In our society, does violence grow or does our sensitivity about it grows?, ask the historians Mary Del Priore and Angélica Müller. Throughout its 16 chapters, each of them composed of independent articles that orbit the universe of violence, this book does not intend to show a chronology of crimes and violence in Brazil, "but invite readers to reflect on the forms of infractions that are part of our daily lives, hoping that our society will find new forms of tolerance, coexistence and solidarity.”
