Mexican authorities on Oct. 1 claimed another coup against the cartels, announcing the arrest of Héctor Beltran Leyva, last remaining kingpin of the Beltran Leyva Organization—the declining crime machine that once controlled much of the west and central parts of the country. Beltran Leyva was taken into custody by army troops "without a shot fired" as he dined in a seafood restaurant in the tourist town of San Miguel de Allende, Guanajuato state. (LAT, Oct. 1) The capture follows that earlier this year of the Sinaloa Cartel's long-fugitive jefe máximo Joaquin Guzmán Loera AKA "El Chapo"—marking another score for President Enrique Peña Nieto, and his supposed new and more sophisticated policy against the cartels.

Tens of thousands of people demonstrated in Mexico and internationally on Oct. 8 to protest the killing of six people and the wounding of at least 20 more the night of Sept. 26-27 by municipal police and people in civilian dress in the city of Iguala in the southwestern state of Guerrero. The demonstrators demanded the return of 43 students who have been missing since that night; all are from the militant Raúl Isidro Burgos Rural Teachers’ College in the town of Ayotzinapa. "They were taken alive, we want them back alive" and "We are all Ayotzinapa" were among the slogans protesters chanted in at least 25 Mexican states and 60 cities, including many in other countries, along with calls for the Guerrero state government and Mexico’s federal government to "go away.”

Gregorio Santos, the populist president of Peru's Cajamarca region, was comfortably re-elected Oct. 5—despite being imprisoned as corruption charges are pending against him. The biggest issue in the race by far was the unpopular Conga gold mine project, majority-owned by US-based Newmont Mining. Peru's central government said it would recognize the victory, while his supporters marched in Lima to demand his freedom. Environment Minister Manuel Pulgar-Vidal called for a "political dialogue with all the actors" to resolve the crisis in Cajamarca. But Jorge Vergara Quiroz, president of the Cajamarca Chamber of Commerce, said that Santos' re-election created a climate of "uncertainty" that would discourage investment, and called on him not to take office. Segundo Mendoza, spokesman for Santos' Social Affirmation Movement (MAS), responded that the party respects private investment. He called on authorities to free Santos, saying he posed no flight risk.

On Oct. 4 authorities in the southwestern state of Guerrero announced that they had found charred human remains in a group of mass graves in Iguala de La Independencia municipality, at Pueblo Viejo community in the countryside northwest of the city. Guerrero chief prosecutor Iñaky Blanco Cabrera would only say that there were human bones and that specialists would need to use DNA tests to identify the victims. State police agents at the site on Oct. 4 told reporters off the record that there could be anywhere from four to 19 bodies, but on Oct. 5 Blanco Cabrera said the total number was 28. It seemed likely that the remains were of teachers' college students missing since the night of Sept. 26-27, when Iguala police opened fire on three buses carrying students from the militant Raúl Isidro Burgos Rural Teachers' College, located in the town of Ayotzinapa. Originally 25 students were reported missing after the incident, but parents and student leaders later raised the number to 43.

Michoacán state police on Sept. 12 found the body of a brother of Servando Gómez Martínez AKA "La Tuta"—leader of the notorious Knights Templar cartel and Mexico's most wanted drug lord. Aquiles Gómez Martínez was found dead of a gunshot wound at his home in the Pacific port city of Lázaro Cárdenas. A 9 mm pistol, two ammunition clips and a box containing 50 bullets were also found at the residence. Prosecutors had identified him and two other purported brothers of "La Tuta," Flavio and Luis Felipe Gómez Martínez, as chief operatives of Los Caballeros Templarios. (EFE, Sept. 19)

Well, this is really cute. With refreshing honesty, Fortune magazine on Sept. 14 issued a list of the "Fortune 5"—the biggest organized crime groups in the world, ranked by their annual revenue estimates. No sources are given, but the Fortune editors presumably relied on international law enforcement intelligence. The results are slightly surprising for those of us who grew up in the era of the Sicilian Mafia and Medellín Cartel. Brave new crime machines have long since eclipsed these entities from the global stage, and far outstripped their earnings from human trafficking, extortion, credit card fraud, prostitution and (above all) drug smuggling. In the number one slot, by a mile, is Yamaguchi Gumi, a wing of Japan's Yakuza, with revenue estimated at $80 billion. A distant second is Russian mafia group Solntsevskaya Bratva, with revenue at $8.5 billion. Three and four are two Italian outfits that have long superceded Sicily's Cosa Nostra: the Camorra, based in Naples, with revenues of $4.9 billion; and the 'Ndrangheta, based in Calabria, with revenues of $4.5 billion. Number five is Mexico's Sinaloa Cartel, with revenues of $3 billion.

On Sept. 18 the US Central Intelligence Agency (CIA) released a number of classified articles from its in-house journal, Studies in Intelligence, including an article about "Dark Alliance," a 1996 series in the San Jose Mercury News that linked the CIA-backed Nicaraguan contra rebels to the sale of crack in South Central Los Angeles in the 1980s. Other US media, notably the New York Times, the Washington Post and the Los Angeles Times, harshly criticized the series' author, investigative reporter Gary Webb, noting, and often exaggerating, flaws in his reporting. Webb lost his job at the Mercury News and was never employed by a major newspaper again; he was found dead on Dec. 10, 2004 in an apparent suicide.

Here we go again. Francis X. Taylor, under-secretary for intelligence and analysis at the Department of Homeland Security, testified before the Senate Committee on Homeland Security on Sept. 10 that operatives of the extremist jihadi movement variously known as ISIS, ISIL or the Islamic State have discussed infiltrating the United States through the Mexican border. "There have been Twitter and social-media exchanges among ISIL adherents across the globe speaking about that as a possibility," Taylor said in response to a question from Sen. John McCain, who wanted to know if any ISIS chatter had been intercepted that "would urge infiltration into the United States across our Southwestern border." But Taylor said he was "satisfied that we have the intelligence and the capability at our border that would prevent that activity." And when pressed further, he admitted: "At present, DHS is unaware of any specific, credible threat to the US homeland from ISIL."
