United States v. Banks

Background

Officers obtained a warrant to search a man named Banks’s two-bedroom apartment for cocaine. They knocked, announced “police search warrant,” and after hearing no response and waiting 15 to 20 seconds, they forced the front door open. Banks, who said he was in the shower and heard nothing until the door crashed, was confronted and the search uncovered crack cocaine, weapons, and other evidence. Banks moved to suppress the evidence; a divided Ninth Circuit ordered suppression, and the Government appealed to this Court.

Reasoning

The core question was whether waiting 15 to 20 seconds after a proper knock and announcement was reasonable before a forcible entry to prevent loss of evidence. The Court applied a fact-based “totality of circumstances” approach. It explained that officers may reasonably suspect that someone inside will quickly dispose of easily flushed or thrown-away drugs, and that the officer’s perspective and the facts they knew at the door control the decision. The Court rejected the Ninth Circuit’s rigid list of factors and categorical time rules, and held that a brief wait here was not unreasonably short. The Court also said the criminal statute governing breaking in after notice, 18 U.S.C. §3109, allows the same exigent exception when evidence is about to be destroyed.

Real world impact

This ruling makes clear that, in drug-search situations, officers can lawfully force entry after a short wait when they reasonably suspect imminent destruction of evidence. It narrows categorical timing rules, focuses on what officers knew at the moment, and allows forcible entry under both the Constitution and the statute when exigency ripens.
