Two unidentified men on a motorcycle gunned down Colombian labor leader Milton Enrique Rivas Parra on Dec. 11 in Puerto Gaitán, a city in the central department of Meta. He was hit by 17 bullets, according to his family. Rivas was a leader in the Meta section of the Workers' Labor Union of the Petroleum Industry (USO) and in a local grassroots organization, the Villa Ortiz Community Action Council. He had been receiving death threats, which he first reported to Colombian prosecutors on Aug. 25.

On Dec. 5 Argentine judge Alicia Vence opened an investigation into the possible involvement of four former executives of Ford Motor Company's Argentine subsidiary in the kidnapping and torture of at least 25 autoworkers during the "dirty war" against suspected leftists under the 1976-83 military dictatorship. According to prosecutor Félix Crous, former Ford Motor Argentina president Nicolás Courard, former manufacturing director Pedro Müller, former industrial relations director Guillermo Galarraga and former security chief Héctor Sibilla are suspected of collaborating with the military in the abuses, which took place in 1976 next to the company's plant in the city of General Pacheco in Buenos Aires province, just north of the city of Buenos Aires.

The London-based corporation HSBC, Europe's largest bank, will pay the US government $1.92 billion in fines for its failure to prevent money laundering through some of its affiliates, including its Mexican branch, US assistant attorney general Lanny Breuer announced at a press conference in Brooklyn on Dec. 11. However, the US Justice Department has decided not to bring criminal charges against the bank. Breuer noted that bank executives faced some penalties. "HSBC has replaced virtually all of its senior management," he said, "and agreed to partially defer bonus compensation for its most senior officials" over a five-year period.

It never fails. Every time something ghastly happens, from the Wisconsin Sikh temple massacre to the Oslo terror attacks to the Fort Hood Shootings to (d'oh!) 9-11, lugubrious conspiranoids have got to descend like ravenous vultures with bogus theories about how it was a "false flag" job perpetrated by a "Manchurian Candidate." The horrific bloodletting at the elementary school in Newtown, Conn., is, alas, no exception. And in this case, the theory has simply no basis in reality—it isn't even a distortion, contortion, embellishment or obfuscation—it is a simple invention, straight up. Yet animated partisans are plastering posts about it on my Facebook wall right and left—seemingly in all earnestness. Big ups to Talking Points Memo for rising to the tiresome ocassion of shooting down this jive:

The Libyan government closed the country's southern border with Algeria, Niger, Chad and Sudan on Sunday and declared southern Libya as a military zone. The move was in response to  growing lawlessness  in Libya's southern provinces of Ghadames, Ghat, Obari, al-Shati, Sebha, Murzuq and Kufra. Representatives of the southern provinces had been boycotting legislative sessions due to the government's failure to assist in curbing the violence in the region. Government officials indicated that the closure would only last until order has restored. There was indication that some of the problems in the southern provinces were due to deteriorating conditions in Mali and the expected international military response.

New Age tourists will be flocking to Mexico's Yucatan Penninsula this week for the "end of the Maya calendar" (sic). But Yucatecan Maya elder José Manrique Esquivel protests that he and his followers will be barred from performing ceremonies at the peninsula's ancient Maya sites. "We would like to do these ceremonies in the archaeological sites, but unfortunately they won't let us enter," Esquivel told the AP. "It makes us angry, but that's the way it is... We perform our rituals in patios, in fields, in vacant lots, wherever we can." Francisco de Anda, press director for the government's National Institute of Anthropology and History (INAH), offers two reasons for the ban: "In part it is for visitor safety, and also for preservation of the sites, especially on dates when there are massive numbers of visitors... Many of the groups that want to hold ceremonies bring braziers and want to burn incense, and that simply isn't allowed."

Grist notes a Dec. 12 report on Nature:

Cold temperatures have kept crabs out of Antarctic seas for 30 million years. But warm water from the ocean depths is now intruding onto the continental shelf, and seems to be changing the delicate ecological balance. An analysis by [marine ecologist Craig] Smith and his colleagues suggests that 1.5 million crabs already inhabit Palmer Deep, [a] sea-floor valley… And native organisms have few ways of defending themselves. "There are no hard-shell-crushing predators in Antarctica," says Smith. "When these come in they’re going to wipe out a whole bunch of endemic species."

The US National Intelligence Council (NIC) has issued a new report, "Global Trends 2030: Potential Worlds," that emphasizes the rise of China and the risk of catastrophic climate change. An Associated Press summary Dec. 10 says the report finds global terrorism will recede along with the US military footprint in Iraq and Afghanistan, but cyber-attacks will be a growing concern. "The spectacular rise of Asian economies is dramatically altering...US influence," said NIC chairman Christopher Kojm. While the report sees the potential for US-China cooperation on global security, it also warns of resource struggles leading to instability. Under the heading "Stalled Engines," in the "most plausible worst-case scenario, the risks of interstate conflict increase," the report said. "The US draws inward and globalization stalls." The section "Black Swans" foresees extraordinary events that can change the course of history—such as a severe pandemic that could kill millions in a matter of months, or more rapid climate change. The report is optimistic, however, on the prospects for US energy independence. "With shale gas, the US will have sufficient natural gas to meet domestic needs and generate potential global exports for decades to come," it predicts.
