Fragment extracted from the text: "Ayotzinapa", by Elena Poniatowska.
"The tragedy of Ayotzinapa has highlighted the thousands of cases that have not been investigated. In his essay published in El País on 30 October 2014, Juan Villoro wrote: ‘Mexico is united in indignation and there is an angry clamour for things to change… the Mexico of the armed forces is afraid of those who teach literacy,’ because a literate country is one that can demand and denounce. A literate country can be disobedient. Real students on the marches do not make use of chains, sticks, stones or aggression in order to demand justice. Students act in solidarity, they demand and reclaim what is true, because they know their rights and their responsibilities."
