谈警务技战术教师的“务”与“技”

警务技战术,是建立在良好身体素质基础上的通过训练形成的合理的克敌制胜的方法。警务技战术训练既是能力、技巧和策略的训练,也是执法水平的训练和塑造人民警察形象的训练。公安院校是培养公安后备人才、提高人民警察自身素质、加强公务队伍建设、进行警讯国际交流的重要阵地。警务技战术教学在公安院校教学中占据相当重要的地位,公安院校学员对警务技战术的学习也非常重视,同时警务技战术教师既是人民教师又是人民警察,这就要求警务技战术教师要具有较好的技战术素质,正确处理好＂务＂与＂技＂的关系。     

Implementation and Optimization of the Sodium‐Rhodizonate Method for Chemographic Shooting Distance Estimation

In shooting incident investigations where it is important to estimate the shooting distance, the sodium‐rhodizonate coloring method has been used for the visualization of GSR patterns extensively. This publication describes the optimization of this method by the use of a heated press for the transfer of GSR traces on garments, as well as variation of a number of other important process parameters. Our final aim for this project was to prepare a formal validation of the coloring method as prerequisite for its inclusion into the scope of ISO17025‐certified methods in the GSR Laboratory. A number of important factors and process parameters were identified, such as buffer composition and pH, type of textile used as a substrate and resolution of the documentation of the results. Results were tested using a synthetic proficiency test. Our optimized method has been found to be a very effective technique for visualization of macroscopic GSR traces.

略论警务技战术训练之意义

警务技战术训练是针对我国全面建设小康社会关键时期社会治安形势及其基层和一线公安机关警务实战行动的特点,以提高公安民警保护人民、惩治和制止犯罪、维护社会治安稳定的能力为主要目的,以依法妥善处置各种突发性紧急情况时的基本处理手段、程序和方法为重点内容的训练。强化警务技战术训练对提高公安机关的实战能力、完善训练制度、提高训练效果、改善训练条件、减少不必要的伤亡有着重要意义,是培养应用型和实战型警务人才的必备环节。     

Accuracy and Repeatability of Trajectory Rod Measurement Using Laser Scanners

Three‐dimensional (3D) technologies contribute greatly to bullet trajectory analysis and shooting reconstruction. There are few papers which address the errors associated with utilizing laser scanning for bullet trajectory documentation. This study examined the accuracy and precision of laser scanning for documenting trajectory rods in drywall for angles between 25° and 90°. The inherent error range of 0.02°–2.10° was noted while the overall error for laser scanning ranged between 0.04° and 1.98°. The inter‐ and intraobserver errors for trajectory rod placement and virtual trajectory marking showed that the range of variation for rod placement was between 0.1°–1° in drywall and 0.05°–0.5° in plywood. Virtual trajectory marking accuracy tests showed that 75% of data values were below 0.91° and 0.61° on azimuth and vertical angles, respectively. In conclusion, many contributing factors affect bullet trajectory analysis, and the use of 3D technologies can aid in reduction of errors associated with documentation.     

Controversial Suicide Case Using a Submachine Gun with a Sound Suppressor—The Need of Team Work of Forensic Chemistry and Firearm Examiners

Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X‐ray microanalysis, and infrared spectroscopy. The shooting distance was assessed to be 30 cm or more, whereas the greatest distance that could have been achieved by the victim himself was about 11–13 cm. The obtained results supported the version of homicide rather than suicide.     

司法警察类院校开设警务技战术课程刍议

警察警务技战术教学与研究是现代警务教学与研究的重要内容之一。警务技战术课程应包括：体能训练、警察防卫与控制技术、射击、警务战术四个部分。提高监狱人民警察警务技战术能力,在司法警察类院校开设警务技战术课程十分必要。     

Alessandro Orsini. Anatomy of the Red Brigades: The Religious Mind-Set of Modern Terrorists

ABSTRACT

Those who study terrorism are familiar with the claim that suicide attacks are the most lethal form of terrorism today. Suicide attacks kill more people on average than non-suicide attacks, thereby justifying why terrorist organizations use this costly method of attack and explaining in part why suicide tactics have proliferated. However, extant empirical support for this claim is largely insufficient, focusing only on macro-level analysis of lethality data. Using data from the Global Terrorism Database, this study examines variation in lethality among suicide and non-suicide attacks based on geographic location, attack type, and target/victim type. It also introduces a new metric—the lethality ratio—to measure costs and benefits of attacks in terms of lives lost. It finds that, although suicide tactics are generally more lethal than non-suicide tactics, they also come at greater costs to the organization. This analysis also finds behavior that is inconsistent with the premise that terrorist groups are focused on maximizing lethality while reducing costs in all cases; that despite certain advantages, suicide attacks may remain a suboptimal tactic from the perspective of the terrorist group; and that additional criteria may help explain why suicide tactics are used.
