governmental intrusion.” Silverman v. United States, 365 U.S. 505, 511, 81 S.Ct. 679, 5 L.Ed.2d 734 (1961). Indeed, the “physical entry of the home is the chief evil against which the wording of the Fourth Amendment is directed.” United States v. U.S. Dist. Ct., 407 U.S. 297, 313, 92 S.Ct. 2125, 32 L.Ed.2d 752 (1972). Thus, “[i]t is a basic principle of Fourth Amendment law that searches and seizures inside a home without a warrant are presumptively unreasonable.” Payton v. New York, 445 U.S. 573, 586, 100 S.Ct. 1371, 63 L.Ed.2d 639 (1980) (internal quotation marks omitted).
However, this presumption can be overcome. “[Bjecause the ultimate touchstone of the Fourth Amendment is ‘reasonableness,’ the warrant requirement is subject to certain exceptions.” Brigham City v. Stuart, 547 U.S. 398, 403, 126 S.Ct. 1943, 164 L.Ed.2d 650 (2006). Two exceptions are relevant here.
First, under some circumstances, a police officer can search without a warrant while performing “community caretaking functions.” Cady v. Dombrowski, 413 U.S. 433, 441, 93 S.Ct. 2523, 37 L.Ed.2d 706 (1973). In Dombrowski, the defendant, a Chicago police officer, was in an automobile accident in Wisconsin. Believing that Chicago policemen were required to carry their service revolvers at all times, local police officers searched the defendant’s disabled and towed car in order to find the revolver, as it was standard procedure in their department to remove weapons from vehicles in order “to protect the public from the possibility that a revolver would fall into untrained or perhaps malicious hands.” Id. at 443, 93 S.Ct. 2523. Because the search was a result of a function “totally divorced from the detection, investigation, or acquisition of evidence relating to the violation of a criminal statute,” it was permissible. Id. at 441, 93 S.Ct. 2523. Although Dombrowski involved the search of a vehicle, some lower courts have relied on the community caretaking rationale in upholding warrantless searches of homes. United States v. Quezada, 448 F.3d 1005, 1007 (8th Cir.2006); United States v. Stafford, 416 F.3d 1068, 1073 (9th Cir.2005); United States v. Rohrig, 98 F.3d 1506, 1521-22 (6th Cir.1996). But see United States v. Bute, 43 F.3d 531, 535 (10th Cir.1994) (holding that community caretaking exception applies only to automobile searches); United States v. Pichany, 687 F.2d 204, 208-09 (7th Cir.1982) (same).
Second, even when not performing a community caretaking function, a police officer may search a home without a warrant if, in an emergency, “ ‘the exigencies of the situation’ make the needs of law enforcement so compelling that the warrantless search is objectively reasonable under the Fourth Amendment.” Mincey v. Arizona, 437 U.S. 385, 394, 98 S.Ct. 2408, 57 L.Ed.2d 290 (1978) (quoting McDonald v. United States, 335 U.S. 451, 456, 69 S.Ct. 191, 93 L.Ed. 153 (1948)). For example, law enforcement officers in hot pursuit of a suspected felon may chase their quarry into a home without seeking judicial authorization. Warden v. Hayden, 387 U.S. 294, 87 S.Ct. 1642, 18 L.Ed.2d 782 (1967). They may enter a dwelling to prevent the imminent destruction of evidence. Ker v. California, 374 U.S. 23, 83 S.Ct. 1623, 10 L.Ed.2d 726 (1963). Firefighters may enter a burning building to combat a blaze, and may remain for a reasonable time after the fire to investigate its cause and look for evidence of arson. Michigan v. Tyler, 436 U.S. 499, 98 S.Ct. 1942, 56 L.Ed.2d 486 (1978). In each of these situations, “there is compelling need for official action and no time to secure a warrant,” id. at 509, 98 S.Ct. 1942, making a warrantless entry reasonable.
