Video Data Analysis can be used for the detailed analysis of all types of events, including terrorist attacks. The NGO Forensic Architecture published a visual investigation of the racist terror attack in Hanau, Germany, on 19 February 2020, where nine people were murdered by a gunman. They combine and synchronise six CCTV camera perspectives and witness accounts to reconstruct the movement and movement speed of each person in the store during the attack. You can find a report on the investigation, including a video exposé, here.
