It is still unclear whether the rapid response can be effective in addressing certain crimes. However, some researchers state that it does not matter since it is effective only in 25% of reported crimes. It has been acknowledged that in most cases immediate response is not required as these are discovery crimes while rapid response may be efficient in some involvement crimes. Discovery crimes are those reported a certain time after the crime has been committed and involvement crimes are those reported at the time of the crime occurrence. Notably, discovery crimes are reported several minutes (about 10 minutes) after the crime has been committed and this time is usually enough for the offender to escape the scene. The delay is explained by people’s inner conflict as some people tend to call others to get advice, some try to resolve the issue on their own and some think of possible negative outcomes for all stakeholders involved. Differential police response is the response given by police phone operators who, based on facts provided by the caller, categorize calls and decide whether there is a need in patrol unit dispatch. This strategy is aimed at improving the effectiveness and efficiency of police agencies. At that, effectiveness is the ability to achieve the goal set whereas efficiency is the ability to accomplish certain tasks in the shortest time and with the use of minimum effort, funds, and so on. In theory, effectiveness, as well as efficiency, may be achieved through extensive training and supervision of operators whose major issue is to decide whether the patrol unit is necessary for this or that situation. In the Kansas City study, the researchers focused on the impact preventive patrolling had on the crime rate. The researchers note that the study was effective as it answered the research question (the answer was negative), but it also raised several other questions. The researchers state that there were certain difficulties as it is not easy to create an experimental atmosphere and they also stress that the presence of researchers does not affect the results of the study. The researchers emphasize that they proved that experiments could be held and police operations could be estimated. Larson believes that the researchers concentrated on the effect of the distribution of patrolling units. The author also admits that the study has a profound effect on further research as it is proved that experimental conditions can be maintained. It is still unclear whether a one-officer patrol car is more effective than a two-officer patrol car. However, proponents of dispatch of one-officer cars note that the response time in the former case is shorter. At the same time, supporters of two-officer cars dispatch note that the difference is not significant and the costs are rather considerable. Officers tend to support two-officer car dispatch as in this case they do not have to wait too long for cover. At the same time, administrators often support the idea of the one-officer car as it is associated with a shorter response time. According to the research, there is quite an insignificant difference between the two options, and more variables, as well as regions, have to be included in the further research. It is also necessary to note that in a one-officer car d
