Corruption is a global phenomenon that takes shape depending on cultural, political and economic formations and manifests itself in various forms. In the statement of the second step of the revolution, the Supreme Leader of the Revolution gave the necessary advices and recommendations in order to spread justice and fight corruption. As corruption is considered a regional and international affair, several documents have been adopted to anticipate anticorruption mechanisms that, given the prevalence and variety of corruptionrelated crimes, could accelerate the realization of the second step of the revolution statement. Therefore, the main purpose of this article is to review the provisions of the recommendations and how to apply and interact with the goals of the Supreme Leader. The present research is based on a descriptive-analytical method and in the form of a library in response to the lack of implementation of recommendations and its national framework in the form of a second step statement. Given the role of the police, as a regulatory body under the executive and judiciary (law enforcement and general and special officers), in the fight against corruption, several components can be effective in improving the functioning of the police: take measures to ensure the effectiveness of investigative authorities, efficient use of traditional and modern research methods, measures to ensure the efficiency of research, protect intuition and evidence, and ultimately reverse the burden of proof. Accordingly, the police and its investigations, before (to prevent the possible occurrence of corruption) and after the discovery of crime (to prevent the spreading deprivation of public trust in the elements of the administrative system), are among the most important criminal responses to corruption. The importance of the investigation phase, given the complexity and sometimes transnational nature of corruption, doubles the need to adhere to international instruments, including the Merida Convention. Therefore, for the research and efficiency of the monitoring devices and their determination in line with the statement of the second step of the revolution, it is necessary to update the research methods and functionalism and sometimes to deviate from the previous traditions of obtaining evidence.
