Amnesty International (AI) on Feb. 10 urged the Taiwanese authorities to "drop criminal charges against people solely for participating in or organizing peaceful demonstrations...after more than 100 people were charged for protesting during the so called "Sunflower Movement." AI claims that while the students and activists involved in the movement are being charged, the "police and politicians who may have carried out human rights abuses ... get away without any...investigation." They assert that it is a fundamental right to be able to demonstrate peacefully, and that "the peaceful intention of organizers...must be presumed unless there is compelling...evidence that [they] intend to use, advocate or incite imminent violence." According to AI, these actions on behalf of the authorities, in line with the Parade and Assembly Act , are in violation of the International Covenant on Civil and Political Rights (PDF), formally adopted by Taiwan in 2009.

The nonprofit Argentine Forensic Anthropology Team (EAAF) released a report on Feb. 7 citing a number of irregularities in the Mexican federal government's investigation of the disappearance of 43 teachers' college students in Iguala de la Independencia in the southwestern state of Guerrero the night of Sept. 26-27. The Argentine experts have researched deaths and disappearances in about 30 countries, including those that occurred in their own country during the 1976-1983 "Dirty War" against suspected leftists and in Guatemala during that country's 1960-1996 civil war. The Argentines were brought into the investigation by the parents of the missing students, who had attended the traditionally leftist Raúl Isidro Burgos Rural Teachers' College in the Guerrero town of Ayotzinapa.

At least seven were injured, some seriously, on Jan. 12 when dozens of protesters tried to enter a Mexican military post in Iguala de la Independencia, Guerrero state, saying they were looking for students who were abducted in the area the night of Sept. 26-27. The missing students had attended the Raúl Isidro Burgos Rural Teachers' College in the town of Ayotzinapa, and the protesters were other students from the school and parents and relatives of the missing youths. The military post, staffed by the 47th Infantry Battalion, is near the sites where local police and other—possibly including soldiers and federal police—gunned down six people and abducted 43 students in the September violence. So far authorities have only identified the remains of one of the missing students, leaving 42 unaccounted for.

Facing serious political and economic problems at home, on Jan. 6 Mexican president Enrique Peña Nieto made his first official visit to Washington, DC, since taking office in December 2012. A private meeting at the White House with US president Barack Obama lasted longer than was scheduled, and the two presidents didn't take questions when they spoke with the press afterwards. The US has been following the "tragic events" involving seven deaths and the abduction of 43 students the night of Sept. 26-27 in the southwestern Mexican state of Guerrero, Obama told reporters, and the US would continue to aid in investigations and in the fight against drug cartels. Obama also praised Mexico's efforts to keep Central American migrants from reaching the US border, especially during the child migrant "crisis" in the summer of 2014. Peña Nieto promised that Mexico would help the US and Cuba normalize relations. (La Jornada, Mexico, Jan. 7)

On Dec. 13 the left-leaning Mexican news magazine Proceso published an investigative report challenging the government's account of the abduction of 43 students and the killing of three students and three bystanders the night of Sept. 26-27 in Iguala de la Independencia in the southwestern state of Guerrero. Based on cell phone videos, interviews, testimony by witnesses and leaked official documents, the report's authors, Anabel Hernández and Steve Fisher, claim that agents of the Federal Police (PF) were involved in the attack on the students, that the Mexican army was at least complicit, and that the administration of President Enrique Peña Nieto has been covering up the role of federal forces.

Hundreds of Mexican immigrants and other activists held actions in at least 47 US towns and cities on Dec. 3 to protest the abduction of 43 teachers' college students by police and gang members in Mexico's Guerrero state in September; each of the 43 students had one of the actions dedicated to him. The protests were organized by UStired2, a group taking its name from #YaMeCansé ("I'm tired now," or "I've had it"), a Mexican hashtag used in response to the violence against the students, who attended the Raúl Isidro Burgos Rural Teachers' College in the Guerrero town of Ayotzinapa. The protesters focused on US government financing for the Mexican government—especially funding for the "war on drugs" through the 2008 Mérida Initiative—but they also expressed outrage over the US court system's failure to indict US police agents in two recent police killings of unarmed African Americans.

On Nov. 20 tens of thousands of protesters marched through downtown Mexico City in the fourth National and Global Day of Action for Ayotzinapa, demanding the return of 43 missing students from the Raúl Isidro Burgos Rural Teachers' College, located in Ayotzinapa in the southwestern state of Guerrero. The students were abducted the night of Sept. 26-27 in the Guerrero city of Iguala de la Independencia, apparently in a joint action by municipal police and local drug gangs; three other students were killed in the incident, along with three bystanders. The Nov. 20 demonstration, which also marked the official anniversary of the start of the 1910 Mexican Revolution, coincided with the arrival in the capital of three caravans led by parents of the missing students; the parents had spent a week traveling through different parts of Mexico to increase public awareness about the disappearances.

Two students were wounded on Nov. 15 at the campus of the National Autonomous University of Mexico (UNAM), in the Coyoacán section of the Federal District (DF, Mexico City), when a police agent fired his pistol at a group of youths. Witnesses said the incident started when two men from the DF judicial police and two women from the DF prosecutor's office arrived in a car and began photographing students near the Che Guevara Auditorium; student activists have been meeting in the auditorium to plan actions protesting the killing of six people and the abduction of 43 teachers' college students in Iguala de la Independencia in the southwestern state of Guerrero the night of Sept. 26-27. When a group of students challenged the four officials, one of the two agents responded by assaulting a student and then firing his pistol at the ground. The same agent fired again, several times, as all four officials fled the campus on foot, pursued by a group of students. The shots wounded one student in the foot and grazed another student's knee; a dog was also injured.
