    OPINION
    GOULD, Circuit Judge:
    We here consider the free speech rights of Christian evan-
    gelists who operate religious outreach with the use of ampli-
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        4693
    fied sound in the streets of San Francisco, and whose efforts
    have collided with the City of San Francisco’s prerogative
    under its noise ordinance and permitting scheme to ensure
    that its citizens are not subject to unreasonably loud speech
    and music. Plaintiffs-Appellants Lawrence Rosenbaum and
    Eric Livingston filed suit in the Northern District of Califor-
    nia alleging constitutional claims under the First and Four-
    teenth Amendments that arose out of appellee City of San
    Francisco’s permitting process and noise ordinance enforce-
    ment, which the district court denied after a bench trial. We
    have jurisdiction under 28 U.S.C. § 1291.
    On appeal, appellants claim that San Francisco police offi-
    cers unevenly enforced the municipal noise ordinance, in vio-
    lation of equal protection, by frequently stopping or
    conditioning appellants’ use of amplified sound while leaving
    other groups’ and individuals’ loudspeaker use unmolested.
    Appellants also contend that city officials engaged in view-
    point discrimination. In particular, appellants claim that city
    officials implemented a “heckler’s veto” by responding to
    complaints by citizens who were hostile to appellants’ Chris-
    tian message. Appellants lodge a second viewpoint discrimi-
    nation claim that issuance of permits and enforcement were
    marred by unbridled discretion, and that city police stopped
    giving permits to appellants for amplified sound activities
    relying on noise abatement as a pretext to mask viewpoint dis-
    crimination. As a third viewpoint discrimination claim, appel-
    lants assert that city police cited appellants for disturbing the
    peace without probable cause because of disagreement with
    the subject-matter of appellants’ speech. Appellants also
    claim that city officials improperly denied sound permits due
    to prior restraint where applications were rejected based on
    appellants’ past non-compliance with permit conditions and
    past violations of the noise ordinance. Finally, appellants
    argue that the district court erred in not granting relief under
    the California Constitution’s broader protections of free
    speech. We affirm the district court.
    4694     ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    I
    Appellants are Christian evangelists who are staff members
    of American Christian Enterprises, a non-profit charity orga-
    nization. Appellant Rosenbaum operates a ministry affiliated
    with the “SOS Ministries” in San Francisco, which conducts
    religious outreach. Since 1978, appellants have preached a
    Christian evangelical message in the streets and parks of San
    Francisco with amplified sound.
    Appellee City of San Francisco (“the City”) has adopted
    under section 47.2 of the San Francisco Police Code (“Police
    Code”) a time, place, and manner restriction that provides,
    inter alia, that “[a]mplified speech and music shall not be
    unreasonably loud, raucous, jarring or disturbing to persons of
    normal sensitiveness.” See S.F.P.C. § 47.2(5). However, indi-
    viduals or groups seeking to use amplified sound that might
    exceed volume levels prohibited under § 47.2 may apply for
    permits under § 43 of the Police Code. Under § 43, the police
    commissioner1 has discretion to issue permits for amplified
    sound for a variety of purposes including public affairs inter-
    ests. Applicants must designate the time, location and purpose
    of the permit, see § 43(c), and are subject to conditions under
    S.F.P.C. §§ 47.2 and 49.2 Denied permits may be contested
    before the head of the Permit Section where public comment
    can be considered, or in an administrative proceeding. Police
    investigations of excessive noise, due to unpermitted amplifi-
    cation, amplification contrary to permit restrictions or volume
    1
    After the time of the relevant conduct in this appeal, the official body
    within the City that adjudicates challenges to denied permits has been re-
    designated as the “Entertainment Commission.” See S.F.P.C. § 43.
    2
    Of concern here is subsection 47.2(7), which provides that amplified
    sound may be halted if it is audible beyond 250 feet of the attendant audi-
    ence. See S.F.P.C. § 47.2(7). Also, section 49 generally prohibits “amplifi-
    cation of sound or human voice in such a manner as to produce raucous
    noises or . . . disturb the peace, quiet and comfort of persons in the neigh-
    borhood or with volume louder than . . . necessary for convenient hear-
    ing.” S.F.P.C. § 49.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        4695
    of amplification, are typically initiated after a citizen com-
    plaint. San Francisco police officers may inquire about unac-
    ceptably loud noise, issue citations and/or arrest the speaker/
    performer if they have probable cause under section 415 of
    the California Penal Code that a user of sound amplification
    intends to “maliciously and willfully” create “loud and unrea-
    sonable noise.” See Cal. Pen. Code § 415.
    For almost three decades, Rosenbaum and Livingston have
    requested and from time to time received numerous permits
    from the City for sound amplification to conduct their out-
    reach. Beginning in late 1995, however, many of appellants’
    permit applications were denied or issued with significant
    restrictions for specific events. In addition, appellants began
    to encounter increasing attention from the San Francisco
    police who, in response to citizen complaints on specified
    occasions, admonished, cited or arrested appellants, or threat-
    ened such sanctions, for not having a necessary permit for
    their amplified sound, for not complying with the limitations
    on their permit, or for using excessively loud amplification.
    On September 19, 1996, appellants filed suit in the United
    States District Court for the Northern District of California
    against the City and County of San Francisco and three city
    officials in their official capacity (collectively “the City”),
    seeking injunctive and declaratory relief. Appellants asserted
    eight claims based on events alleged to have occurred
    between May 28, 1990 and August 9, 1996: (1) “Enjoinment
    of San Francisco Police Code § 47.2 on grounds of vagueness
    and overbreadth”; (2) “Enjoinment of Police Code § 47.2 and
    Penal Code § 415 and unlawful permitting procedures on
    equal protection grounds”; (3) “Enjoinment of enforcement of
    the ‘heckler’s veto’ against plaintiffs”; (4) “Enjoinment of the
    denial of government permits because said denial is a prior
    restraint on the free speech rights of the plaintiffs”; (5) “For
    violation of Title 42 U.S.C. Section 1983”; (6) “For civil con-
    spiracy and for conspiracy to interfere with civil rights in vio-
    lation of 42 U.S.C. section 1985”; (7) “Violation of the
    4696   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    Religious Freedom Restoration Act”; and (8) “Pendent State
    Claim for violation of California Constitution Article I, sec-
    tions 1, 2 and 4.” Thereafter, appellants moved for a prelimi-
    nary injunction to prohibit the City from enforcing § 47.2 of
    the Police Code and § 415 of the California Penal Code. On
    November 8, 1996, the district court denied the preliminary
    injunction, which we upheld on March 26, 1997. See Rosen-
    baum v. City & County of San Francisco, 
    110 F.3d 69
    (9th
    Cir. 1997) (“Rosenbaum I”) (unpublished opinion).
    In January 1998, the City filed the first of two summary
    judgment motions. On June 15, 1998, the district court
    granted partial summary judgment in favor of the City on
    appellants’ First, Sixth and Seventh claims, concluding that
    the amplification restrictions under § 47.2 were facially con-
    stitutional. Appellants did not appeal these rulings. On August
    30, 1999, the district court granted the City’s motion for sum-
    mary judgment on the balance of appellants’ claims. On April
    19, 2001, we reversed, holding that genuine issues of material
    fact remained regarding appellants’ equal protection and First
    Amendment claims. See Rosenbaum v. City & County of San
    Francisco, 8 Fed. Appx. 687 (9th Cir. 2001) (“Rosenbaum
    II”) (unpublished opinion). In reaching this decision with
    respect to the equal protection claims, we relied on facts not
    alleged in the complaint, namely allegations that “small
    groups were allowed to engage in amplified speech activities
    in the same locations for which plaintiffs were denied permits,
    and that other small groups were violating the noise ordi-
    nances in the same manner as plaintiffs but were not cited or
    arrested.” 
    Id. at 691.
    As examples of this alleged conduct, we
    referred to incidents that post-dated the filing of the complaint
    to support our conclusion that “at the summary judgment
    stage, this as well as other evidence in the record . . . suffices
    to raise a genuine issue of material fact as to whether there
    was a ‘policy, plan, or a pervasive pattern’ of misconduct.” 
    Id. at 690.
    On November 6, 2001, appellants moved to amend their
    complaint to substitute defendants and to assert a claim for
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        4697
    damages by Livingston involving similar circumstances.
    Aside from granting the substitution of defendants, the district
    court denied the motion to amend because an additional dam-
    ages claim under new factual allegations was unduly delayed
    and would have prejudiced the City.
    At a bench trial in December of 2002, based on the parties’
    stipulation the district court determined at the outset that the
    following claims remained: (1) an equal protection claim
    based on the manner in which the City issued permits and
    enforced permit requirements for amplified sound; (2) a First
    Amendment claim based on viewpoint discrimination (or
    “heckler’s veto”) in the City’s issuance of permits and
    enforcement of permit requirements; (3) a First Amendment
    claim of prior restraint in the alleged denial of permits based
    on appellants’ past non-compliance with loudspeaker permit
    restrictions; (4) a First Amendment claim based on the City’s
    application of California Penal Code § 415; (5) a claim under
    42 U.S.C. § 1983 based on the above-described alleged con-
    stitutional violations; and (6) a claim under article I, sections
    1, 2 and 4 of the California Constitution, also based on viola-
    tions of rights to free speech and religion.
