Judge SOTOMAYOR dissents in a separate opinion.
JACOBS, Circuit Judge:
The United States appeals from orders of the United States District Court for the Southern District of New York (Patterson, J.) granting defendants-appellees’ motions to suppress evidence, and denying the government’s motion for reconsideration. In a nutshell, police officers who were on surveillance in the hallway of an apartment building, watching the door of a narcotics stash house, were surprised by the arrival of a woman delivering an order of hot food to the stash house. They allowed her to follow through on her delivery, and through the opened door directed that the occupants step outside and submit to a brief investigatory detention. The district court held that the police thus made a constructive entry into a private residence in violation of the Fourth Amendment’s warrant requirement.
We reverse, holding (1) that occupants of a known stash house, having voluntarily exposed themselves to public view by answering the door to receive their food delivery, had no reasonable expectation of privacy against being seen by persons standing in a public hallway; and (2) that once they were seen, in the absence of unreasonable police conduct, the occupants’ temporary seizure in the course of a limited investigation does not constitute a violation of the Fourth Amendment.
BACKGROUND
The district court opinions in this ease are reported at United States v. Gori, No. 98 CR. 1163(RPP), 1999 WL 322651 (S.D.N.Y. May 20, 1999) (granting defendants-appellees motion to suppress) (“Gori I”); and United States v. Gori, No. 98 CR. 1163(RPP), 1999 WL 816172 (S.D.N.Y. Oct.13, 1999) (denying government’s motion for reconsideration) (“Gori II ”). We assume familiarity with the facts as set out at length by the district court, and recount in this opinion only such facts as bear upon our resolution of the issues presented on appeal.
[47]*47A. Facts
Pedro Mora was arrested in possession of a kilogram of cocaine on October 12, 1998, and immediately cooperated with the police. Mora paged his drug source, defendant Julio Gori, who called back. As police officers listened in, Mora told Gori that he had two customers and wanted to pick up two kilos of cocaine. Gori agreed and invited Mora to come by later that afternoon.
Accompanied by two New York City police officers, Mora went to the apartment building Mora identified as the location where Gori had delivered kilogram quantities of cocaine to Mora in the past. From an unmarked car, Det. Amando Rodriguez and Sgt. Diane Contreras watched as two men entered the building. Mora identified one as Gori; the other was later identified as defendant-appellee Sorin Pi-chardo. Det. Rodriguez left the car, followed both men, and saw them enter Apartment 1M.
Mora telephoned Gori fifteen minutes later to say that he was waiting in front of the building. Gori then came out of the building carrying a small black shopping bag and approached what he thought was Mora’s parked vehicle. Coming up from behind Gori, Det. Rodriguez displayed his shield, and said “Police, stop!” Gori froze and dropped the bag, and Sgt. Contreras moved in to place Gori under arrest. Det. Rodriguez discovered two yellow packages in the bag, each of which contained a kilo of cocaine. Gori said in Spanish that someone in the apartment building had given him the bag.
Det. Rodriguez, Sgt. Contreras and another officer set up surveillance in the lobby of the apartment building pending further instructions from their lieutenant, who was not there yet. Twenty to thirty minutes passed; no one entered or left Apartment 1M; and the lieutenant did not arrive. At that point, a woman entered the apartment lobby with a delivery order of hot food for Apartment 1M. According to Det. Rodriguez’s testimony, he worried (1) that if he prevented the delivery, the hungry occupants might investigate the delay and be alerted to the officers’ presence, and (2) that if he let the delivery be made, the delivery woman might betray their presence, inadvertently or otherwise. Det. Rodriguez and Sgt. Contreras decided to accompany the delivery woman to Apartment 1M.
The delivery woman stood in front of the door to Apartment 1M, with Det. Rodriguez to her left, and Sgt. Contreras just off to the right. Both officers had their guns drawn but at their sides and pointed to the floor. The delivery woman knocked on the door, and the door was opened wide. Both officers immediately displayed their shields, and Det. Rodriguez said, “Everyone step out into the hallway!” Det. Rodriguez testified that from his spot in the hallway, he could see five people through the open door (two men, two women and a child), including defendant-appel-lee Victor Rosario. A moment later, Pi-chardo (who had earlier been observed arriving at the apartment building with Gori) emerged from a bedroom in the rear of the apartment. All six occupants stepped into the hallway, where they were told to stand against the wall. Sgt. Contreras testified that at this point the occupants were not free to leave.
