OPINION IN No. 86-3068.

Leslie Craig Robertson and Connie M. Steeprow appeal rulings on suppression of evidence. Robertson had stipulated that the evidence was sufficient to show that he had manufactured methamphetamine on a residence located at 855 68th Street, Springfield, Oregon and Steeprow had stipulated that the evidence was sufficient to show she attempted to manufacture methamphetamine at the same address. The stipulations are void if the motions to suppress are reversed on appeal. We affirm the district court as to Robertson, reverse as to Steeprow.

On October 16, 1985, at about 1:45 P.M., Richard W. Wisenor, an agent of the Drug Enforcement Agency (DEA), in Eugene, Oregon learned from an anonymous telephone call that Lyle Johnson was operating “a crank lab” at 855 68th Street, Springfield, Oregon, where the informant said Johnson lived. Wisenor, a veteran of 14 years with the DEA, knew that “a crank lab” was a manufactory of methamphetamine. His informant told him that she had visited the lab that morning and that it had been in operation with Johnson and two associates present.

Wisenor learned from the Springfield Utilities Board that Johnson was indeed a customer listed at 855 68th Street. He himself knew that Johnson had prior arrests for manufacturing methamphetamine in Lane City, Oregon. He now learned from state police of an outstanding Oregon arrest warrant against Johnson for this crime. The warrant, issued March 15, 1985, was, according to the county clerk, still valid. Driving to Springfield, Wisenor and a state police officer inspected the house at 855 68th Street from the outside and noted that the house windows were curtained and the garage windows were masked. They also observed by the house a black pick-up truck that turned out to be registered to a person with a prior drug record.

*779 At about 4:30 P.M. of the same day, Wisenor accompanied by seven other police officers — Springfield Police, Oregon State Police, and DEA agents — arrived to arrest Johnson on the state warrant. They saw two persons — a woman, later identified as Steeprow, leaving the house on the walkway; a man, later determined to be Johnson, in the doorway. When the man saw the uniformed officers, he stepped inside, slammed the door and bolted it. The agents told the woman to freeze and displayed guns. The police then ordered the man to open the door and when nothing happened they forced it open. They found Johnson hiding under a foam rubber pad in the kitchen. Johnson told the police he had been “cooking” all day and felt sick. Wise-nor noted equipment characteristic of a crank lab and sniffed such a laboratory’s characteristic odor.

Shortly after the entry, Wisenor told Steeprow that she was free to go if she would leave her backpack and purse behind. She refused to leave them behind and therefore remained. Wisenor wrote out by hand a 7-page affidavit detailing the day’s events. Some three hours later a warrant was issued by Magistrate Michael Hogan on the basis of Wisenor’s affidavit.

With the warrant secured, the agents searched the house and Steeprow’s backpack. Steeprow’s and Robertson’s fingerprints were found on the laboratory equipment. Formulas for making methamphetamine were found, in her handwriting, in Steeprow’s backpack.

Johnson killed himself in prison. Robertson and Steeprow were indicted and moved to suppress the evidence. After a hearing, Magistrate Hogan made findings of fact and recommended denial of their motions. After a further hearing, District Judge James Burns denied them. Robertson was convicted of manufacturing methamphetamine in violation of 21 U.S.C. § 841 (a)(1) and 18 U.S.C. § 2 and was sentenced to fifteen years in prison with a five year special parole term. Steeprow was convicted of attempting to manufacture methamphetamine in violation of 21 U.S.C. §§ 841 (a)(1) and 846 and 18 U.S.C. § 2 and was sentenced to five years in prison. Each appealed. Their appeals have been consolidated for argument and decision.

A

Robertson argues that the seven-month delay in execution of the arrest warrant for Johnson was unconstitutional, violating the rights of “the individual” under the Fourth Amendment, the Due Process and Equal Protection Clauses of the Fourteenth Amendment, and comparable Oregon constitutional and statutory provisions. He claims that the warrant should have been executed during a routine traffic stop of Johnson months earlier.

