Study On The Basic Problems Of Criminal Investigation Statistics

Since the statistical science was born in the mid-17th century, its strong data analyticalability quickly became the darling of all disciplines. Natural and social science both, regardstatistics as the basis of their self-analysis and application. Criminal investigation in infancyhas been inextricably linked with statistical science, and anthropometric method is theoutcome of the combination of statistical science and Criminal investigation. After Quetelet’sexploratory research, crime statistics had been flourishing in the West, the exchange of crimestatistics between countries is also increasing, which promoted the development of thecriminal investigation statistics. Investigators tend to carry out investigative activities bymeans of crime statistics research, and their investigation process has also become the studyobject of crime statistics, and the two complement each other. In the latter half of the20thcentury, some American scholars with dual background of professional statistics andjurisprudence introduced quantitative analysis into litigation, which not only enriched forensicscience, but also greatly advanced the development of criminal investigation statistics. Inhistory, China has been involved in organization of the United Nations Crime Survey, andChinese law and investigation academia also actively introduced Western crime statisticsmethodology, but there is no scholar specializing in criminal investigation statistics yet.Chinese People’s Public Security University first set the Public Security Statistics course,introducing statistics into public security disciplines and opening up a channels indirectly forthe research of criminal investigation statistics. This article believes that criminalinvestigation statistics has its own theoretical basis and necessity of research. Under thejudical environment relatively in shortage with quantitative analysis, the introduction ofstatistical theory can solve a lot of the difficulties in the course of investigation. Especiallywhen facing a lot of crime information, statistical method is the best technical means todiscover hidden laws and crime clues through data analysis. With the popularity of thecomputer at the same time, by means of statistical software, investigators without statisticaleducational background can also master data analysis methods after simple statistical training.This has laid the foundation of the popularity of Criminal Investigation Statistics. In China,domestic investigation scholars and substantive departments have begun to study criminal investigation statistics, and some results have been achieved, however, as one of thebasic methods of investigation, the functions of detection statistics is far to be enough, whichneeds further improvement.This article is divided into three parts, the main content:The first part is to Criminal Investigation Statistics overview: this briefly describes thedevelopment process of statistics and practical needs for using statistical methods ininvestigation. Then based on the concept of statistics and the characteristics of investigation,the concept of criminal investigation statistics is defined. Purpose, subject, as well as object ofcriminal investigation statistics have also been elaborated, contrastive analysis amongcriminal investigation statistics, crime statistics, judicial statistics, and public securitystatistics has been made, and quantitative analysis value of criminal investigation statistics hasbeen studied.Then history of international and domestic criminal investigation statistics was reviewed,which is followed by a summary of the current status of criminal investigation statistics inChina. First introduced Quetelet’s early research, then analytical criminal investigationStatistics systemic use, for the first time in history. Introduced two major U.S. crime statisticssystem and the cooperation of the international crime statistics. Analysis of crime statisticsand justice statistics of china.At last, there was an introduction of case studies, and empirical study about investigationresearch has been made from aspects of mean value, probability, normal distribution, theMonte Carlo method, and regression analysis, etc. In the mean while, criminal investigationstatistics methods have been summarized. In the conclusion part, recommendations weregiven for the direction of criminal investigation statistics development: we should activelyintroduce statistical techniques and methods from other countries which are moresophisticated, at the same time, statistical thinking should be put in the first place. Whentraining investigators, the most important thing is to establish the correct way to observe thedata, and open up a new statistical model under investigation mode.
