A crime is an act which is against the laws of a country or region. The technique which is used to find areas on a map which have high crime intensity is known as crime hotspot prediction. The technique uses the crime data which includes the area with crime rate and predict the future location with high crime intensity. The motivation of crime hotspot prediction is to raise people’s awareness r...

Crimes will somehow influence organizations and institutions when occurred frequently in a society. Thus, it seems necessary to study reasons, factors and relations between occurrence of different crimes and finding the most appropriate ways to control and avoid more crimes. The main objective of this paper is to classify clustered crimes based on occurrence frequency during different years. Da...

Brain-activity markers of guilty knowledge have been promoted as accurate and reliable measures for establishing criminal culpability. Tests based on these markers interpret the presence or absence of memory-related neural activity as diagnostic of whether or not incriminating information is stored in a suspect's brain. This conclusion critically relies on the untested assumption that reminders...

L aw enforcement officials have consistently ranked the development of remote weapons detection technology as a top priority. Thus when President Clinton read an article by the eminent public policy analyst James Q. Wilson on “What To Do About Crime” in Commentary magazine, he marked two key passages for review and action. Wilson pointed out that although firearms play a key role in rising viol...

Nowadays, facial expression detection and expression recognition has become one of the most important topics in research field. Facial expressions may be used to identify criminals. In today’s scenario, the crime rate is increasing day-by-day and criminals are set free due to lack of evidence. Investigators often express confidence in their potential to spot a lie. But identifying a criminal wh...

This paper analyzed the spatial patterns of four types of crime (assault, robbery, autotheft, and burglary) and their relationship with neighbourhood characteristics in the City of Omaha, Nebraska by using geographic information systems procedures and ordinary least square regression methods. Location quotients of crime and crime density were employed as two alternative measures of crime rates....

Throughout the criminal justice system, prosecutors have wide discretion to exercise their authority in determining what crimes should be prosecuted. This discretion has historic support through both constitutional separation of powers doctrines and public policy. This discretion is based on a variety of factors, including the severity of the crime, the extent of the evidence, prosecutorial res...

The input value for the maximum spatial scan extent (K) of a prospective space-time scan statistical (PSTSS) technique is one important parameter that ensures accurate detection of the predictive hotspot of geographical point events. Currently, there is no general consensus on how to determine the optimal value of K that maximises the predictive accuracy, especially in crime hotspot prediction....

Since the 1980s, successive UK governments have sought to increase efficiency in, and effectiveness of, policing through what has been described as “cycles of reform” (Reiner, 2000, p. 204). The reforms typically involved exerting greater central control over regional police forces. Many of the early initiatives met with resistance from within the police and, as a result, were not fully impleme...

The solution of hydrogen peroxide is a critical ingredient of the Weber luminol application for blood detection at the crime scene. An ideal alternative to the unstable hydrogen peroxide is a solid compound which is easy to transport, stable and quick to solve in water at the crime scene. Carbamide peroxide (urea peroxide) is one of these solid hydrogen peroxide carriers which is easy to obtain...
