The Kansas City experiment revealed that reducing neighbourhood preventative patrol had little or no impact on crime (option a).
In respect to marked police patrol, the Kansas City Preventive Patrol Experiment was created to evaluate the deterrence theory's presumptions. Researchers were particularly interested in determining whether an increase in police patrols could result in a drop in both crime and public fear of crime.
The South Patrol District in Kansas City was divided into three 'beats' by the researchers, where police patrols would be deliberately changed. Proactive patrols were deployed in the first beat, involving a two- to three-fold increase in police patrols. Reactive patrols were employed on the second beat; no routine patrols were conducted (though officers continued to respond to calls for service). The third beat served as a control beat, with all regular patrols maintained at the same level as before the trial began.
The Kansas City Preventive Patrol Experiment discovered that altering the amount of police patrol had no bearing on crime or how the general people perceived crime and did not lessen their fear of crime. In actuality, there had been no alteration to police patrols at all.