    Before the district court issued its disposition, appellants
    moved on April 27, 2004 under Federal Rule of Civil Proce-
    dure 15(b) (“Rule 15”) to expand their claims to encompass
    events occurring after the filing of their complaint, which the
    City opposed. In post-trial motions, appellants also sought to
    introduce additional incidents that allegedly occurred as late
    as November 8, 2002. Thus, appellants contended that the
    actionable conduct began as early as May 28, 1990 and con-
    tinued through November 8, 2002.
    The district court issued a Memorandum of Decision on
    January 12, 2005. As a threshold issue, the district court con-
    sidered the issue raised in appellants’ Rule 15 motion whether
    numerous incidents alleged to have occurred between appel-
    lants and the San Francisco police after the August 9, 1996
    4698   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    filing of the complaint could be included within the scope of
    actionable conduct. In particular, appellants had previously
    alleged in a declaration filed in opposition to the City’s
    motion for summary judgment that, beginning on October 11,
    1996 and ending on October 31, 1998, they endured addi-
    tional encounters with the police that resulted in the police
    “shutting down” appellants’ use of unpermitted amplified
    sound, while the police allegedly acquiesced in other
    instances of unpermitted or excessively loud sound amplifica-
    tion by similarly situated loudspeaker users, i.e. small musical
    groups and individual performers in addition to promoters of
    larger events.
    The district court first narrowed the scope of actionable
    conduct under the statute of limitations. The district court
    determined that the appropriate statute of limitations period
    for claims under 42 U.S.C. § 1983 and the California Consti-
    tution was one year because this period paralleled the limita-
    tions period for personal injury suits in California at the time
    of relevant conduct under section 340(3) of the California
    Code of Civil Procedure. See Wilson v. Garcia, 
    471 U.S. 261
    ,
    275-76 (1985) (holding state statute of limitations period for
    personal injury suit applies to constitutional claims under
    § 1983). Under this authority, the district court determined
    that claims based on events prior to September 19, 1995 were
    time-barred.
    As for post-complaint events, the district court first
    observed that in appellants’ November 2001 motion to amend
    the complaint, appellants made no effort to supplement the
    complaint for the purpose of alleging expanded claims based
    on incidents alleged to have occurred after the filing of the
    complaint, and that they waited to move expressly to add fac-
    tual allegations to encompass post-complaint events until
    April 27, 2004. The district court held that under Rule 15 the
    City had neither expressly, nor impliedly, consented to such
    an expansion of claims based on post-complaint factual alle-
    gations. In light of our decision in Rosenbaum II, however,
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO                  4699
    where we held genuine issues of material fact existed as to
    appellants’ constitutional claims in part in reliance on facts
    alleged after the complaint was filed, the district court
    declined to speculate whether we had decided which events fit
    within the scope of conduct under the complaint. Leaving the
    question unanswered, the district court addressed appellants’
    claims first based solely on alleged conduct between Septem-
    ber 19, 1995 and August 9, 1996, and in the alternative, based
    on alleged post-complaint conduct included in appellants’
    opposition to the City’s motion for summary judgment that
    we considered in Rosenbaum II. In any event, the district
    court considered evidence of all incidents, irrespective of date
    of occurrence, to the extent it bore on any alleged pattern or
    policy of police misconduct.
    Under both the narrow and the expanded scope of conduct
    as described above, the district court rejected all appellants’
    claims. This timely appeal followed.
    II
    We first address what conduct may be considered action-
    able under the complaint. The City seeks to limit the scope of
    actionable conduct to events that transpired between Septem-
    ber 1995 and September 1996 based on the district court’s rul-
    ings on the statute of limitations and the denial of appellants’
    motion on April 27, 2004 under Rule 15(b).3 In their reply
    3
    The City argues first that we should not pass on this question because
    appellants waived these issues by not challenging either the statute of limi-
    tations ruling or the Rule 15(b) ruling in their opening appellate brief.
    “[W]e will not ordinarily consider matters on appeal that are not specifi-
    cally and distinctly argued in appellant’s opening brief” unless one of
    three exceptions applies: (1) “for good cause shown,” (2) when the issue
    “is raised in the appellee’s brief,” or (3) “if the failure to raise the issue
    properly did not prejudice the defense of the opposing party.” See Koerner
    v. Grigas, 
    328 F.3d 1039
    , 1048-49 (9th Cir. 2003) (internal quotation
    marks and citation omitted). Here, although the appellants initially did not
    contest the district court’s rulings on these matters, the City raised the
    scope of conduct issue in its brief and the appellants responded in their
    reply brief. Accordingly, we exercise discretion to address the issue.
    4700   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    brief, appellants contend that the district court erred in deny-
    ing the April 27, 2004 motion and limiting the scope of
    actionable conduct to events that occurred before the filing of
    the complaint because we considered post-complaint events in
    Rosenbaum II.
    We review the district court’s order denying a Rule 15(b)
    motion to amend the complaint to conform the pleadings to
    the evidence for an abuse of discretion. See Madeja v. Olym-
    pic Packers, LLC, 
    310 F.3d 628
    , 635 (9th Cir. 2002).
    Rule 15(b) provides in pertinent part:
    When issues not raised by the pleadings are tried by
    express or implied consent of the parties, they shall
    be treated in all respects as if they had been raised
    in the pleadings. Such amendment of the pleadings
    as may be necessary to cause them to conform to the
    evidence and to raise these issues may be made upon
    motion of any party at any time, even after judg-
    ment; but failure so to amend does not affect the
    result of the trial of these issues.
    See Fed. R. Civ. P. 15(b); see also Idaho Plumbers and Pipe-
    fitters Health and Welfare Fund v. Mechanical Contractors,
    Inc., 
    875 F.2d 212
    , 214-15 (9th Cir. 1989) (“We treat issues
    tried by the express or implied consent of the parties as raised
    in the pleadings, even if the parties made no formal amend-
    ment.”).
    In Patelco Credit Union v. Sahni, we rejected the argument
    that certain evidence adduced at trial without objection effec-
    tively amended the defendant’s answer to include a statute of
    limitations defense. 
    262 F.3d 897
    , 907 (9th Cir. 2001). “While
    it is true that a party’s failure to object to evidence regarding
    an unpleaded issue may be evidence of implied consent to a
    trial of the issue, it must appear that the party understood the
    evidence was introduced to prove the unpleaded issue.” 
    Id. ROSENBAUM v.
    CITY AND COUNTY OF SAN FRANCISCO              4701
    (internal quotation marks omitted); see also Consol. Data
    Terminals v. Applied Digital Data Sys., Inc., 
    708 F.2d 385
    ,
    396 (9th Cir. 1983) (“An adverse party cannot be expected to
    object to the introduction of evidence that is only tangentially
    related to the issues actually pleaded prior to trial unless the
    party has notice that the evidence is being introduced as proof
    on some other unpleaded issue.”).
    [1] Here, the district court did not abuse its discretion in
    concluding that the City had not impliedly consented to try
    appellants’ claims based on post-complaint conduct simply
    because the City referred to events in 1997 and 1998 in
    responding to appellants’ opposition to summary judgment.
    As the district court correctly found, the thrust of the City’s
    motion for summary judgment pertained to its argument that
    Livingston and Rosenbaum lacked standing to assert claims
    for injunctive relief because they could not demonstrate a
    threat of future harm where “over a three year period, plain-
    tiffs obtained loudspeaker permits for at least seventy-eight
    events; during 1998 alone, plaintiff received permits for
    twenty-five events.” See Def. Mot. for Summ. J., Nov. 16,
    1998, at 11. To the extent appellants referenced post-
    complaint events in their opposition to summary judgment,
    the district court concluded that such additional factual allega-
    tions “reasonably would have been understood . . . to be in
    response to the City’s argument.” Also, the City objected at
    trial to any evidence referring to post-complaint events as
    irrelevant, and the district court permitted the evidence only
    for the limited purpose of showing a pattern or practice of dis-
    crimination required for injunctive relief. The district court
    did not abuse its discretion under Patelco Credit because
    there was no indication that appellants introduced the numer-
    ous post-complaint events for any purpose other than to refute
    the City’s claim of insufficient threat of future harm in light
    of its assertion that permits had been issued to appellants dur-
    ing 1998.4
    4
    Our decision in Rosenbaum II viewed in context reinforces the district
    court’s conclusion. When we referred to Livingston’s arrest on February
    4702     ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    [2] Because appellants do not explicitly contest the district
    court’s proper statute of limitations ruling, the scope of
    actionable conduct begins with events that occurred as of Sep-
    tember 1995. Because the district court did not abuse its dis-
    cretion in narrowing the scope of actionable conduct to events
    alleged in the complaint, we do not consider events after Sep-
    tember 19, 1996, except as relevant to any alleged policy or
    pattern of police misconduct that would warrant injunctive
    relief.