Robertson encounters a fundamental obstacle: standing. A defendant must show standing even if the government has not pressed the issue in the district court. United States v. Nadler, 698 F.2d 995, 998 (9th Cir.1983). Fourth Amendment rights are personal rights which may not be vicariously asserted. Rakas v. Illinois, 439 U.S. 128, 133-34 , 99 S.Ct. 421, 425-26 , 58 L.Ed.2d 387 (1978). Even when officers make a blatantly pretextual arrest of one defendant that creates exigent circumstances justifying search of a second defendant’s house, the second defendant may not challenge the legality of the arrest. United States v. Chase, 692 F.2d 69, 70 (9th Cir.1982). Here it is undisputed that the arrest warrant named only Johnson. Had he survived, he could have raised a challenge to the delay in execution of the warrant. Standing in for the dead man, Robertson may not invoke any rights Johnson might have had.

As to the alleged violations of state law, the evidence would be admissible in any case, United States v. Kovac, 795 F.2d 1509, 1511 (9th Cir.1986), cert. denied, — U.S. —, 107 S.Ct. 951 , 93 L.Ed.2d 1000 (1987). If Oregon law were relevant, Robertson lacked standing. State v. Emery, 41 Or.App. 35 , 597 P.2d 375 (1979).

*780 B

Robertson relies upon the district court’s finding that he lived at the house to argue that his expectation of privacy was violated by execution of the arrest warrant for Johnson without a search warrant. Robertson, however, at most shared the residence with Johnson, who held the lease and paid the rent and utilities. As it was lawful for the police to enter to arrest Johnson, their entry was not excludable as a violation of any expectation of privacy on the part of Robertson. United States v. Ramirez, 770 F.2d 1458, 1460 (9th Cir.1985). Johnson was not Robertson’s guest. See Steagald v. United States, 451 U.S. 204, 213 , 101 S.Ct. 1642, 1648 , 68 L.Ed.2d 38 (1981). Johnson was as much a resident as Robertson and so his residence could be entered with a warrant for his arrest. Payton v. New York, 445 U.S. 573, 590 , 100 S.Ct. 1371, 1382 , 63 L.Ed.2d 639 (1980); Ramirez, supra; United States v. Underwood, 717 F.2d 482 (9th Cir.1983) (en banc), cert. denied, 465 U.S. 1036 , 104 S.Ct. 1309 , 79 L.Ed.2d 707 (1984). Robertson’s motion to suppress fails.

The judgment as to Robertson is AFFIRMED.

OPINION IN No. 86-3074.

In Steeprow’s appeal, the facts are as set forth in United States v. Robertson, No. 86-3068. Steeprow challenges her detention and the subsequent search of her back pack.

I

Steeprow’s Detention:

Steeprow objects to her detention, contending that it was not a Terry stop, but an arrest for which probable cause was lacking. We agree with this contention.

A

Whether an arrest has occurred depends on all the surrounding circumstances, including the extent to which liberty of movement is curtailed and the type of force or authority employed. See United States v. Patterson, 648 F.2d 625, 632 (9th Cir.1981) (citing United States v. Harrington, 636 F.2d 1182, 1186 (9th Cir.1981) (citations omitted)). We often confront the issue of when a legitimate “Terry stop,” for which only reasonable suspicion of criminal activity is required, escalates into an arrest for which probable cause is required. The differing standards for each reflect the differing degrees of intrusion characteristic to each. A Terry stop involves no more than a brief stop, interrogation and, under the proper circumstances, a brief check for weapons. Beyond such a brief and narrowly circumscribed intrusion, an arrest occurs, for which probable cause is required. See Kraus v. City of Pierce, 793 F.2d 1105, 1108-09 (9th Cir.1986), cert. denied, — U.S. —, 107 S.Ct. 1571 , 94 L.Ed.2d 763 (1987). The ultimate question is whether, in view of all the circumstances, a reasonable person would believe himself to be under arrest. Id. In Kraus , we examined the turning of spotlights on defendants, along with the confrontation of them by officers with weapons drawn. Defendants were ordered to raise their arms and drop to their knees. We held that, under these circumstances, a reasonable person would believe himself to be under arrest. 793 F.2d at 1109 . Previously, in United States v. Strickler, 490 F.2d 378 (9th Cir.1974), we had held that, where police cars surrounded a vehicle occupied by the defendant and pointed their guns at him, an arrest and not a mere investigatory detention had occurred, and thus could be justified only if probable cause existed. Id. at 379 . We reasoned that, while at gunpoint, the restriction of defendant’s liberty of movement was complete. In Strickler , we could discern no difference in terms of restriction of liberty between holding defendant at gunpoint and handcuffing him and pronouncing him to be under arrest. Similarly, in United States v. Ramos-Zaragosa, 516 F.2d 141, 144 (9th Cir.1975), we held that the holding of defendants at gunpoint under circumstances not suggesting fears for their personal safety, amounted to an arrest for purposes of the Fourth Amendment.

