Ongoing terrorist attacks in the Sahel region call for strengthening the security system by using human DNA identification technology. In this context, public opinion must be considered when establishing solid standards and universal safeguards for one of the most invasive forms of surveillance and profiling. For this purpose, we gathered internet users\' opinions in Burkina Faso (a country located in the Sahel region) on the use of DNA technology to support criminal investigations. The results revealed that 91.7% (431) of the 470 participants believed that this technology is currently necessary for the Burkina Faso\'s criminal justice system. However, the respondents expressed concerns about the custody and management of a national forensic DNA database. In this particular security setting, the public opinion of this study may provide leaders and political policymakers with clues for considering genetic fingerprints and implementing an national forensic DNA database to support criminal investigations in Burkina Faso whilst also considering the ethical implications.

This article combines linguistic discourse analysis with role theory to create a role-theoretic discourse analysis framework for German security policy. To illustrate this, we employ topos analysis on 30 plenary minutes of parliamentary debates regarding the International Security Assistance Force mission in Afghanistan, conducted by German Members of Parliament between 2001 and 2014. We interpret their perception of Germany\'s roles in light of key behavioral norms related to German security policy. The parliamentary discourse, shaped by topoi, sets the stage for decisions on German military operations abroad. The use of topoi is influenced by dominant thought patterns, particularly the perspective on Germany\'s role in security policy held by the political elite. Political decisions, in turn, reflect behavioral preferences guided by these viewpoints. Our research reveals how changes in German security policy are mirrored in the discourse. This discourse is structured around five categories of topoi for legitimizing or delegitimizing military operations abroad: necessity, obligation, self-interest, capability and preparedness, and solution. An evaluation of the use of topoi through the lens of role theory indicates that perceptions of Germany\'s role have evolved over time, encompassing roles such as a \"civilian power,\" a \"normal state,\" and an \"agenda-setting role\" in sync with its foreign military engagements.
