What type of messages is the TIES computer prohibited from being used for?

The TIES computer system is specifically designed to enhance public safety and law enforcement efforts, which means its use is strictly regulated to ensure that it serves its intended purpose effectively. It is prohibited from being used for personal messages, as this could compromise the integrity and focus of the system. Personal use would divert resources away from essential law enforcement functions and could lead to privacy issues or misuse of data.

The other options pertain to legitimate uses of the TIES system. Emergency alerts are vital for public safety, and financial transactions, while perhaps not a primary function, are permissible if related to law enforcement activities. Criminal investigations directly align with the core mission of TIES, as the system is intended to support law enforcement agencies in their duties related to crime prevention and investigation. Thus, the prohibition against personal messages ensures that TIES remains an effective tool for its intended law enforcement applications.
