In Mexico, the country’s National Human Rights Commission has said federal police killed at least 22 people on a ranch last year before moving the bodies and planting guns to support the official account that the deaths happened in a gun battle. One police officer was killed in the confrontation, which took place in the state of Michoacán. Federal police have been implicated in other mass killings in the past two years. The government has said the dead were suspected members of a drug cartel. The commission said officers also tortured at least two suspects.
