The Impact of the 1994 Federal Assault Weapon Ban on Gun Violence Outcomes: An Assessment of Multiple Outcome Measures and Some Lessons for Policy Evaluation

The Federal Violent Crime Control and Law Enforcement Act of 1994 bans a group of military-style semiautomatic firearms (i.e., assault weapons) and ammunition magazines capable of holding more than 10 rounds. Ban advocates argue that these weapons are particularly dangerous because they facilitate the rapid firing of high numbers of shots. Though the banned guns and magazines were used in only a modest fraction of gun crimes before the law, it was hypothesized that a decrease in their use might reduce gunshot victimizations, particularly those involving multiple wounds and/or victims. In response to a Congressional mandate for an impact assessment of the law, this study utilized national and local data sources and a variety of analytical techniques to examine the ban's short-term impact on gun violence. The ban may have contributed to a reduction in gun homicides, but a statistical power analysis of our model indicated that any likely impact from the ban will be very difficult to detect statistically for several more years. We found no evidence of reductions in multiple-victim gun homicides or multiple-gunshot wound victimizations. The findings should be treated cautiously due to the methodological difficulties of making a short-term assessment of the ban and because the ban's long-term effects could differ from the short-term impacts revealed by this study.     

Perceptions of coercion in interrogation: comparing expert and lay opinions

ABSTRACT

When confessions are entered into evidence in criminal courts, issues of coercion and voluntariness are important and often contested matters. Occasionally, defense attorneys proffer expert witnesses to testify about the coercive pressures of an interrogation and the risk of a false confession. Such testimony is often ruled inadmissible on the grounds that it does not inform the jury beyond its common knowledge. In our effort to test this judicial assumption about common knowledge, we surveyed jury-eligible laypeople (n?=?67) and social scientists specializing in interrogation and confessions (n?=?54) regarding their opinions about the coerciveness of prohibited interrogation tactics, maximization techniques, minimization techniques, and suspect risk factors and compared their ratings with a set of independent t tests. Laypeople gave lower ratings to the coerciveness of all sets of items representing interrogation techniques, and lower ratings to the vulnerabilities associated with suspect risk factors, as compared to social science experts. The disparities between laypeople’s and experts’ perceptions of coercion in interrogations demonstrate that such issues are not fully within the common knowledge of prospective jurors, and suggest the need to provide jurors with expert witness guidance when tasked with evaluating confession evidence.     

Canada,the Palestinian Liberation Organisation (PLO) and the flexibility of terror identities

ABSTRACT

Security governance practices are contingent on the imagination of future threats. The “war on terror” has produced a very narrow imagination of threats, almost singularly focused on suspect communities that are Arab, Muslim, or perceived to be Middle Eastern. Discussing how immigration practices in Canada have been influenced by counter-terrorism trends, we argue that “terror identities” are mutable and highly racialised imaginaries that cast indelible marks of suspicion on subjects who are deemed as security threats. Examining the case of a journalist deemed inadmissible to Canada because of her “membership” in the Palestinian Liberation Organisation (PLO), we argue that terror identities impose authoritative control over the status and lived experiences of individuals who are cast through these racialised labelling practices. Focussing on the shifting characterisation of the PLO by Canadian officials as both political interlocutor and terrorist organisation, our purpose is to highlight how racialised imaginations of terror identities enact punitive and discriminatory practices.     

Tales of the Bazaar: Interest-Based Negotiation Across Cultures

Interest-based negotiation, as popularized by Fisher, Ury, and Patton (1991), is a favored negotiation style of many people in the United States and other parts of the developed world. The author, an American attorney who has traveled widely, assesses how that approach works in different cultural contexts. Using illustrations from his own experiences, the author shows how interest-based techniques work successfully, as well as the limitations of this approach in some situations.     

Alcohol Prohibition and Cirrhosis

This article uses state-level data on cirrhosis death ratesto examine the impact of state prohibitions, pre-1920 federalantialcohol policies, and constitutional prohibition on cirrhosis.State prohibitions had a minimal impact on cirrhosis, especiallyduring the pre-1920 period. Pre-1920 federal antialcohol policiesmay have contributed to the decline in cirrhosis that occurredbefore 1920, although other factors were likely substantialinfluences as well. Constitutional Prohibition reduced cirrhosisby about 10–20%.
