Final answer:
The TLETS and Nlets are secure networks exclusively used by law enforcement and criminal justice agencies to access and exchange critical information for their operations.
Step-by-step explanation:
The Texas Law Enforcement Telecommunication System (TLETS) and the International Justice and Public Safety Network (Nlets) are communication systems that are designed exclusively for use by law enforcement and criminal justice agencies. These secure networks allow police officers and federal law enforcement agents to access and exchange information pertinent to law enforcement operations and criminal investigations. For instance, through these systems, they can run checks on individuals, vehicles, guns, and other property, look up criminal histories, and communicate with other agencies across jurisdictions.