*781 We conclude that the officers’ detention of Steeprow at gunpoint was an arrest which required probable cause. Steeprow was confronted by seven to ten police officers, one of whom aimed his gun at her nose, told her to freeze, and detained her for at least five and perhaps fifteen minutes. The restriction of her liberty of movement was complete upon this encirclement by officers who gave her orders at gunpoint. See Kraus, 793 F.2d at 1108-09 (encirclement of defendants by officers with guns drawn; spotlight); United States v. Coades, 549 F.2d 1303, 1305 (9th Cir.1977) (ordering defendant to stop and prostrate self at gunpoint constituted arrest); Ramos-Zaragosa, supra at 144 (holding defendants at gunpoint); Strickler, 490 F.2d at 380 (surrounding defendant in car with police cruisers, holding at gunpoint) (citing Henry v. United States, 361 U.S. 98 , 80 S.Ct. 168 , 4 L.Ed.2d 134 (1959)). Steeprow was not free to “choose between terminating or continuing the encounter.” See United States v. Johnson, 626 F.2d 753, 755 (9th Cir.1980), aff'd, 457 U.S. 537 , 102 S.Ct. 2579 , 73 L.Ed.2d 202 (1982). We acknowledge previous holdings that such a complete restriction, if brief and not excessive under the circumstances, may constitute a valid “Terry stop” and not an arrest. See, e.g., United States v. Bautista, 684 F.2d 1286, 1289 (9th Cir.1982), cert. denied, 459 U.S. 1211 , 103 S.Ct. 1206 , 75 L.Ed.2d 447 (1983); Patterson, 648 F.2d at 632-34 . But such is not the case here given the excessive nature of the restriction under the circumstances. Steeprow was not armed, but the officers made no attempt to discern if she was armed, thereby strongly suggesting that they had not the slightest indication that she was armed. Compare United States v. Greene, 783 F.2d 1364, 1368 (9th Cir.) (police knew defendants armed, frisked them), cert. denied, 476 U.S. 1185 , 106 S.Ct. 2923 , 91 L.Ed.2d 551 (1986). Nothing in the record suggests that the display of force was necessary to ensure her compliance with a request to stop. Compare Patterson, 648 F.2d at 633-34 (defendant in driver’s seat with motor running at scene of arrest of other defendant); Bautista, 684 F.2d at 1289 (defendant kept pacing, turning head, “as if he was thinking about running”). See United States v. Thompson, 558 F.2d 522, 524 (9th Cir.1977), ce rt. denied, 435 U.S. 914 , 98 S.Ct. 1466 , 55 L.Ed.2d 504 (1978). Accordingly, the purpose of the asserted “Terry stop”— to allow the officers to investigate without fear of flight or violence, see Adams v. Williams, 407 U.S. 143 , 92 S.Ct. 1921 , 32 L.Ed.2d 612 (1972)—was not served by the intrusion imposed. No necessity, reason nor purpose is shown for stopping Steep-row in order to serve the arrest warrant on Johnson.