    III
    We review constitutional issues de novo. See Buono v. Nor-
    ton, 
    371 F.3d 543
    , 548 (9th Cir. 2004). A district court’s
    determinations on mixed questions of law and fact that impli-
    cate constitutional issues are similarly reviewed de novo.
    Cogswell v. City of Seattle, 
    347 F.3d 809
    , 813 (9th Cir. 2003).
    Where, however, the application of the law to the facts
    requires an inquiry that is “essentially factual,” we review for
    clear error, see Zivkovic v. S. Cal. Edison Co., 
    302 F.3d 1080
    ,
    1088 (9th Cir. 2002), with exception of issues arising under
    the First Amendment, where we conduct an independent
    review of the facts. See Tucker v. California Dep’t of Educ.,
    
    97 F.3d 1204
    , 1209 n.2 (9th Cir. 1996).
    IV
    In their equal protection challenge under the Fourteenth
    Amendment, Rosenbaum and Livingston assert: (1) that they
    were denied permits where similarly situated applicants
    22, 1997, and to several permit denials between March 14, 1997 and Sep-
    tember 16, 1997, we did so to support our conclusion that the district court
    erroneously granted summary judgment where these alleged post-
    complaint events created genuine issues of material fact in regard to the
    issue whether the City exhibited a policy or pervasive pattern of improper
    selective enforcement that might warrant injunctive relief. See Rosenbaum
    II, 8 Fed. Appx. at 690.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO                4703
    received permits; (2) that, irrespective of whether they
    received a permit for sound amplification, the City police
    “shut down” their amplified speech whereas other similarly
    situated groups (mainly street musicians), permitted or not,
    were left unmolested to engage in sound amplification.
    A government entity has discretion in prosecuting its crimi-
    nal laws, but enforcement is subject to constitutional con-
    straints. See Wayte v. United States, 
    470 U.S. 598
    , 608 (1985).5
    To prevail on its claim under the equal protection clause of
    the Fourteenth Amendment, a plaintiff must demonstrate that
    enforcement had a discriminatory effect and the police were
    motivated by a discriminatory purpose. 
    Id. at 608.
    “To estab-
    lish a discriminatory effect . . . , the claimant must show that
    similarly situated individuals . . . were not prosecuted.”
    United States v. Armstrong, 
    517 U.S. 456
    , 465 (1996). To
    show discriminatory purpose, a plaintiff must establish that
    “the decision-maker . . . selected or reaffirmed a particular
    course of action at least in part ‘because of,’ not merely ‘in
    spite of,’ its adverse effects upon an identifiable group.”
    
    Wayte, 470 U.S. at 610
    (internal citation omitted).
    In addition to the showing of discriminatory purpose and

    A
    As for appellants’ argument urging that there was selective
    issuance of permits, appellants alleged in their complaint the
    following instances within the statute of limitations period
    where they were either denied a permit or issued a permit
    with restrictions: (1) In February 1996, the City granted two
    permits for the intersection of Fifth and Market Streets, with
    the restriction that the speaker be turned away from Market
    Street; and in March 1996, the City denied Livingston four
    permit applications for the same intersection. (2) On April 26,
    1996, appellants were denied three permits requested for May
    4, 11 and 25, 1996 at the corner of Fifth and Market Streets
    and a resubmitted request for 989 Market Street. (3) On July
    1, 1996, appellants received permits for July 20 and August
    17, 1996 at 835 Market Street, with the limitation that appel-
    lants could not use more than two loudspeakers of no more
    than 50-watt capacity each.
    [3] “The first step in equal protection analysis is to identify
    the [city’s] classification of groups. . . . Once the plaintiff
    establishes governmental classification, it is necessary to
    identify a ‘similarly situated’ class against which the plain-
    tiff’s class can be compared.” Freeman v. City of Santa Ana,
    
    68 F.3d 1180
    , 1187 (9th Cir. 1995) (internal quotation marks
    omitted). Appellants argue that the district court erroneously
    rejected appellants’ alleged control group—any group or indi-
    vidual, permitted or non-permitted, that appellants observed
    using amplified sound.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO       4705
    [4] Appellants’ control group theory is unconvincing. In
    their focus on selective enforcement, appellants appear not to
    recognize the district court’s distinction between its analysis
    of alleged equal protection violations based respectively on
    permit issuance and permit enforcement. Appellants in their
    complaint refer only to large permitted events that apparently
    were allowed to continue despite excessive volume and some
    noise complaints by appellants—the Cinco de Mayo Celebra-
    tion on May 5, 1996; the “KFOG Sky Concert” on May 11,
    1996; the “Making Waves” musical heritage festival on June
    21, 1996; and the Gay Pride Celebration on June 30, 1996. As
    for permit issuance, the district court correctly held that a
    proper control group would have been smaller groups that
    applied for permits for sound amplification at similar times
    and locations. By contrast, appellants’ undifferentiated control
    group of permitted and non-permitted groups, large and small,
    using amplified sound was not comparable because these
    groups were not similarly situated because of their varying
    characteristics. Because appellants did not identify a bona fide
    control group, they cannot demonstrate a discriminatory effect
    in the City’s issuance of permits for amplified sound.
    B
    As for appellants’ argument that they were shut down while
    others were unmolested in selective enforcement of S.F.P.C.
    § 47.2, appellants alleged in their complaint that the City
    police in some manner “shut down” appellants’ use of ampli-
    fied sound on six occasions: (1) On February 2, 1996, at 9:00
    p.m., the police stopped appellants’ use of their 9-watt “maxi
    mouse” amplifier at Haight and Ashbury Streets based on an
    alleged violation of the noise ordinance. (2) On March 9,
    1996, at 12:15 p.m., Livingston was cited for a noise violation
    under S.F.P.C. § 47.2 and the outreach rally that had received
    a permit was discontinued because the investigating officer
    purportedly could hear the sound from over 250 feet of the
    attendant audience. (3) On March 29, 1996, at 9:45 p.m. at
    Haight and Masonic Streets, the police stopped the unpermit-
    4706   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    ted use of the “maxi mouse” amplifier in response to a citizen
    complaint and threatened to arrest Livingston if the unpermit-
    ted activity continued. (4) Similarly, on April 13, 1996, at
    5:00 p.m. at Clement and Tenth Streets, two officers threat-
    ened to cite appellants for excessive sound during unpermitted
    activity. (5) On August 2, 1996, Rosenbaum was cited for
    excessive noise during unpermitted use of the “maxi mouse”
    amplifier in response to a citizen complaint where the com-
    plainant supposedly had been heckling Rosenbaum before-
    hand. (6) On August 9, 1996, at 9:25 p.m. on Broadway and
    Columbus Streets, Livingston was arrested for violating
    S.F.P.C. § 47.2 and § 415 of the California Penal Code.
    Appellants argue that the district court erred in adjudicating
    their equal protection claims by not acknowledging similarly
    situated groups—“small un-permitted groups . . . allowed to
    engage in amplified speech activities”—and by requiring that
    appellants prove that the City had a discriminatory intent.
    Both theories are unavailing.
    Appellants’ first argument is not supported by the district
    court’s actual finding. The district court stated that “various
    street musicians and other entertainers whom plaintiffs
    observed using amplified sound . . . without police interfer-
    ence . . . [were] comparable for purposes of equal protection
    analysis.” (emphasis added). In regard to identifying the con-
    trol group for purposes of selective enforcement, the district
    court did not err. Appellants’ claim that the district court erred
    in applying the wrong legal standard, namely that the City
    was motivated by a “discriminatory intent,” is similarly belied
    by the district court’s emphasis on the discriminatory effect
    and purpose test in Wayte, 
    470 U.S. 598
    , and its conclusion
    that appellants did not establish that the City engaged in “pur-
    poseful discrimination based on the content of plaintiffs’ mes-
    sage.” The district court correctly identified the proper control
    group and applied the correct legal standard for selective
    enforcement analysis.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        4707
    [5] To the extent appellants claim an equal protection viola-
    tion because large, permitted events were allowed to continue
    despite noise complaints, whereas appellants’ activities were
    restricted or terminated in some manner in response to com-
    plaints, this claim, too, is unavailing. The district court cred-
    ited evidence introduced by the City that two different
    divisions of the San Francisco Police Department are charged
    with permit issuance and enforcement of the municipal noise
    ordinances respectively, each with distinct standards and
    objectives: permits are issued in light of time, place and man-
    ner criteria whereas permit enforcement is complaint-based.
    Aside from anecdotal testimony by Rosenbaum and Living-
    ston that they complained about “loud” music featured at
    these larger events, appellants did not produce evidence
    regarding restrictions on these permits, or whether these
    permit-holders violated any conditions of their respective per-
    mits. Without proof of permit violation, the fact that appel-
    lants may have complained without police response is not
    dispositive of any discriminatory effect. Moreover, the fact
    that officers “shut down” appellants’ four instances of unper-
    mitted activity based on citizen complaints does not reflect
    discriminatory enforcement because the police may legiti-
    mately respond to citizen complaints and stop excessive
    amplified sound, especially if unpermitted, under S.F.P.C.
