    Appeal from the United States District Court

    No. 09 CV 754—John W. Darrah, Judge.
    A RGUED JUNE 1, 2012—D ECIDED S EPTEMBER 10, 2012
    Before F LAUM, R OVNER, and W ILLIAMS, Circuit Judges.
    F LAUM, Circuit Judge. A Chicago ordinance criminalizes
    an individual’s refusal to leave a scene when so
    instructed by a police officer when three or more indi-
    viduals are engaging in disorderly conduct nearby.
    Buddy Bell was arrested under that ordinance, the en-
    forcement of which he presently seeks to enjoin as
    2                                             No. 11-2408
    facially violative of the First and Fourteenth Amendments.
    The district court dismissed his claims, ruling that
    he lacked standing to sue for injunctive relief.
    We hold that Buddy Bell may sue to enjoin the
    ordinance as facially unconstitutional. We also conclude
    that Chicago Municipal Code § 8-4-010(d) (hereinafter
    “Subsection D”) substantially inhibits protected speech
    and is not amenable to clear and uniform enforcement.
    We partially invalidate the ordinance and reverse.
    I. Background
    On January 7, 2008, Buddy Bell participated in a
    protest against Operation Iraqi Freedom on the corner of
    Dearborn Street and Jackson Boulevard in downtown
    Chicago. He, along with other protesters, held a banner
    that said, “End the war and occupation TROOPS HOME
    NOW.” At the time, President Bush was at a luncheon
    at the nearby Union League Club.
    One protester, Andy Thayer, entered the street carrying
    a large banner and, according to Chicago police,
    advanced on the Deputy Chief who was monitoring the
    area on a Segway. Thayer was arrested, handcuffed, and
    placed in a squadrol. Bell and two other protesters, their
    own banner in hand, began approaching the squadrol,
    also walking into the street. The police ordered the
    three men to get back on the sidewalk several times.
    They refused and began chanting, “Hell no, we won’t
    go. Set him free.” Chicago police again ordered Bell
    and the other protesters to get back on the sidewalk.
    They refused, and the police arrested them for disorderly
    No. 11-2408                                                   3
    conduct. In particular, police arrested Bell pursuant
    to Subsection D, which criminalizes an individual’s
    behavior when he “knowingly . . . [f]ails to obey a lawful
    order of dispersal by a person known by him to be a
    peace officer under circumstances where three or more
    persons are committing acts of disorderly conduct in
    the immediate vicinity, which acts are likely to cause
    substantial harm or serious inconvenience, annoyance
    or alarm.” Chicago Municipal Code § 8-4-010(d).
    A state court acquitted Bell of violating Subsection D.
    Subsequently, Bell sued various members of Chicago
    law enforcement and the City of Chicago in federal
    court for violating his First, Fourth, and Fourteenth
    Amendment rights, as well as for malicious prosecu-
    tion and indemnification. See 
    42 U.S.C. § 1983
    . He ulti-
    mately dropped all but his indemnification claim
    against the City of Chicago. He presented his Fourth
    Amendment claims of false arrest and his malicious
    prosecution claim to a jury, which found in favor of
    the defendants. The jury returned three special verdicts.
    It found (1) that Chicago police had probable cause to
    arrest Bell for disorderly conduct under an ordinance of
    the City of Chicago; (2) that Chicago police lacked
    probable cause to arrest Bell for disorderly conduct
    under Illinois law; and (3) that Chicago police lacked
    probable cause to arrest Bell for obstructing a peace
    officer under Illinois law.1
    1
    In relevant part, the district court instructed the jury that
    “[t]here is probable cause for an arrest if at the moment the

    Bell’s claims that Subsection D facially contravened
    the First and Fourteenth Amendments remained before
    the district court. He alleged unconstitutional over-
    breadth and vagueness, respectively. Bell moved for
    declaratory relief and a permanent injunction barring
    enforcement of Subsection D, which the district court
    denied. The district court then dismissed Bell’s First
    and Fourteenth Amendment challenges to Subsection D,
    ruling that Bell lacked standing to apply for injunctive
    relief because he did not demonstrate a likelihood of
    future or repeat injury. Bell presently and timely
    appeals the judgment of the district court.

    (...continued)
    arrest was made a prudent person would have believed that
    the plaintiff, Buddy Bell, had committed or was committing[] a
    crime. . . . [U]nder an ordinance of the City of Chicago a person
    commits disorderly conduct when he knowingly fails to obey
    a lawful order of dispersal by a person known to him to be a
    peace officer under circumstances where three or more
    persons are committing acts of disorderly conduct in the
    immediate vicinity, which acts are likely to cause substantial
    harm or serious inconvenience, annoyance or alarm. Under
    Illinois law a person commits disorderly conduct when he
    knowingly does any act in such an unreasonable manner as
    to alarm or disturb another and provoke a breach of the
    peace. Under Illinois law a person who knowingly obstructs
    the performance of one known to be a peace officer of any
    authorized act within his official capacity commits a Class A
    misdemeanor.”

