Mexico’s human rights body said Tuesday Dec. 17, 2013 the government shouldn’t be allowing the formation of vigilante groups in some parts of Mexico where people have risen up to battle drug gangs. It says they could lead to more violence and undermine the rule of law. (AP Photo/Dario Lopez-Mills, File)