We do not find the recently decided case of Greene persuasive as to the dissent’s contention that a mere “Terry stop” occurred. The dissent reasons that, in this case, as in Greene, 783 F.2d at 1367-68 , such use of force does not constitute an arrest where the circumstances justify the agents’ fears for their personal safety. 1 *782 See also Coades, supra. While recognizing that the officers had no specific information that Steeprow was armed and dangerous, the dissent nevertheless declares that “sudden violence could reasonably be anticipated.” The dissent distinguishes Strickler and Ramos-Zaragosa on the basis that those cases “involved stops of suspected vehicles by police pointing guns from their adjacent cars.” The dissent suggests that Greene is the more vital authority and has supplanted Strickler and Ramos-Zaragosa . 2

The ground for our holding in Greene was that the officers in that case had specific knowledge that the defendants were armed. See 783 F.2d at 1368 . On this basis, the Court upheld the officers’ stop of defendants as a legitimate Terry stop. Id. In other words, in Greene , officers were confronted with circumstances justifying fears for personal safety — although not amounting to probable cause so as to justify an arrest — which justified the temporary restriction of defendant’s freedom of movement. See also United States v. Taylor, 716 F.2d 701, 708 (9th Cir.1983) (police knew defendant armed and dangerous); Coades, supra (police knew defendants armed and in flight from bank robbery attempt and gun fight). Here, there is no indication that the officers were confronted with circumstances such as those in Greene, Taylor, and Coades . Certainly the slamming of the door provided cause for belief that violence might erupt in the house. But, unlike in Greene, Taylor, and Coades , the record in the case at bench is bare of any indication that Steeprow was armed or dangerous. Underscoring this fact is the officers’ omission to engage in a patdown or frisk in order to search for weapons. The officers in Greene conducted such a frisk, manifesting their fears of physical danger. See 783 F.2d at 1367 . See also Taylor, 716 F.2d at 708 ; Coades, 549 F.2d at 1305 .

B.

Having held that the detention at gunpoint of Steeprow amounted to an arrest, the next question is whether probable cause existed for that arrest as required by the Fourth Amendment.

We hold that probable cause for her arrest was absent. For all that was then known to the officers, Steeprow was an innocent visitor. Lacking from both the arrest warrant for Johnson and the search warrant for the premises was the slightest indication that Steeprow was involved in criminal activity. Her mere presence on the premises, without more, cannot support an arrest of her under these circumstances. Compare Michigan v. Summers, 452 U.S. 692, 701 , 101 S.Ct. 2587, 2593 , 69 L.Ed.2d 340 (1981) (warrant justifying search of defendant’s house justified detention of his person on premises), Greene, 783 F.2d at 1368 (pistol in defendants' motel room), cert. denied, 476 U.S. 1185 , 106 S.Ct. 2923 , 91 L.Ed.2d 551 (1986), Taylor, supra (police knew defendants armed and dangerous), United States v. Patterson, 648 F.2d 625, 628 (9th Cir.1981) (defendant in car with engine running; officers knew gun under front seat), and Coades, supra (police knew defendants armed and in flight from bank robbery attempt and gun fight), *783 with Strickler, 490 F.2d at 380 (mere proximity to a residence where cocaine was being delivered and participation in some ambiguous driving and observing activity) and Ramos-Zaragosa, 516 F.2d at 144 (conformity of vehicle with imprecise description of informant, where informant’s reliability not demonstrated, did not justify arrest). See also Sibron v. New York, 392 U.S. 40, 62-63 , 88 S.Ct. 1889, 1902-03 , 20 L.Ed.2d 917 (1968) (talking to a number of known narcotics addicts over a period of eight hours insufficient to establish probable cause to arrest); Kraus, 793 F.2d at 1109 (seeing rapidly departing car from parking lot after robber seen fleeing on foot into parking lot insufficient to establish probable cause for arrest of car owners). It is undisputed that the officers had probable cause to believe that criminal activity was afoot in the house. But where the standard for the seizure of a person is probable cause, that seizure must be supported by probable cause particularized with respect to that person. Ybarra v. Illinois, 444 U.S. 85 , 93 & n. 4, 100 S.Ct. 338 , 343 & n. 4, 62 L.Ed.2d 238 (1979) (warrant to search a place cannot be construed to authorize a search of every individual in that place). It is insufficient to point to the defendant’s mere proximity to others independently suspected of criminal activity. See Ybarra, 444 U.S. at 92 , 100 S.Ct. at 343 . Every person who walked onto the premises of Johnson’s house on October 16, 1985, possessed constitutional protection against an unreasonable search or an unreasonable seizure. That protection was separate and distinct from the Fourth Amendment protection possessed by Johnson and Robertson, both of whom lived in the house, and one of whom the officers had probable cause to believe was engaging in criminal activity. See id. Beyond mere proximity to Johnson and the house, the government can identify no probable cause which would lead a prudent person to believe that Steeprow had committed or was committing a criminal offense, and thus that her constitutional protection could be intruded upon. 3 See Beck v. Ohio, 379 U.S. 89, 91 , 85 S.Ct. 223, 225-26 , 13 L.Ed.2d 142 (1964); Henry, 361 U.S. at 102 , 80 S.Ct. at 171 . No necessity is shown for stopping Steeprow in order to serve the arrest warrant upon Johnson.

