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 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.
Today all Mexico resounds with the cry "They took them alive, we want them back alive". If the 43 are ever found, and they are dead (why and where would their abductors be hiding them?), all hell may break loose. Are the president and his cabinet ready for a major upheaval? Police, politicians and judges have been bought off or put into office by the cartels. Mexicans are fed up with living in a pervasive state of corruption and impunity.
