I looked but I could not find a good write-up of the actual systems under discussion. “Large-scale, video-based” data fed through AI of some kind, details unspecified. Main points raised in defense were that it could identify unattended luggage (potential bombs) and dangerous crowd movements (potential stampedes). Presumably they also intend to do facial recognition and perhaps behavior analysis, and don’t want to mention those more contentious applications.
