Which file is NOT part of the MULES system?

The file that is not part of the MULES system is property records. MULES focuses on law enforcement and public safety, prioritizing law enforcement data relating to vehicle registration, license plates, and personal information connected to criminal activity or enforcement efforts. It provides officers and authorized personnel with critical information that aids in the investigation and management of cases.

Vehicle parts reference is integrated into the MULES framework, as it relates to stolen vehicle parts which can be crucial in investigations. License plates are also a fundamental component of MULES because they help track vehicles in the context of law enforcement activities. Person records are vital for identifying individuals involved in criminal activities or investigations and are maintained within MULES for the necessary background checks for law enforcement purposes.

In summary, property records, while important in broader contexts of law enforcement and asset management, do not pertain directly to the functions covered by MULES, making them the correct answer in identifying the file that is not included in the MULES system.
