What crime is defined as the unlawful taking of a prisoner from an officer or place of confinement?

The crime that is defined as the unlawful taking of a prisoner from an officer or place of confinement is known as "Rescue." This term specifically refers to actions where someone attempts to free a prisoner or detainee from custody without lawful justification. It emphasizes the unauthorized interference with lawful detention, distinguishing it from other crimes.

Kidnapping typically involves taking someone against their will, often with the intent to hold them for ransom or another illegal purpose. Assault generally pertains to causing physical harm or the threat of such harm to another person rather than the act of taking someone from custody. Theft involves taking someone else's property with the intent to permanently deprive them of it and does not apply in the context of detaining or transferring individuals. Therefore, "Rescue" is the precise term that encapsulates the act of unlawfully removing a prisoner, which is why it is the correct answer.
