What must an officer do while executing an arrest warrant?

When executing an arrest warrant, an officer is required to inform the defendant of the offense and the existence of the warrant. This procedure is crucial as it fulfills the legal obligation to notify the individual of why they are being arrested, ensuring that the arrestee is aware of the charges against them. This step is not only a matter of legal protocol but also aligns with the principles of transparency and due process.

Providing this information helps uphold the integrity of the law enforcement process, as it allows the defendant to understand their situation and prepares them for the next steps, which might involve legal representation or options for bail. While other choices reflect different aspects of arrest procedures, they do not encompass the fundamental requirement to inform the person about the basis of the arrest, which is key to the legitimacy of the arrest itself.
