Reference ballistic imaging database performance

Ballistic imaging databases allow law enforcement to link recovered cartridge cases to other crime scenes and to firearms. The success of these databases has led many to propose that all firearms in circulation be entered into a reference ballistic image database (RBID). To assess the performance of an RBID, we fired 4200 cartridge cases from 600 9 mm Para Sig Sauer model P226 series pistols. Each pistol fired two Remington cartridges, one of which was imaged in the RBID, and five additional cartridges, consisting of Federal, Speer, Winchester, Wolf, and CCI brands. Randomly selected samples from the second series of Remington cartridge cases and from the five additional brands were then correlated against the RBID. Of the 32 cartridges of the same make correlated against the RBID, 72% ranked in the top 10 positions. Likewise, of the 160 cartridges of the five different brands correlated against the database, 21% ranked in the top 10 positions. Generally, the ranking position increased as the size of the RBID increased. We obtained similar results when we expanded the RBID to include firearms with the same class characteristics for breech face marks, firing pin impressions, and extractor marks. The results of our six queries against the RBID indicate that a reference ballistics image database of new guns is currently fraught with too many difficulties to be an effective and efficient law enforcement tool.     

The International Criminal Tribunal for the Former Yugoslavia: Judgements in 2005

The year of 2005 was a productive one for the InternationalCriminal Tribunal for the Former Yugoslavia (ICTY), which rendereda total of ten judgements. The present article, concentratingon the key facts of the case and on novel development in internationalcriminal and humanitarian law, reviews—in chronologicalorder—the judgements of the ICTY Trial Chambers and ofthe Appeals Chamber.     

ALTERNATIVE ARRANGEMENTS FOR COST EFFECTIVE POLLUTION ABATEMENT: THE NEED FOR IMPLEMENTATION ANALYSIS

After examining policies and proposals designed to achieve cost-effective pollution abatement, the authors argue that design of economically elegant solutions to pollution control problems needs implementation analysis if the policies are to be successfully carried out. They review some institutional obstacles to implementation and conclude that these impediments should not prevent adoption.     

Swiss taxation of trusts currently and in the future

At the International Trust & Tax Planning Summit Conference,held from 30 October to 1 November 2006 in Coral Gables, Florida,Frédéric Vuilleumier considered the Swiss taxregime in a paper entitled ‘Inbound Guide: What ShouldYou Do When Assumptions Change?’ In this article, theSwiss direct tax system was discussed and the distinction madebetween federal and cantonal taxation, tax residence in Switzerlandand the question of jurisdiction under Swiss private internationallaw and the application of Swiss civil law where Swiss courtshave jurisdiction and the applicable law in matrimonial matters.The article is part of that paper and concentrates on the taxtreatment of trusts in Switzerland, the current position andthe impact of the draft circular to accommodate the then expectedaccession of Switzerland to the Hague Convention.     

Quantitative Differentiation of Bloodstain Patterns Resulting from Gunshot and Blunt Force Impacts

Bloodstain pattern analysis (BPA) provides significant evidentiary value in crime scene interpretation and reconstruction. In this work, we develop a quantitative methodology using digital image analysis techniques to differentiate impact bloodstain patterns. The bloodstain patterns were digitally imaged and analyzed using image analysis algorithms. Our analysis of 72 unique bloodstain patterns, comprising more than 490,000 individual droplet stains, indicates that the mean drop size in a gunshot spatter pattern is at most 30% smaller than the mean drop stain size in blunt instrument patterns. In contrast, we demonstrate that the spatial distribution of the droplet stains—their density as a function of position in the pattern—significantly differs between gunshot and blunt instrument patterns, with densities as much as 400% larger for gunshot impacts. Thus, quantitative metrics involving the spatial distribution of droplet stains within a bloodstain pattern can be useful for objective differentiation between blunt instrument and gunshot bloodstain patterns.     

Suicide by self-removal of a pacemaker

A 70-year-old man extracted his own pacemaker and subclavian port used for delivery of chemotherapy, both implanted 2 weeks earlier. The patient died of septicemia within 6 days. This fatal outcome illustrates the risks of complications associated with severe psychiatric disorders after implantation of prosthetic devices.     

Tax-exempt bonds and sponsored research

"Sponsored research," wherein a business corporation or the government pays a portion of the cost of research activities carried out by a university or hospital, is increasingly important both for state institutions and for Section 510(c)(3) organizations. Sponsored research arrangements that are not properly structured can jeopardize the status of tax-exempt bonds issued to finance the facility at which the sponsored research occurs. While these rules have been difficult to apply in practice, properly structured agreements can provide funding for research without undue risk. This Article discusses the multiple pieces of guidance put forth by the Internal Revenue Service to clarify the many issues and tiers of analysis necessary to ensure a properly-structured sponsored research agreement.
