    OPINION
    _________________
    MERRITT, Circuit Judge. In this drug case, the District Court suppressed evidence of a
    methamphetamine laboratory seized by police officers as a result of a warrantless search of a trailer
    home and garage on a remote country road in a farming area of West Tennessee. The officers did
    not seek judicial review and approval in advance as the Fourth Amendment requires except in
    extraordinary circumstances. The government appeals the suppression order primarily on the ground
    that the possible destruction of evidence justified the warrantless search under the “exigent
    circumstances” exception to the warrant requirement. Secondarily, the government also claims as
    an alternative theory that the officers obtained a valid consent to search after their forced entry at
    the home. We will first set out the principles governing warrantless searches for evidence and then
    apply those principles to the situation before us. We will affirm the judgment of the District Court
    1
    Nos. 03-6298/6406 United States v. Chambers                                                       Page 2
    because here there was no emergency justifying a warrantless search and the officers anticipated that
    they would conduct the search and could easily have obtained a search warrant.
    I. Principles Limiting Warrantless Searches Based on “Exigent Circumstances”
    The principles governing warrantless searches based on “exigent circumstances” are fairly
    well settled. In the Fourth Amendment, the Founders required a warrant for searches and seizures
    because they did not trust constables, sheriffs and other officers to decide for themselves when they
    had probable cause to search houses, individuals and places of business. The first and most
    important principle is that searches must ordinarily be cleared in advance as a part of the judicial
    process. In Coolidge v. New Hampshire, 
    403 U.S. 443
    , 454-55 (1971) (footnotes omitted), the
    Supreme Court explained:
    Thus the most basic constitutional rule in this area is that “searches conducted
    outside the judicial process, without prior approval by judge or magistrate, are per
    se unreasonable under the Fourth Amendment—subject only to a few specifically
    established and well-delineated exceptions.” The exceptions are “jealously and
    carefully drawn,” and there must be “a showing by those who seek exemption . . .that
    the exigencies of the situation made that course imperative.” “[T]he burden is on
    those seeking the exemption to show the need for it.”
    (Emphasis added and footnotes omitted.) In order for a warrantless search to pass muster, probable
    cause must exist, but “no amount of probable cause can justify a warrantless seizure,” 
    id. at 471,
    because, in addition, the cause of the search must be based on an “emergency” and hence,
    “inadvertent” or unanticipated. “Where the discovery is anticipated, where the police know in
    advance the location of the evidence and intend to seize it, the situation is altogether different.” 
    Id. at 470.
            Under these principles, officers must seek a warrant based on probable cause when they
    believe in advance they will find contraband or evidence of a crime. They must articulate the basis
    of their belief in the affidavit and bring the matter before a magistrate. When the police go to a
    home with the intention of searching for evidence, they may not forgo a warrant.
    When there is neither a warrant nor consent, courts will only permit a search or seizure to
    stand under extraordinary circumstances. In McDonald v. United States, 
    335 U.S. 451
    (1948),
    “three police officers [without a warrant] surrounded the house” they had had under surveillance for
    two months where they believed that McDonald was conducting a numbers racketeering operation.
    “While outside the house, one of the officers thought he heard an adding machine. These machines
    are frequently used in the numbers operation. Believing that the numbers game was in process, the
    officers sought admission to the house.” 
    Id. at 452.
    They entered the home and seized the evidence
    while the numbers operation was in progress. The Court suppressed the evidence:
    Where, as here, officers are not responding to an emergency, there must be
    compelling reasons to justify the absence of a search warrant . . . . We will not
    assume that where a defendant has been under surveillance for months, no search
    warrant could have been obtained . . . . No reason, except inconvenience of the
    officers and delay in preparing papers and getting before a magistrate, appears for
    the failure to seek a search warrant . . . . Absent some grave emergency, the Fourth
    Amendment has interposed a magistrate between the citizen and the police.
    
    Id. at 454-55
    (emphasis added). The “imperative” and “anticipated” language of Coolidge and the
    “grave emergency” language of McDonald are designed to insure that officers will seek a warrant
    based on probable cause when they have a belief in advance that they will find contraband or
    evidence of a crime. They may only forego a warrant in the case of a true exigency or emergency.
    Nos. 03-6298/6406 United States v. Chambers                                                                   Page 3
    Moreover, for a warrantless search to stand, law enforcement officers must be responding
    to an unanticipated exigency rather than simply creating the exigency for themselves. In United
    States v. Richard, 
    994 F.2d 244
    (5th Cir. 1993), the officers were conducting surveillance of a hotel
    room occupied by suspects. The officers approached the door, knocked, and announced that they
    were police officers. The officers heard the sound of people talking softly, heard doors or drawers
    slamming, and footsteps moving about. The officer kicked the door open and entered the room
    without a warrant. Although officers claimed that they did not have probable cause to obtain a
    warrant in the beginning, the evidence suggested otherwise. 
    Id. at 248.
