Under which Penal Code is providing false identifying information to a peace officer addressed?

Providing false identifying information to a peace officer is specifically addressed under Penal Code 148.9 PC. This statute outlines the unlawful act of knowingly providing false information about one's identity during the course of an investigation or when a peace officer is performing their duties. The law aims to ensure that peace officers can accurately identify individuals, which is critical for maintaining public safety and effective law enforcement.

In contrast, other Penal Code sections mentioned do not pertain to this specific offense. For example, Penal Code 148(a)(1) involves resisting or delaying a peace officer's duties, while Penal Code 187 covers homicide, and Penal Code 203 pertains to mayhem. These do not relate directly to the act of providing false identification during an interaction with law enforcement. Thus, 148.9 PC is correctly identified as the relevant code for this situation.
