Which of the following is NOT included in NCIC Messages?

In the context of NCIC messages, there are specific types of messages that are utilized for maintaining and querying the data contained within the system. Entry, Inquiry, and Cancel are all standard types of messages used in NCIC operations.

An Entry message is used to add a record into the NCIC database, such as entering information about a stolen vehicle or a missing person. An Inquiry message allows users to search for and retrieve information based on specific criteria, like querying the status of a person or property. Finally, a Cancel message is employed to remove or invalidate a previously entered record, ensuring that outdated or incorrect entries do not persist in the database.

While updates to existing records are a crucial part of data management, they are typically not referred to as an "Update" message within NCIC terminology. Instead, modifications to records are generally included in the Entry message type, which can also serve to update existing information when necessary. This distinction is important in understanding the mechanics of how NCIC operates and organizes its messaging structure.
