State of Arizona, Appellee v. Laquinn Anthony Fisher, Appellant

Summary

The court held that officers violated the Fourth Amendment by conducting a protective sweep of Fisher's apartment after Fisher and the other occupants had exited, because officers lacked specific and articulable facts supporting a reasonable belief that a dangerous person remained inside. The unaccounted-for assault weapon and the general possibility that someone else might be present were insufficient. The court vacated the court of appeals' decision and remanded to the trial court for further proceedings.
