Footage of police firearms officer training has been released as part of the Metropolitan Police’s work with Facebook to improve detection of live-streamed Christchurch-style terrorist attacks. The force hopes the videos will help the social network develop technology that can identify terrorist live streams so the company can tip police off about attacks early on and prevent them being broadcast. The tech giant provided officers at the Met’s firearms training centres with body cameras and the footage will be shared to help its artificial intelligence more accurately and rapidly identify videos of real-life first person gunman incidents. Facebook came under fire for the spread of a live stream video showing the New Zealand mosque shootings in March, which left 51 dead. The video was viewed fewer than 200 times during the live broadcast and was watched about 4,000 times in total before being removed.
