Working on a project of the Financial Times, students of the Open Source Global Justice Investigations lab used open-source techniques, including geolocation, weapons identification, and social media analysis, to contribute to an investigation on Haiti’s gang crisis. In this podcast, Casper Baehr, Lars Brull, Alix Convent, Constanza Mottin, and Ronan Verbeek explain what methods they used, what challenges they faced, and how they worked together during their research. (Note: this podcast was recorded before the project was finalized).
