The criminal profiling illusion:what's behind the smoke and mirrors?

There is a belief that criminal profilers can predict a criminal's characteristics from crime scene evidence. In this article, the authors argue that this belief may be an illusion and explain how people may have been misled into believing that criminal profiling (CP) works despite no sound theoretical grounding and no strong empirical support for this possibility. Potentially responsible for this illusory belief is the information that people acquire about CP, which is heavily influenced by anecdotes, repetition of the message that profiling works, the expert profiler label, and a disproportionate emphasis on correct predictions. Also potentially responsible are aspects of information processing such as reasoning errors, creating meaning out of ambiguous information, imitating good ideas, and inferring fact from fiction. The authors conclude that CP should not be used as an investigative tool because it lacks scientific support

Reconstructing and sequencing behaviours in multiple perpetrator rape

Much of the existing knowledge base of multiple perpetrator rape (MPR) comes from studies undertaken more than 20 years ago, and thus fails to integrate contemporary perspectives on sexual violence. The current study used Grounded Theory methodology to construct a holistic model of MPR from 15 victim accounts. The model of multiple perpetrator rape (MMPR) included both the actions of the perpetrators and the reactions of the victim in a temporal sequence of 13 categories, 9 of which had sub-categories that allowed for individual differences. Broad themes of MPR were then explored using a total of 101 cases. Each case was coded in the 9 sub-categories where individual differences were allowed from the model. An associative analysis of these sub-categories was then performed using Smallest Space Analysis. Two dominant themes were displayed. The Manipulate theme included two perpetrators who offended sequentially and socialised with the victim. The Force theme did not involve any social interaction, as the force and teamwork of the group enabled the victim to be physically overpowered

A typology of multiple perpetrator rape

Some consistency in existing typologies of rape has been found, which have extended from lone to multiple perpetrator offenses. The current study sought to explore the facets of multiple-perpetrator rape (MPR) in a sample representative of one geographical area. Seventy-five victim statements of MPR reported to an urban police force in the United Kingdom were classified into a qualitative model denoting offender actions in MPR. Four types from pathways through the model were produced: violence, criminality, intimacy, and sexuality. Analysis of the crime scene variables provided additional evidence of the four types. Finally, the associations between the four types and offense characteristics, such as victim and perpetrator age, were explored. Implications of these findings for the prevention and investigation of MPR are discussed along with suggestions for future research directions