    The court held that the
    officers could have secured the area around the room while they waited for a warrant; but because
    they did not, the officers had created the exigent circumstances that they wanted to rely on to justify
    their warrantless entry. A “warrantless entry became a foregone conclusion once officers knocked.”
    
    Id. at 249-50.
    McDonald and Richard stand firmly for the proposition that warrantless searches are
    not permitted when the only exigency is one that is of the officer’s creation.
    Likewise, in Ewolski v. City of Brunswick, 
    287 F.3d 492
    , 504 (6th Cir. 2002), we reviewed
    a number of the “created-exigency” cases that apply the emergency and inadvertence principle
    which, we said, cannot be met “if the police controlled the timing of the encounter giving rise to the
    search.” Our review concluded that “the created-exigency cases have typically required some
    showing of deliberate conduct on the part of the police evincing an effort intentionally to evade the
    warrant requirement.” 
    Id. (Emphasis added.)
           II. Application of “Exigent Circumstances” Principles to the Facts of this Case
    The warrantless search in this case turned up extensive evidence of the operation of an
    elaborate meth laboratory that the police believed was at the premises when they arrived. At the
    suppression hearing below, the government offered evidence from the lead officer of the search,
    George Freeman, a narcotics officer for the Sheriff of Fayette County, Tennessee. He testified that
    four months before the search a known confidential informant advised police that the Chambers lab
    was manufacturing methamphetamine at the trailer home and garage where the search was later
    conducted. The informant’s identity was known and his information was clear. There is no claim
    that the informant was anonymous, unreliable or had not given the officers a sound factual basis for
    his statements. Based on the strength of the information from the confidential informant, officers
    conducted both an extensive surveillance of the trailer home and garage from a nearby field for three
    nights and later used helicopter flyovers. The surveillance uncovered frequent nighttime visits to
    this remote location by numerous people in cars, some with out-of-county license plates — visits
    that Officer Freeman believed were   consistent with customers purchasing drugs from the meth lab
    that the informant had described.1 In addition, at the trailer home in this remote farming area, the
    1
    Officer Freeman testified as follows:
    Q:         Now I started this line of questioning by asking you if anything unusual happened, why was this
    activity significant to you?
    A:         ....So with the vehicles coming up and down the road and stopping there for, you know, ten, 15, 20
    minutes and then leaving, it seemed to be significant as far as in and out quick, frequent, which is
    consistent with narcotics activity.
    ....
    Q:         Why did you reach that conclusion?
    A:         It’s been my experience during narcotic investigations that a house where people pull up, either one
    or more occupants stay in the vehicle where the engine is left running and they go in the house for a
    short period of time and then leave, through — through my observations as a police officer that is
    consistent with narcotics sales.
    Nos. 03-6298/6406 United States v. Chambers                                                                   Page 4
    officers observed that Chambers was using surveillance cameras and several high intensity spotlights
    to keep watch over the area — all of which fully corroborated the confidential informant’s report
    to the police. There was now strong, indeed overwhelming, evidence of multiple drug sales at the
    premises on a daily basis, evidence supporting the informant’s statements that a meth lab was in
    frequent operation at the Chambers home. But the officers took no action at this time to secure a
    search warrant despite the incriminating evidence in their possession. No magistrate was asked nor
    has any magistrate ever turned down a request for a warrant in this case.
    At the suppression hearing, narcotics Officer Freeman also testified that the sheriff’s office
    then received an “anonymous” call on October 9, 2002, three months after the surveillance.
    Freeman said that the caller “was adamant that I write this down and stated that the Chambers were
    cooking meth right there on Linwood road right now and that we had better get out there, and hung
    up the phone.” The police now had evidence from a known confidential informant, the strong
    corroboration obtained as a result of their extensive surveillance and evidence from an anonymous
    caller that the drug was being manufactured at the Chambers lab that day. Still the officers did not
    seek a warrant.
    Instead, the officers performed a warrantless “knock and talk investigative technique” that
    Officer Freeman had been taught, a method of investigation requiring the officer to go to a home and
    knock on the door and ask questions in an effort to gain consent to search.2 While en route to the
    Chambers’ home, Freeman called Officer Feathers of the federal DEA task force to advise him to
    be ready for a search at the Chambers residence. Three cars with armed deputies drove to the house
    to participate in this so-called “consensual” encounter.
    They knocked on a glass entry door of the trailer home. A woman came to the glass door
    to answer the knock. She retreated when she saw that the police were at the door. She called out
    that there were police at the door; and the police heard, according to Officer Freeman, footsteps
    scurrying inside the trailer as the woman went into another room. Freeman then used the knock and
    the occupant’s refusal to talk as the justification for entry. The police officers immediately went
    through the door with guns drawn and into the trailer home to begin their search. The officers had
    now entered the home without a warrant after appearing in three cars and after informing the DEA
    task force of the impending search. Why and how exactly the officers thought that the occupants
    were going to destroy an entire operating meth laboratory with heavy equipment and drums of
    chemicals in two detached buildings is not explained.
