公安训诫是对情节轻微、尚不足以依据《治安管理处罚法》处罚的行为进行的类似于批评教育的劝诫措施，其在功能与目的上与行政处罚中的“警告”具有相似性但缺乏救济途径，这些现实矛盾给滥用公安训诫提供生存土壤。判断训诫是否为行政处罚，不仅仅看其外在表现形式，还要结合其内容、法律依据及目的等综合判断，正确认定公安训诫的真实法律性质。此外，公安训诫是否属于行政处罚措施，是否属于行政案件受案范围，这些都应通过个案考察训诫书中所载内容是否给行政相对人的权利义务造成实际影响进行分析。

Public security admonition is an admonition measure similar to criticism and education, which is carried out for minor offences that are not serious enough to be punished according to the Public Security Administration Punishment Law. Its function and purpose are similar to the "warning" in administrative punishment, but there is no relief channel. These realistic contradictions provide space for abusing public security admonition. Whether the admonition is an administrative punishment depends not only on its external manifestation, but also on its content, legal basis and purpose. In addition, whether the public security admonition is an administrative punishment measure and whether it belongs to the scope of administrative cases should be analyzed through case study. One important factor is whether the contents in the admonition have actual influence on the rights and obligations of the administrative counterpart.
