    SUMMARY*
    Civil Rights
    The panel affirmed the district court’s summary judgment
    in favor of police officers in an action brought under
    42 U.S.C. § 1983 alleging that the officers falsely arrested
    plaintiff without probable cause after unlawfully entering the
    curtilage of her home to approach the back door.
    The panel held that the exclusionary rule does not apply
    in § 1983 cases, and therefore police officers may rely on
    unlawfully obtained evidence to defend themselves against a
    constitutional tort action for false arrest. Accordingly, the
    panel rejected plaintiff’s argument that the officers’ unlawful
    entry into her home’s curtilage necessarily tainted the arrest
    that followed. The panel held that the officers had probable
    cause to arrest plaintiff for endangering the welfare of a
    minor, in violation of Or. Rev. Stat. § 163.575, after smelling
    marijuana emanating from her house.

    OPINION
    O’SCANNLAIN, Circuit Judge:
    We must decide whether police officers may rely on
    unlawfully obtained evidence to defend themselves against a
    constitutional tort action for false arrest.
    I
    A
    On the afternoon of June 13, 2010, Lia Lingo was
    engaged in an ongoing dispute with her neighbor, Suzanne
    Tegroen, regarding Tegroen’s pet dog. In the course of the
    day, Lingo and Tegroen each contacted the Salem, Oregon,
    Police Department, and that night Officer Steven Elmore was
    dispatched to Tegroen’s residence to investigate. Tegroen
    told Elmore that she felt verbally abused by Lingo and felt the
    need to tread lightly around her; Elmore responded that
    Lingo’s conduct did not sound criminal, but that he would try
    to speak with Lingo to ease tensions.
    Elmore walked to Lingo’s house and noticed that its rear
    outside light was on. Rather than go to the home’s front door,
    Elmore walked through Lingo’s carport and knocked on the
    rear door located within. Stephanie Moore, a visitor,
    answered the door and went to retrieve Lingo to speak with
    Elmore. Elmore stated that as soon as Moore opened the
    door, he smelled marijuana.
    Lingo came outside to speak with Elmore, and he asked
    her about the marijuana odor. Lingo explained that she was
    burning hemp-scented incense—which she admitted smells
    LINGO V. CITY OF SALEM                    5
    like marijuana—but insisted that she had no actual marijuana
    inside. Skeptical, Elmore asked for permission to search
    Lingo’s house; Lingo refused. Later, another officer, Justin
    Carney, arrived at Lingo’s house to join Elmore. Carney
    stated that he also smelled marijuana coming from the house,
    and again the officers asked for permission to search the
    home. Lingo again refused.
    At some point during the course of Elmore’s discussion
    with Lingo, Lingo’s seven-year-old child opened the back
    door and peered out. Elmore asked Lingo if there were
    children in her home, and she confirmed that she lived with
    her two minor children. Eventually, after Lingo’s repeated
    refusals to allow the officers to search her home, they placed
    her under arrest for endangering the welfare of a minor, in
    violation of Or. Rev. Stat. § 163.575.
    After Lingo was arrested, Elmore went into the home and
    collected the two children so that they could be moved
    somewhere safer. While Lingo sat in Elmore’s police car, the
    children sat in the carport and eventually in the back of
    Carney’s police car. At Lingo’s direction, the children were
    brought to her great aunt’s house under Oregon Department
    of Human Services supervision, where they remained for
    eight days.
    Following Lingo’s arrest, the police obtained a warrant to
    search Lingo’s home for controlled substances, based upon an
    affidavit from Elmore describing the marijuana odor he
    smelled at her house. Pursuant to the warrant, Salem police
    searched Lingo’s home and found several glass bongs, 1.8
    grams of marijuana (including packaging), small baggies
    commonly used as drug packaging materials, and a small
    6                 LINGO V. CITY OF SALEM
    amount of Klonopin, which is a schedule IV prescription
    drug.
    B
    Lingo was charged by the Marion County District
    Attorney with two counts of child endangerment under Or.