    After searching for a few minutes and finding incriminating evidence, indicating an operating
    meth lab, Officer Freeman read Chambers, the owner, and his wife, their Miranda rights; and the
    Chambers then signed a consent to search form at the request of officer Freeman. Freeman testified
    that Chambers was under arrest and not free to leave.
    After the entry and search, Freeman called Feathers back and asked him to come. Feathers
    came to the premises with other officers and told Freeman that with the “information that they . . .
    had prior on Mr. Chambers, they [the Feathers group of officers] just wanted to go ahead and stop
    . . . and get a search warrant.” Freeman had not suggested a warrant. Unlike the sheriff’s officers,
    these DEA officers believed a warrant necessary based on the “prior information” they had about
    the Chambers. They would not participate in a search based on exigent circumstances. So at that
    Testimony of George Freeman, Suppression Hearing, Feb. 26, 2003, at pp. 23-24 (J.A. at 166-67).
    2
    “Courts have defined [knock and talk] as ‘a noncustodial procedure [in which] the officer identifies himself
    and asks to talk to the home occupant and then eventually requests permission to search the residence.’” United States
    v. Hardeman, 
    36 F. Supp. 2d 770
    , 777 (E.D. Mich. 1999) (citation omitted). Courts generally have upheld this
    investigative procedure as a legitimate effort to obtain a suspect’s consent to search.
    Nos. 03-6298/6406 United States v. Chambers                                                     Page 5
    point the various officers on the premises waited for the search warrant to arrive, long after the
    initial search had actually been conducted after the warrantless entry.
    The government’s claim that the officers did not have sufficient evidence of probable cause
    even to seek a warrant is more farfetched than the similar claim that the Supreme Court rejected in
    McDonald. Like the Court in McDonald, “[w]e will not assume that where a defendant has been
    under surveillance for months, no search warrant could have been 
    obtained.” 335 U.S. at 454-55
    .
    The officers had the information from the confidential informant, the corroboration gained by their
    extensive surveillance and the anonymous caller evidence. They had advised the DEA in advance
    of the impending search. Clearly, they should have sought a search warrant. Moreover, they
    completely “controlled the timing of the encounter giving rise to the search.” The fact that the
    woman at the door called out “police” and retreated back to another room does not create an exigent
    circumstance. It is her constitutional right. Such a retreat and refusal to allow soldiers or armed
    officers into the home is every citizen’s right under the Fourth Amendment, the very reason for its
    creation. The exercise of this fundamental right against armed invasion of the home is certainly not,
    as the government seems to imply, the “equivalent” to yelling “destroy the drugs” — or “get your
    guns ready” or “try to hide or destroy the boiler and all the lab equipment.” The exercise of a
    constitutional right at the front door of your home not to consent to talk or allow a search does not
    create an exigency justifying a warrantless entry.
    “The burden is on those seeking the exemption [from the warrant requirement] to show the
    need for it,” 
    Coolidge, 403 U.S. at 455
    . There is no showing here at all that a magistrate would not
    have issued the warrant earlier in the day or at some previous time, as he did later in the day upon
    the affidavit of the DEA Task Force. There was no exigency. We therefore conclude that the
    District Court did not err in its conclusion that the government has failed to show the need for an
    exemption from the warrant requirement of the Fourth Amendment.
    The failure to seek a warrant in the face of plentiful probable cause, the timing and
    Freeman’s call to Officer Feathers advising him of the impending search, as well as the arrival with
    three cars and the immediate entry with guns drawn, taken together, meet the requirement of “some
    showing of deliberate conduct on the part of the police evincing an effort to evade the warrant
    requirement.” Even were the Court to find exigent circumstances, the record indicates that any
    exigency was calculated by the police in order to facilitate their warrantless search.
    The freedom from armed intrusions of the home “outside the judicial process, without prior
    approval by judge or magistrate,” as the Supreme Court explained in the Coolidge case quoted
    above, is one of our most “basic” civil liberties. Like the rights of free speech and assembly, trial
    by jury and the right to counsel, it is among the civil liberties the founding generation fought for and
    included in our founding documents — a liberty that the American people have pointed to with pride
    for 200 years. We should continue to take seriously the rule that judicial review is necessary to
    allow such intrusions and not water down the warrant requirement because advanced judicial
    clearance is an inconvenient or inefficient practice that the police or the military are too busy, or
    otherwise unwilling, to observe.
    III. The Consent to Search Issue
    Within a few minutes after the warrantless entry, Officer Freeman encountered Chambers,
    effectively advised him that the officers had looked around briefly and found evidence of
    methamphetamine use and manufacture, read him his Miranda rights and asked him to sign a
    consent to search further. Officer Freeman answered, “Yes” to the question on cross-examination,
    “[Chambers] was actually detained, is that correct, he is not free to leave at the time he was asked
    for the consent to search?” At that point, after the illegal entry and after the officers had found some
    Nos. 03-6298/6406 United States v. Chambers                                                           Page 6
    evidence of the methamphetamine lab they had expected to find, and after Chambers was not free
    to leave, Chambers and his wife then signed a consent to search form.
