United States v. Banks
Citation and Court
540 U.S. 31 (2003) — Supreme Court of the United States
Facts
Officers arrived at Banks’s apartment with a search warrant for drugs and cocaine. They knocked and announced their presence, then waited 15 to 20 seconds before forcibly entering. Banks was in the shower and claimed he did not hear the knock. Drugs were found. He argued the wait was too short.
Issue
Whether officers executing a search warrant for drugs who wait 15 to 20 seconds before forcing entry comply with the knock-and-announce requirement.
Holding
Yes; a 15 to 20 second wait before forced entry was reasonable given the exigency created by the nature of the evidence — drugs can be quickly destroyed — and the circumstances indicating Banks was home.
Rule / Doctrine
The knock-and-announce rule requires police to knock, announce their authority and purpose, and wait a reasonable time before entering. Reasonableness depends on the totality of circumstances: the type of evidence, the risk of its destruction, and the time of day. Drug investigations carry inherent exigency because narcotics can be rapidly flushed or destroyed, justifying a shorter wait than might otherwise be required.
Significance
Confirmed that the adequacy of a knock-and-announce wait is determined contextually, not by a rigid time rule. Drug cases inherently support shorter waits given destruction risk, significantly affecting the practical scope of the knock-and-announce protection.