    II. Discussion
    We review a party’s standing to pursue injunctive
    relief de novo, see ACLU of Ill. v. Alvarez, No. 11-1286, 
    2012 WL 1592618
    , at *5 (7th Cir. May 8, 2012), as we do chal-
    lenges to a statute’s constitutionality, see United States
    v. Juarez, 
    454 F.3d 717
    , 719 (7th Cir. 2006).
    A. The District Court’s Findings on Bell’s Standing
    An Article III court enjoys jurisdiction over a case
    only if the plaintiff demonstrates that he suffered an
    injury in fact, the defendant’s actions caused the injury,
    and the remedy he seeks would redress his injury. See
    Allen v. Wright, 
    468 U.S. 737
    , 751 (1984); see also Alvarez,
    
    2012 WL 1592618
    , at *5. When the plaintiff applies for
    prospective relief against a harm not yet suffered—or one
    he believes he will suffer again—he must establish that
    he “is immediately in danger of sustaining some direct
    injury as the result of the challenged official conduct[,]
    and [that] the injury or threat of injury [is] both real and
    immediate, not conjectural or hypothetical.” City of Los
    Angeles v. Lyons, 
    461 U.S. 95
    , 102 (1983) (internal quotation
    marks omitted). Otherwise, he fails to allege an actual
    case or controversy before the court. See U.S. C ONST.
    art. III, § 2, cl. 1.
    As a general matter, a plaintiff who wishes to engage
    in conduct arguably protected by the Constitution, but
    proscribed by a statute, successfully demonstrates an
    immediate risk of injury. See Alvarez, 
    2012 WL 1592618
    ,
    at *5. The existence of the statute constitutes the gov-
    6                                               No. 11-2408
    ernment’s commitment to prosecute in accordance with
    it and, thus, a concrete prospect of future harm for one
    who would flout it. 
    Id.
     (citing Bauer v. Shepard, 
    620 F.3d 704
    , 708 (7th Cir. 2010); Majors v. Abell, 
    317 F.3d 719
    , 721
    (7th Cir. 2003)). Accordingly, when a plaintiff expresses
    a credible intention to disobey a statute, a sufficient
    likelihood of injury exists, and a pre-enforcement chal-
    lenge is appropriate. See Alvarez, 
    2012 WL 1592618
    , at *5
    (citing Brandt v. Vill. of Winnetka, Ill., 
    612 F.3d 647
    , 649
    (7th Cir. 2010); Babbitt v. United Farm Workers Nat’l
    Union, 
    442 U.S. 289
    , 298 (1979)). He need not wait to be
    arrested to bring suit for injunctive relief.
    We distinguish claims where a statute criminalizes
    the plaintiff’s conduct or desired conduct from those
    where the plaintiff seeks relief from the defendant’s
    criminal or unconstitutional behavior. For the latter type
    of claim, the putative injury typically proves too
    remote or attenuated to sustain our jurisdiction under
    Article III. See Lyons, 
    461 U.S. at 105-06
     (finding no
    standing to sue for injunctive relief where the plaintiff
    suffered an unconstitutional chokehold during a traffic
    stop, feared that he would endure a chokehold again,
    but did not allege that every police officer in Los Angeles
    always applied chokeholds or that the City itself ordered
    chokeholds as protocol); O’Shea v. Littleton, 
    414 U.S. 488
    , 494-99 (1974) (finding no standing to sue for
    injunctive relief where plaintiffs alleged discriminatory
    law enforcement and inferred future harm based
    on a pattern of past violative conduct, not the likely en-
    forcement of a statute). The same logic obtains when
    a statute was or would have to be misapplied to justify
    No. 11-2408                                                7
    the plaintiff’s arrest. In Schirmer v. Nagode, for example,
    protesters who opposed military recruitment organized
    to hand out flyers near a recruiting booth at the Taste
    of Chicago. 
    621 F.3d 581
    , 583 (7th Cir. 2010). When
    the protesters ignored the police’s request to move to a
    designated protest zone and a later request to disperse,
    they were arrested pursuant to Subsection D. 
    Id.
     The
    charges were ultimately dismissed, and the plaintiffs
    sued under Section 1983. We held that the plaintiffs
    lacked standing to facially challenge Subsection D or
    pursue injunctive relief because the law “c[ould not]
    fairly be read to prohibit peaceful protests of the sort [in
    which they were engaged]” and concluded that the
    police’s “clear misuse of a law d[id] not provide a basis
    for a federal court to explore that law’s facial constitu-
    tionality.” 
    Id. at 587-88
    . That is, we concluded that, what-
    ever injury the plaintiffs suffered by virtue of their
    arrests pursuant to Subsection D and whatever damages
    to which they were entitled, 
    id. at 583
    , a facial
    challenge and injunctive relief were inappropriate
    because the statute itself did not portend arrest and
    prosecution for peaceful protests. 
    Id. at 588
     (“These plain-
    tiffs’ experience appears, on this record, to be the result
    of an isolated misuse of the failure-to-disperse provi-
    sion and indicates that they are not reasonably likely
