Development of a methodology for the standardisation and improvement of ‘Smartphone’ photography of patterned bruises and other cutaneous injuries

Human bite-mark analyses can play a prominent role in forensic case investigations, including those involving sexual assault. High-quality photographs routinely secure a link between a bite-mark and an individual's dentition. Access to around the clock forensic photography, however, is often limited, resulting in delay and/or missed opportunities to record valuable evidence. The emergence of Smartphone high-quality photographic technology now provides a previously unimagined opportunity to gather timely forensic photographic evidence. Problems can arise, however, due to the relatively poor quality of the photographs, as a result of many of those taking photographs having received little or no forensic photography training. This study compares unassisted photography with assisted photography, by a specifically developed camera application (App), to provide a standardised method for taking forensic photographs. An App, written in Java, was hosted on the Google Android Operating System, on a Samsung Galaxy SII Smartphone. Twenty-four volunteers participated in a study to photograph a pseudo bite-mark using three methods, (1) unassisted (as a control), (2) assisted by an ABFO No.2 right-angled photographic reference scale and (3) assisted by the App. The App, method (3), was shown to consistently outperform methods (1) and (2), demonstrating greater standardisation and precision (p < 0.001). Analysis of the data showed the extent to which acquiring an accurate photograph depends on the image being orthogonal to the camera. It appears likely that the relatively inaccurate photographs acquired by methods (1) and (2), were as a result of deviation from the plane, orthogonal to the bite-mark. Therefore, the App was successful in ensuring that the camera was both orthogonal and at an appropriate distance, relative to the bite-mark. Thus, the App enhanced the abilities of non-experts to acquire more accurate photographs and created the potential to significantly improve the quality of forensic photographs.     

Land Reform in El Salvador and the Chapultepec Peace Accord

The focus of this article is on the land transfer programme (PTT) carried out in El Salvador over the past decade as a result of the 1992 Chapultepec Peace Accord. Building on the agrarian reforms of the 1980s, the PTT beneficiaries were smallholders created by the state and drawn from ex-combatants on both sides (the FMLN, the military) in the war. Among the issues considered are the forms of tenure that resulted, and the agrarian debt incurred. Also examined is the socio-economic profile of the PTT beneficiaries, together with their assessment of the positive/negative impact on their lives of the reform programme. Finally, the achievements and failures of the PTT are evaluated in terms of the wider national/international context, and the resulting contradiction between the objectives of the agrarian reform and the determinants of global markets.     

Measuring criminal justice technology outputs: The case of Title III wiretap productivity, 1987-2005

This analysis considers outputs produced by Title III electronic wiretaps. Based on 1987-2005 data, wiretap productivity is assessed by examining the number of wiretaps, places wiretaps are installed, numbers of people whose communications are intercepted, the number of intercepted communications, the number of communications labeled incriminating, the arrests and convictions linked to wiretaps, and the relationships among arrests and convictions. Wiretapping is focused mostly on narcotics violations. The numbers of people, interceptions, and incriminating interceptions increased. One-fifth of intercepted communications were classified as incriminating. Incriminating information is linked to arrests and convictions that unfold over time. The more people intercepted, the more arrests result, but convictions decline over time. Arrests are driven by the number of intercepted persons. Convictions are driven by the number of incriminating interceptions. Two simultaneous but opposing operations were in place by 2005: big increases in the number of intercepted communications in 2003 through 2005; and by 2005, overall declines in the measured productivity of wiretaps.
