Prevalence of organic gunshot residues in police vehicles

The present study investigated the organic gunshot residue (OGSR) background level of police vehicles in Switzerland. Specimens from 64 vehicles belonging to two regional police services were collected and analysed by LC-MS in positive mode. The driver’s and back seats were sampled separately to monitor potential differences between locations and to assess the risks of a suspect being contaminated by OGSR during transportation to a police station.The results showed that most of the 64 vehicles were uncontaminated (44 driver’s seats and 38 back seats respectively). Up to six of the seven targeted compounds were detected in a single sample, once on a driver’s seat and twice on back seats. The contamination frequency generally decreased as the number of compounds detected together increased. The amounts detected were in the low ng range and less than amounts generally detected just after discharge on a shooter. Our data indicated that detecting a combination of four or more compounds on a police vehicle seat appears to be a relatively rare occurrence. The background contamination observed was most probably due to secondary transfer from police officers (e.g. through recent participation in a shooting session or firearm manipulation) or from firearms stored in the vehicles. The present results might be used as a recommendation to minimize contact of a suspect with contaminated surfaces if OGSR is implemented in routine work in parallel to IGSR analysis.     

Gaughran vs the UK and public acceptability of forensic biometrics retention

This commentary provides a response to the European Court of Human Rights ruling in the case of Gaughran vs the United Kingdom on 13 February 2020. The Court ruled that the indefinite retention of DNA, fingerprints and facial images from all convicted adults was disproportionate. Using data from a survey on public attitudes, we examine the public acceptability of the police retention of forensic biometrics from the population.

Investing in multi-stakeholder dialogue to address natural resource competition and conflict

How can multi-stakeholder dialogue help assess and address the roots of environmental resource competition and conflict? This article summarises the outcomes and lessons from action research in large lake systems in Uganda, Zambia, and Cambodia. Dialogues linking community groups, NGOs and government agencies have reduced local conflict, produced agreements with private investors, and influenced government priorities in ways that respond to the needs of marginalised fishing communities. The article details policy guidance in four areas: building stakeholder commitment, understanding the institutional and governance context, involving local groups in the policy reform process, and embracing adaptability in programme implementation.

Accountability mechanisms in community-driven reconstruction in eastern Democratic Republic of Congo

A lack of accountability is often considered a root cause of conflict. Many post-conflict reconstruction efforts therefore aim to enhance accountability between authorities and the population through community-driven reconstruction programmes. This article examines the accountability mechanisms in the Tushiriki community-driven reconstruction programme in eastern Democratic Republic of Congo. The ethnographic research found little impact of formal programme accountability. Rather, accountability was shaped differently and had its own context-specific meaning. To make accountability more sustainable, stronger embeddedness in local institutions and more appropriate translations of abstract concepts into the local context are needed.     

Negotiating justice: legal pluralism and gender-based violence in Liberia

The plural legal system in post-conflict Liberia expresses tensions between modern and customary institutions. This article seeks to understand how Liberians navigate choices in the plural legal system to address gender-based violence cases. By asking how and why people make the choices they do, we highlight how Liberians solve tensions between institutions, by creating flexible categories that allow them to pursue a course of action that does not compromise their ability to access social networks and resources.     

Agriculture in and beyond the Haitian catastrophe

Although the devastation from Haiti’s 2010 earthquake was concentrated in Port-au-Prince, it had deep agrarian roots. This paper situates Haiti’s urban poverty in the chronic exploitation of the country’s peasant classes as a basis for assessing the competing contemporary visions for agricultural development. We argue that the post-earthquake reconstruction has fortified a neoliberal development that is incompatible with the aspirations of the Haitian peasantry. Given the interrelated power of domestic elites and international donors, and the proliferation of disconnected development projects, we conclude that any prospect for pro-poor development hinges on the growth and collaboration of peasant movements.     

‘Whichever way you turn,there is the face of God’ diaspora,memory, and historiography from the margin in The Moor’s Account by Laila Lalami

In The Moor’s Account, Laila Lalami dares to dust off the archive of official history that passed over the testimonies of a Moroccan slave during the Discovery Age. This paper explores the way the slave capitalizes on historiography to reconstruct the Western monolithic history. In so doing, the re-constructor’s memory performs a number of roles. It registers the history of the European conquest of La Florida using micro narrative frameworks that highlight salient differences from the official record. Besides, the diasporic memory that the present novel advocates has the intention to mark a difference of the silenced subjectivity from the supremacist histories through a transnational matching of homeland with diaspora. This transnationalism is coupled with a look forward to circumvent the essentialism implied in the monologic narratives. In shuttling between the past, present, and future, memory espouses cosmopolitanism as an alternative to the fundamentalism which threatens people’s cultural diversity.
