The field of forensic science is increasingly based on biomolecular data and many European countries are establishing forensic databases to store DNA profiles of crime scenes of known offenders and apply DNA testing. The field is boosted by statistical and technological advances such as DNA microarray sequencing, TFT biosensors, machine learning algorithms, in particular Bayesian networks, whic...

Policy initiatives based on that evidence have been shown to be effective. A recently published study conducted by a leading policy organization presents new evidence and makes specific recommendations for action by ...

This paper extends the optimal law enforcement literature to organized crime. We model the criminal organization as a vertical structure where the principal extracts some rents from the agents through extortion. Depending on the principal's information set, threats may or may not be credible. As long as threats are credible, the principal is able to fully extract rents. In that case, the result...

There is a broad consensus that the Internet has greatly expanded possibilities for traditional transit crimes such as wildlife trafficking. However, the extent to which the Internet is exploited by criminals to carry out these types of activities and the way in which it has changed how these crimes are carried out remains under-investigated. Based on interviews and investigative cases, this pa...

Computer crime hackers have been identified as a primary threat to computer systems, users, and organizations. Much extant research on hackers is conducted from a technical perspective and at an individual level of analysis. This research empirically examines the social organization of a hacker community by analyzing one network called Shadowcrew. The social network structure of this infamous h...

Since the seminal works of Wilson and Kelling [1] in 1982, the “broken windows theory” seems to have been widely accepted among the criminologists and, in fact, empirical findings actually point out that criminals tend to return to previously visited locations. Crime has always been part of the urban society’s agenda and has also attracted the attention of scholars from social sciences ever sin...