    The government’s brief correctly states the standard for consent to search after an illegal
    entry:
    When an individual consents to a search after an illegal entry is made, the
    consent is not valid and “suppression is required of any items seized during the
    search..., unless the taint of the initial entry has been dissipated before the ‘consents’
    to search were given.” 
    Buchanan, 904 F.2d at 356
    (quoting United States v.
    Vasquez, 
    638 F.2d 507
    , 527 (2d Cir. 1980), cert. denied, 
    450 U.S. 970
    (1981)).
    “Dissipation of the taint resulting from an illegal entry,” this Court has held,
    “ordinarily involves showing that there was some significant intervening time, space,
    or event.” 
    Id. (quoting Vasquez,
    638 F.2d at 528). Finally, it is the government’s
    burden to show that the defendant’s consent “was sufficiently an act of free will to
    purge the primary taint of the unlawful invasion.” 
    Buchanan, 904 F.2d at 356
             (emphasis in original).
    We agree with the District Court that the consent to search forms were executed by
    Chambers and his wife only a few minutes after the illegal entry by three police officers, after they
    had conducted a brief preliminary search and found evidence of a methamphetamine lab and after
    Chambers was no longer free to leave and therefore effectively under arrest. We agree with the
    District Court as well that these events created a highly coercive atmosphere and that “it would be
    reasonable for Chambers to think that refusing consent would be a futile gesture amounting to no
    more than ‘closing the barn door after the horse is out.’” The District Court credited Chambers’
    testimony: “He asked me if I had the keys to the shed [where the anhydrous was stored], and he had
    me under arrest, I didn’t know what else to do . . . I had no choice in it.” (Op., p. 23, App. 107.)
    Based upon the evidence in the case, we find no error in these findings and the conclusion of the
    District Court as follows:
    Considering the totality of the circumstances, the Court finds that Chambers’ consent
    was the product of the prior illegal entry into his residence. Accordingly, it is
    submitted that the government has not carried its burden to show by a preponderance
    of the evidence through clear and positive testimony that Chambers’ consent was
    voluntary.
    (Op. p. 24, App. p. 108.)
    Accordingly, the judgment of the District Court is AFFIRMED.
    Nos. 03-6298/6406 United States v. Chambers                                                   Page 7

    DISSENT
    _________________
    SUTTON, Circuit Judge, dissenting. As this matter comes to the court, the debate over the
    officers’ initial entry into the house has focused on two questions: whether the officers had probable
    cause to search the house and whether the exigent-circumstances exception allowed them to enter
    the house in the absence of a warrant. The majority acknowledges that probable cause existed to
    conduct a search, a conclusion with which I agree, and suggests that exigent circumstances did not
    exist, a conclusion with which I do not agree—given that the police suspected that drugs and a drug-
    manufacturing operation were in the house, one of the occupants yelled “the police are here” upon
    answering the police officer’s knock on the door, this same occupant “ran” back into the house after
    seeing who was there and other occupants of the house began moving quickly after hearing that the
    police had arrived. Rather than stop there, however, the majority proceeds to invalidate the search
    primarily on the ground that the officers manufactured the exigency, a ground neither argued by the
    defendant nor supported by the facts. Because the manufactured-exigency exception requires
    “deliberate conduct on the part of the police evincing an effort intentionally to evade the warrant
    requirement,” Ewolski v. City of Brunswick, 
    287 F.3d 492
    , 504 (6th Cir. 2002), and because no such
    conduct occurred here, I respectfully disagree with this conclusion as well. I thus would uphold the
    initial search and, after that, the full search to which the defendant freely consented after the
    officers’ initial and permissible entry.
    First, was there probable cause? Under the “flexible, common-sense standard” of probable
    cause, Texas v. Brown, 
    460 U.S. 730
    , 742 (1983), probable cause exists when “the facts available
    to the officer would warrant a man of reasonable caution in the belief that certain items may be
    contraband or stolen property or useful as evidence of a crime,” 
    id. (internal quotations
    marks and
    citation omitted), or when there is “a fair probability that contraband or evidence of a crime [would]
    be found in a particular place,” Illinois v. Gates, 
    462 U.S. 213
    , 238 (1983). The officers satisfied
    this standard.
    In June of 2002, a confidential informant told the police that methamphetamine was being
    manufactured at the Chambers’ house. Surveillance corroborated the tip, revealing an elaborate
    security system beyond that of a typical rural homeowner: motion detectors, floodlights,
    surveillance cameras and a person acting as a lookout. Add to these observations a series of short-
    duration visits made by different people to this rural house late at night in June, all observed by
    Freeman, and it is not surprising that Freeman came to the conclusion that “narcotics activity” was
    afoot. JA 166. Yet because Freeman did not believe he had enough facts at that time to support
    probable cause, he did not seek a warrant to search the house or, for reasons that remain unclear,
    conduct any other surveillance of the house. See JA 199 (Freeman testifying that he did not believe
    he had probable cause prior to the knock-and-talk encounter).