    Rev. Stat. § 163.575. Before trial, Lingo moved to suppress
    evidence the police obtained in their search of her home,
    arguing that Officers Elmore and Carney violated the Fourth
    Amendment by entering her carport and approaching her
    home’s back door. Lingo argued that any evidence collected
    by the police thereafter should be suppressed as the fruit of
    that initial unlawful search. The trial court agreed and
    granted Lingo’s motion to suppress. The charges against
    Lingo were later dropped.
    C
    Lingo then filed suit under 42 U.S.C. § 1983 against
    Elmore, Carney, and the City of Salem, alleging that the
    officers violated the First, Fourth, and Fourteenth
    Amendments of the federal Constitution by falsely arresting
    her without probable cause and by interfering with her (and
    her children’s) right to familial association by causing her
    children to be removed from her home. She sought both
    compensatory and punitive damages.
    The officers and the City moved for summary judgment,
    and Lingo moved for partial summary judgment. In her
    motion, Lingo argued that the officers violated her Fourth
    Amendment rights by entering the curtilage of her home to
    approach the back door. Lingo’s motion did not specify how
    that violation related to her claims for false arrest or wrongful
    LINGO V. CITY OF SALEM                               7
    separation from her children. Perhaps anticipating that, if she
    prevailed on her motion, Lingo would then attempt to prevent
    the officers from introducing evidence obtained in violation
    of the Fourth Amendment to defend themselves and to justify
    their decision to arrest her, the district court requested
    briefing on the issue of whether the exclusionary rule had any
    application in this § 1983 case.
    After receiving the supplemental briefing, the district
    court agreed with Lingo that the officers had indeed violated
    the Fourth Amendment by entering her home’s curtilage, but
    concluded that the exclusionary rule does not apply to § 1983
    claims. The court thus held that the officer’s initial Fourth
    Amendment violation did not taint their ultimate arrest of
    Lingo and found that, based on the marijuana they smelled at
    the house, the officers indeed had probable cause to arrest
    her. The court further held that the officers permissibly
    relocated Lingo’s children to her aunt’s home, where they
    would be away from the suspected marijuana use and where
    they would not be left home alone. Finally, the court
    concluded that Lingo had not adequately demonstrated
    municipal liability. The court granted summary judgment for
    all defendants.
    Lingo timely appealed.
    D
    On appeal, Lingo challenges only the district court’s
    ruling that her arrest was valid.1 Specifically, she contends
    1
    Lingo does not challenge the district court’s conclusion that, if the
    arrest was valid, so too was the officers’ decision to relocate her children,
    nor does she challenge the court’s determination that Lingo failed to
    8                        LINGO V. CITY OF SALEM
    that the district court erred in concluding that the officers had
    probable cause to arrest her. She argues that such conclusion
    was flawed because: (1) the officers may not establish
    probable cause through evidence they gathered as a result of
    their illegal entry into her carport; and (2) in any event, the
    undisputed facts at the scene did not support a finding of
    probable cause.
    We address each argument in turn.
    II
    Lingo’s primary argument on appeal is that the officers’
    unlawful entry into her home’s curtilage necessarily tainted
    the arrest that followed. Drawing from the exclusionary
    rule’s fruit-of-the-poisonous-tree doctrine, she argues that,
    because the officers were not constitutionally permitted to
    stand at her house’s back door,2 they did not have probable
    cause to arrest her on the basis of evidence they perceived
    from that unlawful vantage point.
    A
    We first consider Lingo’s contention that the exclusionary
    rule itself should apply in a § 1983 case.3
    demonstrate municipal liability on behalf of the City.
    2
    On appeal, the officers do not challenge the district court’s conclusion
    that they violated the Fourth Amendment by entering the carport and
    approaching the back door of Lingo’s home.
    3
    Both the district court and the parties have focused on the issue of
    whether the exclusionary rule applies in § 1983 cases. That strikes us as
    a somewhat unusual question to ask here. As explained below, the
    LINGO V. CITY OF SALEM                              9
    Of course, the government may not use evidence seized
    during an unlawful search as proof against the victim at
    criminal trial. See Wong Sun v. United States, 
    371 U.S. 471
    ,
    484 (1963). The “fruit of the poisonous tree” doctrine
    extends the exclusionary rule to require suppression of other
    evidence that is derived from—and is thus tainted by—the
    illegal search or seizure. See 
    id. at 487–88.
