Quantitative research is generally preferred, but sometimes it is difficult to know which interventions are mainly responsible for changes in particular statistics, such as a crime rate decreasing over a period of time

Besides just looking at the numbers, how could a police department obtain information on what works?


Often qualitative information is extremely helpful in evaluating what works. A helpful strategy for police departments is self reporting from the criminals themselves. Although some apprehended criminals may choose not to disclose much information, a surprising number of criminals will confess and then give a wealth of information to police. The key is for the investigator to ask. Many types of crimes are now better understood because of self reporting, including pedophilia, sexual assault, and serial killing. The learned information is utilized in theory development, profiling, and crime control. Numbers alone can't give the kind of information that is needed for external validity (relating what works in one place with what might work in other places or with other crimes).