The officers re-holstered their weapons and brought a handcuffed Gori into the hallway area. Det. Rodriguez asked the occupants who owned Apartment 1M. Rosario identified himself as the owner of the apartment, at which point Det. Rodriguez asked Rosario if he knew “the fat guy,” motioning at Gori. Rosario looked at Gori, nodded and hesitated. Then, either Rosario or Det. Rodriguez (it is unclear on the present record) asked to speak in private. Rosario moved back into the apartment and Det. Rodriguez and Sgt. Contreras followed. Rosario then told both officers that “[t]he only thing I know” aboüt Gori “is that he gave me a thousand dollars to hold a bag for him.” [48]*48Rosario then consented to a search of the apartment, and Det. Rodriguez prepared a handwritten consent to search form, which Rosario signed.1 Det. Rodriguez asked Rosario about the bag he was holding for Gori, and Rosario took Det. Rodriguez and’ Sgt. Contreras to the bedroom where he opened an armoire and pulled out a bag containing five kilograms of cocaine. The officers left the bag in the armoire and returned to the hallway to maintain control of the other occupants.
A half-hour later, New York Police Department (“NYPD”) Lieutenant Ciaran Ti-money arrived bearing a Spanish-language consent-to-search form of the kind used by the Drug Enforcement Agency (“DEA”). Det. Rodriguez handed the form to Rosario, advised him to read it, and explained it to him. Rosario signed the form and the officers conducted a full search of the apartment, beginning with the armoire. Seized from the apartment were five kilograms of cocaine as well as dilutants, documents, drug paraphernalia and $15,000 in cash. The officers placed Rosario and Pi-chardo under arrest, and transported them (and Gori) to the DEA’s offices, where all three defendants were read Miranda warnings. Pichardo signed a form waiving his rights and stated that he knew that the other defendants were drug dealers but claimed that he did not know that there had been drugs in the apartment at that time.
B. Motion to Suppress
In indictments returned on October 22, 1998, Gori, Rosario and Pichardo were charged with conspiracy to distribute cocaine, in violation of Title 21, United States Code, Section 846. Pre-trial, Rosario and Pichardo moved to suppress the physical evidence seized from Apartment 1M and the statements that they made, on the grounds (1) that the police entered the apartment in violation of the Fourth Amendment, before they had obtained consent and in the absence of exigent circumstances; (2) that Rosario’s consent was invalid because the officers had coerced him into signing the written consent form; and (3) that their statements were the fruits of unlawful arrests made before Miranda rights were read.
C. The District Court’s Decision
The district court’s opinion of May 20, 1999 granted the suppression motions. The court first found that the officers had “reasonable suspicion entitling them to carry out an investigation of ... Apartment 1M” since
Rodriguez had seen Gori entering Apartment 1M ... and exiting the building thereafter in response to Mora’s telephone call, carrying a bag that turned out to be cocaine. A logical conclusion was that Gori could have a stash and that it could be in Apartment 1M.
Gori I, 1999 WL 322651, at *6 (internal quotation marks and citations omitted). The court credited the officers’ testimony and ruled that “specific, articulable facts existed to support a reasonable suspicion that evidence of criminal activity might exist in Apartment 1M.” Id. The court further found that Rosario consented to the officers’ entry, and then consented to their search of the apartment, and that both consents were voluntary. Id. at *9-*10.
The court concluded nevertheless that all of the evidence found in the apartment and all of the statements made by Rosario and Pichardo had to be suppressed on the ground that the officers’ oral directive that the apartment occupants step into the hallway constituted an unlawful seizure in violation of the Warrant Clause of the Fourth Amendment. See id. at *6-*9, *11. The court reasoned that the officers “seized the [49]*49occupants of Apartment 1M through a show of police authority and the issuance of orders to which the occupants submitted.” Id. at *7. The court went on to hold that the seizure was unconstitutional, because it was made pursuant to a warrant-less constructive entry into a home that did not fall into any of the exceptions to the warrant requirement. See id. at *7-*8.
The court’s Fourth Amendment analysis relied on the Supreme Court’s admonition in Payton v. New York, 445 U.S. 573, 588-90, 100 S.Ct. 1371, 63 L.Ed.2d 639 (1980), that police officers must obtain a warrant before physically entering a home in the course of making a felony arrest. The district court credited the officers’ testimony that they did not physically cross the threshold of Apartment 1M, see Gori I, 1999 WL 322651, at *8, but reasoned that their oral directive from outside constituted an “entry” into the apartment sufficient to implicate the Payton rule:
The defect in this case is thus not the absence of reasonable suspicion to conduct a Terry stop and an investigation, but the seizure of defendants Rosario and Pichardo by ordering them out of the apartment with guns drawn while they were inside Apartment 1M in violation of Payton. Reasonable suspicion might have supported a brief investigation of the occupants of Apartment 1M if they had been encountered outside the apartment. However, in this case, the use of force to compel the investigatory stop did not occur on the street but was directed at a private residence — a place entitled to special consideration under the Fourth Amendment. Here, Det. Rodriguez and Sgt. Contreras were not in possession of a warrant of any kind.... Thus, the seizure of the occupants of Apartment 1M violated the Fourth Amendment.
