During an argument with his wife, petitioner Edward Caniglia placed a handgun on the dining room table and asked his wife to “shoot [him] and get it over with.” His wife instead left the home and spent the night at a hotel. The next morning, she was unable to reach her hus-band by phone, so she called the police to request a welfare check. The responding officers accompanied Caniglia’s wife to the home, where they encountered Caniglia on the porch. The officers called an ambu-lance based on the belief that Caniglia posed a risk to himself or others. Caniglia agreed to go to the hospital for a psychiatric evaluation on thecondition that the officers not confiscate his firearms. But once Caniglia left, the officers located and seized his weapons. Canigliasued, claiming that the officers had entered his home and seized him and his firearms without a warrant in violation of the Fourth Amend-ment. The District Court granted summary judgment to the officers. The First Circuit affirmed, extrapolating from the Court’s decision in Cady v. Dombrowski, 413 U. S. 433, a theory that the officers’ removal of Caniglia and his firearms from his home was justified by a “commu-nity caretaking exception” to the warrant requirement.
Held: Neither the holding nor logic of Cady justifies such warrantless searches and seizures in the home. Cady held that a warrantless search of an impounded vehicle for an unsecured firearm did not vio-late the Fourth Amendment. In reaching this conclusion, the Court noted that the officers who patrol the “public highways” are often called to discharge noncriminal “community caretaking functions,” such as responding to disabled vehicles or investigating accidents. 413 U. S., at 441. But searches of vehicles and homes are constitutionallydifferent, as the Cady opinion repeatedly stressed. Id., at 439, 440– 442. The very core of the Fourth Amendment’s guarantee is the right
