Under the microscope: legal challenges to fingerprints and DNA as methods of forensic identification1

Suspects in legal cases can be identified by an ever‐growing list of novel methods. The most common techniques currently used include latent print and DNA analysis. Although standard fingerprinting entered the courtroom over a century ago, the admissibility of fingerprint evidence has undergone a period of intense scrutiny in the USA in recent years. In contrast, most challenges to DNA analysis as a science came during its inception in the late 1980s and early 1990s. Current challenges to fingerprint evidence attempt to discredit the science behind the theory whereas challenges to DNA evidence often bring into question the competency of the analyst. In either case, the lessons learned in various court systems give guidance for those implementing the newer emerging biometric identification technologies such as facial recognition systems, retinal scans and the like. The first section of this article deals with fingerprint analysis and recent challenges to fingerprint admissibility in US courts. The second section discusses the evolution of DNA analysis and relevant cases. The final section gives recommendations for emerging biometric technologies to follow to satisfy the standards set forth by the courts.     

Natural Settings Trials — Improving the Introduction of Clinical Genetic Tests

Approaches to genetic testing differ in the research setting and the clinical setting. More data are needed to develop approaches that will best facilitate the use of new genetic tests in the clinical setting, especially settings where genetic testing has not been widely used, such as in primary care. Furthermore, data are needed to establish the clinical utility of new genetic tests in the general practice setting. Natural setting trials are proposed as a strategy to develop this information. While natural setting trials are clinical research studies and will expose participants to some degree of risk, the risks are different, and arguably less than the risks those same individuals would otherwise face if the test went directly into clinical practice. Ultimately, clinical practice and safety of new genetic tests can be improved by adding the evaluation provided by natural setting trials.     

Authoritarianism,religiosity and reactions to deviance

A modified F-Scale and a deviance-control scale were administered to a sample of 116 police science students and a random representative sample of 91 state university students. No overall relationship was found between respondents' preference to control deviance and their authoritarianism, nor did the F-Scale discriminate between the two groups. However, the police sample favored the control of deviance significantly more. Evidence of response bias to the F-Scale was also found. It was concluded that the source of the criminal sanction usually typified as moral indignation, was more a cognitively based evaluation than an emotionally based reaction.     

Reasons for refraining from criminal activity

In order to establish the relative importance of reasons for not engaging in illegal activities, respondents were administered a questionnaire containing a list of possible factors that could account for not committing crimes, and were then asked to rank them. Multidimensional scaling analyses revealed the underlying structure of these factors. Specifically, respondents tended to structure their reasons based on the formality/informality of a negative consequence and the relative seriousness of a sanction.     

LSD Use as a barrier to public safety employment: A review of the medical findings

Conclusions In a review of available literature on the topic of adverse effects of the use of hallucinogenics, the authors found some remarkable evidence. First, there is not evidence that these drugs are physically or emotionally addictive. In fact, users generally discontinue use because of the impact of altering states of consciousness. Few have the desire to experience these effects beyond satisfying their curiosity about the drugs. There seem to be some specific personality factors that predispose individuals to experiment with psychedelic drugs, and certainly, specific personality types are prone to be associated with negative side effects in both the short and long-term. In light of the considerable amount of research which supports the premise that LSD is not as dangerous as once assumed, perhaps restrictive hiring policies should be reviewed and reevaluated in the case of the one-time user. If an individual passes all testing, and personal history shows stability, disqualifying a candidate for prior LSD use does not appear to be supportable by research finding. Again, this report is not meant to diminish the negative effect of hallucinogens on a small portion of our society. The intent is to point out that the medical literature does not support the contention that one-time hallucinogen use carries with it any undesirable long-term consequences. The importance of considering an individual within the context of testing and background can not be minimized.     

Seen but not heard: Native people in four Canadian inner cities

This essay provides an overview of research on Native people in the inner core of four cities. This research was funded by the Aboriginal Justice Directorate, Department of Justice as part of the Aboriginal Justice Initiative. The objective of the research was to elicit information along a number of dimensions including: background, coming to the city, life in the city, experiences with the criminal justice system, and aspirations for the future. The information was used to compare east/west differences in Aboriginal incarceration levels, to explore urban and rural/reserve offences, and social stratification within the inner-city population. The findings revealed that social stratification exists in the inner-city Native population and that the more marginal the position, the greater the involvement with the criminal justice system. The findings also showed the relationship between childhood and adult experiences. East/west variation in Native incarceration levels can be explained by the findings that more people in the west belonged to the most marginal group in terms of education, employment, skills, and childhood disruption and violence. The findings argue for policy and program attention to be directed to those whose needs are greatest. When ‘broad brush’ solutions are applied, those with the most and least needs are treated equally. This essay is an overview of research contained in a three part volume,Seen but not Heard: Native people in the Inner City. Ottawa: Justice Canada.