    Roughly four months after the surveillance ended, on October 9, the police received an
    anonymous call about the Chambers’ house. “I’m not going to give you my name,” the caller said,
    “but they’re cooking meth on Linwood, the third or fourth house on the left, the Chambers’
    residence, and you need to get down there quick before somebody gets hurt.” JA 243. Immediately
    after receiving the tip, several officers drove to the Chambers’ home and proceeded to conduct what
    has come to be known as a “knock and talk” consensual encounter. They knocked on the door,
    which was answered by a woman. Upon answering the door, she “ran back into the trailer home out
    of sight, very excited and loudly shouting, ‘The police are here.’” JA 91 (magistrate judge’s
    findings of fact, later adopted by district court). At the same time, the officers heard the sound of
    several other occupants suddenly moving quickly within the house.
    Nos. 03-6298/6406 United States v. Chambers                                                      Page 8
    All of these factors considered—two tips (one by a confidential informant, the other
    anonymous), the surveillance of the house four months earlier and on the day of the search, and the
    reaction of the woman and the other occupants upon the arrival of the police—the police had
    probable cause to believe that criminal activity was taking place in the house on October 9. See
    
    Gates, 462 U.S. at 238
    (explaining that probable cause exists when there is “a fair probability that
    contraband or evidence of a crime [would] be found in a particular place”); United States v.
    Velazquez-Rivera, 
    366 F.3d 661
    , 664 (8th Cir. 2004) (efforts at flight and evasion combined with
    corroborated informant’s tip established probable cause); United States v. Clarence Pennington, 
    328 F.3d 215
    , 221 (6th Cir. 2003) (noting that the “sound of footsteps, indicating someone running away
    from the front door . . . would indicate to a reasonable officer that . . . the person inside the home
    was taking some type of evasive action, including the possible destruction of contraband”); see also
    Illinois v. Wardlow, 
    528 U.S. 119
    , 124 (2000) (“[H]eadlong flight . . . is the consummate act of
    evasion.”).
    Chambers attempts to counter this conclusion by arguing that the events in June were too
    remote in time to be factored into the probable-cause equation. Yet staleness is not measured “solely
    by counting the days on a calendar.” United States v. Spikes, 
    158 F.3d 913
    , 923 (6th Cir. 1998).
    It turns on a host of “variables: the character of the crime (chance encounter in the night or
    regenerating conspiracy?), the criminal (nomadic or entrenched?), the thing to be seized (perishable
    and easily transferable or of enduring utility to its holder?), the place to be searched (mere criminal
    forum of convenience or secure operational base?), etc.” 
    Id. (quotation marks
    omitted). The old and
    new evidence in this instance both pointed in the same direction, namely toward the existence of an
    ongoing methamphetamine laboratory at the Chambers’ house. The two tips, separated by four
    months, each attested that there was a methamphetamine laboratory there; the elaborate home
    security measures suggested a fixed and ongoing operation; the presence of an unusual number of
    automobiles at a dead-end road in a rural location with normally sparse traffic suggested an ongoing
    criminal operation; and the reaction of the woman at the door confirmed that the prior apparent drug
    activity at the house had become the prologue to current drug activity at the house. As these
    variables demonstrate, even when a significant period of time has elapsed since a defendant’s last
    reported criminal activity, it is still possible to infer that wrongdoing continues on the premises. Id.;
    see also United States v. Wright, 
    343 F.3d 849
    , 864 (6th Cir. 2003) (a factor for evaluating staleness
    is whether there is “any corroboration of the older and more recent information”); United States v.
    Johnson, 
    461 F.2d 285
    , 287 (10th Cir. 1972) (when facts indicate “activity of a protracted and
    continuous nature, a course of conduct, the passage of time becomes less significant”). A person
    of reasonable caution, in short, could well have expected to find methamphetamine and the
    equipment used to make it at the Chambers’ house on October 9.
    Second, did exigent circumstances allow the police to enter the house without a warrant?
