The advent of democracy in South Africa brought hope for freedom and prosperity for millions of South Africans. The country also experienced an increase in violent crime during those early years of democracy. In order to deal with the threat of crime the government had to develop policing strategies which would eradicate crime and fear of crime. As a young democracy South Africa had to look for policing models which has successfully decreased the high crime rate in developed countries. Fortunately the western democracies like the United Kingdom, United States of America and Australia had some of these answers. Firstly it was community policing, then sector policing, and finally intelligence led policing. This research focuses on the intelligence led policing model by discussing its building blocks in chronological order as follows. Firstly is the historical background of intelligence; Secondly, is information collection; Thirdly is crime analysis; and Fourthly is the Intelligence-cycle, with specific focus on the implementation process in England in the United Kingdom; New Jersey in the United States of America, South Australia State in Australia; and in the Republic of South Africa. A questionnaire was used to collect data on the implementation of intelligence led policing by the South African Police Service / Police Practice / D. Litt. et Phil. (Police Science)

The problem that was identified is that physical surveillance is not generally used by general detectives in the South African Police Service as a technique during their investigations. According to the researcher’s experience, this can be due to lack of understanding or experience or may stem from ignorance. A lack of training on the use of physical surveillance as a method to obtain information for the investigation process was also identified as a problem. This study therefore investigated the role and use of physical surveillance within the forensic investigation process. The focus of the research was on basic static (stationary), foot and vehicle surveillance as these types of surveillance are usually conducted in conjunction with each other. An empirical research design was used to conduct the research. A qualitative research approach enabled the researcher to obtain first-hand information from interviews with general detectives. Information was also obtained from a thorough literature study and from the researcher’s own experience on the topic. To conduct effective investigation, it is important for investigators to be familiar with the concept of physical surveillance, its elements, its influence and its values. A physical surveillance operation is a forensic tool used to gather evidence, to recover stolen property, and to identify and arrest the perpetrator. The use of physical surveillance during investigations serves the purpose of gathering evidence and information that can be used as intelligence. Successful forensic investigation requires skill and places extraordinary demands on detectives to utilise all available methods and techniques. The recognition of the use of physical surveillance as a method of evidence gathering is of outmost importance. The research has revealed that general detectives do not acknowledge the importance of physical surveillance as a method to obtain information for the investigation process. It is of vital importance that all detectives be properly trained with the necessary knowledge and skills to make use of this valuable investigative tool. / Police Practice / M. Tech.

Indiana University-Purdue University Indianapolis (IUPUI) / Law enforcement agencies across the U.S. use maps of crime to inform their practice and make efforts to reduce crime. Hotspot maps using historic crime data can show practitioners concentrated areas of criminal offenses and the types of offenses that have occurred; however, not all of these hotspot crime mapping techniques produce the same results. This study compares three hotspot crime mapping techniques and four crime types using the Predictive Accuracy Index (PAI) to measure the predictive accuracy of these mapping techniques in Marion County, Indiana. Results show that the grid hotspot mapping technique and crimes of robbery are most predictive. Understanding the most effective crime mapping technique will allow law enforcement to better predict and therefore prevent crimes.

The relationship between mass-transit and the concentration of burglary and robbery crimes is inconsistent within the available literature in environmental criminology. A number of studies have provided evidence of crime concentration at and near mass transit locations where paths intersect, referred to as a node. These empirical studies bring in environmental criminology theory with the idea that crime is clustered, and the pattern of the concentrations is substantially influenced by how and why people travel and move in a city. It is suggested that public transit allows for a large proportion of the population to move around the community along a restricted number of destinations and paths; therefore, this concentration of population frames opportunities, and increases overall concentrations of crime. Establishments and environments surrounding transit nodes may act as crime generators or attractors, as a high influx of people are drawn to the area via nearby transit services. More recent literature has identified contrasting results, finding that crime does not concentrate near mass transit areas. In some cases, transit facilities appear to act as protective nodes, with lower counts of crime occurring in and around these locales. Given the conflicting results of existing research about crime at and near transit nodes, this study advances work in environmental criminology by analyzing the concentration of burglary and robbery events in Portland, Oregon. Recognizing that crime concentrations may vary depending on the level of analysis, this study explores crime concentrations at multiple levels of analysis. At the macro-level, this study examines burglaries and robberies across Portland as a whole to determine whether these events concentrate around mass transit nodes, when compared to other areas of the city. The meso-level examines within the broad category of mass transit, to explore whether burglary and robbery events cluster differently around different types of mass transit. Finally, the micro scale investigates the five highest-crime transit nodes to explore how burglary and robbery events concentrate in close proximity to these important locations. This study finds that while crime concentrates at higher levels surrounding mass transit nodes within Portland, the patterns of this concentration changes as the spatial level of analysis changes.

La mesure traditionnelle de la criminalité (taux pour 100 000 habitants) pose problème dans l'analyse des variations de la criminalité dans le temps ou l'espace. Le problème est dû au fait que le taux de criminalité est essentiellement déterminé par des infractions moins graves et très fréquentes. La présente étude a permis de tester l’utilité du nouvel outil développé par Statistique Canada qui procure un index de « gravité de la criminalité » dans lequel chaque crime est pondéré par son score de gravité (basé sur les décisions sentencielles moyennes au Canada de 2002 à 2007 pour chaque forme de crime). Appliquées aux statistiques officielles du Québec de 1977 à 2008, nos analyses montrent que l’indice de gravité s’avère une mesure utile pour dresser un portrait plus juste des tendances des crimes violents d’une année à l’autre. Plus exactement, l’indice de gravité montre que le taux de crimes violents est demeuré stable de 1977 à 1992 contrairement à l'image fournie par le taux traditionnel qui montre plutôt une montée fulgurante durant cette période. L’indice de gravité peut également être utile à l’égard des crimes violents pour comparer plus adéquatement les territoires entre eux afin d’établir ceux qui présentent une criminalité plus grave. Cependant, à l’égard de la criminalité globale et des crimes sans violence, l’indice de gravité n’est d’aucune utilité et présente la même lecture de la criminalité que la mesure traditionnelle. Cela s’explique par le fait que ce sont toujours les mêmes infractions (les vols, les méfaits et les introductions par effraction) qui contribuent majoritairement à chacune des deux mesures de la criminalité. / The traditional measure of the criminality (rate for 100 000 inhabitants) raises problem in the analysis of the variations of the criminality in time or space. The problem is due to the fact that the rate of criminality is essentially determined by less serious and very frequent crimes. The present study allowed testing the utility of a new tool developed by Statistics Canada which gets an index of "severity of criminality" in which every crime is weighted by its score of severity (based on the sentencielles decisions average in Canada from 2002 till 2007 for every kind of crime. Applied to the official statistics of Quebec from 1977 till 2008, our analyses show that the indication of gravity turns out to be a useful measure to draw up a more realistic portrait of the trends of violent crimes from one year to the next. More precisely, the crime seriousness index shows that the rate of violent crimes remained stable from 1977 till 1992, on contradiction to what is shown by traditional rate which rather demonstrates a huge rise during this period. Crime seriousness index can also be used towards violent crimes, in order to compare more adequately territories, to establish those who show more serious crimes. However, among global criminality and crimes without violence, the indication of gravity is of no utility and presents the same reading of the criminality as traditional measures. It explains that it is always the same crimes (thefts, mischief and breaking and entering) that contribute mainly to each of both measures of the criminality.