    to face a future prosecution if section 8-4-010(d) is
    enforced according to its terms.”).
    In this case, the district court, applying Schirmer, denied
    Bell standing, finding that the circumstances of his
    arrest were indistinguishable from those in Schirmer
    and that he “ha[d] not demonstrated more than a wholly
    8                                                No. 11-2408
    speculative possibility of criminal consequences.” We
    conclude, contrary to the district court’s assessment,
    that the circumstances prompting Bell’s arrest differ
    from those in Schirmer. The protesters in this case were
    not calmly holding a sign or distributing leaflets. They
    were shouting at police and advancing on a police vehi-
    cle. Regardless of the degree to which Bell participated in
    those activities, at least three other people did so, and he
    did not move as directed by a police officer. The facts of his
    case situate him squarely within Subsection D’s scope,
    giving police probable cause to arrest him. Thus, unlike in
    Schirmer, law enforcement did not misapply the statute to
    arrest and prosecute him; Schirmer’s misapplication
    analysis cannot operate to reduce Bell’s alleged fear of
    arrest to speculation or to deny him standing to seek
    injunctive relief or facially challenge the law.
    B. Bell Successfully Establishes Injury and Has
    Standing to Facially Challenge Subsection D
    as Overly Broad and Vague
    Bell argues that Subsection D is constitutionally infirm
    because it is vague and overbroad, both of which, if true,
    are facial failings. The defendants insist, however, that
    despite the fact that Subsection D was not misapplied
    against Bell, he lacks standing to sue for injunctive
    relief and, by implication, to facially challenge the ordi-
    nance because he cannot demonstrate a concrete injury
    unless he intends to participate in a protest where three
    or more persons in his immediate vicinity are commit-
    ting acts of disorderly conduct—behaving in such an
    No. 11-2408                                                 9
    unreasonable manner as to provoke, make or aid in
    making a breach of the peace, see Chicago Municipal
    Code § 8-4-010(a) (defining “disorderly conduct”). They
    contend that his involvement in political protests,
    without more, is not proscribed by Subsection D, and
    his hope to participate in the future does not insure
    his arrest as necessary to confer standing for injunctive
    relief.
    1.   Overbreadth: Standing to Bring His First Amend-
    ment Claim
    Facial invalidation typically requires that “no set of
    circumstances exists under which the [law] would be
    valid,” United States v. Salerno, 
    481 U.S. 739
    , 745 (1987), so
    the remedy “must be injunctive and declaratory,” Ezell v.
    City of Chicago, 
    651 F.3d 684
    , 698 (7th Cir. 2011) (emphasis
    in original). Though it also demands injunctive and
    declaratory relief if successful, an overbreadth claim
    is unique from traditional facial challenges in that it
    does not require a plaintiff to plead or prove that the
    law is unconstitutional in every application. See Ezell,
    651 F.3d at 698 n.8 (“Overbreadth claims are a distinct
    type of facial challenge.” (quoting United States v.
    Stevens, 
    130 S. Ct. 1577
    , 1587 (2010))); Hodgkins ex rel.
    Hodgkins v. Peterson, 
    355 F.3d 1048
    , 1056 (7th Cir. 2004)
    (“[T]he First Amendment doctrine of overbreadth is
    an exception to our normal rule regarding the standards
    for facial challenges.” (quoting Virginia v. Hicks, 
    539 U.S. 113
    , 118 (2003))). Content-neutral regulations—laws
    that restrict expressive conduct for reasons unrelated to
    10                                                     No. 11-2408
    the expression itself, see Boos v. Barry, 
    485 U.S. 312
    , 320
    (1988)—suffer from overbreadth and necessitate facial
    invalidation if their unconstitutional applications
    against otherwise protected expression outnumber their
    legitimate ones. For such “technical overbreadth” claims,
    R.A.V. v. City of St. Paul, Minn., 
    505 U.S. 377
    , 381 n.3 (1992)
    (defining “technical overbreadth” as “a claim that the
    ordinance violated the rights of too many third parties”),
    the question is one of magnitude. Where a sufficient
    imbalance exists, the statute proves facially invalid, not
    because it lacks any conceivable constitutional application,
    but because the “threat of [its] enforcement . . . deters
    people from engaging in constitutionally protected
    speech, inhibiting the free exchange of ideas.” United
    States v. Williams, 
    553 U.S. 285
    , 292 (2008). Technically
    overbroad statutes, in short, must fail because they uncon-
    stitutionally chill protected expression.2
    2
    A law that suffers from “technical overbreadth” may be
    analytically distinguished from one that fails as substantively
    overbroad, meaning that it “restrict[s] more speech than the
    Constitution permits . . . because it is content based.” R.A.V.,
    