    The police, the parties agree, may conduct a warrantless search when probable cause exists and
    when they face exigent circumstances, see Groh v. Ramirez, 
    540 U.S. 551
    , 559 (2004), which
    include the risk that evidence of criminal activity will be destroyed, see Coolidge v. New Hampshire,
    
    403 U.S. 443
    , 477–78 (1971) (noting “the basic principle of Fourth Amendment law that searches
    and seizures inside a man’s house without warrant are per se unreasonable in the absence of some
    one of a number of well defined ‘exigent circumstances’” and then discussing the destruction of
    evidence). The police, the parties further agree, may enter a house without a warrant (as well as
    execute a search warrant without knocking and announcing) when “probable cause plus exigent
    circumstances” exist. See Kirk v. Louisiana, 
    536 U.S. 635
    , 638 (2002) (explaining that “police
    officers need either a warrant or probable cause plus exigent circumstances in order to make a lawful
    entry into a home”); United States v. Campbell, 
    261 F.3d 628
    , 632–33 (6th Cir. 2001) (“The law is
    well settled that a warrantless entry will be upheld when the circumstances then extant were such
    as to lead a person of reasonable caution to conclude that such evidence would probably be
    destroyed within the time necessary to obtain a search warrant.”). See also United States v. Douglas
    Pennington, 
    287 F.3d 739
    , 747 (8th Cir. 2002) (holding that officer’s knowledge that drugs had just
    Nos. 03-6298/6406 United States v. Chambers                                                      Page 9
    left the house, that drugs had been found in the residence during a search three months prior, and
    that the house currently smelled of drugs “created exigent circumstances justifying the officers’
    entry into the house to arrest [an occupant] and to prevent the destruction of drug manufacturing
    evidence while they obtained a search warrant”); United States v. Marshall, 
    157 F.3d 477
    , 482 (7th
    Cir. 1998) (holding that the warrantless entry into the suspect’s home was justified because the
    officers reasonably believed the occupant was aware of their presence and preparing to destroy
    evidence). And the police, the parties finally agree, not only may use consensual encounters on the
    street as a legitimate law-enforcement technique, but they also may use consensual encounters at
    a doorstep—a “knock and talk”—as a legitimate investigative technique. See United States v. Jones,
    
    239 F.3d 716
    , 720 (5th Cir. 2001) (“Federal courts have recognized the ‘knock and talk’ strategy
    as a reasonable investigative tool when officers seek to gain an occupant’s consent to search or when
    officers reasonably suspect criminal activity.”); see also 
    Ewolski, 287 F.3d at 504
    (concluding that
    it was reasonable to approach a suspect’s home to attempt to learn more through consensual
    questioning).
    Given these principles, all agree, including defense counsel at oral argument, that the validity
    of this search would have been a lay-down if the woman answered the knock on the door by yelling
    “Police, destroy the drugs.” That response to a legitimate knock on the door by the police assuredly
    would have removed any doubt about probable cause while at the same time establishing the
    requisite exigent circumstances to enter the house and preserve the status quo before obtaining a
    warrant or consent to search. Under these circumstances, the question in this case comes to this:
    Is what the police saw and heard sufficiently akin to yelling “Police, destroy the drugs” as to justify
    the officers’ actions? I think it is.
    For one, while the woman did not yell “Police, destroy the drugs,” she did yell “the police
    are here” and ran down the hallway after answering the door. That is not the way law-abiding
    citizens generally react to an encounter with the police. See Clarence 
    Pennington, 328 F.3d at 221
    (noting that an occupant who runs away from the door when police knock is acting suspiciously);
    cf. Illinois v. Lidster, 
    540 U.S. 419
    , 425 (2004) (“[C]itizens will often react positively when police
    simply ask for their help as responsible citizens to give whatever information they may have to aid
    in law enforcement.”) (quotation marks and brackets omitted). For another, what happened
    immediately after the woman’s reaction to the presence of the police amounted to the visual and
    aural equivalent of “destroy the drugs.” The woman “ran” down the hallway away from the door
    and the officers heard “the sound of people running inside the trailer.” JA 174. At this point, of
    course, the officers did not conduct a full-blown search of the house, but entered the house to
    preserve the status quo. And had the Chambers not eventually consented to the search, there is every
    indication that the group of officers engaged in the investigation would have proceeded to obtain
    a search warrant for the house. JA 185 (testifying in response to the question “did you search the
    house after receiving consent?,” Freeman said, “No, sir, we—we waited” for the DEA agents to
    arrive); JA 196 (recording that when the DEA agents arrived and learned of the evidence initially
    observed, they stopped and waited for a search warrant).
    In view of the reaction of the woman and the other individuals in the house to the arrival of
    the police and in view of the reality that there was probable cause that drugs and drug-manufacturing
    equipment were in the house, exigent circumstances existed to enter the house promptly to control
    the situation. Time and again, courts have recognized that because drugs (and, it follows, the raw
    materials used to make them) are eminently disposable, exigent circumstances will often exist to
    enter a house without knocking and announcing or, as here, without a warrant. See, e.g., United
    States v. Banks, 
    540 U.S. 31
    , 39 (2003) (noting that prudent cocaine dealers keep their drugs near
    a commode or sink for quick disposal in the course of ruling on the appropriate amount of time
    officers must wait to enter a house after knocking on the door); United States v. Elkins, 
    300 F.3d 638
    , 655 (6th Cir. 2002) (“Exigent circumstances permitting police to enter a structure without a
    Nos. 03-6298/6406 United States v. Chambers                                                    Page 10
    warrant may arise when evidence of drug crimes is in danger of destruction.”); see also 
    Campbell, 261 F.3d at 632
    –33 (same).
    Third, does the manufactured-exigency exception (to the exigent-circumstances exception
    to the warrant requirement) alter this conclusion? In the majority’s view, it does; in my view, it does
    not.
    Recognizing the need to give the police reasonable latitude in doing their job, our “created-
    exigency cases have typically required some showing of deliberate conduct on the part of the police
    evincing an effort intentionally to evade the warrant requirement.” 