    §§ 43, 47.2, and 49. In light of these distinct noise enforce-
    ment modes, and the differences in event size, the district
    court permissibly could conclude that the City did not engage
    in a pattern of selective noise ordinance enforcement based on
    the conduct alleged in the complaint.
    [6] An examination of the events alleged to have occurred
    post-complaint also does not reveal any pattern of discrimina-
    tory noise ordinance enforcement aimed at appellants. To
    conclude that such a pattern existed, appellants would have to
    present evidence of a pervasive policy of selective enforce-
    ment with respect to the control group of individuals or small
    groups engaged in unpermitted sound amplification.
    4708     ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    In addition to showing that officers within the agency have
    engaged in a persistent pattern of misconduct, see 
    Hannigan, 92 F.3d at 1500
    , “[l]iability may attach to a municipality only
    where the municipality itself causes the constitutional viola-
    tion through ‘execution of a government’s policy or custom,
    whether made by its lawmakers or by those whose edicts or
    acts may fairly be said to represent official policy.’ ” Ulrich
    v. City and County of San Francisco, 
    308 F.3d 968
    , 984 (9th
    Cir. 2002) (quoting Monell v. Dep’t of Soc. Serv., 
    436 U.S. 658
    , 694 (1978)). In a Monell claim, there are three ways to
    show a policy or custom of a municipality: (1) by showing “a
    longstanding practice or custom which constitutes the ‘stan-
    dard operating procedure’ of the local government entity”; (2)
    “by showing that the decision-making official was, as a matter
    of state law, a final policymaking authority whose edicts or
    acts may fairly be said to represent official policy in the area
    of decision”; or (3) “by showing that an official with final
    policymaking authority either delegated that authority to, or
    ratified the decision of, a subordinate.” 
    Ulrich, 308 F.3d at 984-85
    (internal quotation marks and citations omitted).
    The district court found that there was no discriminatory
    effect on the following evidence: (1) Appellants’ “maxi-
    mouse” loudspeaker required a permit, which the police only
    irregularly enforced against the appellants and similarly situ-
    ated musicians and performers. (2) Under the expanded chro-
    nology of reviewable events, the district court addressed a
    variety of musical groups who were, with one exception,6
    playing without permits at different times and places than appel-
    lants.7 (3) Police asked appellants to turn down their loud-
    6
    The exception concerned only one incident where appellants’ non-
    permitted activities prompted an admonishment, but a performer named
    Emerson did not receive a similar warning, among the four incidents
    where appellants’ and Emerson’s activities coincided at Taylor and Jeffer-
    son Streets from the afternoon to early evening hours on February 8 and
    22, 1997, March 22, 1997, and April 12, 1997. The district court ruled that
    appellants did not prove discriminatory effect based on a single incident.
    7
    The district court determined that appellants were told by police to stop
    preaching with amplified sound or to turn down the volume on the follow-
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO              4709
    speaker at Fisherman’s Wharf when no other similarly
    situated groups were playing music. Under these findings, the
    evidence suggests no pattern of selective enforcement.
    In regard to discriminatory effect, it must be first recog-
    nized as a general matter that during the approximate seven-
    year period covered under the complaint and afterward, appel-
    lants were often unmolested in using sound equipment to
    preach the Christian gospel, whether their activities were per-
    mitted or not.8 According to Livingston’s own testimony,
    appellants were able to perform on many occasions from 1995
    to 1997 in well-populated San Francisco neighborhoods using
    a 9-watt “maxi-mouse” amplifier without police interference.
    This admission suggests that appellants were regularly
    allowed to preach using non-permitted sound amplification.
    Evidence relied on by appellants also supports this conclu-
    sion. For instance, appellants point to incidents on June 1 and
    November 6, 1999, at Powell and Market Streets, where
    appellants complained about a small protest group using a 10-
    watt loudspeaker without a permit, but the police allowed the
    protest to continue. Appellants contend that this type of post-
    complaint police inaction showed the City’s pattern of selec-
    tive enforcement; however, when viewed in light of appel-
    lants’ own admission that they also were regularly allowed to
    continue unpermitted activity, their claim of selective enforce-
    ment is undercut. Second, in the vast majority of instances,
    ing dates and locations: October 11, 1997 at 9:40 p.m. at Broadway and
    Columbus Avenue; January 9, 1997 at 5:20 p.m. on Haight Street near
    Ashbury Street; February 22, 1997 at 7:00 p.m. on Market Street near
    Grand Avenue; and June 26, 1998 at 9:30 p.m. at Taylor and Jefferson
    Streets.
    8
    In support of the conclusion that there was a general acceptance of
    appellants’ ministries in San Francisco, the City issued nine permits in
    October-December 1995; fifteen permits in 1996; twenty-five permits in
    1997; twenty-six permits in 1998; three permits in 1999; forty-seven per-
    mits in 2000; forty-four permits in 2001, and thirty-one permits in 2002.
    4710     ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    appellants made no showing that they were using amplified
    sound at the same time and/or location as comparable perform-
    ers.9
    [7] As for discriminatory purpose, the City produced evi-
    dence that police were responding to citizen complaints or
    were alerted to appellants’ illegal activities (whether permit-
    ted or not) because of the excessive noise. Evidence at trial
    revealed only a few occasions where appellants were using
    amplified sound and complained about other small groups
    also engaged in sound amplification in the same vicinity. For
    example, appellants claim that on August 6, 1996 the police
    failed to cite Reckless Records, a record store that purportedly
    played loud music to disturb plaintiffs. While it is true that
    police issued no citation, police did admonish the record store
    and ordered it to turn down the music. Moreover, in the single
    post-complaint incident where appellants were preaching
    without permitted sound amplification at the same time and
    location as the performer Emerson, police ordered appellants
    to stop on one occasion but took no action against Emerson
    because he was not playing when police arrived.10 Appellants’
    claim that police should have remained on the scene due to a
    likelihood that Emerson would play again is unreasonable
    given the low law enforcement priority at issue.
    9
    For instance, appellants cite the testimony of Carl Friedrich, a business
    manager at Pier 41, who stated that between 1991 and 1997 he complained
    approximately twenty times that rock music was being played, but no
    police arrived. However, the potency of this testimony with respect to the
    claimed discriminatory effect is substantially weakened by the fact that
    appellants did not allege that they also were active at Pier 41 on these
    occasions.
    10
    Appellants claim that the district court improperly disregarded two
    other incidents of alleged disparate treatment involving their use of ampli-
    fied speech coincident with Emerson’s street performances, on June 26,
    1998 and January 19, 2001, where appellants were “shut down” but Emer-
    son was purportedly allowed to continue. The district court did not commit
    clear error in dismissing the significance of these incidents because there
    was insufficient evidence that Emerson was playing when the police
    arrived.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO                   4711
    [8] Appellants’ claimed acts of selective enforcement did
    not have a discriminatory effect. There was likewise no evi-
    dence to suggest that any action or non-action by the police
    was taken “because of . . . its adverse effects upon [the] iden-
    tifiable group.”11 
    Wayte, 470 U.S. at 610
    . Even if we were to
    credit the few instances of arguable non-enforcement against
    similarly situated groups, a pattern or policy of discrimination
    is not established by these few instances over the entire period
    where appellants frequently conducted outreach with both
    permitted and unpermitted amplified sound, and police have
    discretion to determine the appropriate level of enforcement.
    See 
    Hannigan, 92 F.3d at 1500
    (requiring plaintiffs to estab-
    lish more the repeated incidents of misconduct sufficient for
    injunctive relief). Appellants’ claim for injunctive relief is
    also flawed because of a lack of evidence that the City had a
    standard operating procedure or policy directed by an official
    with final policy-making authority. See 
    Ulrich, 308 F.3d at 984-85
    . We affirm the district court in denying appellants’
    equal protection claims.
    V
    Appellants advance three main theories in claiming that the
    City engaged in viewpoint discrimination in violation of the
    First Amendment. First, appellants argue that the City gave
    effect to an improper “heckler’s veto” when officers
    11
    Due to the absence of a discriminatory effect or purpose, appellants’
    claim that the district erred in not applying strict scrutiny is meritless.
    Strict scrutiny only applies once a law is determined to be discriminatory.
    See Doe v. Kamehameha Schools/Bernice Pauahi Bishop Estate, 
    470 F.3d 827
    , 837-39 (9th Cir. 2006) (discussing type and nature of discrimination
    that triggers strict scrutiny review). Likewise, appellants’ assertion that the
    district court improperly applied rational basis review is also baseless. The
    district court made passing reference to “rational basis” only to reject any
    implied equal protection claim that the permitting ordinance was passed
    to discriminate against appellants as a discrete class. See Village of Wil-
    lowbrook v. Olech, 
    528 U.S. 562
    (2000) (recognizing equal protection vio-
    lation where ordinance is targeted at single individual because state action
    is arbitrary and irrational).
