ProPublica: “…Axon, the nation’s largest provider of police cameras and of cloud storage for the video they capture, has a database of footage that has grown from around 6 terabytes in 2016 to more than 100 petabytes today. That’s enough to hold more than 5,000 years of high definition video, or 25 million copies of last year’s blockbuster movie “Barbie.” “In any community, body-worn camera footage is the largest source of data on police-community interactions. Almost nothing is done with it,” said Jonathan Wender, a former police officer who heads Polis Solutions, one of a growing group of companies and researchers offering analytic tools powered by artificial intelligence to help tackle that data problem. The Paterson, New Jersey, police department has made such an analytic tool a major part of its plan to overhaul its force…In August 2023, the Los Angeles Police Department said it would partner with a team of researchers from the University of Southern California and several other universities to develop a new AI-powered tool to examine footage from around 1,000 traffic stops and determine which officer behaviors keep interactions from escalating. In 2021, Microsoft awarded $250,000 to a team from Princeton University and the University of Pennsylvania to develop software that can organize video into timelines that allow easier review by supervisors…

One lesson has come through: Interactions that don’t end in violence are more likely to start with officers explaining what is happening, not interrupting civilians and making clear that cameras are rolling and the video is available to the public…”
