Political killings, the subject of this study, raises the problem of marginalization, neglect and even trivialization of this social phenomenon. The study examines the fundamental reasons for the marginal or inadequate treatment of political killings. Indeed, why are political killings treated in a lax, even unpunished or unresolved manner? This study in its early response is based on the assumption that the assertion of the separation of judicial and executive powers is betrayed by certain facts, hence the selective or biased treatment of political killings, hence the crisis of confidence Ivorian criminal justice system. The methodology adopted for this study highlights the field of study, the survey population and the survey sample, the techniques of data collection as well as the methods of quantitative and qualitative analysis of the data. The study on criminally unsolved political killings has led to results: violation of legal provisions in relation to the facts, and the crisis of confidence.