    4712    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    responded to noise complaints initiated by citizens who dis-
    agreed with the content of appellants’ Christian message.
    Appellants contend that the district court erred in examining
    the enforcing officer’s state of mind to reject discriminatory
    intent. Second, appellants contend that the district court erred
    in rejecting viewpoint discrimination because the City exer-
    cised unbridled discretion in issuing permits and because the
    City used the grounds of excessive volume as a pretext for
    denying loudspeaker permits where the actual basis was the
    content of appellants’ Christian message. Third, appellants
    argue that the district court erred in finding probable cause to
    arrest appellants under California Penal Code § 415 for “dis-
    turbing the peace,” where the motivation implied was dis-
    agreement with the content of appellants’ speech.
    “Discrimination against speech because of its message is
    presumed to be unconstitutional.” Rosenberger v. Rector &
    Visitors of the Univ. of Va., 
    515 U.S. 819
    , 828 (1995). Sec-
    tions 43 and 47.2 of the San Francisco Police Code, which
    jointly comprise the statutory framework governing eligibility
    for loudspeaker permits, are facially valid as a content-neutral
    time, place, and manner restriction.12 See Faith Ctr. Church
    Evangelistic Ministries v. Glover, No. 05-16132, 
    2007 WL 703599
    , at *12 (9th Cir. Mar. 9, 2007) (“Content-neutral
    restrictions that regulate the time, place, and manner of
    speech are permissible so long as they are ‘narrowly tailored
    to serve a significant government interest, and [they] leave

    ation in the original) (quoting Perry Educ. Ass’n v. Perry
    Local Educators’ Ass’n, 
    460 U.S. 37
    , 45 (1983)). Despite the
    neutral content of a statute on its face, however, a statute as-
    applied may be constitutionally infirm if its enforcement is
    based on viewpoint discrimination. See Kuba v. 1-A Agric.

    (alteration in the original) (quoting Perry Educ.

    (Brennan, J., dissenting)). It should be underscored,
    however, that “[a] regulation that serves purposes unrelated to
    the content of expression is deemed neutral, even if it has an
    incidental effect on some speakers or messages but not oth-
    ers.” Ward v. Rock against Racism,

    Appellants argue that the City applied an improper “heck-
    ler’s veto” when, in regulating amplified speech under
    S.F.P.C. § 47.2, police officers responded to complaints by
    citizens who disagreed with the content of appellants’ Chris-
    tian message.
    [9] A “heckler’s veto” is an impermissible content-based
    speech restriction where the speaker is silenced due to an
    anticipated disorderly or violent reaction of the audience. See
    Brown v. Louisiana, 
    383 U.S. 131
    , 133 n.1 (1966); see also
    Forsyth County v. Nationalist Movement, 
    505 U.S. 123
    , 137
    (1992) (invalidating ordinance that allowed county adminis-
    trator to adjust parade permit fees based on anticipated cost of
    security). In Forsyth County, Chief Justice Rehnquist pointed
    to the risk of a “heckler’s veto” where a permittee might be
    subject to higher fees because of higher security costs associ-
    ated with a hostile crowd. 
    Id. at 142
    (Rehnquist, J., dissent-
    ing).
    4714   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    [10] Appellants’ “heckler’s veto” claim here is miscon-
    ceived. The district court concluded that the City’s permitting
    procedures and enforcement criteria were not motivated by
    fear of any hostile or unruly reaction by citizens who com-
    plained about appellants’ activities. Testimony at trial indi-
    cated only two incidents within the scope of actionable
    conduct where citizen complainants may have responded to
    appellants’ Christian message when making noise complaints:
    (1) On August 2, 1996, a complainant allegedly yelled at
    appellants that “Christians are child molesters,” before lodg-
    ing a complaint that appellants were disturbing the peace. (2)
    On August 9, 1996, a complainant purportedly argued with
    SOS Ministries members and expressed anti-Christian views
    prior to calling the police. As to these specific exchanges
    between appellants and citizen complainants, appellants do
    not allege whether any complainant mentioned any anti-
    Christian sentiments when filing the complaint. Moreover, to
    follow appellants’ logic and impute the view of the complain-
    ant to the investigating officer would lead to an absurd result:
    In the event a bystander was provoked by the content of a par-
    ticular message and complained, the speaker could theoreti-
    cally amplify that message at an intolerable volume with
    impunity because the enforcement of the complaint would
    automatically be transformed into a First Amendment viola-
    tion. As such, we reject appellants’ theory. Absent some gen-
    uine nexus between a complainant’s subject-matter
    disagreement and the basis for the investigation of the com-
    plaint by authorities, appellants cannot prevail on a “heckler’s
    veto” claim of viewpoint discrimination.
    [11] Here, the district court’s findings after bench trial
    rejected such a nexus. The district court found the testimony
    of the responding officers to be credible that they were
    responding only to noise complaints. The district court cor-
    rectly concluded that there was no “heckler’s veto” because
    appellants did not demonstrate with any evidence that the San
    Francisco police officers who responded to these specific inci-
    dents, or any incidents more generally, knew about, agreed
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        4715
    with or adopted any views of the complainants. To the con-
    trary, the record is clear that officers responding to these two
    incidents instructed appellants to lower the volume, which
    would have allowed appellants to express their Christian
    views; when they refused, however, the officers were again
    dispatched to control the unreasonably loud speech in
    response to citizen complaints. The district court also credited
    police officer testimony that when appellants were told to stop
    the non-permitted amplified speech that was excessively loud,
    investigating officers regularly informed appellants that they
    could continue to preach, albeit without amplification. This
    reinforces the conclusion that the City was concerned about
    unacceptable noise levels and not with the content of appel-
    lants’ Christian message.
    B
    Appellants claim that the district court erred in not address-
    ing their claim of unbridled discretion, which appellants con-
    tend allowed the City to engage in viewpoint discrimination.
    Appellants also contend that because no volume specification
    was called for on permit applications, evidence that police
    officers were responding to excessive noise is pretextual and
    betrays viewpoint discrimination.
    [12] “The principal inquiry in determining content neutral-
    ity, in speech cases generally and in time, place, or manner
    cases in particular, is whether the government has adopted a
    regulation of speech because of disagreement with the mes-
    sage it conveys.” 
    Ward, 491 U.S. at 791
    . An ordinance that
    affords city officials unbridled discretion to determine
    whether or not to enforce limitations on First Amendment
    activity may support the inference of viewpoint discrimina-
    tion. See City of Lakewood v. Plain Dealer Publ’g Co., 
    486 U.S. 750
    , 757 (1988). As noted above, however, “[a] regula-
    tion that serves purposes unrelated to the content of expres-
    sion is deemed neutral, even if it has an incidental effect on
    4716   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    some speakers or messages but not others.” 
    Ward, 491 U.S. at 791
    .
    In pressing their theory that the City fell prey to viewpoint
    discrimination due to its alleged exercise of unbridled discre-
    tion, appellants rely on our decision in American Jewish
    Cong. v. City of Beverly Hills, 
    90 F.3d 379
    (9th Cir. 1996).
    In that case, we considered a claim under the Establishment
    Clause of the First Amendment where defendant city gener-
    ally proscribed erection of unattended displays on public
    property, with a single exception that permitted the presence
    of a 27-foot menorah during the Chanukah season. 
    Id. at 380-
    81. When the city denied permits to two applicants, who were
    respectively seeking to create a “winter solstice” scene and
    plant a Latin cross on public property, we concluded that the
    unique exception to allow the menorah violated the Establish-
    ment Clause because it demonstrated a preference for the
    Jewish religion, see 
    id. at 383,
    and because the ordinance
    vested city officials with unbridled discretion. 
    Id. at 384
    (“The City may not have a general policy banning unattended
    private displays, but, on an ad hoc basis with no standards to
    guide it, choose one religious group and permit it to erect a
    display while denying all other groups permission to erect dis-
    plays.”). In American Jewish Congress, we held that the “ad
    hoc and structureless nature of the City’s permitting process
    leaves open the possibility of improper discrimination by the
    City.” 
    Id. at 385.
    [13] Contrary to appellants’ contentions, under S.F.P.C.
    § 43, the police commissioner has guided discretion to issue
    permits for amplified sound for a variety of purposes includ-
    ing public affairs interests. Applicants must designate time,
    location and purpose of the permit, see § 43(c), and are
    expressly subject to conditions under S.F.P.C. §§ 47.2 and 49.
    Section 47.2 prohibits amplified sound from being “unreason-
    ably loud [and] raucous” and sets forth the temporal restric-
    tion that amplified sound is permitted only between 9:00 a.m.
    and 10:00 p.m. and the spatial restriction that amplified sound
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO          4717
    cannot be audible from 250 feet of the broadcast area. See
    S.F.P.C. §§ 47.2(2), (5) and (7). In pertinent part, § 49 also
    prohibits “amplification of sound or human voice in such a
    manner as to produce raucous noises or . . . disturb the peace,
    quiet and comfort of persons in the neighborhood or with vol-
    ume louder than . . . necessary for convenient hearing.” See
    S.F.P.C. § 49.