II.

Search of Back Pack

The warrant in this case authorized a search of

The government and the dissent would have us hold that the particularity requirement of the Fourth Amendment 4 was satisfied either by the reference to “appurtenc-es” or to “curtilage.” Steeprow contends that the warrant cannot be read to describe her backpack, and thus that the search of it was a warrantless search in violation of the Fourth Amendment. We reject the government’s and the dissent’s expansive reading of the warrant and agree with Steeprow. The search of Steeprow’s backpack was an unreasonable search which violated the Fourth Amendment.

While recognizing that some warrantless searches do not violate the reasonableness requirement, 5 we have no difficulty in con- *784 eluding that the warrantless search in this case was unreasonable. The Supreme Court and other courts have repeatedly recognized that containers such as backpacks are so closely associated with one’s person that a search of them must be supported by a warrant which satisfies the particularity requirement, or by one of the exceptions to the warrant requirement. In this case, particularity was absent, and no exception to the warrant requirement was available. See Ybarra, 444 U.S. at 92 , 100 S.Ct. at 343 (search of defendant and seizure of contents of pocket not justified by warrant authorizing searches of tavern and bartender); Arkansas v. Sanders, 442 U.S. 753, 762 , 99 S.Ct. 2586, 2592 , 61 L.Ed.2d 235 (1979) (warrantless search of suitcase taken from car not justified by “automobile exception” to warrant requirement); United States v. Sporleder, 635 F.2d 809, 813 (10th Cir.1980) (search of defendant’s pockets not justified by search warrant authorizing search of “premises”); United States v. Branch, 178 App.D.C. 99 , 545 F.2d 177, 182 (D.C.Cir.1976) (search of shoulder bag not authorized by search warrant for apartment). See also United States v. Graham, 638 F.2d 1111, 1114 (7th Cir.) (purses or shoulder bags are appended to the body and thus included within the concept of one’s person), cert. denied, 450 U.S. 1034 , 101 S.Ct. 1748 , 68 L.Ed.2d 231 (1981). In Branch, the D.C. Circuit examined the constitutionality of the search of a shoulder bag of defendant, who arrived on the premises after the search had begun. In holding that the search was unconstitutional, the court stated:

545 F.2d at 178 . See also United States v. Micheli, 487 F.2d 429, 432 (1st Cir.1973) (transient visitor retains expectation of privacy in belongings on premises to be searched) (dictum). Similarly, in the case at bench, the extent of the officers’ knowledge of Steeprow’s criminal activity was that she was leaving a house where the officers had probable cause to believe that criminal activity was afoot. The officers had no indication that Steeprow was a person with a criminal history or who might be inclined to assault them. See Ybarra, 444 U.S. at 94 , 100 S.Ct. at 343-44 . In this sense, Steeprow is indistinguishable from defendants in Ybarra, Branch, and Spor-leder. The officers lacked the benefit of either a warrant or one of the exceptions to the warrant requirement to support a search of her.

