摘要
近年来,犯罪分子作案水平不断提高,主动有意识地破坏犯罪现场等反侦查现象正不断出现,而传统的现场勘查工作思路主要是注重对现场有限的有形痕迹物证进行提取和鉴定,这也是当前公安机关因现场提取不到有用的痕迹物证而导致一些案件难以侦破的重要原因之一。犯罪现场所寓含的犯罪信息十分丰富,除了那些有形的痕迹物证外,还包括很多潜在的隐性犯罪信息。获取犯罪现场的犯罪信息需要利用先进的科学仪器设备,更需要发挥人的主观能动性。
In recent years, criminals have been constantly improving their conduction, and the anti - detection to positively and consciously destroy criminal spot is frequently seen, while the traditional way of thinking of on - the - spot reconnaissance mainly attaches importance to the limited spot tangible material evidence of trace to be collected and authenticated, as is also one of the important reasons why nowadays public security organs find it difficult to detect and solve some cases just because they can collect no useful trace evidence. The crime information contained on crime spot is very rich, including not only the tangible material evidence of trace but also much potent hidden crime information. Acquiring the crime information on the criminal spot needs to take the advantage of advanced scientific instrument, and more importantly, to give a full play of human being's subjective initiative.
