What does the "knock and notice" principle entail?

The "knock and notice" principle requires law enforcement officers to announce their presence before entering a property. This principle is rooted in the respect for individuals' privacy and property rights, serving as a safeguard against unreasonable searches and seizures. By announcing themselves, officers provide the occupants an opportunity to comply with the law, allowing them to grant permission for entry or to prepare for the officers' arrival. This principle underscores the importance of transparency and accountability in law enforcement actions, helping to maintain the balance between public safety and individual rights.

The other options suggest actions that do not align with this legal framework, such as breaking down doors without prior notice or entering without notification, which would violate the established protocol aimed at protecting citizens' rights.