We find the government’s reliance on United States v. Williams, 687 F.2d 290, 293 (9th Cir.1982), misplaced. In that case, we held that a search warrant authorizing the search of “premises” supported the search of a lunch box located under a work bench in a cabin. Williams is easily distinguishable. We doubt that a lunchbox sitting on the floor of one's residence can be said to be the equivalent of a shoulder bag carried on one’s person for the purpose of evaluating privacy concerns. The lunchbox in Williams was in a free and stationary position on the premises at the time the search warrant was executed; it was not in the immediate possession of any of the defendants. In Steeprow, the defendant had the backpack in her possession, and refused to surrender it. It was a part of her person in which she possessed a reasonable expectation of privacy. In that sense the backpack is not remotely similar to a lunchbox left resting under a work bench in a cabin. Further, the officers in Williams did not know of the existence of the lunchbox before swearing out the affidavit in support of the search warrant, “inadvertently discovering]” it in searching the cabin. In this case, however, the officers did anything but inadvertently discover the backpack in executing the search warrant. They knew full well that Steep-row had a backpack in her possession that she refused to relinquish. Nevertheless, they failed to describe its existence in the *785 affidavit. It is thus all the more apparent that, although the officers could have insured conformity with the particularity requirement because of their knowledge of the backpack, they failed to do so. Compare Williams, supra at 293.

Notwithstanding these clear distinctions, the government would extend Williams to hold that the presence of a container such as Steeprow’s backpack within the “curti-lage” of premises described in a search warrant would subject them to the search authorized in the warrant. Such an extension would certainly bode ill for the legitimate expectations of privacy of persons unfortunate enough to be located within the physical boundaries of premises described in an affidavit and who have chosen to protect their expectations by carrying containers which are personal to them such as purses, handbags, bookbags, and shoulder bags. Officers armed only with a search warrant for premises could justify warrantless searches of any and all containers carried by persons within the physical area described in the warrant, whether probable cause existed for the search of the containers or not. In such a situation, the government would merely argue that since the container was located within the “curtilage” of the area described in the warrant, no probable cause was necessary to support the search independent of the probable cause for the search of the area described in the warrant. Under the government’s rationale, searches of luggage, briefcases, and other containers which are located within the area for which a search is authorized thus would be justified in the absence of any suspicion whatsoever that they contain anything in which the police have a legitimate interest in viewing. See New York v. Belton, 453 U.S. 454, 472 , 101 S.Ct. 2860, 2870 , 69 L.Ed.2d 768 (1981) (White, J., dissenting). Compare United States v. Brock, 667 F.2d 1311, 1322 (9th Cir.1982) (canister of me-thylamine contained beeper which indicated to officers its whereabouts in area to be searched), cert. denied, 460 U.S. 1022 , 103 S.Ct. 1271 , 75 L.Ed.2d 493 (1983).

Certainly, such a rule violates the principles enunciated by the Supreme Court in United States v. Chadwick, 433 U.S. 1, 12 , 97 S.Ct. 2476, 2484 , 53 L.Ed.2d 538 (1977) and Sanders, 442 U.S. at 762 , 99 S.Ct. at 2592. In Chadwick , the Court held that the warrantless search of a footlocker, in which government agents had probable cause to believe there was contraband, violated the Fourth Amendment. The Court reasoned:

Id. The Court emphasized that luggage is intended as a repository of personal effects, and that luggage contents are not open to public view. See also Sanders, 442 U.S. at 764 , 99 S.Ct. at 2593 (purpose of luggage is to serve as repository for personal items). Moreover, the Court reasoned, once the agents had detained the footlocker and put it under their control, there was not the slightest danger that the footlocker or its contents could have been removed before a warrant could be obtained. Id. at 433 U.S. at 14 , 97 S.Ct. at 2485 . See also Sanders, 442 U.S. at 763 , 99 S.Ct. at 2593 (once police have container securely within their control, exigency of mobility no longer exists). The case at bench presents considerations identical to those in Chadwick and Sanders . Steep-row chose to safeguard a legitimate privacy interest by shielding her personal items in a piece of luggage. Once the agents had detained the luggage, there was not the slightest danger that Steeprow could have removed any of the contents or otherwise posed a danger that she would destroy the contents or threaten the officers’ safety. We thus fail to see how the search of an item so personal to Steeprow could be justi *786 fied under any of the grounds of exigency which generally characterize the well-delineated exceptions to the warrant requirement.

