Recent reform of intelligence in the UK: Democratization or risk management?

The recent flurry of intelligence legislation in the UK can be taken to mean that Britain has democratized its intelligence services in line with other western democracies. However, this argument is rejected. The changing role of intelligence, particularly in the area of ‘serious and organized crime’, altered the environment in which intelligence services operate and meant that they lost their monopoly of control over information. It is more a process of risk management than democratization. The Intelligence Services Act 1994 and the role of the new oversight body, the Parliamentary Intelligence and Security Committee, are also assessed.     

A textile fibre survey as an aid to the interpretation of fibre evidence in the Sydney region.

Frequency figures of the fibre population on textile cinema seats were measured in Sydney, Australia, in winter. Sixteen seats were analysed from a very popular cinema complex, with 3025 fibres classified according to colour, generic class and fluorescence properties (100 grey-black cotton fibres only). The recovered fibres were mostly natural fibres (84%) with cotton the most common generic type (70%). On the contrary, man made fibres were relatively rare (15%) with rayon constituting the majority of these (51%). The most common colour/generic class combinations were grey-black cotton (33%) and blue cotton (30%) accounting for 63% of the total population. All other frequencies were below 5%, most below 1% using only the two properties of colour and generic class. Fluorescence properties were found to be very discriminating as far as grey-black cotton fibres were concerned. These features are considered and discussed and in particular, to emphasise the significance of fibres as evidence of contact.     

Developmental validation of a Cannabis sativa STR multiplex system for forensic analysis

A developmental validation study based on recommendations of the Scientific Working Group on DNA Analysis Methods (SWGDAM) was conducted on a multiplex system of 10 Cannabis sativa short tandem repeat loci. Amplification of the loci in four multiplex reactions was tested across DNA from dried root, stem, and leaf sources, and DNA from fresh, frozen, and dried leaf tissue with a template DNA range of 10.0-0.01 ng. The loci were amplified and scored consistently for all DNA sources when DNA template was in the range of 10.0-1.0 ng. Some allelic dropout and PCR failure occurred in reactions with lower template DNA amounts. Overall, amplification was best using 10.0 ng of template DNA from dried leaf tissue indicating that this is the optimal source material. Cross species amplification was observed in Humulus lupulus for three loci but there was no allelic overlap. This is the first study following SWGDAM validation guidelines to validate short tandem repeat markers for forensic use in plants.     

Extending the Confusion About Bayes

In R v T [2010] EWCA Crim 2439, [2011] 1 Cr App Rep 85, the Court of Appeal indicated that ‘mathematical formulae’, such as likelihood ratios, should not be used by forensic scientists to analyse data where firm statistical evidence did not exist. Unfortunately, when considering the forensic scientist's evidence, the judgment consistently commits a basic logical error, the ‘transposition of the conditional’ which indicates that the Bayesian argument has not been understood and extends the confusion surrounding it. The judgment also fails to distinguish between the validity of the relationships in a formula and the precision of the data. We explain why the Bayesian method is the correct logical method for analysing forensic scientific evidence, how it works and why ‘mathematical formulae’ can be useful even where firm statistical data is lacking.     

The police education qualification framework: a professional agenda or building professionals?

ABSTRACT

Given the growing complexity in British policing, the College of Policing are implementing a Police Education Qualification Framework through a professionalization agenda. This aims to standardise entry to the police and allow serving officers to gain accreditation for their previous training and experience. Part of this process involves the development of a national police curriculum for higher education institutions to deliver to new recruits. Different definitions of what constitutes professionalism can impact on officers’ interpretations of this concept and how they subsequently engage with the proposed reforms. This paper, which is based on in depth qualitative interviews with serving officers who have undertaken an academic qualification in policing, suggests that the relationship between police education and the development of professionalism is complex. Officers need to be trusted and encouraged to use their learning in a way that develops their own personal sense of professionalism. However, this paper will argue that current perceptions amongst officers are sceptical of the wider agenda and brings into question the development of a standardised curriculum which may ultimately be viewed as further governance over officer behaviour.     

Family violence and depressive symptomatology among incarcerated women

This study examines the potential association between witnessing parental violence as a child and later adult depressive symptomatology within a population that has received limited attention in the scientific literature, namely, incarcerated women. The Conflict Tactics Scale and the Center for Epidemiological Studies Depression Scale were administered to 60 women incarcerated in a maximum security prison in North Carolina. A majority of the women reported that they had witnessed verbally aggressive or physically violent interactions among the adult members in their families. Seventy percent of these women suffered from clinically relevant levels of depressive symptomatology. Stepwise multiple linear regression analysis revealed that increasing levels of reasoning conflict resolution strategies used in the women's families of origin were associated with decreasing levels of depressive symptomatology of the women, whereas increasing levels of physically violent conflict resolution strategies were associated with increasing levels of depressive symptomatology.     

District Judges and Possession Proceedings

In this article, we draw on data obtained in interviews with District Judges about the factors which they say influence the exercise of their discretion in possession proceedings. Analysing the data set enabled us to create three ideal types of judicial decision—making which we have labelled 'liberal', 'patrician', and formalist'. We discuss the differences between each ideal type across five different variables: the District Judge role; approach; view of occupiers; the problem; behaviour of occupiers. Our data demonstrate a set of reasons to explain different approaches and outcomes between different District Judges (as well as the perhaps unlikely identification of a 'maverick' or 'idiosyncratic' style of judging). We conclude by suggesting on the basis of our data that, despite calls to structure or remove the discretion from District Judges, any such changes are unlikely to have much effect.     

Hemolyzed blood and serum levels of delta 9-THC: effects on the performance of roadside sobriety tests

A pilot study was conducted to ascertain the range of induced hemolyzed blood/serum delta 9-tetrahydrocannabinol (delta 9-THC) concentrations in 58 human subjects. Subjects were tested within 5 min of smoking a delta 9-THC cigarette and then at half-hour intervals to 150 min. The subjects initially demonstrated a broad range of delta 9-THC hemolyzed blood levels, which settled within an hour to levels comparable to those measured in California drivers who had been stopped for impaired driving, arrested, and tested for delta 9-THC. Serum levels, when correlated with performance or roadside sobriety tests, demonstrated a broad range (5 to 183 ng/mL) of delta 9-THC levels and an "adaptation" effect in the subjects' perception of their own impairment. Although this preliminary study was not a double-blind placebo experiment, the overall performance of human subjects demonstrated the "adaptation" effect, which may be a significant factor in making judgments while performing such complex tasks as driving. Also, the effects of the drug extended beyond the period of elevated delta 9-THC blood levels, perhaps because of THC metabolites that may contribute to impairment or the persistence of THC in the central nervous system. This pilot study will lay the groundwork for a program designed to determine the epidemiology and behavior correlates of marijuana use in motorists.
