What transaction query is used to search the LESC database?

The query used to search the Law Enforcement Service Center (LESC) database is the IAQ, which stands for "Interstate Alert Query." This specific query is designed to retrieve information from the LESC database, allowing law enforcement personnel to access vital data related to various alerts and transactions that may be relevant during their investigations or operations. Utilizing the IAQ enables officers to compile information from multiple jurisdictions, ensuring that they have a comprehensive view of any pertinent issues they might be facing.

The IAQ is particularly important because it helps in tracking wanted persons, stolen vehicles, and other critical alerts that originate from different states. Its specialized function shows its significance in facilitating effective communication and collaboration among law enforcement agencies across state lines.

Other options do not pertain to the LESC database searches: UQ stands for "Uniform Query," BQ refers to "Basic Query," and RQ is known as "Registration Query." Each of these has distinct purposes within law enforcement data systems but does not specifically target the LESC database like the IAQ. Thus, the IAQ query is the correct choice for accessing the necessary information in the LESC database.
