This book aims to analyze the crimes against human rights that offended the Democratic Rule of Law in Brazil, committed by state agents in the Brazilian military dictatorship (1964/1985), asserting that they remained unpunished. In view of this, to address this issue, it is proposed that criminal offenders be held liable. The issue of our slow Transitional Justice will also be examined, arguing for the criminal prosecution of state agents who violated human rights in Brazil, demonstrating how and how this can occur, all in order to move away from impunity, hitherto guaranteed by the Brazilian Amnesty Law, ensuring the effectiveness of justice and the strengthening of democracy.
