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.

As Mexico has aggressively militarized its "drug war" over the past years, the nation's capital has been an exception, with authorities reluctant to send soliders to patrol the seat of federal power—until now. Over 1,000 army troops have been mobilized to the streets of Nezahualcóyotl, a suburb of Mexico City, just south of the Federal District line in México state, which has seen a dramatic increase of violence in the past weeks. The México state Prosecutor General says 119 assassinations have been registered so far this year, mostly in Nezahualcóyotl. The decision to send in army troops—under a program dubbed "Operation Neza"—was apparently sparked by the Sept. 16 stabbing death of México state lawmaker Jaime Serrano Cedillo of the Institutional Revolutionary Party (PRI). Although subsequent reports have indicated he was killed by his wife in a domestic dispute, Serrano was the second PRI politician killed in as many days last week. On Sept. 15, Eduardo Castro Luque, newly elected to the Sonora state legislature, was shot full of nine bullets in front of his home in Ciudad Obregón. The twin slayings came when the country was on high alert for Independence Day celebrations, with extra troops deployed to conflicted states to head off terror attacks on the festivities. The PRI, a once-entrenched political machine, returns to power after 12 years in opposition, when president-elect Enrique Peña Nieto takes office in December.
