Western Australia Police's new facial recognition technology made an unexpected arrest during a press conference on Thursday, as a wanted woman was detected among a crowd at Mirrabooka bus station in Perth's north. The woman, who allegedly failed to appear in court, was one of three people picked up by the real-time cameras, forcing officers to halt the media event to make the arrests.
Technology in Action
WA Police Commissioner Col Blanch said the incident demonstrated the effectiveness of the system. "Been happening all week," Blanch said. "I'd love to say I planned that, but I think that's exactly what the technology is. People are being arrested because they are wanted." The cameras, part of an Australia-first trial, have scanned over 130,000 faces since June 22, leading to 18 arrests in the first week alone. Sixteen of those arrests were for outstanding warrants, while two were for breaching exclusion orders in entertainment precincts.
How the System Works
The Overt Live Facial Recognition technology is mounted on or near a marked WA Police van. It scans crowds to instantly detect faces and compare them against a watchlist of wanted individuals or those banned from certain areas. If the system flags a potential match, a human officer makes the final assessment. Commissioner Blanch emphasized that "we have a human in the loop" to double-check false positives. Images of community members not on the alert list are automatically pixelated and deleted.
Community Response
Blanch noted that the community has largely responded positively to the trial. "Speaking to the team who have been setting this up for the last week, the overwhelming positive feedback from our community has been great to receive," he said. "That doesn't mean people haven't come up and showed concern, they have. But they've asked questions, they've had sensible discussions about what it does do and what it doesn't do." The trial is set to run for five months, but authorities are already impressed with the results. WA Police Minister Reece Whitby said, "I think the results send a very strong message about the effectiveness of this technology."