    505 U.S. at
    381 n.3. The latter subset of overbreadth plagues
    regulations that target a category of subject matter or a particu-
    lar viewpoint, see, e.g., 
    id. at 382
     (“The First Amendment
    generally prevents government from proscribing speech or even
    expressive conduct because of disapproval of the ideas ex-
    pressed.” (internal citations omitted)); see also Stevens, 
    130 S. Ct. at 1584
     (“[A]s a general matter, the First Amendment means
    that government has no power to restrict expression because
    of its message, its ideas, its subject matter, or its content.”

    No. 11-2408                                                     11
    Chilled speech is, unquestionably, an injury supporting
    standing, see Hoover v. Wagner, 
    47 F.3d 845
    , 847 (7th Cir.
    1995) (“Arrest, prosecution, and conviction are tangible
    harms, and so is abandoning one’s constitutional right
    of free speech in order to avert those harms.”); see also
    Sec’r of State of Md. v. Joseph H. Munson Co., 
    467 U.S. 947
    ,
    958 (1984) (“Facial challenges to overly broad statutes
    are allowed not primarily for the benefit of the litigant,
    but for the benefit of society—to prevent the statute
    from chilling the First Amendment rights of other
    parties not before the court.”), but a plaintiff’s notional or
    subjective fear of chilling is insufficient to sustain a
    2
    (...continued)
    (quoting Ashcroft v. ACLU, 
    535 U.S. 564
    , 573 (2002))), where
    the government cannot demonstrate a compelling state inter-
    est in regulating that idea or achieve it through narrowly
    tailored means, see Police Dep’t of Chicago v. Mosely, 
    408 U.S. 92
    , 94-95, 101-02 (1972) (explaining that laws that discriminate
    on the basis of message must prove “an appropriate govern-
    mental interest suitably furthered by the differential treatment”);
    see also Boos, 
    485 U.S. at 321
     (noting that content-based restric-
    tions are “subjected to the most exacting scrutiny” and, thus,
    must be narrowly tailored to meet a compelling state interest).
    When a content-based regulation fails strict scrutiny—and is,
    therefore, substantively overbroad—there exists no possible
    application of that law consistent with the First Amendment’s
    guarantees. See K ATHLEEN M. S ULLIVAN & G ERALD G UNTHER ,
    C ONSTITUTIONAL L AW 1093 (16th ed. 2007) (suggesting that
    overbreadth may be viewed as one application of strict scrutiny
    (citing Monaghan, Overbreadth, 1981 SUP . C T . R EV . 1, 1081
    (1982))).
    12                                                  No. 11-2408
    court’s jurisdiction under Article III, see Laird v. Tatum,
    
