The government is now afraid to use public force to prevent demonstrators from blockading roads and streets, stealing buses and trucks, ransacking supermarkets and torching government buildings. President Peña Nieto has claimed that his patience has limits, but so far the Ayotzinapa movement appears to have forced him into a corner.
The mood in Mexico is so depressing that even Elena Poniatowska, the novelist-journalist who chronicled the 1968 massacre of students in Tlatelolco, feels a chill when she talks about the murder of 43 students in Ayotzinapa, who were found burned to death in a municipal trash dump. At 82, Poniatowska keeps on exposing social injustice in Mexico in memorable books like Here's to You, Jesusa, Nothing No One: The Voices of the Earthquake and thousands of journalistic articles in newspapers and magazines all over the world. This year, she won the prestigious Premio Cervantes, the equivalent of the Nobel for Spanish language writers.
The impunity enjoyed by some has tarnished the police, prosecutors and politicians as a whole, whether honest or dishonest. To prevent another Iguala -- or another Villas de Salvárcar or another San Fernando -- Mexican leaders must show that rule of law prevails, especially for those required to uphold it.
