Predictive policing, mass data-analysis for crime prediction
Abstract. Predictive policing is the application of data-analysis on crime data to predict criminal activity. This short paper presents an overview of the prediction-led policing process.
1. Introduction. The effectiveness of the police is limited to their available resources. Smart and anticipatory policing is necessary to combat crime better and to use limited resources more efficiently. Predicting future crime has recently gained notable currency in law enforcement. By finding patterns in data on past crimes the police can identify potential future criminality. This short paper surveys the different steps taken in this predictive-led policing.
2. Preliminaries. We assume familiarity with the basic concepts of regression analysis [1], and …show more content…

Most police departments collect crime data. To make predictions however, you also need information on the environment these crimes took place in. The various data sources need to be combined by analysts. Something to keep in mind is that predictions heavily depend on the amount and quality of the data. If it lacks one of these, the predictions become unreliable.
Once the data is collected, it has to be analysed by analytical techniques; the second step. Various techniques like regression and data-mining can be used on the data to find crime patterns. The resulting patterns can then be used to inform a method that identifies hot spots. As important it is to have good data, it is also important to have good analytical techniques. Poor quality techniques will result in poor predictions.
The third step is the intervention of the police based on the predictions. The type of intervention vary according to the problem. If there is an increased risk of local crimes, the police can relocate more resources to that area. Predictive policing also allows the police to identify the sources of crime and combat them

Comparison Of Integrative And Geographic Profiling

As constantly repeated in many interdisciplinary sciences, most prone in criminology, a victim is likely to be familiar with their offender or had encountered their offender at a time prior to the attack (Rossmo, 1998). This theory is a psychological approach to examine criminality, by analyzing the offender in connection to the victim and the crime. A more concrete approach is the use of environmental criminology, the analysis of the crime in relation to the offender; how the social environment manipulates the behavior of the offender. An integrative approach complementing the two investigative strategies to resolving crime is geographic profiling. Geographic Profiling is an investigative strategy that examines the influence of the physical

Crime Mapping Advantages And Disadvantages

Police (Disadvantages) • Crime mapping is open source information which anyone can access online, adversaries included. Crime mapping will aid adversaries in planning and earmarking criminal activities based on the information provided online. Adversaries can clearly see where police forces are most active and which locations are targeted more often. Adversaries can therefore target the same locations due to poor base line security measures from local police, residents and companies, or target locations where police activity is minimal. Crime mapping is man power intensive and requires additional support updating the system with real time information.
