Itâs too early to say right now but I expect they are likely to go back on quite soon.â When turned on, live facial recognition cameras scan the biometrics of each person who walks past them. The technology then compares them with a watchlist of suspects, specially compiled for that deployment, and alerts nearby officers to any potential matches. Those officers are
