Automated license plate reader technology (ALPR) may be used to support a wide range of public safety activities including revoked/suspended driver interdiction, stolen vehicle recovery, enforcement of traffic regulations, apprehension of individuals subject to an outstanding warrant, and criminal and terrorist investigations/interdiction. ALPR devices enable police officers to recognize and take immediate action against vehicles and persons who are subject to investigative detention or arrest; the data collected by ALPRs can also provide investigative leads to identify unknown vehicles, to gather data about known suspect vehicles and to locate potential suspects, witnesses or victims in the vicinity of a crime scene. (07/29/15)
The content of this policy will provide MPD personnel with guidelines and procedures for the use, retention, access, handling of evidence, and requests for and release of data captured by ALPR equipment. (07/29/15)
Any use of an ALPR system by the Minneapolis Police Department shall be in compliance with MN Statute 13.824 and any other applicable statutes. MPD employees shall be responsible for performing all ALPR related duties in accordance with the Automated License Plate Reader (ALPR) Policy and state law. All MPD employees who have access to an ALPR device or the ALPR database shall receive training on these systems. Training may include, but not be limited to: department policy, directives, electronic or traditional classroom education. (07/29/15)
All ALPR devices and data generated by the use of the ALPR devices shall only be used for legitimate law enforcement business.
Automated License Plate Reader (ALPR): A system consisting of a camera or cameras and related equipment that automatically and without human control locates and focuses on, and photographs license plates and vehicles that come into the range of the device, that automatically converts digital photographic images of scanned license plates into electronic data, that is capable of comparing scanned license plate text data with data files for vehicles on a BOLO (be on the lookout) or hot list programmed into the device’s electronic memory, and that notifies police when a scanned license plate matches the license plate on a programmed BOLO list. The term includes both devices that are placed at a stationary location and mobile devices affixed to a vehicle and capable of operation while the vehicle in in motion.
BOLO (Be on the lookout): A determination by a law enforcement agency that there is a legitimate and specific law enforcement reason related to an active criminal investigation to identify or locate a particular vehicle. (07/29/15)
BOLO List/ Hotlist: A compilation of license plates or partial license plates of vehicles for which a BOLO situation exists that is programmed into an ALPR so that the device will alert if it captures the image of a license plate that matches a license plate included on the list.
Stored Data: All information captured by an ALPR and stored in the device’s memory or in a separate storage device or system. This includes the recorded image of a license plate which has been read, optical character recognition data, a contextual photo of the vehicle, GPS data, ALPR device data, timestamp and hotlist information. This term refers to both alert data and non-alert data.
Alert data: Information captured by an ALPR relating to a license plate that matches the license plate on a BOLO or Hotlist.
Read: The process by which an ALPR automatically focuses on, photographs, and convers to digital text the license plate of a vehicle that comes within range of the ALPR device. The term scan may also be used.
Authorized User: A sworn or civilian employee who has been authorized to operate an ALPR device or to access ALPR stored data and who has successfully completed training on ALPR use and policy.
Designated Supervisor: A superior officer assigned to oversee and administer, or to assist in overseeing and administering, the use of the ALPR devices and/or stored ALPR data. There may be more than one designated supervisor.
Historical ALPR query: The process of accessing and reviewing stored ALPR data to gather information about known vehicles, to identify unknown vehicles and/or to identify vehicles in the area of a crime scene.