    [14] In denying appellants permits, the City based its deci-
    sion on the fact that the proposed use of amplified sound was
    unsuitable for the area covered by the requested permit under
    several statutory criteria. For instance, in the Notice of Deci-
    sion on May 23, 1996 denying appellants’ permit application,
    the hearing officer noted citizens’ complaints that they were
    being subjected to excessive volumes that disrupted busi-
    nesses during the day and disturbed residents with children in
    the evening because of the unreasonably loud volume. The
    hearing officer also cited repeated direct requests by citizens
    to Livingston and Rosenbaum to reduce their sound levels.
    Moreover, the hearing officer credited police statements that
    appellants routinely could be heard at a distance of more than
    250 feet from the sound source. Finally, the hearing officer
    found that appellants were often unwilling to reach an accom-
    modation with these area residents. As such, the City hearing
    officer denied the permit application because people near the
    proposed gatherings were being “subjected to unreasonably
    loud music and human speech.” See Notice of Decision, May
    23, 1996. Appellants adduced no evidence that City officials
    were otherwise motivated in denying permits. Finally, as dis-
    cussed in the context of appellants’ equal protection claim, the
    charge of unbridled discretion is weakened by the fact that on
    many occasions they applied for and received permits at this
    and other sites.13
    13
    The City issued nine permits in October-December 1995 and fifteen
    permits in 1996.
    4718   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    Appellants also assert a claim of pretext that the police rou-
    tinely requested or forced appellants to cease their permitted
    amplified speech based on excessive noise, although, accord-
    ing to appellants, the City had no grounds to do so because
    appellants never requested a particular volume level when
    applying for a permit. As an initial matter, this factual claim
    is inaccurate because permits issued under S.F.P.C. § 47(a)(9)
    are subject to the requirement that applicants indicate “maxi-
    mum sound-producing power” in terms of specific wattage for
    the loudspeaker to be used, see S.F.P.C. § 47(a)(9), and the
    record contains numerous permit applications that uniformly
    request that the applicant indicate a specific wattage. Appel-
    lants’ argument here suffers from lacking specificity since
    they have not cited to any particular permit where they did not
    indicate a volume level. More importantly, whether permitted
    or not, users of amplified sound are subject to general regula-
    tions that “amplified human speech . . . shall not be unreason-
    ably loud, raucous, jarring or disturbing to persons of normal
    sensitiveness within the area of audibility.” S.F.P.C.
    § 47.2(5), unless specifically granted permission otherwise
    (e.g. for larger events). This evidence defeats appellants’
    claim of pretext.
    [15] Because §§ 47 and 47.2 condition both the issuance of
    sound permits and the use of sound amplification, it is evident
    that the City did not have unbridled discretion. The Notices
    of Decision during the relevant period provide content-neutral
    justifications for appellants’ denied permits, and appellants do
    not facially attack the governing framework for permit issu-
    ance under S.F.P.C. §§ 43, 47 and 47.2.
    C
    Appellants’ third theory of viewpoint discrimination is that
    the City made no legitimate showing of probable cause when
    citing Livingston and Rosenbaum under California Penal
    Code § 415 for “maliciously and willfully” disturbing others.
    The absence of probable cause, continues appellants’ argu-
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO                4719
    ment, demonstrates that the City sought to suppress appel-
    lants’ religious message.14
    [16] California Penal Code § 415 provides in pertinent part
    that “[a]ny person shall be punished . . . who maliciously and
    willfully disturbs another person by loud and unreasonable
    noise.” Cal. Pen. Code § 415(2). As the district court found,
    “[t]he words ‘malice’ and ‘maliciously’ import a wish to vex,
    annoy, or injure another person, or an intent to do a wrongful
    act, established either by proof or presumption of law.” See
    Cal. Pen. Code § 7. In In re Brown, the California Supreme
    Court clarified the meaning of willful disturbance: “The use
    of the human voice to disturb others by the mere volume of
    the sound when there is no substantial effort to communicate
    or when the seeming communication is used as a guise to
    accomplish the disruption may be prohibited [under § 415].”
    
    9 Cal. 3d 612
    , 621 (1973). Although the California Supreme
    Court concluded in that case that anti-war protesters who car-
    ried picket signs, shouted obscenities, and shook their fists at
    riot police could not be arrested under § 415 because their
    actions did not pose a clear and present danger of inciting oth-
    ers to violence, the holding was not absolute such “that sec-
    tion 415 may never be applied to loud shouting and cheering.”
    
    Id. [17] In
    Knox v. Southwest Airlines, we recognized the con-
    stitutional principle that “[t]he First Amendment does not pre-
    vent enforcement of disorderly conduct statutes so long as
    they are not vague or applied to curb protected speech.”

    We review the district court’s finding of probable cause de novo, see
    United States v. Nava, 
    363 F.3d 942
    , 944 (9th Cir. 2004); however, histor-
    ical facts are reviewed for clear error. See United States v. Vesikuru, 
    314 F.3d 1116
    , 1122 (9th Cir. 2002).
    4720   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    Here, appellants alleged in their complaint two separate
    incidents where they contend that they were cited under § 415
    without probable cause. The district court made the following
    findings about the incidents:
    At the time of the citation [on August 2, 1996],
    plaintiff Rosenbaum was using amplified sound in a
    mixed residential/commercial neighborhood after
    9:00 p.m. He did not have a permit to use amplified
    sound. Officer Mark Landon, a police officer on
    vehicle patrol, heard the sound from a block away
    with his windows closed, responded and asked
    Rosenbaum to turn the sound down. Approximately
    fifteen minutes later, Officer Landon was dispatched
    on a noise complaint, at which time the complainant,
    Joe Narvik, signed a citizen’s arrest card. Narvik
    reported that Rosenbaum was keeping his children
    awake and had refused to turn the sound down when
    Narvik requested that he do so.
    At approximately 9:30 p.m. [on August 9, 1996], at
    Broadway and Columbus Avenue, Livingston was
    preaching using amplification and had no permit for
    such amplification. Officer Milan Kangrga, on patrol
    in the North Beach area, responded to a noise com-
    plaint and requested that Livingston turn down his
    sound, which he did. Officer Kangrga returned,
    again in response to a noise complaint, at which time
    the volume was loud, and the complainant, Harry
    Wamack, who, by his address as indicated in the
    police report, resides near that intersection, signed a
    citizen’s arrest card. There is no indication of any
    encounter between the complainant and Livingston
    in this instance, however, or of the particular manner
    in which the complainant’s peace was disturbed.
    Nevertheless, given Livingston’s lack of permit, his
    knowledge of a complaint, and his increasing the
    volume of his amplifier to a high level once the
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO          4721
    police had left the scene, it cannot be said that Offi-
    cer Kangrga had no reasonable cause to believe Liv-
    ingston did so not to communicate but rather to
    annoy the individual who had seen fit to report him.
    [18] “The test for probable cause is whether facts and cir-
    cumstances within the officers’ knowledge are sufficient to
    warrant a prudent person, or one of reasonable caution, to
    believe, in the circumstances shown, that the suspect has com-
    mitted, is committing or is about to commit an offense.”
    Menotti v. City of Seattle, 
    409 F.3d 1113
    , 1149 (9th Cir. 2005)
    (internal quotation marks omitted). Although it is not disposi-
    tive, the City introduced testimony that under an informal pol-
    icy, its police officers have probable cause to believe a
    speaker “maliciously and willfully” caused a “loud and unrea-
    sonable” noise for purposes of § 415 where (1) a citizen has
    been unreasonably disturbed by sound volume, and is willing
    to sign a citizen’s arrest form to that effect; and (2) the police
    have cause to believe that the person who is the source of the
    sound knows that he or she is too loud, but refuses to turn
    down the volume. Under the test we enunciated in Menotti, to
    sustain the implied claim that the City officers subjected
    appellants to viewpoint discrimination due to the alleged cita-
    tion without probable cause, the question is whether a prudent
    person in the position of the officers who cited appellants
    would have believed that appellants were committing the
    offense of disturbing the peace under § 415, with the requisite
    specific intent to annoy. We conclude that city police here had
    probable cause.
