  • 2 for an organization

    The Inspector General found that in-car alerts led officers to 337 stolen vehicles, 24 stolen plates and 74 arrests in two months.

  • Not rated a person

    The report counts recovered vehicles and does not say whether or when their owners got them back.

  • Not rated society

    The report does not measure whether the alerts reduced vehicle theft or other crime, and 161 confirmed matches flagged vehicles that were not stolen.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

An independent audit report supports the benefit.

The system’s part
Not isolated. The Inspector General counted the outcomes that officers recorded after in-car alerts and made no comparison with patrols without plate readers. The report says that the software turns each plate photo into searchable data and that letters, numbers or the state can be misread. It does not say how the Axon cameras read plates or whether they learned from data. A Flock agreement in its appendix lets Flock train machine learning algorithms on anonymized city data.

    Office of the Inspector General, Los Angeles Police Commission. Review of the Los Angeles Police Department's Automatic License Plate Reader System and Use in the Field (BPC #26-184), 10 July 2026. Section IV.D, p. 16. The OIG analyzed Axon in-car alert data for 1 August to 30 September 2025.

    The OIG found that during the two-month review period, 337 stolen vehicles were recovered without incident.
    The OIG identified 74 arrests resulting from 68 stops generated by Hot List alerts.
    During the review period, officers acknowledged 161 alerts as accurate license plate matches; however, subsequent investigations determined the vehicles were not stolen.

Details

AI system

Workflow

The ALPR feature of Axon's in-car video system scanned plates whenever a patrol car was on and compared them with Hot Lists in real time. Alerts appeared on the car's mobile computer, and policy required officers to try to verify an alert before a stop. The Inspector General removed duplicate alerts and checked arrest stops against body-worn video and reports.

Follow-up

Conditions for replication

Hot Lists must be updated promptly when a vehicle is recovered or is no longer wanted. Officers must record the action taken after each alert for the outcomes to be counted.

Entry details

Sector

Policing / stolen vehicle recovery.

Purpose

Axon built the ALPR feature of its in-car video system to read the plates of passing vehicles and alert officers to plates on Hot Lists.
