More than two dozen San Diego county law enforcement agencies have started testing facial recognition technology used to help identify people in the field.

Currently, the software allows officers to compare any photo of your face to a database of local mug shots. But there are concerns about what may happen next.

Patrol cop Robert Halverson is one of seven officers in the Chula Vista Police Department who carries a tablet computer loaded with the facial recognition software, made by FaceFirst, LLC.

“This only taps into the county booking photos,” Officer Halverson said while demonstrating the software to CBS News 8.
