If a witness provides a false address and birthday to law enforcement, what offense have they committed?

When a witness provides a false address and birthday to law enforcement, they are committing the offense of failure to identify. This aligns with legal statutes that require individuals to provide accurate identifying information to law enforcement officials. Failure to comply by giving false information can lead to charges, as the act can obstruct law enforcement's ability to verify identities or investigate further.

The situation becomes problematic because accurate identifying information is critical for various investigative procedures, including confirming a witness's background or other relevant legal matters. The emphasis is on the legal responsibility of individuals to provide truthful information when interacting with law enforcement.

The other options do not specifically capture the nature of providing false information in this context. Obstruction of justice relates to broader actions that hinder legal proceedings. False testimony typically refers to lying under oath in a legal setting, while assault involves physical harm to another individual and is not relevant here. Thus, the charge of failure to identify accurately reflects the witness's actions in providing false information.
