Which of the following is NOT a method for obtaining an inmate's identification?

Relying on an inmate to self-identify can be problematic due to various factors such as potential deception, confusion, or lack of knowledge regarding personal information. While asking the inmate is a method that might be used in some circumstances, it is not a reliable or standardized approach for confirming an individual’s identity, especially in a correctional setting.

In contrast, using a driver's license, running a computerized criminal history, or contacting a local agency for a mug shot are all established methods that prioritize accuracy and verification. A driver's license provides concrete identification, computerized histories offer a comprehensive overview of a person's criminal record, and mug shots serve as visual confirmation of identity. These other methods are grounded in systematic processes that reduce the risk of error and enhance security protocol, making them preferable over self-identification by inmates.