Id. at *8 (internal quotation marks and citations omitted).
The court concluded that the Payton violation tainted Rosario’s statements (that he was the owner of the apartment, that he knew Gori, and that Gori had paid him to hold a bag), Rosario’s two consents to search the apartment, and Pichardo’s statement that he knew the others were drug dealers. See id. at *9-*12. , Evidence bearing that taint was ordered suppressed. The government’s motion for reconsideration was denied. See Gori II, 1999 WL 816172, at *3.
DISCUSSION
“[W]hat the Constitution forbids is not all searches and seizures, but unreasonable searches and seizures.” Elkins v. United States, 364 U.S. 206, 222, 80 S.Ct. 1437, 4 L.Ed.2d 1669 (1960). It appears uncontested that the occupants of Apartment 1M, upon being ordered into the hallway, were “seized” within the meaning of the Fourth Amendment. A person can be seized without being physically restrained where “in view of all of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave.” United States v. Mendenhall, 446 U.S. 544, 554, 100 S.Ct. 1870, 64 L.Ed.2d 497 (1980) (plurality opinion of Stewart, J.); see also Terry v. Ohio, 392 U.S. 1, 19 n. 16, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968) (seizure occurs “when the officer, by means of physical force or show of authority, has in some way restrained the liberty of a citizen”). We agree with the district court that Det. Rodriguez and Sgt. Contreras seized the occupants of Apartment 1M through a show of police authority and the issuance of orders to which the occupants submitted. See United States v. Gomez, 633 F.2d 999, 1002, 1004 n. 6 (2d Cir.1980) (seizure occurs when police from fifteen feet away display their badge and shout “police” since “ ‘[a] reasonable person would have believed that he was not free to leave’ ” (quoting Mendenhall, 446 U.S. at 554, 100 S.Ct. 1870)).
Whether or not the seizure in this case violated the Fourth Amendment depends on whether or not — under all of the cir[50]*50cumstances — the officers’ order to evacuate Apartment 1M triggers the heightened protection offered by Payton against war-rantless entry into the home. If it does (as the district court found), then the order was unconstitutional unless the government can establish that one of the five exceptions to the warrant requirement apply to the facts of this case, a showing that the government does not undertake. See United States v. Restrepo, 890 F.Supp. 180, 205 (E.D.N.Y.1995) (delineating such exceptions for residential searches). But if Payton and the warrant requirement are not implicated (and we conclude that they are not), then the order to evacuate the apartment and the incidental seizure of its occupants were lawful so long as the officers acted reasonably under the totality of circumstances. See Terry, 392 U.S. at 20, 88 S.Ct. 1868 (noting that “an entire rubric of police conduct” is not subject to the warrant procedure but “[ijnstead ... must be tested by the Fourth Amendment’s general proscription against unreasonable searches and seizures ”) (emphasis added).
A. Payton and the Warrant Requirement
The Fourth Amendment’s warrant requirement protects one’s privacy interest in home or property. Absent exigent circumstances or some other exception, the police must obtain a warrant before they enter the home to conduct a search or otherwise intrude on an individual’s legitimate expectation of privacy. See Maryland v. Dyson, 527 U.S. 465, 466, 119 S.Ct. 2013, 144 L.Ed.2d 442 (1999) (per curiam) (“The Fourth Amendment generally requires police to secure a warrant before conducting a search.” (citing California v. Carney, 471 U.S. 386, 390-91, 105 S.Ct. 2066, 85 L.Ed.2d 406 (1985))).
Absent a reasonable expectation of privacy, however, the warrant requirement is inapplicable and the legitimacy of challenged police conduct is tested solely by the Fourth Amendment’s requirement that any search or seizure be reasonable. See Oliver v. United States, 466 U.S. 170, 177, 104 S.Ct. 1735, 80 L.Ed.2d 214 (1984) (“[T]he touchstone of [Fourth] Amendment analysis [is] the question whether a person has a ‘constitutionally protected reasonable expectation of privacy.’ ” (quoting Katz v. United States, 389 U.S. 347, 360, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967) (Harlan, J., concurring))); Illinois v. Andreas, 463 U.S. 765, 771, 103 S.Ct. 3319, 77 L.Ed.2d 1003 (1983) (“The Fourth Amendment protects legitimate expectations of privacy rather than simply places. If the inspection by police does not intrude upon a legitimate expectation of privacy, there is no ‘search’ subject to the Warrant Clause.”).