    These rules are
    not constitutionally required, but instead are “judicially
    created means of deterring illegal searches and seizures.”
    Penn. Bd. of Prob. & Parole v. Scott, 
    524 U.S. 357
    , 363
    (1998). And “because the [exclusionary] rule is prudential
    rather than constitutionally mandated,” courts apply it “only
    where its deterrence benefits outweigh its substantial social
    costs.” 
    Id. (internal quotation
    marks omitted). Suppression
    of evidence through the rule “has always been our last resort,
    not our first impulse.” Hudson v. Michigan, 
    547 U.S. 586
    ,
    591 (2006).
    The exclusionary rule is not “a personal constitutional
    right of the party aggrieved.” United States v. Calandra,
    
    414 U.S. 338
    , 348 (1974). Correspondingly, the rule “does
    not proscribe the introduction of illegally seized evidence in
    all proceedings or against all persons.” Penn. Bd. of 
    Prob., 524 U.S. at 363
    (internal quotation marks omitted). Indeed,
    the Supreme Court has “repeatedly declined to extend the
    exclusionary rule to proceedings other than criminal trials.”
    
    Id. For example,
    the Court has held that the rule generally
    exclusionary rule is only an evidentiary remedy, which prohibits the use
    of certain evidence at criminal trial. But we find no indication in the
    record that Lingo ever sought to exclude evidence in this case on the basis
    of such rule. Accordingly, even if we were to conclude that the
    exclusionary rule does apply to this action, it is unclear whether there is
    any evidentiary ruling that would be affected by that conclusion.
    10               LINGO V. CITY OF SALEM
    does not apply to grand jury proceedings, civil tax
    proceedings, civil deportation proceedings, or parole
    revocation proceedings. See 
    id. at 363–64;
    but see Lopez-
    Rodriguez v. Mukasey, 
    536 F.3d 1012
    , 1015–16 (9th Cir.
    2008) (holding that the exclusionary rule may still apply in
    deportation proceedings where the government committed an
    “egregious” constitutional violation).
    Critical here, “standing to invoke the exclusionary rule
    has been confined to situations where the Government seeks
    to use such evidence to incriminate the victim of the unlawful
    search.” 
    Calandra, 414 U.S. at 348
    (emphasis added). This
    limitation makes sense: the need to deter unlawful conduct is
    strongest when that conduct could result in criminal sanction
    for the victim of the search. 
    Id. Moreover, preventing
    the
    government from using evidence in such settings takes away
    an obvious incentive—the successful prosecution of
    crime—that may otherwise induce the government to ignore
    constitutional rights. See generally Elkins v. United States,
    
    364 U.S. 206
    , 217 (1960) (purpose of exclusionary rule is to
    “remov[e] the incentive to disregard” the Fourth
    Amendment).
    Conversely, in a § 1983 suit, the need for deterrence is
    minimal. Here, application of the exclusionary rule would
    not prevent the State from using illegally obtained evidence
    against someone, but instead would prevent state actors
    merely from defending themselves against a claim for
    monetary damages. Exclusion of evidence in this context
    would not remove any preexisting incentive that the
    government might have to seize evidence unlawfully. It
    would simply increase state actors’ financial exposure in tort
    cases that happen to involve illegally seized evidence. In
    effect, § 1983 plaintiffs would receive a windfall allowing
    LINGO V. CITY OF SALEM                           11
    them to prevail on tort claims that might otherwise have been
    defeated if critical evidence had not been suppressed. Even
    if such application of the rule might in some way deter
    violative conduct, that deterrence would impose an extreme
    cost to law enforcement officers that is not generally
    countenanced by the doctrine. See Black v. Wigington,
    
    811 F.3d 1259
    , 1268 (11th Cir. 2016) (“The cost of applying
    the exclusionary rule in [the § 1983] context is significant . . .
