TL;DR: In this article , the characteristics of four high and four low-performing police agencies, as measured by their long-term crime clearance rates, were analyzed through a systematic assessment of 30-years of clearance rates of robberies, aggravated assaults, burglaries, and homicides for the largest 100 police departments in the United States.
Abstract: This eight-agency case study analyzes the characteristics of four high-and four low-performing police agencies, as measured by their long-term crime clearance rates. High and low performers were identified through a systematic assessment of 30 years of clearance rates of robberies, aggravated assaults, burglaries, and homicides for the largest 100 police departments in the United States. Researchers then conducted in-depth case studies of eight of these agencies—four of the highest and four of the lowest ranking in terms of their investigative practices. Comparisons of high-and low-performing agencies reveal differences in organizational structure; leadership and resources; selection, training, and performance review for investigators; case assignment and investigative processes; and community interactions. These findings provide direct guidance to agencies seeking to strengthen their investigative organization and practices.
