What is the purpose of the "knock-and-announce" rule?

The "knock-and-announce" rule serves to protect an individual's privacy and to prevent unnecessary confrontations between law enforcement and residents. The primary objective of this rule is to provide occupants of a dwelling with notice of the police's presence and purpose before they forcefully enter. This notice allows individuals the opportunity to comply with the law and prepare for the police’s entry, reducing the likelihood of confusion or panic that could lead to a violent confrontation.

Additionally, this rule underscores the importance of respecting the sanctity of the home, highlighting the balance that must be maintained between law enforcement authority and individual rights. By adhering to this rule, officers demonstrate a commitment to lawful policing and the protection of constitutional rights. In this context, the other options do not reflect the essence of the "knock-and-announce" rule, as it is not designed to expedite police procedures or circumvent legal requirements such as warrants, nor is its primary purpose to prevent evidence destruction.
