Mexico's Federal Police are being accused of another extrajudicial killing. The current issue of Proceso magazine disclosed through autopsy reports and accounts by dozens of eyewitness that federal police killed 16 residents of Apatzingan, Michoacan on January 6. The residents, members of a local Self-Defense Militia that had the green light from authorities to hunt down drug kingpins in the area, were in the city square demanding funds for their work. Authorities initially claimed the deaths occurred as a result of cross-fire or friendly fire. The Apatzingan killings, together with other recent high profile cases such as the enforced disappearance of the 43 Ayotzinapa students or the military murder of 22 civilians in the municipality of Tlatlaya, State of Mexico, has promoted the government's National Security Commission to order an investigation to determine whether law enforcement is using undue force.
