What must an officer do if admittance is denied after announcing their authority?

An officer may proceed with a no-knock entry under specific circumstances when admittance is denied after announcing their authority. This approach is typically used when there is a reasonable belief that waiting to gain entry would pose an immediate threat to public safety, the officer's safety, or evidence may be destroyed. However, such actions should be justified and in compliance with applicable laws and regulations.

No-knock entries are generally limited to situations where the officer can articulate a clear and immediate risk, such as the potential for violence or the imminent destruction of evidence. Prior to executing a no-knock entry, the officer should ensure that they adhere to department policies and legal standards regarding such actions to avoid infringing on constitutional rights.

This choice reflects an understanding of the necessity for swift action in certain law enforcement situations, but it must be balanced with the legal principles that govern entry and search. Ensuring that these actions are justified is key to maintaining lawful enforcement and protecting public safety.
