Mexico is a country beset by violence and insecurity, with 98 percent of violent crimes unsolved and 94 percent of crimes unpunished.These staggering statistics illustrate the critical need to understand the history of Mexico’s penal law and justice system, from its evolution and development to its public image and effects on Mexican society. In A Question of Justice Elisa Speckman Guerra elucidates Mexico’s penal law and justice system in the twentieth century from the disciplinary perspectives of both history and law.Looking at the critical period from 1929 to 1971, Speckman Guerra investigates the democratic rule of law and to what extent it was followed within the justice system, as well as judicial proceedings considering the role of gender, class, and race.For that reason, Speckman Guerra also delves into homicides involving very well-known victims, like the famous singer Guty CÁrdenas, and notorious murderers, such as the Olympic medalist Humberto Mariles; the public image of police, judges, defendants, lawyers, and other actors involved in penal processes; and the representations of crime and justice in print and on film.This extensively researched study illuminates the evolution of Mexico’s penal laws, institutions of justice, and sensationalist media and violence, thereby addressing issues that are critically relevant today.
