Western Australia trial of facial recognition scans over a million faces, leads to 122 arrests

The Guardian reported that a five‑month trial of real‑time facial recognition technology in Western Australia scanned 1,380,882 faces. Police deployed surveillance vans 100 times across 43 regional and metropolitan sites, using the system to compare images against a database of known offenders.

During the trial, officers acted on 146 matches involving registered sex offenders, which resulted in 122 arrests. The technology also generated nine false alerts, prompting police to investigate those instances.

The trial concluded on Saturday, marking the largest deployment of live facial‑recognition scanning in the state to date. Officials said the operation demonstrated the system’s ability to identify suspects quickly, while also acknowledging the need to address the occasional incorrect alerts.

Why it matters

The trial shows how large‑scale facial‑recognition can aid law enforcement but also highlights the risk of false alerts that require careful oversight.