    408 U.S. 1
    , 11, 13-14 (1972) (holding that where a defen-
    dant’s chilling claims stemmed from government sur-
    veillance techniques and not a proscriptive regulation,
    “[a]llegations of a subjective ‘chill’ [were] not an
    adequate substitute for a claim of specific present
    objective harm or a threat of specific future harm”). The
    plaintiff must substantiate a concrete and particularized
    chilling effect on his protected speech or expressive
    conduct to pursue prospective relief.3 He does so where,
    for example, he challenges an “exercise of government
    power [that is] regulatory, proscriptive, or compulsory in
    nature, and [he] was either presently or prospectively
    subject to the regulations, proscriptions, or compulsions
    that he was challenging.” Laird, 408 U.S. at 11; see also
    Initiative and Referendum Inst. v. Walker, 
    450 F.3d 1082
    , 1089
    3
    This rule applies only where the plaintiff is alleging a
    chilling of his own protected speech as the injury in fact. Note,
    however, that where a plaintiff faced arrest under an allegedly
    overbroad ordinance, but was either not chilled or not
    engaging in protected expression, he could still facially chal-
    lenge the statute on behalf of others whose protected expression
    would be hampered by the law. See Munson, 
    467 U.S. at 958
    (noting that with respect to an overbreadth challenge, “a party
    [may] assert the rights of another without regard to the
    ability of the other to assert his own claims and with no re-
    quirement that the person making the attack demonstrate that
    his own conduct could not be regulated by a statute drawn
    with the requisite narrow specificity.” (quoting Broadrick v.
    Oklahoma, 
    413 U.S. 601
    , 612 (1973)) (internal quotation marks
    omitted)); Gooding v. Wilson, 
    405 U.S. 518
    , 520-21 (1972) (same).
    No. 11-2408                                             13
    (10th Cir. 2006) (“We hold that plaintiffs in a suit for
    prospective relief based on a ‘chilling effect’ on speech
    can satisfy the requirement that their claim of injury be
    ‘concrete and particularized’ by (1) evidence that in the
    past they have engaged in the type of speech affected
    by the challenged government action; (2) affidavits or
    testimony stating a present desire, though no specific
    plans, to engage in such speech; and (3) a plausible
    claim that they presently have no intention to do so
    because of a credible threat that the statute will be en-
    forced.”).
    Part and parcel of his overbreadth claim, Bell alleges
    both that his own speech has been chilled by Subsection D
    and that the ordinance might chill others from exer-
    cising their First Amendment rights. We conclude that
    he establishes a chilling injury sufficient to satisfy
    Article III standing. His past participation in a protest
    buttresses his representation that he wishes to participate
    in protests or assemblies in Chicago in the future, and
    his past arrest under Subsection D supports his claim
    that the enforcement of the ordinance has chilled his
    willingness to participate again. Cf. City of Houston, Tex.
    v. Hill, 
    482 U.S. 451
    , 459 n.7 (1987) (“[The defendant’s]
    record of arrests under the ordinance and his adopted
    role as citizen provocateur give him standing to chal-
    lenge the facial validity of the ordinance.”). Indeed, his
    past experience with the ordinance lends credibility to
    his assertion that the City will enforce Subsection D
    against individuals engaged in protected speech
    activities when certain triggering events occur.
    14                                              No. 11-2408
    Contrary to the City’s argument, the fact that the ordi-
    nance applies only if triggered does not attenuate
    Bell’s likelihood of prosecution under the statute or
    subvert the concreteness of his chilling injury. The puta-
    tive vagueness surrounding those triggering events, see
    infra Part II.B.2, compounds his chilling claim: when one
    cannot know what triggers the ordinance such that it
    will be enforced, he may fairly assume that it can and
    will always be enforced and that total abstention from
    the protected activity is necessary to avoid arrest and
    prosecution. Bell successfully alleges a chilling injury,
    and we hold that he enjoys standing to sue for injunctive
    relief and facially challenge Subsection D as overly broad.
    2.   Vagueness: Standing to Bring a Fourteenth Amend-
    ment Claim
    A vagueness claim alleges that, as written, the law either
    fails to provide definite notice to individuals regarding
    what behavior is criminalized or invites arbitrary and
    discriminatory enforcement—or both. See Skilling v. United
    States, 
    130 S. Ct. 2896
    , 2927-28 (2010) (“To satisfy due
    process, ‘a penal statute must define the criminal offense
    (1) with sufficient definiteness that ordinary people can
    understand what conduct is prohibited and (2) in a
    manner that does not encourage arbitrary and discrim-
    inatory enforcement.’ The void-for-vagueness doctrine
    embraces these requirements.” (quoting Kolender v.
    Lawson, 
    461 U.S. 352
    , 357 (1983))). Although it derives
    from the Fourteenth Amendment, a statute that is
    vague may implicate a plaintiff’s First Amendment
    No. 11-2408                                               15
    rights, fostering those same chilling concerns that attend
    an overbreadth challenge. See Hynes v. Mayor of Oradell,
    
    425 U.S. 610
    , 620 (1976) (“The general test of vagueness
    applies with particular force in review of laws dealing
    with speech. . . . [A] man may the less be required to act
    at his peril [where a statute has a potentially inhibiting
    effect on speech], because the free dissemination of
    ideas may be the loser.” (quoting Smith v. California, 
    361 U.S. 147
    , 151 (1959))). In those instances when an
    imprecise law implicates speech and assembly rights,
    an injured plaintiff may also facially challenge a statute
    as void for vagueness. See Penny Saver Publ’ns, Inc. v. Vill.
    of Hazel Crest, 
    905 F.2d 150
    , 154 n.2 (7th Cir. 1990) (“The
    first amendment ‘chill’ and its consequential injury . . .
    confer[] standing for an action based on a vagueness
    theory.” (citing Hynes, 
    425 U.S. at
    621 n.5)).
    Bell argues that Subsection D fails both tenets of vague-
    ness and, like the ordinance’s overbreadth, precipitates
    a chilling injury. As used in the ordinance, he con-
    tends, the terms “serious inconvenience,” “annoyance,”
    and “alarm” vest unbridled authority in law enforcement
    such that one cannot know what conduct triggers Sub-
    section D or whether the law is evenly enforced. As a
    result, he maintains, it is impossible for him to know
    whether a future assembly he wishes to attend will
    evince transgressing behavior from his fellow protesters,
    and, especially since he cannot control their behavior,
    he must abstain from all protests unless he wishes to
    risk prosecution under Subsection D. We conclude that
    Bell may, therefore, facially challenge Subsection D as
    unconstitutionally vague and sue for injunctive relief.

