三、Reading Comprehension Police departments have placed a great emphasis on reducing response time in the belief that it would increase the probability of arrest. However, several studies found that rapid response had little effect on clearance rates. Only about 3 percent of crimes are reported while in progress; thus rapid response to most calls does not increase the probability of arrest. The problem is that police departments have no control over two key elements between the time a crime is committed and the time a police officer arrives on the scene: the interval between the commission of a crime and the time it is discovered; and the interval between discovery and the time the citizen calls the police. Most crimes are discovered after the fact, and even in the most “involvement” crimes – i.e., where the victim is present (e.g., assault) – there is some delay between victimization and the subsequent call to the police.
