On June 6 a criminal court in Geneva, Switzerland, sentenced Erwin Sperisen ("El Vikingo"), Guatemala's national police chief from 2004 to 2007, to life in prison for his participation in the extrajudicial execution of seven inmates in 2006 during a police operation at the Pavón prison near Guatemala City. Swiss authorities had detained Sperisen, who holds dual Guatemalan and Swiss citizenship, in August 2012 in response to arrest orders Guatemala issued in 2010 following an investigation by the United Nations-sponsored International Commission Against Impunity in Guatemala (CICIG). Under Swiss law citizens cannot be extradited, but they can be tried in Switzerland on foreign charges. The Geneva court acquitted Sperisen of three other charges due to lack of evidence; these concerned the killing of three escaped prisoners in October 2005. One of the former police chief's lawyers said the defense would appeal the convictions in the Pavón case.

Swiss prosecutors announced Aug. 31 that Erwin Sperisen, former commander of Guatemala's National Civil Police, was arrested in Geneva. The arrest is based on evidence submitted in 2011 by Guatemalan authorities linking Sperisen to extrajudicial killings. Sperisen, 42, holds both Swiss and Guatemalan nationalities; because of his Swiss citizenship he cannot be extradited, but authorities say he will be put on trial in Switzerland. He is accused in at least 10 homicides carried out in Guatemala's prison during his time as police commander from 2004 to 2007, thought to be part of a campaign of "social cleansing."

Hundreds of anarchists from all over the world gathered Aug. 8-12 in the town of Saint-Imier in the Jura region of Switzerland to mark the 140th anniversary of a congress which saw the anarchists break with the workers' movement dominated by Karl Marx. The International Anarchism Gathering called for public protests and strikes to oppose austerity measures imposed in response to the European debt crisis. "Capitalism goes from crisis to crisis, so this is an opportunity for us," said Aristides Pedraza, one of the event organizers.
