawlessness, where institutional cover made accountability nearly impossible. The scale of harm attributed to him and the unit he led left a long shadow over Brazil's reckoning with that era.

Fish operated for years without detection, preying on children across multiple states during the 1920s and early 1930s — a period when law enforcement had few tools to track crimes across jurisdictions. What made his case particularly unsettling to investigators and the public alike was the combination of prolonged activity, the vulnerability of his victims, and the nature of the offenses, which extended beyond killing. He was ultimately caught not through investigative breakthrough but through his own correspondence — a letter he sent to a victim's family years after the crime.

As leader of the Khmer Rouge, he oversaw a radical agrarian revolution that emptied Cambodia's cities by force, abolished currency and formal education, and subjected the population to mass executions, forced labor, and famine. In under four years, an estimated 1.5 to 2 million people — a quarter of Cambodia's population — perished under his government's policies. What distinguishes his rule historically is the ideological totality of the project: the systematic dismantling of an entire society in pursuit of a agrarian utopia designated "Year Zero."
