Where this applies
A Maryland statute binding police officers and other employees of law enforcement agencies, approved on 16 May 2024 and in force from 1 October 2024. Results generated by facial recognition technology may not serve as the sole basis to establish probable cause or the positive identification of an individual in a criminal investigation or proceeding, and before being used for any purpose in a criminal investigation a result shall be independently verified by an individual who has completed the required training. It governs how an investigative lead from a machine may be used and requires a person to check it; it does not measure how often facial recognition is used or how investigations have changed.
What this means
Where a machine now suggests who someone is, the law in Maryland keeps the investigation with people: the match cannot carry the case alone, and a trained person must check it before it is used at all.
What it does not yet show
It is one state's law about one technology; it does not show how often police use facial recognition or whether verification is done well.
What you can check
Open Maryland Chapter 808 of 2024 (SB 182) and find "RESULTS GENERATED BY FACIAL RECOGNITION TECHNOLOGY MAY NOT SERVE AS THE SOLE BASIS TO ESTABLISH PROBABLE CAUSE".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
