刑事侦察学是一门新兴的应用学科。其应用方面,源远流长,而发展为一门科学,只是近半个世纪的事情。刑事侦察学实践性强,侦察技术手段是侦察学的一个重要方面,案件侦破方法也是侦察学的一个重要方面。人们注重对这些方面的研究,是完全应该的。但是,侦察实践不全等于技术、手段、方法。侦察科学包括着侦察技术、手段等,但不止于此。刑事侦察学涉及到实践与理论的一切方面,其理论研究的起步与发展均远落后于侦察技术、手段等的研究,其前进步伐也较为缓慢。特别是刑事侦察学的基础理论研究更为薄弱, Criminal reconnaissance is a new application discipline. Its application, goes back to ancient times, and the development of a science, only about half a century of things. Criminal reconnaissance is practical and scientific means of reconnaissance is an important aspect of reconnaissance. Case detection is also an important aspect of reconnaissance. People pay attention to these aspects of research, it is entirely right. However, reconnaissance practice is not equal to technology, means and methods. Scouting science includes techniques and means of detection, but it does not end there. Criminal reconnaissance involves all aspects of practice and theory. The starting and development of its theoretical research lags far behind that of reconnaissance techniques and means, and its progress is also relatively slow. In particular, the basic theory of criminal investigation science research is more weak,
