Facial recognition rules for Maryland police are due. ACLU says more protections are needed.

A fast-approaching deadline has the ACLU of Maryland calling for more protections as state police outline how local enforcement agencies will be able to use facial recognition technology. After years of debate on the use of the technology, which is often deployed as a surveillance tool in police investigations, legislation that put restrictions on facial recognition systems passed this year and was signed by Gov. Wes Moore in April.
