Wilson v. Arkansas

Background

A woman suspected of selling drugs, Sharlene Wilson, shared a home with Bryson Jacobs. In November and December 1992 she sold marijuana and methamphetamine to an informant working for the Arkansas State Police. On December 30 the informant met the woman at a store; she produced a semiautomatic pistol, threatened to kill the informant if she was working for police, and then sold marijuana. The next day officers obtained warrants to search the home and arrest both occupants. When officers later executed the warrant they entered through an unlocked screen door, identified themselves and said they had a warrant while entering, found drugs, a gun, and the woman flushing marijuana, and arrested both.

Reasoning

The Court reviewed whether a long-standing common-law practice — that officers generally should announce their presence before breaking into a dwelling — is part of the Fourth Amendment’s requirement that searches be reasonable. Looking to English and early American sources, the Court held that knock-and-announce is part of the reasonableness inquiry. But the Court emphasized the rule is not absolute; officers may enter without announcing when safety, pursuit, or likely destruction of evidence justifies immediate entry. The Court reversed the Arkansas Supreme Court and sent the case back so state courts can decide whether the officers’ unannounced entry was reasonable under the circumstances.

Real world impact

This decision means that courts must consider whether police announced themselves before entering homes when deciding if a search was reasonable. It recognizes clear exceptions and does not automatically bar evidence when officers fail to announce. The ruling remands the specific case for factfinding about threats and evidence destruction, so its effect on Wilson’s conviction will depend on the state court’s further findings.
