The principle of acquittal in criminal law plays a fundamental role in defending the rights of the accused, but the absolute nature of the said principle in the face of some crimes such as disciplinary and security crimes is one of the important challenges that is the subject of debate. The purpose of this article is to examine this important question, what is the status of the principle of innocence in security and law enforcement crimes from a jurisprudential and legal point of view? The findings indicate that despite all the interpretations of the original principle of innocence, it is not absolute and unconditional, despite the application of the principle of innocence in criminal matters and its ruling over other principles and rules of criminal law, in certain cases, the application of this principle is avoided. The basis of deviation from the principle of innocence in many cases is the same basis that justifies the rule of the principle of innocence in criminal matters. In this way, the principle of acquittal towards the accused is distorted, and as a result, despite the lack of conclusive evidence, the judge resorts to exceptional methods of proceedings, including obvious cases of resorting to exceptional methods of proceedings in Islamic criminal law can be found in the cases of law and order and public security. As a result, the evidence of guilt takes precedence over the principle of innocence.
