An evaluation of matching unknown writing inks with the United States International Ink Library

Utilizing a database of standards for forensic casework is a valuable resource. Undoubtedly, as more standards (and corresponding information about the specimens) are collected, there is a greater certainty of identification when a questioned and a known item cannot be distinguished after a series of analyses. The United States Secret Service and the Internal Revenue Service National Forensic Laboratory jointly maintain the largest known forensic collection of writing inks in the world, which is comprised of over 8500 ink standards collected worldwide, dating back to the 1920s. This study was conducted to evaluate the reliability of matching arbitrarily purchased pens with known inks from a database. One hundred pens were randomly obtained from a variety of sources and their respective ink compositions were compared with standards. Eighty-five of the inks were determined to be suitable for comparison utilizing optical examinations and thin-layer chromatography. Three of the inks did not match any of the specimens on record; one of these inks was similar to an ink from an identical brand of pen that was in the database, but had a modified formulation.     

Transnational Legal Process and State Change

This article applies a sociolegal approach to the study of transnational legal processes and their effects within countries. First, we clarify the concepts of transnational law, transnational legal process, and transnational legal order. Second, we provide a typology of five dimensions of state change that we can assess empirically. Third, we explain the factors that determine the variable effects of transnational legal processes and organize these factors into three clusters. Fourth, we introduce four empirical studies of transnational legal processes' differential effects in five regulatory areas in Asia, Africa, and South America that illustrate these points. Together, they provide a guide of how to study the interaction of transnational and national legal processes, and the extent and limits of transnational legal processes' effects.     

Alessandro Orsini. Anatomy of the Red Brigades: The Religious Mind-Set of Modern Terrorists

ABSTRACT

Those who study terrorism are familiar with the claim that suicide attacks are the most lethal form of terrorism today. Suicide attacks kill more people on average than non-suicide attacks, thereby justifying why terrorist organizations use this costly method of attack and explaining in part why suicide tactics have proliferated. However, extant empirical support for this claim is largely insufficient, focusing only on macro-level analysis of lethality data. Using data from the Global Terrorism Database, this study examines variation in lethality among suicide and non-suicide attacks based on geographic location, attack type, and target/victim type. It also introduces a new metric—the lethality ratio—to measure costs and benefits of attacks in terms of lives lost. It finds that, although suicide tactics are generally more lethal than non-suicide tactics, they also come at greater costs to the organization. This analysis also finds behavior that is inconsistent with the premise that terrorist groups are focused on maximizing lethality while reducing costs in all cases; that despite certain advantages, suicide attacks may remain a suboptimal tactic from the perspective of the terrorist group; and that additional criteria may help explain why suicide tactics are used.     

On Finding for Defendants Who Plead Insanity: The Crucial Impact of Dispositional Instructions and Opportunity to Deliberate

One hundred twenty participants functioned as mock-jurors and as members of deliberating juries in an experiment designed to assess the impact of dispositional instruction on verdicts rendered in an insanity trial. Consistent with prior research (K. E. & J. R. Ogloff, 1995), dispositional instruction had no effect on the verdict preferences of individual jurors prior to deliberating. Yet, as expected, the instruction manipulation had a major impact on postdeliberative decisions (i.e., group verdicts; individual juror verdict preferences). Content analyses of jury deliberations revealed that postdeliberative shifts toward harsh verdicts in uninstructed juries and toward lenient verdicts in instructed juries were mediated by the impact of the Instruction manipulation on the content of jury deliberations: uninstructed juries feared that an acquitted-insane defendant would be freed to act again, whereas instructed juries recognized that finding for an insane defendant implied his retention and treatment. Implications of these results for both legal policy and the conduct of mock-trial research are discussed.
