“Phoenix police officers are patrolling streets with a new secret weapon… It’s an automated license plate reader. Cameras mounted on top of police cars are taking pictures of plates, then comparing them to a database of stolen vehicles. They can read up to 50,000 plates in only a few hours.
Phoenix PD is vague about the automated reader’s capabilities as to whether they are only using it with a stolen vehicle database, or with other “watchlists” such as expired tags, expired registrations, outstanding parking tickets, etc.
Thanks to Mike for bringing this article to our attention in the comments section.
