Abstract A nationwide survey of U.S. law enforcement agencies was conducted by Horvath et al. (2001) with an aim of describing comprehensive information about police practices and policies regarding the criminal investigation process. Using the survey results, this study explores whether and how police organizations vary in their ability to clear crimes by examining organizational policies and practices that can predict cleared crimes against persons and property. The study’s results reveal, contrary to the conclusions of the RAND Corporation’s landmark 1977 report on police criminal investigations, that certain organizational characteristics of “crime control” efforts, including the police department’s perceived importance of clearance rates, cold case units, detachment from the public, case screening methods, Automated Fingerprint Identification System ownership, the use of “team policing”, and members of task forces were effective, but that those with a more “due process” orientation such as education requirements for investigators and their supervisors, prosecutor consultation, and problems with prosecutors’ advice tended to inhibit the clearing of cases. Implications for the effectiveness of police organizational policies related to the criminal investigation process are discussed.

警察政策和做法如何影响成功的犯罪调查：使警察部门能够“清除”犯罪的因素

摘要 Horvath 等人对美国执法机构进行了全国性调查。(2001) 旨在描述有关刑事调查过程中警察实践和政策的综合信息。本研究使用调查结果，通过检查可以预测针对人员和财产的犯罪已被清除的组织政策和实践，探讨警察组织在清除犯罪的能力方面是否以及如何变化。该研究的结果显示，与兰德公司 1977 年具有里程碑意义的警察刑事调查报告的结论相反，“犯罪控制”工作的某些组织特征，包括警察部门认为清案率的重要性、冷案单位、脱离公众, 病例筛选方法, 自动指纹识别系统的所有权、“团队警务”的使用和工作队成员是有效的，但那些更注重“正当程序”的人，例如对调查人员及其主管的教育要求、检察官咨询以及与检察官的问题' 建议往往会阻碍案件的结案。讨论了与刑事调查过程相关的警察组织政策的有效性的影响。
