A central question in law and economics is whether, with limited resources, police activity should be narrowly focused and high force, or widely-dispersed but of moderate intensity. Critics of intense “hot spot” enforcement argue that this approach will only lead to crime shifting to other locations or other times. But if law breakers take time to learn that enforcement has begun, the police ma...

Criminal activities are unevenly distributed over space. The concept of hotspots is widely used to analyze the spatial characters of crimes. But existing methods usually identify hotspots based on an arbitrary user-defined threshold with respect to the number of a target crime without considering underlying controlling factors. In this study we introduce a new data mining model – Hotspots Optim...

In this work, we propose a method for three-dimensional (3D) reconstruction of wide crime scene, based on a Simultaneous Localization and Mapping (SLAM) approach. We used a Kinect V2 Time-of-Flight (TOF) RGB-D camera to provide colored dense point clouds at a 30 Hz frequency. This device is moved freely (6 degrees of freedom) during the scene exploration. The implemented SLAM solution aligns su...

One of the more popular approaches for the detection of crime hot spots is cluster analysis. Implemented in a wide variety of software packages, including CrimeStat, SPSS, SAS, and SPLUS, cluster analysis can be an effective method for determining areas exhibiting elevated concentrations of crime. However, it remains a particularly challenging task to detect hot spots using clustering technique...

Forensic botany is still an under-utilized resource in forensic casework, although it has been used on occasion. It is an area of specialty science that could include traditional botanical classification of species, DNA, or materials evidence (trace and transfer evidence), crime mapping or geo-sourcing, all dependent on the specific case application under consideration. Critical to the evaluati...

Stalking is one of the main types abusive behaviour facilitated by technology. The purpose current study was twofold: to identify challenges cyberstalking investigations and prosecutions in Australia determine how best investigate these offences. A qualitative analysis four years interviews, focus groups participant observations with police departments provides an overview investigative process...