No reasonable expectation of privacy inheres in what is left “ ‘visible to the naked eye.’ ” Florida v. Riley, 488 U.S. 445, 450, 109 S.Ct. 693, 102 L.Ed.2d 835 (1989) (quoting California v. Ciraolo, 476 U.S. 207, 215, 106 S.Ct. 1809, 90 L.Ed.2d 210 (1986)). Thus the Fourth Amendment does not require a police officer to obtain a warrant before making a felony arrest in a public place, see United States v. Watson, 423 U.S. 411, 418 n. 6, 96 S.Ct. 820, 46 L.Ed.2d 598 (1976); or seizing an item in plain view if there is cause to believe that it is evidence of crime, see Arizona v. Hicks, 480 U.S. 321, 326, 107 S.Ct. 1149, 94 L.Ed.2d 347 (1987); or conducting surveillance of a fenced backyard from a plane 1000 feet above, see Ciraolo, 476 U.S. at 213-15, 106 S.Ct. 1809. “[T]he threshold question” in this case is therefore whether the defendants exhibited a “legitimate expectation of privacy” when they were ordered out of their apartment. United States v. Smith, 621 F.2d 483, 486 (2d Cir.1980); accord Bond v. United States, 529 U.S. 334, 120 S.Ct. 1462, 1465, 146 L.Ed.2d 365 (2000) (“First, we ask whether the individual, by his conduct, has exhibited an actual expectation of privacy; that is, whether he has shown that ‘he [sought] to preserve [something] as private.’ ” (quoting Smith v. Maryland, 442 U.S. 735, 740, 99 S.Ct. 2577, 61 L.Ed.2d 220 (1979))); [51]*51United States v. Pena, 961 F.2d 333, 337 (2d Cir.1992).
Fourth Amendment privacy interests are most secure when an individual is at home with doors closed and curtains drawn tight. Thus “searches and seizures inside a home without a warrant are presumptively unreasonable.” Payton, 445 U.S. at 586, 100 S.Ct. 1371; see id. at 576, 100 S.Ct. 1371 (prohibiting “the police from making a warrantless and nonconsensual entry into a suspect’s home in order to make a routine felony arrest”). The Payton rule, upon which the district court relied, is directed primarily at warrantless physical intrusion into the home. See id. at 585-86, 100 S.Ct. 1371 (“[PJhysical entry of the home is the chief evil against which the wording of the Fourth Amendment is directed.” (internal quotation marks and citation omitted)); id. at 590, 100 S.Ct. 1371 (“[T]he Fourth Amendment has drawn a firm line at the entrance to the house. Absent exigent circumstances, that threshold may not be crossed without a warrant.”); id. at 589, 100 S.Ct. 1371 (“In none is the zone of privacy more clearly defined than when bounded by the unambiguous physical dimensions of an individual’s home[.]”); New York v. Harris, 495 U.S. 14, 17, 110 S.Ct. 1640, 109 L.Ed.2d 13 (1990) (“Payton was designed to protect the physical integrity of the home[.]”). It is unclear whether Payton’s, solicitude is aroused when a dwelling is penetrated by the voice of a police officer standing outside. Compare United States v. Carrion, 809 F.2d 1120, 1128 (5th Cir.1987) (finding Payton inapplicable where “arrest was effected before the agents entered [the defendant’s] hotel room”), with United States v. Morgan, 743 F.2d 1158, 1166 (6th Cir. 1984) (warrant required before police can use coercion to draw suspect out of home regardless of whether police enter), and United States v. Johnson, 626 F.2d 753, 757 (9th Cir.1980) (warrant required where suspect opens door to officers who misrepresent their identities).