    [a]nd the deterrence benefits are miniscule.”); Townes v. City
    of New York, 
    176 F.3d 138
    , 148 (2d Cir. 1999) (observing
    that the availability of exclusionary rule in § 1983 cases
    “would vastly overdeter police officers and would result in a
    wealth transfer that is peculiar, if not perverse” (internal
    quotation marks omitted)); see also United States v. Leon,
    
    468 U.S. 897
    , 907 (1984) (“The substantial social costs
    exacted by the exclusionary rule for the vindication of Fourth
    Amendment rights have long been a source of concern.”).
    For these reasons, federal courts of appeals have widely
    held that the exclusionary rule does not apply in § 1983 cases.
    See, e.g., 
    Black, 811 F.3d at 1268
    ; 
    Townes, 176 F.3d at 145
    –46; Wren v. Towe, 
    130 F.3d 1154
    , 1158 (5th Cir. 1997)
    (per curiam); Machado v. Weare Police Dep’t, 494 F. App’x
    102, 106 (1st Cir. 2012) (per curiam). We agree, and we join
    those courts now.4
    4
    Lingo mostly ignores the many cases which have rejected her
    argument, and instead focuses on an inapposite doctrine: the distinction
    between “intrasovereign” and “intersovereign” applications of the
    exclusionary rule, highlighted by the Supreme Court in United States v.
    Janis, 
    428 U.S. 433
    (1976).
    In Janis, the Court held that the exclusionary rule did not require
    exclusion from a federal civil tax proceeding evidence that had been
    unlawfully obtained by state law enforcement agents. 
    Id. at 459–60.
    12                    LINGO V. CITY OF SALEM
    B
    Lingo’s briefs might be read to suggest that the principles
    underlying the fruit-of-the-poisonous-tree doctrine mean that
    information which was obtained in violation of the Fourth
    Amendment may not be used as probable cause to arrest her.
    In other words, Lingo suggests that perhaps the Fourth
    Amendment prohibits not only unlawful searches but also any
    arrest that is justified solely on the basis of evidence procured
    Recognizing that some courts had applied the exclusionary rule in certain
    civil enforcement actions, the Court distinguished those courts’ approval
    of intrasovereign applications of the rule (in which the same sovereign
    that was responsible for the underlying Fourth Amendment violation later
    sought to use its own illegally obtained evidence) from intersovereign
    applications (in which a sovereign sought to introduce evidence that had
    been illegally obtained by a completely separate sovereign). 
    Id. at 455–58.
    Without commenting on the validity of intrasovereign
    application of the rule, the Court held that, at a minimum, the purposes of
    the exclusionary rule are not served by imposing the rule in a civil
    intersovereign case. 
    Id. Lingo argues
    that Janis suggests that the exclusionary rule should be
    applied in an intrasovereign § 1983 case. But this argument turns Janis
    on its head. The Court’s discussion in Janis shows that the core
    application of the exclusionary rule is confined to the criminal context.
    See 
    id. at 446–47.
    The Court addressed the intrasovereign / intersovereign
    distinction only to identify yet another constraint on the rule: even in those
    limited civil cases in which some courts might be inclined to apply the
    rule, they may not do so in the intersovereign context. See 
    id. at 455–58.
    But the fact that the exclusionary never applies in intersovereign civil
    cases says nothing for when the rule ought to apply in intrasovereign
    cases.
    Accordingly, regardless whether this is an intrasovereign or an
    intersovereign case, that fact would not alter our conclusion that the
    exclusionary rule does not apply in a § 1983 case.
    LINGO V. CITY OF SALEM                     13
    from such an unlawful search.         We find no authority
    supporting such an argument.
    As noted above, the exclusionary rule and its fruit-of-the-
    poisonous-tree doctrine are “judicially created remed[ies]
    designed to safeguard Fourth Amendment rights generally
    through [their] deterrent effect, rather than a personal
    constitutional right of the party aggrieved.” 