Viewed against the backdrop of Ybarra, Sanders, Chadwick, Branch, and Sporleder, Williams — which involved a lunchbox, not in the possession of a defendant, left under a bench — is at best remotely apposite. If the officers had probable cause to believe that the backpack contained contraband, they should have obtained a warrant which described the backpack and which would have authorized a search of its contents. See Arizona v. Hicks, — U.S. —, 107 S.Ct. 1149, 1155 , 94 L.Ed.2d 347 (1987). Absent that warrant, the search violated the Fourth Amendment. See Ybarra, 444 U.S. at 96 , 100 S.Ct. at 345 ; Sanders, 442 U.S. at 766 , 99 S.Ct. at 2594 ; Chadwick, 433 U.S. at 16 , 97 S.Ct. at 2486 ; Sporleder, 635 F.2d at 813 ; Branch, 545 F.2d at 178 . Evidence obtained as a result should have been suppressed.

The denial of Steeprow’s motion to suppress is reversed, her conviction vacated, and the cause remanded for further proceedings not inconsistent with this opinion.

. The dissent further cites in support of its reasoning United States v. Wiga, 662 F.2d 1325 (9th Cir.1981), cert. denied, 456 U.S. 918 , 102 S.Ct. 1775 , 72 L.Ed.2d 178 (1982), for the proposition that

In Wiga , we sustained the "protective sweep" of the motor home as incident to a lawful arrest of the defendant.

A search incident to arrest is a search which falls within one of the well-delineated exceptions to the warrant requirement.

Chimel v. California, 395 U.S. 752, 763 , 89 S.Ct. 2034, 2040 , 23 L.Ed.2d 685 (1969). See generally New Jersey v. T.L.O., 469 U.S. 325, 356 , 105 S.Ct. 733, 751-52 , 83 L.Ed.2d 720 (1985) (Brennan, J., concurring in part and dissenting in part), infra n. 3.

There is no "search incident to a lawful arrest" issue relating to the detention of Steeprow. The question is whether the detention of Steep-row at gunpoint for a period of several minutes amounted to an arrest in the first place.

*782 We likewise disagree with the dissent's reliance on United States v. Buffington, 815 F.2d 1292 (9th Cir.1987), in which we held that the detention at gunpoint of defendants in a prone position was not an arrest. Crucial to Buffing-ton were: (1) one of the defendants’ known "violent criminal history," id. at 1300 , and (2) defendants’ suspicious activity in “casing" a bank. No similar circumstances appear here. Steeprow had no known criminal history. Her activity consisted only of walking down a path leading from a house in which criminal activity was suspected.

. The dissent makes no attempt to distinguish Strickler and Ramos-Zaragosa beyond the somewhat gossamer observation that they involve seizures of defendants in automobiles rather than outside of houses. This distinction is one without a difference. We fail to see how a person accosted outside of a house, absent other circumstances, is any more likely to pose a threat to officers than one inside an automobile. Indeed, the opposite may be true. See United States v. Russell, 546 F.2d 839, 841 (9th Cir.1976) (officers justified in displaying weapons where defendants in camper with curtained and screened windows at night; conditions "perfect for an ambush") (Wright, J., concurring).

. We realize this state of affairs is not an entirely happy one for law enforcement officials. It is not surprising that such poorly marked boundaries are sometimes transgressed. Our task, however, is to preserve the markings as best we can. We cannot do this by pretending they do not exist.

. The Fourth Amendment requires that warrants be supported by probable cause and "particularly describ[e] the place to be searched, and the persons or things to be seized." The particularity requirement is aimed at protecting against general searches and insures that nothing is left to the discretion of the executing officer. See Marron v. United States, 275 U.S. 192, 196 , 48 S.Ct. 74, 76 , 72 L.Ed. 231 (1927); United States v. Cardwell, 680 F.2d 75, 77 (9th Cir.1982).

. [S]ome special governmental interest beyond the need merely to apprehend lawbreakers is necessary to justify a categorical exception to the warrant requirement. For the most part, special governmental needs sufficient to override the warrant requirement flow from "exigency — that is, from the press of time that *784 makes obtaining a warrant either impossible or hopelessly infeasible, [citations]
