People take part in a rally in support of the 43 students of the Normal Rural School of Ayotzinapa that went missing in Iguala, Guerrero, in the Zocalo of Mexico City, capital of Mexico, on Nov. 30, 2014. Mexican President Enrique Pena Nieto announced Thursday a 10-point reform bill that will unify Mexico's multi-layered police forces and stop collusion between government officials and local gangs, a move to defuse nationwide anger over the abduction and possible massacre of 43 students.
