Forensic architecture uses forensic science to draw conclusions from things happening on the ground, the changes and variations visible in a “before” and “after” photograph, projections, time lapse photography as well as shade cast on the ground and compares it to testimony from witnesses to the events to reach more accurate conclusions. The practice has been described as using "technology tools for justice". Amnesty International collaborated with Forensic Architecture in examining what really happened during the Gaza conflict in 2014.
