We have a couple of license plate readers (LPR) in service that increase our effectiveness on the street. Small cameras are mounted on the squad car that read passing license plates and runs them for stolen cars, warrants and involvement in crimes. We plan on expanding the number of LPR's this year. I read a bulletin from last night that mentioned an officer was patrolling when his LPR alerted him to a passing stolen car. The officer pulled over the car and discovered the suspect had also committed at least one burglary.
It is through tools like LPR that police are more efficient and effective than ever before.
