Final answer:
The question is about the conditions under which Criminal History Record Information (CHRI) can be transmitted to field personnel, which indicates it should not be done through unencrypted means unless there's an immediate need for law enforcement purposes.
Step-by-step explanation:
The question pertains to the transmission of Criminal History Record Information (CHRI) to field personnel, which would generally be a law enforcement scenario. CHRI shall not generally be transmitted by unencrypted means, except in cases where circumstances reasonably indicate that immediate access to such information is necessary for law enforcement purposes.
In practice, this means sensitive information should always be handled with the highest security protocols unless an urgent situation arises that necessitates rapid dissemination of information to protect lives or assist in active law enforcement activities. It's imperative to ensure that CHRI is disclosed only to authorized individuals and in a manner that maintains the data's integrity and confidentiality.
