On Dec. 9 Mexican authorities released 56 of the 69 people who had been in detention for more than a week on suspicion of "attacking public peace" during protests in Mexico City against the inauguration of President Enrique Peña Nieto. A total of 106 were reportedly arrested on a day that included violent confrontations between police and protesters and widespread property destruction, but 28 were quickly released. Judge María del Carmen Mora Brito of the Federal District (DF) court system ordered the Dec. 9 releases after "analyzing videos, testimonies and expert witnesses' reports," the DF Superior Court of Justice (TSJDF) announced in a communiqué.

Protests against Mexican president Enrique Peña Nieto during his inauguration on Dec. 1 quickly turned into violent confrontations between police and demonstrators that disrupted much of downtown Mexico City. The protests were called by the National Convention Against the Imposition, a coalition of groups holding that Peña Nieto's election last July was manipulated, and #YoSoy132 ("I'm number 132"), a student movement that arose in the spring in response to the election campaign. But masked youths, many of them wearing black t-shirts with anarchist symbols, quickly became the center of attention at the Dec. 1 demonstration.

Juventina Villa Mojica, an environmental activist in the village of Coyuca de Catalán, in Mexico's southern state of Guerrero, was murdered along with her 10-year-old son on Nov. 28, in a mountaintop attack by up to 30 gunmen. Villa had ridden in an all-terrain vehicle with her two children up a mountain to get a cellphone signal, as there are no telephones in the village.  Her seven-year-old daughter survived unharmed. State prosecutors report that the ambush took place despite the presence of 10 state police officers who had been assigned to protect her following death threats on Villa and deadly attacks on her family members. Manuel Olivares Hernández, director of the local Centro Morelos human rights group said Villa was targeted by narco gangs for her efforts to protect the forest. "It's a virgin area with rich forest areas, and the main interest of drug traffickers is cutting down the trees so that once it is deforested they can expand their drug fields," Olivares said.

A total of 19 bodies have been found in clandestine graves in northern Mexico's Chihuahua state, officials from the state prosecutor's office said Nov. 26. The first 11 were discovered in what was described as a deserted area of La Colorada ranch, in the community of Ejido Jesús Carranza, 40 kilometers southeast of Ciudad Juárez near the Texas border. The bodies were said to be two years old. The victims were asphyxiated, shot or beaten, their ages ranged from 18 to 40 years old, and they included US citizens. Information leading to the discovery came from the US consulate in Ciudad Juárez, Chihuahua authorities said. That same day, eight more bodies were unearthed near Rosales, in Chihuahua's interior. These bodies were just two days old, and bore signs of torture. Some had been burned, beaten and had eyes carved out before being shot in the head. Four more bodies were found along the highway near the mountain outpost of Creel.

Complaints about abuses by Mexican police and soldiers have increased dramatically over the past seven years, according to testimony by Raúl Plascencia Villanueva, the president of the government's National Human Rights Commission (CNDH), to the Mexican Senate's Human Rights Commission on Nov. 21. Plascencia was reporting principally on the period from Jan. 1, 2005 to July 31, 2012, which overlaps the administration of President Felipe Calderón Hinojosa and his militarization of the "war on drugs." Calderón took office on Dec. 1, 2006; he will be succeeded this Dec. 1 by Enrique Peña Nieto.

A study released late last month by the Mexican Institute for Competitiveness, an elite think-tank based in Mexico City, asserted that proposals to legalize cannabis in Colorado, Washington and Oregon could cut Mexican drug cartels' earnings from traffic to the US by as much as 30%. The study, entitled "If Our Neighbors Legalize," drawing on previous research by the RAND Corporation, predicts that legalization in any US state would help drive down the price of high-quality domestic cannabis, undercutting the cheaper and less potent cartel imports. It calculated a loss of $1.425 billion to the cartels if Colorado legalized, $1.372 billion if Washington legalized, and $1.839 billion if Oregon voted yes. (AP, Nov. 1) In the Nov. 6 vote, initiatives calling for legalization of cannabis under regimes of state control were approved by voters in Colorado and Washington, but rejected in Oregon.

The Mexican Senate voted 96-28 on Nov. 13 to approve changes to the 1970 Federal Labor Law (LFT) that will legalize the use of part-time and contract employees, allow the hiring of workers for trial periods, and limit the amount of back pay businesses are required to give laid-off workers. The controversial "labor reform," which had been approved by the Chamber of Deputies the week before, was sent on to President Felipe Calderón Hinojosa, who was expected to sign it into law.

After more than two months of investigation, on Nov. 9 Mexico's federal Attorney General's Office (PGR) confirmed that it was formally charging 14 federal police agents for an Aug. 24 attack on a US embassy van on a road near the Tres Marías community, south of Mexico City in the state of Morelos. The agents claimed they mistook the van's occupants—two agents of the US Central Intelligence Agency (CIA) and a Mexican marine—for members of a gang connected to a local kidnapping. The two CIA agents were wounded in the incident.