    C. First Amendment Challenge: Overbreadth
    Facial invalidation for technical overbreadth is “strong
    medicine,” see New York v. Ferber, 
    458 U.S. 747
    , 769 (1982)
    (quoting Broadrick v. Oklahoma, 
    413 U.S. 601
    , 613 (1973)),
    and is inappropriately employed unless the statute
    “substantially” criminalizes or suppresses otherwise
    protected speech vis-à-vis its “plainly legitimate sweep.”
    See Williams, 
    553 U.S. at 292-93
     (“In order to maintain
    the appropriate balance, we have vigorously enforced
    the requirement that a statute’s overbreadth be sub-
    stantial, not only in an absolute sense, but also relative to
    the statute’s plainly legitimate sweep.” (emphasis in
    original)). We, therefore, begin by construing the
    ordinance to assess its overall reach and impact upon
    the First Amendment.4 
    Id.
     In doing so, we must adopt
    any limiting construction proffered by a state court.
    See Kolender, 
    461 U.S. at 355
    . If Subsection D is “readily
    susceptible” to an interpretation that would preserve
    its constitutionality, we must uphold it, but we “will not

    We have already upheld as constitutionally sound the
    definition of “disorderly conduct” provided in Chicago Munici-
    pal Code § 8-4-010(a). See United States v. Woodard, 
    376 F.2d 136
     (7th Cir. 1967); see also Broadrick, 
    413 U.S. at 613-14
     (defend-
    ing, as a general matter, the facial constitutionality of “disor-
    derly conduct” or “breach of the peace” statutes). Bell chal-
    lenges only the expounded definition in Subsection D, and
    we, thus, limit our review to the phrase in dispute: “which
    acts are likely to cause substantial harm or serious inconve-
    nience, annoyance or alarm.” See Chicago Municipal Code
    § 8-4-010(d).
    No. 11-2408                                                     17

    ments.” Virginia v. Am. Booksellers Ass’n, 
    484 U.S. 383
    ,

    The Illinois Supreme Court has made clear that disor-
    derly conduct statutes in the state, including Chicago’s
    disorderly conduct ordinance, do not criminalize speak-
    ing. See People v. Raby, 
    240 N.E.2d 595
    , 598 (Ill. 1968)
    (holding, with respect to Illinois’ disorderly conduct
    statute, that “under no circumstances would the
    statute allow persons to be punished merely for peace-
    fully expressing unpopular views”); see also In re B.C.,
    
    680 N.E.2d 1355
    , 1369 (Ill. 1997) (“Disorderly conduct
    statutes must be narrowly drawn or construed so that
    the statutes do not reach protected speech.”).5 More-
    over, the Illinois Supreme Court has recognized that
    in enforcing disorderly conduct statutes, “the police
    may not stop a peaceful demonstration merely because
    a hostile crowd which does not agree with the views of
    the demonstrators threatens violence and, in fact, owe
    a duty to protect the peaceful individuals from acts
    of hostility.” See City of Chicago v. Weiss, 
    281 N.E.2d 310
    ,
    315 (Ill. 1972). The Illinois Supreme Court consequently
    limits Subsection D to preclude a “heckler’s veto.” So
    5
    The Illinois Supreme Court rightly maintains that disorderly
    conduct statutes could reach speech expressed through incite-
    ment, see Brandenburg v. Ohio, 
    395 U.S. 444
     (1969) (per curiam),
    fighting words, see Chaplinsky v. New Hampshire, 
    315 U.S. 568
    (1942), or obscenity, see Miller v. California, 
    413 U.S. 15
     (1973),
    which are modes of expression that are not protected by the
    First Amendment. See B.C., 
    680 N.E.2d at 1369
    .
    18                                                  No. 11-2408
    long as a speaker and his supporters refrain from acts
    of disorderly conduct, police may not order them to
    disperse when they are confronted by a hostile crowd.
    In light of the Illinois Supreme Court’s constructions,
    disorderly conduct does not refer to peaceful speech
    or assembly. The ordinance’s triggering conduct
    cannot be an act constituting protected expression (e.g.,
    picketing or leafleting) or aimed at disrupting protected
    expression. Nevertheless, Subsection D may still im-
    plicate protected expression because, once triggered, it
    may be applied to disperse people engaged in peaceful
    speech or expressive conduct, including on topics of
    public concern. See, e.g., Engquist v. Or. Dep’t of Agric., 
    553 U.S. 591
    , 600 (2008) (identifying speech on matters of
    public concern as at the core of First Amendment pro-
    tection). The question, then, is whether the law sub-
    stantially does so. See Williams, 533 U.S. at 292-93.6
    6
    Expounding upon substantial overbreadth as a standard, the
    Supreme Court has stated, “The concept of substantial
    overbreadth is not readily reduced to an exact definition. It is
    clear, however, that the mere fact that one can conceive of
    some impermissible applications of a statute is not sufficient to
    render it susceptible to an overbreadth challenge. . . . In short,
    there must be a realistic danger that the statute itself will
    significantly compromise recognized First Amendment
    protections of parties not before the Court for it to be
    facially challenged on overbreadth grounds.” City Council v.
    Taxpayers for Vincent, 
    466 U.S. 789
    , 800-01 (1984). The Court’s
    discussion of this standard underscores that both the

