There are different types of criminological theories which cause fundamental changes in this field of science. This improvement amounts to formation of various criminal policies through criminological schools from classic and positivism to social defense and new neo- classicism which have had different approaches from offender's free will to constrained one and from rehabilitation to repression. Since the early 1970s, a new trend of criminological developments has emerged based on a critical and radical approach that, within the context of deconstruction, sought to shape a modern form of doctrinal punishment. This issue fueled the security-oriented and then populist currents resulting from political attitudes and behaviors, and subsequently provided the grounds for the emergence of a neoclassical criminological discourse based on purposeful and legalistic rigor and a kind of meritorious justice. Therefore, the present study seeks to answer this fundamental question by explaining the security-oriented and populist concepts of criminal policy and how to intervene and create a context for drawing a rethought neoclassical perspective: What are the conditions for the performance and generalization of the concept of implementing neoclassical criminological discourse from the perspective of creating the context for the two aforementioned approaches? The research findings indicate the direct and undeniable impact of the security-oriented and populist approach to criminal policy, emphasizing a kind of reform of the law and stratagem in criminal policy-making to shape the new trend of criminology, and that this change in practice in the practical application of theories may have serious implications for the overall structure of criminal law in terms of gross violations of the fundamental principles of human rights and the limitation of the scope of fundamental freedoms, which points to the re-formation of the new neoclassical discourse.