    As for the August 2, 1996 citation, the district court reason-
    ably inferred that Rosenbaum had not adequately lowered the
    volume of his loudspeakers despite Officer Landon’s admon-
    ishment, because the volume remained sufficiently loud to
    rouse a neighborhood resident to complain and sign a citizen
    arrest form. Testimony to bolster appellants’ contention here
    that Rosenbaum turned off one of his loudspeakers, and
    turned down the second loudspeaker, was not so credible as
    4722   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    to overcome the inference that his purpose was to annoy Nar-
    vik, who, according to the investigating officer, had also
    requested that Rosenbaum reduce the volume. See Anderson
    v. City of Bessemer, 
    470 U.S. 564
    , 573 (1985) (recognizing
    that trial court’s credibility findings are subject to clear error
    and deserve special deference). Rosenbaum’s amplified
    speech was loud enough to draw Officer Landon to the scene
    twice within fifteen minutes. There was no clear error in the
    district court’s determination that Rosenbaum’s amplified
    sound remained at an unreasonable volume despite police
    warnings, from which we may conclude that Officer Landon
    had probable cause to issue a citation under § 415.
    The circumstances surrounding the August 9, 1996 citation
    also support probable cause for a violation of § 415. Here,
    Officer Kangrga similarly was twice called to the location
    where Livingston was engaged in unpermitted amplified
    speech. Appellants’ assertion that no evidence was submitted
    that Livingston actually “increased” the volume is immaterial
    in light of Officer Kangrga’s testimony. According to Officer
    Kangrga, Livingston disregarded the initial warning and
    maintained his volume at an unreasonably loud level so as to
    prompt another complaint. Because Livingston was on notice
    after the first warning that his volume was excessive, the dis-
    trict court could draw the permissive inference that Living-
    ston’s intent was to annoy or vex. No more is required to
    make a valid showing of probable cause.
    Because both incidents of citation under § 415 were legiti-
    mately based on probable cause, the district court correctly
    rejected appellants’ implied viewpoint discrimination claim.
    Moreover, the district court was also correct that even if prob-
    able cause were lacking, these two isolated incidents do not
    amount to a pattern or policy of abusive citation under § 415,
    given that two unrelated individuals prompted the complaints
    and two different officers responded. There was no evidence
    that the citations were coordinated by an overarching and
    improper policy or directive. See 
    Ulrich, 308 F.3d at 984
    .
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO                  4723
    [19] Because the district court’s findings of probable cause
    for enforcement of the noise ordinance against appellants is
    supported by evidence in the record, we affirm the district
    court’s rejection of the viewpoint discrimination claims.15
    VI
    Appellants argue that the City engaged in unconstitutional
    prior restraint in rejecting several permit applications based
    on appellants’ non-compliance with conditions attached to
    sound permits issued in the past.16
    [20] Laws that impose a prior restraint on the free exercise
    of speech have been disfavored as tantamount to censorship.
    See Near v. Minnesota, 
    283 U.S. 697
    , 713 (1931). In Fer-
    nandes v. Limmer the Fifth Circuit espoused the broad princi-
    ple that a “[d]enial of a permit for prior violations
    unquestionably entails a total abridgement of a citizen’s right
    to use the forum . . . .” 
    663 F.2d 619
    , 632 (5th Cir. Unit A
    Dec. 1981). In that case, the Fifth Circuit confronted a local
    ordinance governing literature distribution and fund solicita-
    tion at the Dallas-Fort Worth Airport, which provided, inter
    15
    We conclude that declaratory relief is unnecessary because it would
    “neither serve a useful purpose in clarifying and settling the legal relations
    in issue nor terminate the proceedings and afford relief from the uncer-
    tainty and controversy faced by the parties.” See United States v. Washing-
    ton, 
    759 F.2d 1353
    , 1357 (9th Cir. 1985).
    16
    Appellants assert this claim generally without any reference to partic-
    ular permit denials or dates when the denials might have occurred. While
    appellants cite a variety of exhibits in the briefing, these exhibits are not
    tied to specific motions the district court reviewed. Nor do appellants
    include in their Excerpts of Record copies of any particular Notices of
    Decision documenting the City’s permit denials. The City, for its part,
    included in the Supplemental Excerpts of Record copies of Notices of
    Decision for March 23, 1996; November 8, 1996; March 17, 1997; April
    1, 1997; April 7, 1997; June 25, 1997; and September 23, 1997. Because
    the district court correctly limited actionable conduct to that alleged in the
    complaint, and our appellate review is similarly limited, we consider only
    evidence of the May 23, 1996 denial.
    4724    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    alia, that permits could be withheld in the event “ ‘the Appli-
    cant or any agent or representative of the Applicant . . . has
    previously violated . . . Regulations of the Dallas-Fort Worth
    Regional Airport Board, or has violated any of the terms and
    provisions of any prior Permit.’ ” 
    Id. (quoting local
    ordi-
    nance) (alteration in original). Because this statutory subsec-
    tion effected a categorical denial of permits for prospective
    activity based solely on the fact of prior violations, the Fifth
    Circuit invalidated the ordinance on grounds of prior restraint.
    Id.; see also Kunz v. New York, 
    340 U.S. 290
    , 293 (1951)
    (holding denial of permit to engage in outdoor religious activ-
    ity based on earlier revocation of speech permit, where
    administrative officer had unbounded discretion, was imper-
    missible prior restraint).
    The City relies on a Notice of Decision, issued on May 23,
    1996, that upheld the denial of appellants’ application for an
    amplified sound permit proposed for five days in March of
    1996 at the intersection of Fifth and Market Streets.17 A hear-
    ing was held on May 8, 1996, at which Sergeant Terence Col-
    lins (head of the Permit Section) reviewed letters written by
    proponents and opponents of appellants’ use of amplified
    speech, in addition to hearing live public comment.
    Among other evidence, the hearing officer considered the
    testimony of Officer Dan Gallagher. Officer Gallagher ini-
    tially denied the March 1996 applications, and, in the preced-
    ing months, had fielded complaints from frustrated citizens
    who disparaged appellants’ use of excessively loud speech
    and music, and a purported lack of cooperation from represen-
    tatives of the SOS Ministries who, when asked, refused to
    17
    From the appellants’ briefing, it is evident that appellants decry as
    prior restraint some aspects of the decision-making process evinced in the
    March 23, 1996 Notice of Decision. Also, appellants in their complaint
    alleged the March 1996 permit denials as actionable conduct. To this
    extent, then, the May 23, 1996 Notice of Decision is an emblematic
    instance of the challenged City conduct.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO          4725
    lower their loudspeaker volume. Officer Gallagher also testi-
    fied that business owners in the vicinity complained that they
    could clearly hear appellants’ sound inside their establish-
    ments. Officer Gallagher further testified that he had frequent
    occasions to warn appellants about their excessive sound that
    violated § 47.2(7) (prohibiting sound that is audible beyond
    250 feet of its source), and that he ultimately sent appellants
    a letter informing them that they would not receive permits if
    they failed to comply with permit conditions that the volume
    be maintained at a reasonable level. Finally, Officer Gallagher
    recounted that at an outreach gathering in the area on March
    2, 1996, the City’s Noise Abatement Unit received complaints
    that required a police response. On March 9, 1996, the date
    on which the last previous permit was issued, Officer Gal-
    lagher noted that police were on hand to monitor appellants’
    use of sound and reported that the speech and music could be
    heard up to 400 feet away, which again spurred complaints to
    the Noise Abatement Unit.
    The hearing officer reviewed letters and heard comment by
    various neighborhood civic and business associations who
    similarly expressed frustration with appellants’ persistently
    loud amplified speech and music. These association represen-
    tatives mentioned that their members’ businesses were dis-
    rupted and residents were subject to loud volumes in the late
    evening when children were trying to sleep. In the case of an
    assistant manager of the City’s Visitor’s Information Center,
    the hearing officer heard that many visitors, some of whom
    could not speak English well, were unable to communicate
    effectively because of appellants’ use of amplified sound. In
    addition to recounting a few alleged incidents of being base-
    lessly “shut down,” Rosenbaum testified that the problem was
    not the level of sound, but rather “members of the homosex-
    ual community who oppose him.”18
    18
    Appellants’ on-going presence in some City neighborhoods caused a
    controversy because some gay members of the community and others
    4726    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    [21] Appellants are correct that in the May 23, 1996 Notice
    of Decision, the City cited prior instances in 1995 and early
    1996 where plaintiffs were unwilling to comply with permit
    conditions as part of its grounds for denial. However, this can-
    not be viewed in isolation. Aside from the past violations,
    what is plain from the varied public comments documented in
    the Notice of Hearing was that appellants’ persistent use of
    unreasonably loud amplified speech and music was disruptive
    to both businesses and residents at the specified location, the
    intersection of Fifth and Market Streets. The hearing officer
    considered not only the misconduct inherent in the past viola-
    tions, but also previous instances where plaintiffs received
    permits in March 1996 despite the widespread complaints in
    order to provide an “opportunity to reduce the volume of
    amplified sound in an effort to co-exist with the businesses in
    the area.”19 Despite this acknowledged accommodation, more
    complaints from the business community ensued describing
    the appellants’ unwillingness to lower the volume and the
    appellants’ occasional abusive response when asked to do so
    by fellow citizens. The hearing officer’s consideration of the
    past misconduct was thus aimed at determining the compati-
    bility of the amplified speech and music with the various
    were angered by what they perceived to be an “anti-gay” message in some
    of appellants’ Christian outreach. However, there is no evidence in the
    Notice of Decision that local residents or business owners offering public
    comment focused their opposition on appellants’ allegedly “anti-gay”
    message or that Sergeant Collins gave any weight to any animosity
    between the SOS Ministries and certain gay community members.
