By now we've all heard. Gunmen today shot dead 12 people at the Paris office of French satirical magazine Charlie Hebdo, apparently while shouting "Allahu Akbar" and "We have avenged the Prophet Muhammad!" Editor Stephane "Charb" Charbonnier is among the dead; he had received death threats in the past and was living under police protection. Charlie Hebdo’s offices were bombed in 2011, after the magazine released an issue in which the Prophet Muhammed was satirically billed as "guest editor." The issue included cartoons lampooning Muhammed and was redubbed "Charia Hebdo," a reference to Shariah law. The new attack is said to be the deadliest in France since 1961, when rightists who opposed Algerian independence bombed a train, killing 28 people.

Police agents in San Fernando in the northeastern Mexican state of Tamaulipas aided Los Zetas drug gang in carrying out massacres of hundreds of Central American migrants and others in 2010 and 2011, according to a partially redacted document declassified by Mexico's Attorney General's Office (PGR). Although collusion between local Tamaulipas police and criminal gangs was already well known—US diplomatic cables released by the US government in 2013 discussed it, and locals refer to the police as "polizetas"—this is first time that the PGR has been required to release a document from an ongoing criminal investigation. Previously federal prosecutors had insisted that Mexican freedom of information laws didn't apply to open investigations. The document is now available on the website of the Washington DC-based National Security Archive, along with other relevant documents, including reports from US government agencies and US diplomatic cables released by the WikiLeaks group.

An arsonist set fire to a mosque in the Swedish town of Eskilstuna Dec. 25, injuring five people. Some 20 worshippers were attending midday prayers when the fire broke out. Police said the blaze began when assailants hurled an incendiary device through a window of the mosque, on the ground floor of a residential building. The attack comes amid a fierce debate in Sweden over immigration policy. The far right wants to cut the number of asylum-seekers allowed into Sweden by 90%. On Dec. 3, the anti-immigrant Sweden Democrats brought down the minority governing coalition after it had been in power for just 10 weeks, refusing to support its proposed budget and forcing a special election. The new election is scheduled for March. (BBC News, Al Jazeera, Dec. 15; EurActiv, Dec. 18; Daily Mail, Dec. 3)

Spain's conservative-led parliament, the Cortes, passed an anti-protest bill on Dec. 11 despite harsh criticism from opposition politicians and activist groups, who say it violates the right to demonstrate, limits freedom of expression, and gives undue power to police. The measure, dubbed the "Ley Mordaza" (Gag Law), limits demonstrations to officially permiited gatherings and imposes heavy fines on unauthorized protesters. It also bans taking photos of police during protest demonstrations. Spain has seen a rising tide of mostly peaceful street protests and strikes against Prime Minister Mariano Rajoy's austerity program, which includes harsh cuts to public health and education.

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.

Two volunteers who helped feed Central American migrants passing through Mexico were shot dead on Nov. 23 while talking in their car near the house where they lived in Huehuetoca, México state, according to human rights defenders speaking at a Nov. 26 press conference. The victims were identified as Adrián, a local resident who described himself as a transvestite, and Wilson, a Honduran migrant who was granted a humanitarian visa by the government in November after testifying to the Assistant Attorney General's Office for Special Investigations on Organized Crime (SEIDO). Human rights defenders asked the media not to use the volunteers' last names in order to protect their families.

The Inter-American Development Bank (IADB) hosted a special event on Nov. 14 in Washington, DC to present a plan that El Salvador, Guatemala and Honduras—Central America's "Northern Triangle"—are proposing as a response to the spike earlier this year in immigration to the US by minors from their countries. The "Plan of the Alliance for Prosperity in the Northern Triangle: A Road Map" was originally released in September and is similar to programs announced at a July summit in Washington. However, the IADB event, with US vice president Joseph Biden and the three Central American presidents in attendance, "was the real 'coming out' party for the proposals," the DC-based Center for Economic and Policy Research (CEPR) wrote in its "Americas Blog."

The UN Committee Against Torture has urged the US (PDF) to begin prompt, impartial investigations into all cases of police brutality and excessive use of force by police officers, and to limit the use of electrical discharge weapons. The committee expressed concern over the use of force against people of "certain racial and ethnic groups, immigrants and LGBT individuals, racial profiling by police and immigration offices and growing militarization of policing activities." The committee especially cited reports that the Chicago Police Department has harassed, racially profiled and used excessive force on African American and Latino youths. In particular, the report "expresses its deep concern at the frequent and recurrent police shootings or fatal pursuits of unarmed black individuals."