The facts of this case, however, do not draw us into that debate.2 Payton does not hold or suggest that the home is a sanctuary from reasonable police investigation. See, e.g., Silverman v. United States, 365 U.S. 505, 511, 81 S.Ct. 679, 5 L.Ed.2d 734 (1961) (“At the very core [of the Fourth Amendment] stands the right of a man to retreat into his own home and there be free from unreasonable government intrusion.” (emphasis added)); United States v. Lovelock, 170 F.3d 339, 343-44 (2d Cir.1999) (“What a citizen is ‘assured by the Fourth Amendment ... is not that no government search of his house will occur’ in the absence of a warrant ... ‘but that no such search will occur that is unreasonable.’ ” (quoting Illinois v. Rodriguez, 497 U.S. 177, 183, 110 S.Ct. 2793, 111 L.Ed.2d 148 (1990) (first alteration in original) (additional internal quotation marks omitted))); United States v. Holland, 755 F.2d 253, 255 (2d Cir.1985) (“[Payton ] recognized the existence of a limited right of privacy against an arrest in the suspect’s home[.]” (emphasis added)). Like any thread of Fourth Amendment jurisprudence, Payton protects an individual’s privacy interest; thus, “[w]hat a person knowingly exposes to the public, even in his own house or office, is not a subject of Fourth Amendment protection.” United States v. Santana, 427 U.S. 38, 42, 96 S.Ct. 2406, 49 L.Ed.2d 300 (1976) (emphasis added) (quoting Katz, 389 U.S. at 351, 88 S.Ct. 507 (internal quotation marks omitted)); see also United States v. Fields, 113 F.3d 313, 321-22 (2d Cir.1997) (where blinds are raised, police are entitled to peer through [52]*52back window of home since “what a person chooses voluntarily to expose to public view thereby loses its Fourth Amendment protection”). The dissent characterizes our position as holding that the opening of the door to a home transforms the entire home into a public place. This generalizes the holding and reach of the opinion beyond its scope or ambition. The facts critical to the analysis are that the interior of Apartment 1M was exposed to public view when the door was voluntarily opened. And the principle that governs those facts is found in United States v. Santana, not Payton.
In Santana, police officers went to a known stash house to arrest a suspect who had earlier sold drugs to an undercover officer. The police were fifteen feet from the house when they saw the suspect standing in the doorway. They displayed their identification and shouted “police.” See Santana, 427 U.S. at 40, 96 S.Ct. 2406. The suspect retreated into the vestibule of her house, the officers followed her through the open door, and she was arrested after a scuffle.3 The Supreme Court ruled that the warrantless arrest did not violate the heightened Fourth Amendment protections of Payton, because a suspect exposed to public view through an open doorway, even at home, cannot claim a protected privacy interest that triggers the warrant requirement:
While it may be true that under the common law of property the threshold of one’s dwelling is “private,” ... it is nonetheless clear that under the cases interpreting the Fourth Amendment Santana was in a “public” place. She was not in an area where she had any expectation of privacy. “What a person knowingly exposes to the public, even in his own house or office, is not a subject of Fourth Amendment protection.”
Id. at 42, 96 S.Ct. 2406 (quoting Katz, 389 U.S. at 351, 88 S.Ct. 507). A suspect in her open doorway becomes “as exposed to public view, speech, hearing, and touch as if she had been standing completely outside her house.” Id. This analogy is adaptable to the facts here, because when the defendants voluntarily opened the door of Apartment 1M in response to a knock from the delivery person whom they invited, they created a vista from a public place or common area. Cf. Riley, 488 U.S. at 449, 109 S.Ct. 693 (“[T]he police may see what may be seen from a public vantage point....” (internal quotation marks omitted)); Fields, 113 F.3d at 321 (“[T]he police are free to observe whatever may be seen from a place where they are entitled to be” and “what a person chooses voluntarily to expose to public view thereby loses its Fourth Amendment protection.”).
Courts applying Santana confirm that conclusion. See United States v. Vaneaton, 49 F.3d 1423, 1425, 1427 (9th Cir.1995) (Payton not violated by warrantless arrest at door of motel room where suspect opened door after viewing uniformed officers knocking at his door, officers “ha[d] not used coercion, and the suspect acquiesce[d] to the encounter”); United States v. Berkowitz, 927 F.2d 1376, 1387 (7th Cir.1991) (warrantless arrest of suspect who opened door in response to agent’s knock not violate Payton when person “recognizes and submits to that authority”); Carrion, 809 F.2d at 1128 (Payton not violated by warrantless arrest of suspect standing in open doorway of hotel room); United States v. Herring, 582 F.2d 535, 543 (10th Cir.1978) (no expectation of privacy where defendant opens door in response to officer’s knock).4
[53]*53Applying the Santana principle, we hold that the warrant requirement and the heightened protections established for the home in Payton are not implicated here: Once the apartment was opened to public view by the defendants in response to the knock of an invitee, there was no expectation of privacy as to what could be seen from the hall. The officers therefore needed no warrant to temporarily “seize” the occupants and conduct a limited investigation, and such an investigation is constitutional so long as it was reasonable in all the circumstances.5
The defendants argue that (1) Santana is limited to situations where police have probable cause to arrest a suspect standing in plain view and does not extend to situations where police have only a reasonable suspicion that criminal activity is afoot; (2) the warrantless arrest of Santana did not implicate Payton because Santana was standing at the threshold of a doorway rather than inside; and (3) this court’s holding in United States v. Crespo, 834 F.2d 267 (2d Cir.1987) disapproves the government’s interpretation of Santana. We reject these arguments.