    Ewolski, 287 F.3d at 504
    (emphasis added). In Ewolski, police received credible evidence that an individual was dangerous
    and volatile and might be a risk to his wife and son. In the course of rejecting an argument that the
    officers’ warrantless entry into the house grew out of a manufactured exigency, Ewolski explained
    what happens when police go to a home to “attempt to learn more through consensual questioning.”
    
    Id. “When an
    officer observes facts giving rise to exigent circumstances in the course of [ ] a
    consensual encounter,” we held, “it usually cannot be said that the officer impermissibly ‘created’
    the exigent circumstances.” 
    Id. at 505.
            Just as facts observed by the police in the course of a consensual encounter “usually” will
    not be treated as deliberately prompting an exigency, so it is true that facts gathered in the course
    of other ordinary police work typically will not be treated as contriving an exigency. In Campbell,
    members of a police narcotics unit intercepted a Federal Express package containing drugs. Seeking
    to catch the intended recipient of the package, the officers removed most of the drugs (replacing
    them with another substance), inserted a transmitting device that would activate upon opening the
    package and obtained a warrant to search the addressed residence. 
    Campbell, 261 F.3d at 629
    –30.
    Undercover officers monitored the delivery of the package, but the suspect defied their expectations
    by taking the package to a different residence. 
    Id. at 630.
    Soon after the suspect arrived at the
    second residence, the transmitter signaled that the suspect had opened the package, after which
    officers entered the residence without a warrant to prevent the destruction of evidence. 
    Id. On appeal
    from the conviction of the suspect, we rejected his claim that the police manufactured the
    exigency, emphasizing that it was the actions of others, not the actions of the police, that established
    the exigency. 
    Id. at 634.
             So it is here. On October 9, the police received an anonymous tip that methamphetamine
    was being “cooked” at the Chambers’ residence and that “you need to get down there quick before
    somebody gets hurt.” See JA 210 (Freeman describing methamphetamine labs as “very explosive”),
    243. At that point, the officers did not believe that they had probable cause sufficient to support a
    search warrant, see JA 199 (Freeman testifying that he did not believe he had probable cause prior
    to the knock-and-talk encounter), and at all events could fairly believe that they did not have time
    to try to get a warrant given the nature of the tip. The only deliberate conduct of the police under
    these circumstances was to use a reasonable investigative tool—the consensual encounter—to gather
    more evidence and to do so quickly. When the residents of the house responded to this legitimate
    law-enforcement technique in incriminating and risky ways—by yelling “Police” and running back
    into the house in one instance and by moving suddenly and quickly around the house in other
    instances—it was the residents, not the police, who created the danger that evidence of drug activity
    would soon disappear. As Ewolski makes clear, “[w]hen an officer observes facts giving rise to
    exigent circumstances in the course of such a consensual encounter, it usually cannot be said that
    the officer impermissibly ‘created’ the exigent 
    circumstances.” 287 F.3d at 505
    . All of this may
    explain why Chambers did not rely on the manufactured-exigency exception below or in the court
    of appeals.
    While the majority gives several explanations for applying the manufactured-exigency
    exception here, I do not find them convincing. The one case cited by the majority in which a
    Nos. 03-6298/6406 United States v. Chambers                                                  Page 11
    manufactured exigency was found, United States v. Richard, 
    994 F.2d 244
    (5th Cir. 1993), does not
    cover our circumstances. There, police suspected a man of drug smuggling, knocked on his door
    and announced that they were police officers. When the occupants responded, “Okay. Okay. Wait
    a minute,” but did not open the door quickly, the police forced themselves into the hotel room. 
    Id. at 246–47.
    Noting that the officers did not have a warrant and did not have probable cause of illegal
    activity before they entered the room and that the officers “did not know what, if any, evidence [the
    hotel room] might contain,” the Fifth Circuit understandably did not accept the government’s claim
    that “the possibility of destruction of evidence” provided an exigent circumstance. 
    Id. at 249.
    I
    agree with the resolution of Richard but not its application here. In Richard, unlike our case, the
    police did not have probable cause of drug activity before entering the hotel room. And in Richard,
    unlike our case, the residents did nothing unusual or incriminating in answering the door that would
    have created probable cause or a drug-offense-related exigency.
    While the majority relies on language in Coolidge for the proposition that the discovery of
    evidence must be “inadvertent” or “unanticipated” to justify a warrantless entry, the inadvertence
    requirement, as the majority’s citations demonstrate, see ante at 2, applies to the plain-view
    exception, not the destruction-of-evidence exception, see 
    Coolidge, 403 U.S. at 469
    , 471 (stating
    that “the discovery of evidence in plain view must be inadvertent” and that an intrusion to seize
    “objects—not contraband nor stolen nor dangerous in themselves—which the police know in
    advance they will find in plain view and intend to seize, would fly in the face of the basic rule that
    no amount of probable cause can justify a warrantless seizure”). Removing any doubt on this score,
    the Supreme Court more recently has held that “even though inadvertence is a characteristic of most
    legitimate ‘plain-view’ seizures, it is not a necessary condition.” Horton v. California, 
    496 U.S. 128
    , 130 (1990).
