This report, undertaken within the frame of the Forensic Architecture project, is a spatial/temporal analysis of the events that led to the death of 63 migrants at sea off the coast of Libya in the spring of 2011. The release of the report will be included in a body of evidence submitted by a team of French NGOs (CIRÉ, FIDH, GISTI, LDH and Migreurop) in a legal case being filed against France for non-assistance at sea. The analysis focuses on how and why, in the midst of the Libya conflict, NATO failed to come to the aid of a vessel in distress that drifted for 14 days in what was arguably the most highly surveiled maritime area in the world. This project required the synthesis of disparate sources of data to reconstruct an accurate narrative of the space and time of what have become highly disputed events. It leverages the use of visualization technologies and techniques that have, to date, seen only limited applications in human rights analysis and reporting.