First, as discussed below in some detail, it is undisputed that officers Rodriguez and Contreras had “ ‘reasonable suspicion’ entitling them to carry out an investigation of where Gori obtained the cocaine by questioning the occupants of Apartment 1M.” Gori I, 1999 WL 322651, at *6; see, e.g., United States v. Bold, 19 F.3d 99, 102 (2d Cir.1994) (“A police officer may, in appropriate circumstances and in an appropriate manner, stop a person for purposes of investigating possibly criminal behavior, even though there is no probable cause to make an arrest.”). The defendants argue that reasonable suspicion is not enough because the Santana exception to Payton is limited to circumstances in which officers have probable cause to arrest a suspect exposed to public view. We see no basis for that limitation. The Santana analysis, which supports the war-rantless arrest of a suspect who has no legitimate expectation of privacy, a foHiori allows the lesser intrusion of a brief investigatory detention. See Illinois v. Wardlow, 528 U.S. 119, 120 S.Ct. 673, 677, 145 L.Ed.2d 570 (2000) (investigatory detention “is a far more minimal intrusion” than arrest); United States v. Place, 462 U.S. 696, 705, 103 S.Ct. 2637, 77 L.Ed.2d 110 (1983) (same).
Next, defendants contend that Santana is purely a doorway case, and has no bearing on whether a person sitting on a couch at the far end of an exposed room enjoys a protectible privacy interest. But the prin[54]*54ciple of Santana, as confirmed in the.circuit cases that apply.it, is that the warrant requirement depends on the suspect’s actual expectation of privacy. No one in a place opened to public view can expect privacy in that place and at that time, whether the suspect is on the threshold, in a vestibule or at the far end of an exposed interior room. Once a door is voluntarily opened by an occupant in response to a knock by someone invited by an occupant, the Fourth Amendment’s protection of the home is not abrogated so long as the officer’s conduct was reasonable under the circumstances.
Santana says that the suspect in that case was “standing directly in the doorway — one step forward would have put her outside, one step backward would have put her in the vestibule of her residence.” 427 U.S. at 40 n. 1, 96 S.Ct. 2406. We read this passage as descriptive, not as the formulation of a rule under the Fourth Amendment. The Court elsewhere has warned against employing “metaphysical subtleties” to resolve Fourth Amendment challenges, see Frazier v. Cupp, 394 U.S. 731, 740, 89 S.Ct. 1420, 22 L.Ed.2d 684 (1969), and we therefore doubt that it is appropriate to resolve a Payton challenge on the basis of a suspect’s placement within a visible scene. The idea that Santana turns on the defendant’s location is, according to Professor LaFave, “unsound from the standpoint of both principle and pragmatism,” because “even if courts could be expected to sort out the ‘in’-‘at’ and W-‘by’ distinctions on a regular basis, one cannot help but wonder why that burden should be imposed upon them.” 3 Search and Seizure § 6.1(e), at 256-57 (citing Duncan v. Storie, 869 F.2d 1100, 1102 (8th Cir.1989) (admonishing that it is “unwise to become preoccupied with the exact location of the individual in relation to the doorway”)). A person who opens the door to a dwelling in response to a knock by an invitee opens to view whatever can be seen by a nosy neighbor or an observant police officer. Those inside exhibit no actual expectation of privacy and therefore lose the heightened constitutional protection that might flow from such an expectation.
United States v. Crespo, 834 F.2d 267 (2d Cir.1987), is not to the contrary. There, we said in dictum that Santana would not apply if the door was opened in response to an informer’s knock, if “the door to the apartment was at most half-opened, and ... [if] that degree of exposure was induced by [officers] who were seeking to flush [the suspect] out.” Id. at 270. The facts of Crespo were that a visible “display of weapons, together with the [federal] agents’ kicking the door, caused the door to be opened by threat of force and not with consent.” Id. at 269. Remotely similar facts are not presented in this appeal and we reject any analogy to the facts of Crespo or (for that matter) its embedded hypotheticals.