    Per the plain language of the ordinance, law enforce-
    ment may order an individual to disperse when at least
    three others in his vicinity behave in a way that amounts
    to disorderly conduct “likely to cause substantial harm
    or serious inconvenience, annoyance or alarm.” Chicago
    Municipal Code § 8-4-010(d) (emphasis added). The
    ordinance phrases these worrisome effects disjunctively,
    so police may order dispersal if any one of them is
    likely to occur as a result of the conduct.
    1.   Dispersal on the Basis of Likely Substantial Harm
    It is well established that otherwise protected speech
    may be curtailed when an assembly stokes—or is threat-
    ened by—imminent physical or property damage. The
    Supreme Court has long held beyond First Amendment
    protection speech or association that incites its audience
    to imminent violence. See Brandenburg v. Ohio, 
    395 U.S. 444
    , 447 (1969) (per curiam). So, too, speech or associa-

    numerosity of unconstitutional applications and the
    importance of the speech affected may inform the substantial-
    ness of a law’s infirmity. See E RWIN C HEMERINSKY , C ONSTITU -
    TIONAL L AW P RINCIPLES AND P OLICIES 944-46 (3d ed. 2006) (citing
    Richard Fallon, Jr., Making Sense of Overbreadth, 100 Y ALE L.J.
    853, 894 (1991)). For the conclusion that a finding of sub-
    stantial overbreadth depends upon a court’s implicit
    judgments about whether expression is protected and whether
    protected expression has been constitutionally regulated, see
    S ULLIVAN & G UNTHER , supra note 3, at 1082.