    19
    In a Notice of Decision, dated November 8, 1996, plaintiffs were
    denied a permit based on similar considerations about persistent noise
    complaints and unwillingness to comply with admonitions to lower the
    volume, i.e. appellants’ “spirit of non-cooperation.” In this instance, the
    hearing officer denied the permit because “amplified sound in the densely
    populated neighborhood of Sixth and Market Streets would have a nega-
    tive impact and be in conflict with the production at the Golden Gate The-
    ater.” Even this denial contained an invitation to reach an accommodation
    whereby plaintiffs could use a 9-watt bullhorn.
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO          4727
    interests in the proposed permit area, not the mere fact of any
    past violation.
    In this light, appellants’ reliance on the Fifth Circuit’s deci-
    sion in Limmer is inapt. The categorical permit ineligibility at
    issue in Limmer is different from the guided discretion exer-
    cised under § 47.2 to deny some of appellants’ applications.
    See Cox v. New Hampshire, 
    312 U.S. 569
    , 576 (1941). In
    Cox, the Supreme Court rejected a prior restraint claim by
    Jehovah’s Witnesses who chose to march without a parade
    permit because the city could legitimately enforce a permit
    requirement as a generally applicable condition for public
    gatherings where it did not otherwise control or suppress the
    distribution of literature, the display of placards or individual
    
    oration. 312 U.S. at 576
    (“If a municipality has authority to
    control the use of its public streets for parades or processions,
    as it undoubtedly has, it cannot be denied authority to give
    consideration, without unfair discrimination, to time, place
    and manner in relation to the other proper uses of the
    streets.”).
    In the successful facial challenge in Limmer, the impermis-
    sible prior restraint was effectuated because under no circum-
    stances could an applicant purge the taint of a previous
    violation. In sharp contrast, the evidence here supports the
    finding that the City police and its citizens engaged in an on-
    going negotiation with appellants to reach accommodation
    despite the widely complained-of noise violations under
    § 47.2. Unlike in Limmer, where the Fifth Circuit rejected the
    unequivocal “once a sinner, always a sinner” effect of the
    Dallas-Fort Worth ordinance, 
    see 663 F.2d at 632
    (internal
    quotation marks and citation omitted), appellants here were
    afforded opportunities to redeem past misconduct and bring
    their use of amplified sound into reasonable cooperation with
    other neighborhood activities at the proposed permit site.
    The Supreme Court decision in Kunz, 
    340 U.S. 290
    , on
    which appellants also rely, is inapposite. In Kunz, the defen-
    4728   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    dant city revoked a Baptist minister’s permit to hold an out-
    door public meeting because he had in the past violated a
    New York statute forbidding the ridicule and denunciation of
    other religions. 
    Id. at 292.
    The Supreme Court held that the
    permit denial due to a past violation of this statute was uncon-
    stitutional prior restraint because “the ordinance does not
    specify this as a ground for permit revocation.” Id.; see also
    
    id. at 294
    (“[W]e have consistently condemned licensing sys-
    tems which vest in an administrative official discretion to
    grant or withhold a permit upon broad criteria unrelated to
    proper regulation of public places.”).
    [22] Here, the hearing officer’s reference to appellants’ past
    violations in context do not show an absolute prohibition
    based on past violation, but rather that the City hearing officer
    sought to balance, within constitutional bounds, the compet-
    ing interests at the proposed permit location. In doing so, the
    hearing officer reasonably surmised from the instances of past
    misconduct, on-going complaints, and appellants’ apparent
    recalcitrance that the proposed amplified sound activity was
    unsuitable for the location and incompatible with other neigh-
    borhood activities. Unlike in Kunz, the City here did not
    deprive appellants of permits based on an arbitrary application
    of an unrelated statute. In contrast to Limmer, moreover, no
    provision of the City’s permitting scheme called for a
    mechanical rejection of appellants’ permit application because
    of past violation of the noise ordinance. Rather, the City’s
    refusal to issue permits in these limited instances was guided
    by conditions enumerated under S.F.P.C. § 47.2 (e.g. the 250-
    foot distance requirement), which, unlike the unrelated statute
    in Kunz, is expressly cross-referenced in S.F.P.C. § 43, the
    provision that governs permit issuance. Finally, as we noted
    previously, the fact that appellants received permits at differ-
    ent city locations reinforces the hearing officer’s finding that
    it was the proposed location in the March 1996 permit appli-
    cations, and not the content of appellants’ message, that was
    unsuitable. As in Cox, the City was within its police power to
    deny permits that might seriously interfere with its streets, see
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        
    4729 312 U.S. at 575
    , and did not engage in unconstitutional prior
    restraint.
    VII
    Appellants contend that the district court erred in not apply-
    ing a substantive analysis of their free speech claims under
    article 1, section 2(a) of the California Constitution, which, in
    appellants’ view, provides more expansive rights than federal
    protections, including a burden on the state to prove that the
    speech activity was “incompatible” with the public forum. In
    failing to show incompatibility, appellants argue, the City did
    not prove that amplified speech by Livingston and Rosen-
    baum “blocked the sidewalks, caused congestion or otherwise
    interfered with the use of the public forum . . . .” See App. Br.
    at 24. While acknowledging the asserted broader freedoms
    under article 1, section 2(a) of the California Constitution, the
    district court found, without further substantive analysis, “no
    reason” to conclude that appellants demonstrated a violation
    of state constitutional rights.
    [23] Article 1, section 2(a) of the California Constitution
    guarantees that “[e]very person may freely speak, write and
    publish his or her sentiments on all subjects.” Cal. Const. art.
    I, § 2(a). “The California Supreme Court has recognized that
    the California Constitution is ‘more protective, definitive and
    inclusive of rights to expression and speech’ than the First
    Amendment to the United States Constitution.” Glendale
    Assocs., Ltd. v. NLRB, 
    347 F.3d 1145
    , 1154 (9th Cir. 2003)
    (quoting Robins v. Pruneyard Shopping Ctr., 
    23 Cal. 3d 899
    ,
    908, 910 (1979), aff’d, 
    447 U.S. 74
    (1980)). Despite this
    greater expansiveness of speech rights, article 1, section 2(a)
    tolerates content neutral speech restriction commensurate with
    the First Amendment. See, e.g., Pruneyard Shopping 
    Ctr., 23 Cal. 3d at 909
    (recognizing such permissible restrictions
    under California Constitution). In the context of amplified
    sound regulation, time-place-manner restrictions also apply
    under California law. See Wollam v. City of Palm Springs, 59
    4730   ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO
    Cal. 2d 276, 278 (1963) (holding that blanket prohibition
    against the use of a stationary sound truck exceeded its justifi-
    cation under time, place and manner restriction because the
    outright ban was not limited to the elimination of loud or rau-
    cous noise or necessary for the prevention of traffic hazards).
    Here, appellants’ contention that their repeated use of
    amplified sound at excessive volume did not interfere with the
    public forum is unavailing. As discussed above, the City’s
    Permit Section was presented with ample evidence from busi-
    nesses and residents in the area around Fifth and Market
    Streets and elsewhere that the excessive volume was destruc-
    tive to commerce, interfered with residents’ ability to sleep,
    was often audible from more than 250 feet of the performance
    site in violation of § section 47.2(7) and prompted widespread
    complaints.
    [24] In contrast to Pruneyard Shopping, regulation under
    S.F.P.C. § 47.2 did not prohibit all speech activities, as appel-
    lants were informed that they could continue to preach if they
    would lower the volume of their loudspeakers. More impor-
    tantly, unlike the blanket prohibition invalidated in Wollam,
    §§ 47 and 47.2 incorporate reasonable enforcement limita-
    tions such as maintaining reasonable volume levels, distance
    requirements, specifying wattage and imposing bans only on
    amplification before 9:00 a.m. and after 10:00 p.m. See
    S.F.P.C. §§ 47(a) and 47.2. The consequences of amplifica-
    tion at excessive volume is a genuine form of “interference”
    with the public forum even if it did not block traffic or cause
    congestion. As such, enforcement of the time, place and man-
    ner restriction under S.F.P.C. §§ 43 and 47.2 to curb appel-
    lants’ use of amplified sound at excessive volumes did not run
    afoul of the California Constitution.
    VIII
    In conclusion, San Francisco’s enforcement of its noise
    abatement ordinance, in its permitting and its law enforce-
    ROSENBAUM v. CITY AND COUNTY OF SAN FRANCISCO        4731
    ment activities, did not violate the federal constitutional guar-
    antee of equal protection of the laws, or its protection of First
    Amendment rights. Similarly, San Francisco’s enforcement of
    its noise restrictions against appellants did not offend the Cal-
    ifornia Constitution.
    AFFIRMED.