B. Fourth Amendment Reasonableness
Once it is decided that no warrant was needed, “the central inquiry” under the Fourth Amendment becomes “reasonableness in all the circumstances.” Terry, 392 U.S. at 19, 88 S.Ct. 1868. “ ‘[T]he touchstone of our analysis under the Fourth Amendment is always the reasonableness in all the circumstances of the particular governmental invasion of a citizen’s personal security,’ ” and “reasonableness ‘depends on a balance between the public interest and the individual’s right to personal security free from arbitrary interference by law officers.’ ” Maryland v. Wilson, 519 U.S. ,408, 411, 117 S.Ct. 882, 137 L.Ed.2d 41 (1997) (quoting Pennsylvania v. Mimms, 434 U.S. 106, 108-09, 98 S.Ct. 330, 54 L.Ed.2d 331 (1977) (per curiam) (additional internal quotation marks omitted)).
We conclude that officers Rodriguez and Contreras acted reasonably at every stage of the “swiftly developing situation” presented on this record. United States v. Sharpe, 470 U.S. 675, 686, 105 S.Ct. 1568, 84 L.Ed.2d 605 (1985) (in as[55]*55sessing reasonableness under Terry, courts “should take care to consider whether the police are acting in a swiftly developing situation, and in such cases the court should not indulge in unrealistic second-guessing”). Based on the exigencies of the moment — one following the other— what the police did, said and asked at each stage of the encounter was reasonable from a Fourth Amendment perspective. The police had no obvious option, given the circumstances, other than to proceed as they did.6
The district court found that Det. Rodriguez and Sgt. Contreras had reasonable suspicion that Apartment 1M was being used as a “stash” for narcotics and that the occupants of the apartment might be involved in narcotics trafficking. See Gori I, 1999 WL 322651, at *6. We agree. See United States v. Martinez-Gonzalez, 686 F.2d 93, 99 (2d Cir.1982) (“[I]nformation the agents had when they placed apartment 7F under surveillance created strong suspicions based on their experience that 7F was being used as a ‘stash pad’ for drugs ... and therefore justified them in detaining for purposes of a Terry stop any persons seen entering or exiting.” (internal quotation marks and citations omitted)).
The encounter at the door of Apartment 1M was precipitated by the arrival of the food delivery ordered by the occupants. The situation reasonably called for some immediate measures, and we conclude that accompanying the delivery woman to the door was a reasonable course of action in the circumstances, if not the only or necessary one. If they let the delivery woman proceed unaccompanied after seeing police in the foyer, she might betray their presence intentionally or by her alarm; if they turned her away, the hungry occupants might have called the take-out restaurant to complain about the delay, and been alerted that way. The police could assume that once alerted, the occupants might have disposed of the contraband by the window or the toilet, or might have precipitated violence. Cf. Michigan v. Summers, 452 U.S. 692, 702-03, 101 S.Ct. 2587, 69 L.Ed.2d 340 (1981) (recognizing that police presence “may give rise to sudden violence or frantic efforts to conceal or destroy evidence”); United States v. Medina, 944 F.2d 60, 68-69 (2d Cir.1991) (warrantless arrest and entry proper “to prevent the destruction or moving of the evidence” because of non-return of arrested accomplice in drug conspiracy); United States v. Clement, 854 F.2d 1116, 1119-20 (8th Cir.1988) (reasonable for officers to believe that non-return of the defendant’s associates would warn defendant that drug sale had failed and would prompt defendant to destroy evidence).
One salient defect of the dissent is its failure to prescribe what the police should have done within the proper parameters of the Constitution. The reasonableness under the Fourth Amendment of any Terry stop is by definition fact-specific. See Terry, 392 U.S. at 21-22, 88 S.Ct. 1868 (making reasonableness determination requires assessing facts available to officer at the moment of search or seizure). Under the facts presented on this appeal, the constitutional principles urged by the dissent would offer the police the options of (i) risking disclosure of their surveillance position with concomitant dangers, such as violent confrontation and destruction of evidence, or (ii) risking their lives, the lives of the apartment inmates (including a child) or the life of the delivery person.
Under the circumstances, it was reasonable for the officers to flank the delivery person when she knocked. And when the door was opened, and the occupants and the police could see each other, it was reasonable for the police to ask the occupants of a known narcotics stash house to step outside for the purposes of a limited investigation: otherwise, the officers would [56]*56have been exposed to danger.7 See id. at 24, 88 S.Ct. 1868 (in the course of investigatory detention “it would appear to be clearly unreasonable to deny the officer the power to take necessary measures to ... neutralize the threat of physical harm”); United States v. Becerra, 97 F.3d 669, 671-72 (2d Cir.1996) (reasonable to suspect that “drug dealers commonly keep firearms on then- premises as tools of the drug trade”) (citations and internal quotation marks omitted); see also United States v. Alexander, 907 F.2d 269, 272 (2d Cir.1990) (“A law enforcement agent, faced with the possibility of danger, has a right to take reasonable steps to protect himself ... regardless of whether probable cause to arrest exists.”).