    Calandra, 414 U.S. at 348
    . The wrong condemned by the Fourth
    Amendment is the invasion of an individual’s privacy. That
    wrong is already “fully accomplished by the unlawful search
    or seizure itself, and the exclusionary rule is neither intended
    nor able to cure” that wrong after it has occurred. 
    Leon, 468 U.S. at 906
    (internal quotation marks and citation
    omitted); accord 
    Calandra, 414 U.S. at 347
    . Accordingly,
    “the use of fruits of a past unlawful search or seizure works
    no new Fourth Amendment wrong.” 
    Leon, 468 U.S. at 906
    (internal quotation marks and alteration omitted) (emphasis
    added).
    For these reasons, nothing within the fruit-of-the-
    poisonous-tree doctrine suggests that an officer must ignore
    facts that would give him probable cause to arrest a person
    merely because those facts were procured through an
    unlawful search. Indeed, as a general matter, probable cause
    determinations depend on the substance of the information
    known to the officer, not whether that information would be
    admissible in court. See Crowe v. County of San Diego,
    
    608 F.3d 406
    , 432 (9th Cir. 2010) (noting that evidence
    establishing probable cause need not be admissible). And as
    the Second Circuit explained in rejecting an argument similar
    to Lingo’s, “[t]he evil of an unreasonable search or seizure is
    that it invades privacy, not that it uncovers crime, which is no
    evil at all.” 
    Townes, 176 F.3d at 148
    . The exclusionary rule
    14                LINGO V. CITY OF SALEM
    already provides a person in Lingo’s position “an enormous
    benefit by reason of the illegal . . . search to which [she] was
    subjected: [her] freedom, achieved by the suppression of
    evidence” at criminal trial. 
    Id. But the
    Supreme Court has
    made clear that this suppression remedy does not mean that
    the government’s use of illegally obtained evidence is itself
    a constitutional concern. See, e.g., Penn. Bd. of 
    Prob., 524 U.S. at 362
    (“We have emphasized repeatedly that the
    government’s use of evidence obtained in violation of the
    Fourth Amendment does not itself violate the Constitution.”).
    Once again, the federal courts of appeals that have
    considered this issue appear to be in accord: “The lack of
    probable cause to . . . search does not vitiate the probable
    cause to arrest” on the basis of evidence found in that search.
    
    Townes, 176 F.3d at 149
    ; see also 
    Black, 811 F.3d at 1268
    (“[O]fficers can rely on [illegally obtained evidence] to prove
    that the arrest warrants were supported by probable cause.”);
    Hector v. Watt, 
    235 F.3d 154
    , 157 (3d Cir. 2001) (“Victims
    of unreasonable searches or seizures may recover damages
    directly related to the invasion of their privacy . . . but such
    victims cannot be compensated for injuries that result from
    the discovery of incriminating evidence and consequent
    criminal prosecution.” (internal quotation marks omitted));
    Vigeant v. United States, 245 F. App’x 23, 24–25 (1st Cir.
    2007) (per curiam) (agents executing an invalid search
    warrant had probable cause to arrest homeowner after
    discovering firearms in the house). We again agree, and we
    join those courts in rejecting Lingo’s suggestion that probable
    cause to arrest may be supported only by information that was
    obtained in accordance with the Fourth Amendment.

    III
    Finally, Lingo argues that even if the officers are
    permitted to justify their decision to arrest her through
    evidence they obtained unlawfully, there are genuine issues
    of fact regarding whether the circumstances in this case gave
    the officers probable cause to arrest her. “Probable cause for
    a warrantless arrest arises when the facts and circumstances
    within the officer’s knowledge are sufficient to warrant a
    prudent person to believe that the suspect has committed an
    offense.” 
    Crowe, 608 F.3d at 432
    (internal quotation marks
    and ellipsis omitted). The facts must be such that a prudent
    person would conclude that there was a “fair probability” the
    individual committed the crime. 
    Id. (internal quotation
    marks
    omitted).
    Lingo was arrested and charged with violation of Or. Rev.
