What are the four elements of arrest?

The correct choice outlines the four key elements of arrest: authority, intent, knowledge, and compliance.

Authority refers to the legal power a law enforcement officer has to make an arrest, which is typically grounded in statutes or regulations that empower them to enforce the law. Intent is the officer's intention to take a person into custody, indicating that the situation is serious enough to warrant an arrest. Knowledge relates to the officer's awareness of the facts and circumstances surrounding the arrest, which ensures that they are acting based on reasonable grounds rather than arbitrary decisions. Finally, compliance reflects the requirement of the individual being arrested to understand that they are being deprived of their liberty and must adhere to the officer's commands.

The other choices do not accurately capture the legal framework necessary for a valid arrest. For example, while reason, purpose, evidence, and intention might be related concepts, they do not encompass the comprehensive elements needed to establish an arrest as legally sound. Similarly, identification, warning, permission, and compliance focus on aspects that may occur during the interaction but do not necessarily structure the foundational elements defining an arrest. Legal grounds, evidence, intent, and warning partially align but miss out on the significance of the officer's authority and the necessity for the individual's knowledge and understanding