Terry confirms that an investigatory stop entails “more than the governmental interest in investigating crime”; there is also the “more immediate interest” of “the neutralization of danger to the policeman in the investigative circumstance.” 392 U.S. at 23, 26, 88 S.Ct. 1868. For this reason, it is well established that officers may ask (or force) a suspect to move as part of a lawful Tory stop. See Halvorsen v. Baird, 146 F.3d 680, 684-85 (9th Cir.1998) (officers handcuffed suspect and drove him to a nearby gas station for questioning); United States v. Maher, 145 F.3d 907, 908-09 (7th Cir.1998) (police moved a suspect from his home to his front yard in order to do a pat-down); United States v. Vega, 72 F.3d 507, 515 (7th Cir. 1995) (police asked suspect to return to site of possible narcotics transaction); United States v. Blackman, 66 F.3d 1572, 1576-77 (11th Cir.1995) (FBI agents surrounded apartment, ordered suspects to come out with hands up, and handcuffed them); United States v. Tehrani, 49 F.3d 54, 61-62 (2d Cir.1995) (traveler taken to small, private office). The officers acted reasonably under the circumstances to assure their own safety, the safety of the person delivering the food, and the safety of the occupants (one of them a child).
In terms of danger to the police and others, there is no appreciable difference between (i) a typical Terry encounter between officers and suspects that might occur in the hallway of an apartment building and (ii)' the situation here, in which police standing in the hallway come face to face with the suspects through a door opened voluntarily by the suspects in response to a knock by an invitee. Because there is no principled basis for requiring probable cause and a warrant in the latter case but not the former, Tory must encompass this type of encounter and the police should have the authority to briefly question and frisk the suspects.
Finally, the investigative methods employed once the occupants were in the hallway were no more intrusive than the situation reasonably justified. Investigative methods reasonable under Terry are those “necessary to effectuate the purpose of the stop ... [and] should be the least intrusive means reasonably available to verify or dispel the officer’s suspicion in a short period of time.” Florida v. Royer, 460 U.S. 491, 500-01, 103 S.Ct. 1319, 75 L.Ed.2d 229 (1983); id. at 500, 103 S.Ct. 1319 (“The scope of the intrusion permitted will vary to some extent with the particular facts and circumstances of each case.”). The purpose of the stop in this case was to verify or dispel the suspicion that Apartment 1M was being used as a stash house for narcotics and that one or more of the occupants might be involved [57]*57in the trafficking. Soon after the occupants were collected in the hallway, Det. Rodriguez asked two questions: who owned the apartment, and whether the owner knew Gori. Rosario immediately identified himself as the owner, privately disclosed to Rodriguez that Gori had paid him $1,000 “to hold a bag,” and gave (and perhaps volunteered) consent to a search of the apartment before leading Det. Rodriguez to the armóme. We are unable to identify any unreasonable conduct on the part of Det. Rodriguez. “[T]he right to interrogate during a ‘stop’ is the essence of Temj and its progeny.” United States v. Oates, 560 F.2d 45, 63 (2d Cir.1977); see also Summers, 452 U.S. at 700 n. 12, 101 S.Ct. 2587 (interrogation is “‘the most common’ ” of “ ‘several investigative techniques which may be utilized effectively in the course of a Terry-type stop’ ” (quoting 3 Wayne R. LaFave, Search and Seizure § 9.2, at pp. 36-37 (1978))), and there is no evidence that Rosario’s answers were “obtained by threat or in any way other than by voluntary consent.” Gori I, 1999 WL 322651, at *9-*10. Det. Rodriguez’s questions served the purpose of readily confirming or dispelling a reasonable suspicion, involved no more intrusion than necessary to accomplish the purposes of his investigation, and thereby fit comfortably within the limits authorized by Terry, 392 U.S. at 20-26, 88 S.Ct. 1868.
:¡: * * * * *
For these reasons, we conclude that the officers’ conduct involved no more intrusion than necessary under a rapidly developing situation, and therefore satisfies the standard of “reasonableness in all the circumstances of the particular governmental invasion.” Terry, 392 U.S. at 19, 88 S.Ct. 1868. The evidence seized and statements made in the course of that investigation therefore are not suppressible as tainted fruits of an illegal search or seizure in violation of the Fourth Amendment. The judgment of the district court on this ground is reversed.
CONCLUSION
The district court’s order suppressing evidence under the Fourth Amendment is reversed.
