随着市场经济的建立,公私财物的复杂性、交叉性,以及人员流动性的进一步加大,我国放火案呈上升趋势,但放火案破案难度较大,因为火灾本身有很大的破坏性,物体因被烧而变形或被熏,使现场面目全非,加之灭火行动、抢救人员、搬运物资不可能会顾及现场保护,造成人为对现场原貌破坏严重。同时,由于放火犯实施犯罪的多样化,放火手段的隐蔽性,放火物的复杂化,加之放火往往在深夜,目击证人少,所以在实施破案中,很难提取到有价值的痕迹物证。为有效扼制放火犯罪,加强对放火案的调查和研究,对做好消防工作和打击犯罪都有十分重要的意义。
With the establishment of a market economy and the complexity and cross-over of public and private property as well as the further increase of the mobility of personnel, the arson case in our country is on the rise. However, it is more difficult to solve arson case because the fire itself is very devastating. Objects were burned and deformed or smoked, so that the scene beyond recognition, combined with fire fighting operations, rescue workers, handling materials can not take into account on-site protection, resulting in man-made destruction of the original scene. At the same time, it is difficult to extract valuable evidence because of the diversification of crimes committed by arsonists, the concealment of means of arson and the complicity of arson. In addition, there are few witnesses to arson in the middle of the night. In order to effectively curb the crime of arson and strengthen the investigation and study of arson, it is of great significance to fire prevention work and crime prevention.