    Nor do I see how McDonald v. United States, 
    335 U.S. 451
    (1948), advances the majority’s
    analysis. McDonald suppressed evidence found during a warrantless search because exigent
    circumstances did not justify the entry. “[T]he defendant,” the Court observed, “was not fleeing or
    seeking to escape. Officers were there to apprehend petitioners in case they tried to leave. Nor was
    the property in the process of destruction nor as likely to be destroyed as the opium in the Johnson
    case.” 
    Id. at 455.
    Since the police went promptly to the house in response to a tip that “you need
    to get down there quick before somebody gets hurt” and proceeded to act in response to the likely
    destruction of evidence, McDonald reinforces the propriety of the officers’ actions.
    Nor can I agree with the majority that because some meth lab components cannot be quickly
    destroyed the police faced no threat of evidence destruction. Certainly the most incriminating
    evidence, the methamphetamine itself, could be quickly flushed or otherwise destroyed. As the
    indictment shows, destroying the methamphetamine would reduce the seriousness of the offenses
    considerably. Compare JA 11 (listing count one, manufacturing a detectable amount of
    methamphetamine in violation of 21 U.S.C. § 841(a)(1), as including a 20-year maximum sentence)
    with JA 13 (listing count three, possessing materials which could be used to manufacture a
    controlled substance in violation of 21 U.S.C. § 843(a)(6), as carrying a 10-year maximum
    sentence). Nothing about the exigent-circumstances exception requires the police to wait patiently
    outside because the suspects could destroy only some, but not all, of the evidence.
    Neither can I agree that the potential existence of probable cause before the knock and
    announce proves that the officers contrived this exigency. While there may be reasons to criticize
    law-enforcement reticence in responding to evidence of criminal activity and while there may be
    reasons to criticize law enforcement for failing to appreciate that they have probable cause that
    criminal activity is afoot, I should not think the Fourth Amendment is one of them. It is far from
    self evident that a restrained attitude toward the quantum of evidence needed to establish probable
    cause is a police failing. Moreover, making the manufactured-exigency exception applicable
    whenever courts (though not the police) conclude that probable cause existed before the encounter
    Nos. 03-6298/6406 United States v. Chambers                                                    Page 12
    would create a peculiar rule in which searches could be invalidated either because the police did not
    have probable cause or because they did.
    Nor do I agree with the majority’s other explanations for finding a manufactured
    exigency—the decision to go to the Chambers’ house after receiving the anonymous tip rather than
    seeking a warrant, the call to the DEA agent before arriving at the Chambers’ house and the number
    of police that went to the house. The officers’ decision not to seek a warrant after the anonymous
    tip on October 9 was no less likely a result of the tipper’s concern that “you need to get down there
    quick before somebody gets hurt” than it was to gin up an exigent circumstance. See JA 210
    (Freeman describing methamphetamine labs as “very explosive”). The decision to tell the DEA
    agent that there would likely be a search later that day at the Chambers’ house was sensible as well.
    In light of the tip, the trip to the Chambers’ house could well have led to sufficient evidence of
    probable cause and consent to search or to the request for a warrant. Either way, the services of an
    expert on methamphetamine laboratories might well be needed. And the number of officers that
    went to the house had no impact on the exigency that arose and was again a sensible response to
    what was plainly a serious investigation.
    Despite my disagreement with the majority, I am not unmindful of the risk here—the
    potential of undermining the warrant requirement and of doing so where it is needed most, the home.
    Yet the traditional rules governing the exigent-circumstances exception, not the alteration of the test,
    ought to address this concern. Police, for example, may not cry exigent circumstances whenever
    probable cause exists that readily disposable drugs are in the home—no matter what the response
    of the resident happens to be. Otherwise, all knock-and-talk encounters would generate the exigency
    merely by the appearance of the officers. For my part, the question remains whether the resident’s
    reaction is the verbal, visual or aural equivalent of “The police are here, destroy the drugs.” Here
    it was. In most cases, it presumably will not be. See United States v. Renfro, 
    620 F.2d 569
    , 575 (6th
    Cir. 1980) (“The government is not relying on the defendant’s knowledge of the police presence
    alone as creating the exigent circumstances justifying the warrantless entry. [The defendants’]
    actions in attempting to destroy evidence were a sudden intervening development which changed
    the complexion of the entire incident and necessitated immediate action.”).
    Nor will a ruling for the government in this case lead officers customarily to avoid seeking
    a warrant (even when they already have probable cause) on the theory that the residents will react
    to their presence in a way that creates an exigency. That is a gamble no sensible officer would
    take—unless, as here, the officers were told to go to the house immediately because “somebody”
    is going to “get[] hurt.” When no one answers the door (even if the residents are home), when no
    one at the home is willing to talk about the matter or when no one at the home does anything
    incriminating, the investigation will have reached a conspicuously low point. The officers will have
    to leave, and the drug manufacturer will have the kind of warning that even the most elaborate
    security system cannot provide.
    For these reasons, I respectfully dissent.
