A mass surveillance system is being used by police departments nationwide to help solve crimes. The system, called Flock Safety, uses cameras to scan and log information about millions of cars. While the system has been used to catch serious criminals, it also raises concerns about incorrect identifications.

Further details about the system and its implications are available from InvestigateTV. InvestigateTV has more information on the Flock Safety system and its use by police departments, as well as related issues such as the care of retired police k-9s.
