The contribution of forensic science to crime analysis and investigation: forensic intelligence

The debate in forensic science concentrates on issues such as standardisation, accreditation and de-contextualisation, in a legal and economical context, in order to ensure the scientific objectivity and efficiency that must guide the process of collecting, analysing, interpreting and reporting forensic evidence. At the same time, it is recognised that forensic case data is still poorly integrated into the investigation and the crime analysis process, despite evidence of its great potential in various situations and studies. A change of attitude is needed in order to accept an extended role for forensic science that goes beyond the production of evidence for the court. To stimulate and guide this development, a long-term intensive modelling activity of the investigative and crime analysis process that crosses the boundaries of different disciplines has been initiated. A framework that fully integrates forensic case data shows through examples the capital accumulated that may be put to use systematically.     

The Evidentiary Introduction of Psychopathy Checklist-Revised Assessed Psychopathy in U.S. Courts: Extent and Appropriateness*

We examine the application of Psychopathy Checklist Revised (PCL-R) assessed psychopathy in U.S. courts from the time of the introduction of the PCL-R in 1991, through the end of 2004, and consider the PCL-R in light of relevant evidentiary standards and the empirical support for the construct of psychopathy. Our review of the Westlaw legal database indicates that the evidentiary introduction of PCL-R assessed psychopathy extends across state and federal jurisdictions, and has increased considerably in recent years. We identify nine contexts in which PCL-R evidence has been introduced and examine the appropriateness of such introduction. In most contexts the PCL-R was considered with regard to the prediction of violence in the community, and in such context the introduction of PCL-R scores appears appropriate, at least with regard to European American male offenders. However, PCL-R assessments may not meet relevant evidentiary standards with regard to the prediction of institutional violence and violence among females, adolescents and ethnic minorities.     

Risk assessment in offenders with mental disorders: relative efficacy of personal demographic, criminal history, and clinical variables

Following the meta-analysis by Bonta, Law, and Hanson, (1998) this study examined the ability of personal demographic, criminal history, and clinical variables to predict reoffending in offenders in the United Kingdom who had mental disorders. The efficacy of each variable in predicting rate of general reoffending and violent reoffending was investigated. Age on admission, number of days hospitalized, and number of previous offenses were the most effective variables in predicting re-offending, with number of previous offenses being the strongest predictor. Clinical diagnosis was not predictive of reoffending when the variance attributable to these other predictors was controlled for. None of the variables were able to discriminate between general offenders and violent offenders indicating that the same variables predict both types of reoffending. The results showed that reconviction in offenders with mental disorders can be predicted using the same criminogenic variables that are predictive in offenders without mental disorders.     

Population data for the AMPFlSTR Profiler plus STR loci from residents of the Australian Capital Territory (ACT)

Profiler Plus-Resident donors (N=620) from the Australian Capital Territory (ACT). Although the ethnicity of the donors was not recorded the population of the ACT is largely homogeneous, with over 96% of respondents declaring their ancestry as Caucasian in the 2002 National Census.     

Arbeiterbewegung von rechts? Motive und Grenzen einer imaginären Revolte

The article examines populist and völkisch orientations of unionized workers, some of them active members of workers’ councils. It empirically shows how, in respondents’ everyday consciousness, protest motifs are intermingled with an ethnicized view of the social question. Völkisch populism can be interpreted as a Polanyi-type movement that is motivated by problems generated by post-growth capitalism, presenting itself as a venture to give back power to the people. Its revolt remains an imaginary one, though, for, ultimately in accordance with existing power relations, it aims at reconstructing an irretrievable past. Our empirical results keep a distance from monocausal explanations, though call to mind issues of class that have long been neglected. As workers perceive the current distribution of wealth as unjust, yet don’t believe in any possibility for change, they are spontaneously inclined to redefine existing top-down conflicts into inclusion-exclusion types. Professional right-wing populists take up and aggravate this tendency of exclusive solidarity and thereby pose a serious challenge for the unions as well as for democratic civil societies.     

Pollen on grass clippings: putting the suspect at the scene of the crime.

In a case of alleged sexual assault, the pollen content of samples of grass clippings and soil from the suspect's clothing and shoes was compared to that of a sample of grass clippings from the alleged crime scene (a grassy area) to determine whether or not the suspect had been at the scene. The clothing and shoe samples showed a very strong correlation with each other and with the sample from the alleged crime scene in the combination of the different types of pollen present, very strongly supporting the contention that the suspect had been at the scene.