    Stat. § 163.575, which, among other things, makes it a crime
    to “[p]ermit[] a person under 18 years of age to enter or
    remain in a place where unlawful activity involving
    controlled substances is maintained or conducted.” 
    Id. § 163.575(1)(b).
    Marijuana is a Schedule II controlled
    substance in Oregon, Or. Admin. R. 855-080-0022 (2016)
    (Schedule of Controlled Substances), and at the time of arrest,
    it was unlawful for any person in Oregon “knowingly or
    intentionally to possess marijuana,” Or. Rev. Stat. § 475.864,
    unless the person held a valid medical marijuana card, see
    Emerald Steel Fabricators, Inc. v. Bureau of Labor & Indus.,
    
    230 P.3d 518
    , 519–20 (Or. 2010).
    There is little question that the officers had probable
    cause to arrest Lingo for this offense. Both officers at the
    scene stated that they smelled a strong marijuana odor
    emanating from Lingo’s house. Both officers were trained to
    16               LINGO V. CITY OF SALEM
    detect such odors, and Lingo herself admitted the presence of
    such an odor. Prior to the arrest, Elmore ran a records check
    on Lingo and confirmed that she did not have a medical
    marijuana card and that the house was not a registered
    medical marijuana grow site. In other words, the officers
    knew it was unlawful for Lingo knowingly to possess
    marijuana, and, in turn, that it was a crime for her to allow
    minors to remain in a place in which she did. Once the
    officers saw one of Lingo’s children—and once Lingo herself
    told the officers that she had two minor children in the
    house—the underlying facts needed to sustain a violation of
    section 163.575 were complete. In short, the combination of
    the marijuana odor, the undisputed presence of Lingo’s
    children in the house, and the fact that Lingo did not have
    medical marijuana privileges gave the officers probable cause
    to believe that Lingo had committed a crime. See, e.g.,
    United States v. Kerr, 
    876 F.2d 1440
    , 1445 (9th Cir. 1989)
    (“[T]he presence of the odor of contraband may itself be
    sufficient to establish probable cause.”); United States v.
    Barron, 
    472 F.2d 1215
    , 1217 (9th Cir. 1973) (per curiam)
    (“[T]he fact that an agent familiar with the odor of
    marijuana[] smelled such an odor emanating from the
    automobile . . . alone was sufficient to constitute probable
    cause . . . .”); State v. Derrah, 
    84 P.3d 1084
    , 1087 (Or. Ct.
    App. 2004) (“The scent of marijuana, emanating from a
    residence, without more, is sufficient to support a conclusion
    that marijuana will likely be found inside that residence.”).
    Lingo does not dispute the well-founded conclusion
    that—if the officers could smell marijuana—they had
    probable cause to arrest her. Instead, she makes a passing
    attempt to cast doubt on the veracity of the officers’
    assertions that they actually smelled the drug, by noting how
    little marijuana was later found in her home. But Lingo’s
    LINGO V. CITY OF SALEM                    17
    skepticism flies in the face of her own admission that she told
    the officers they smelled hemp incense, which she said
    does—and is intended to—smell like marijuana. In other
    words, it is undisputed that there was a marijuana-like odor,
    even if Lingo insists that the officers could not rule out the
    possibility that the odor came from something other than
    marijuana itself.
    It is decidedly not the officers’ burden to “rule out the
    possibility of innocent behavior” in order to establish
    probable cause. Ramirez v. City of Buena Park, 
    560 F.3d 1012
    , 1024 (9th Cir. 2009) (internal quotation marks
    omitted). Indeed, “[r]arely will a suspect fail to proffer an
    innocent explanation for his suspicious behavior.” 
    Id. Thus, the
    mere fact that Lingo suggested a potential lawful source
    of the marijuana-like odor does nothing to contradict the
    officers’ statements that such an odor existed. In short, Lingo
    gives no reason to doubt that the officers indeed smelled what
    they suspected to be marijuana; as explained above, such odor
    gave the officers probable cause to arrest Lingo under Oregon
    law.
    IV
    For the foregoing reasons, the judgment of the district
    court is AFFIRMED.