    tion that poses to a particular listener or group of
    listeners an unambiguous invitation to brawl. See
    Chaplinsky v. New Hampshire, 
    315 U.S. 568
    , 572 (1942); cf.
    Cohen v. California, 
    403 U.S. 15
    , 22-24 (1971). And when,
    for whatever reason, immediate danger to speakers and
    protesters exists, the Court has held that speech may
    be curtailed to prevent a riot or serious bodily injury
    to those gathered. See Feiner v. New York, 
    340 U.S. 315
    ,
    321 (1951) (upholding law enforcement’s right to
    interfere with protected expression when “faced with a
    crisis”); see also Terminiello v. City of Chicago, 
    337 U.S. 1
    , 4-5
    (1949) (holding that protected speech may not be
    abridged or censored short of “a clear and present
    danger of a serious substantive evil that rises far above
    public inconvenience, annoyance, or unrest”). When
    such conditions emerge, they bespeak dispersal as a
    necessary means of averting danger and damage, and
    the City may empower law enforcement to order people
    to disperse without unconstitutionally burdening free
    speech. In turn, law enforcement may arrest those indi-
    viduals that refuse to leave when ordered, as their
    failure to comply exacerbates the danger afflicting the
    City and hinders law enforcement’s ability to secure the
    situation. See United States v. O’Brien, 
    391 U.S. 367
    , 376
    (1968) (“[W]hen ‘speech’ and ‘nonspeech’ elements are
    combined in the same course of conduct, a sufficiently
    important governmental interest in regulating the
    nonspeech element can justify incidental limitations on
    First Amendment freedoms. . . . [A] government regulation
    is sufficiently justified if it is within the constitutional
    power of the Government; if it furthers an important or
    No. 11-2408                                            21
    substantial governmental interest; if the govern-
    mental interest is unrelated to the suppression of free
    expression; and if the incidental restriction on alleged
    First Amendment freedoms is no greater than is essential
    to the furtherance of that interest.”).
    If, as the Illinois Supreme Court assures, Subsection D
    cannot be triggered by peaceful or otherwise protected
    expression, then the logical corollary is that the
    substantial harm contemplated by Subsection D is
    physical danger or damage to the people and property
    nearby. See M ERRIAM-W EBSTER D ICTIONARY O NLINE,
    available at http://merriam-webster.com/dictionary (last
    visited August 2, 2012) (defining “substantial” as “real,”
    “essential,” or “considerable in quantity” and “harm”
    as “physical or mental damage”); see also Shlahtichman v.
    1-800 Contacts, Inc., 
    615 F.3d 794
    , 799 (7th Cir. 2010)
    (“Dictionaries are a helpful resource in ascertaining the
    common meaning of terms that a statute leaves unde-
    fined.”). Accordingly, to the extent that Subsection D
    authorizes dispersal when an assembly creates or is
    threatened by “substantial harm,” it does not improperly
    infringe upon protected speech. We cannot say the
    same, however, for authorizing dispersal on the basis
    of “serious inconvenience, annoyance or alarm.” Chicago
    Municipal Code § 8-4-010(d).
    2.   Dispersal on the Basis of Likely Serious Inconve-
    nience
    The term “serious inconvenience,” in the context of a
    disorderly conduct statute, likely envisions nuisances
    22                                            No. 11-2408
    such as the obstruction of public passages or amplified
    noise that are well within a city’s power to regulate.
    See M ERRIAM-W EBSTER D ICTIONARY O NLINE, available at
    http://merriam-webster.com/dictionary (last visited
    August 2, 2012) (defining “serious” as “having
    important or dangerous possible consequences” and
    “inconvenience” as “not convenient, especially in giving
    trouble or annoyance”); see also Coates v. City of Cincin-
    nati, 
    402 U.S. 611
    , 614 (1986) (underscoring that a city
    is “free to prevent people from blocking sidewalks, ob-
    structing traffic, littering streets, committing assaults,
    or engaging in countless other forms of antisocial con-
    duct”). Chicago has identified and proscribed those
    serious inconveniences it finds problematic in its
    Municipal Code, authorizing law enforcement to
    penalize individual perpetrators when they commit a
    specific nuisance that compromises the City’s safety and
    order. See, e.g., Chicago Municipal Code § 10-8-330(b)
    (prohibiting all parades on public ways without a per-
    mit); § 8-32-070 (regulating music and amplified sound);
    § 8-4-055 (prohibiting sound-emitting devices audible
    to others on public conveyances); § 8-4-140 (prohibiting
    intentional injury to or obstruction of signal systems);
    § 8-4-065 (prohibiting the intentional interference with
    utility equipment); § 8-4-081 (prohibiting public urina-
    tion or defecation). The City intends Subsection D to
    augment law enforcement’s authority under the Municipal
    Code, empowering it to address inconveniences created
    by three or more individuals not only by confronting
    them, but also by dispersing anyone nearby—a tactic
    that pertains in equal force to individuals exercising
    No. 11-2408                                               23
    protected First Amendment rights. But unlike the Munici-
    pal Code’s treatment of nuisances, and likely in an
    attempt to maximize flexibility and discretion for law
    enforcement, Subsection D does not specify what incon-
    veniences, if performed by three or more individuals,
    may trigger an order to disperse. Nor does it clarify
    that, whatever the inconvenience at issue, dispersal
    must be necessary to confront the violation. To this end,
    the ordinance lacks the necessary specificity and tailoring
    to pass constitutional muster, and we must conclude
    that the ordinance substantially impacts speech. See
    Broadrick, 
    413 U.S. at 615
    .
    The Supreme Court has held that when individuals
    ordered to disperse or move along manifest a “bona fide
    intention to exercise a constitutional right,” a city may
    criminalize their refusal only when its “interest so
    clearly outweighs the [individuals’] interest sought to
    be asserted that the latter must be deemed insubstan-
    tial.” Colten v. Kentucky, 
    407 U.S. 104
    , 111 (1972). A city’s
    interest prevails only if the nuisances at issue risk sub-
    stantial harm or if dispersal is otherwise necessary
    to address the violations and transgressors. See Wash.
    Mobilization Comm. v. Cullinane, 
    566 F.2d 107
    , 118-19
    (D.C. Cir. 1977) (considering an ordinance com-
    manding “every person present at the scene of [a public
    disturbance] [to] comply with any necessary order or
    instruction of any police officer” and holding that the
    word “necessary” limited “police discretion to the ac-
    complishment of the specified and properly narrow
    purposes of the regulation”). As the Court emphasized
    in Cox v. Louisiana:
    24                                               No. 11-2408
    The constitutional guarantee of liberty implies the
    existence of an organized society maintaining public
    order, without which liberty itself would be lost in
    the excesses of anarchy. The control of travel on
    the streets is a clear example of governmental responsi-
    bility to insure this necessary order. A restriction
    in that relation, designed to promote the public con-
    venience in the interest of all, and not susceptible to
    abuses of discriminatory application, cannot be disre-
    garded by the attempted exercise of some civil
    right which, in other circumstances, would be
    entitled to protection.
    
    379 U.S. 536
    , 553-55 (1965) (emphasis added). A law
    insuring public safety and security is not susceptible
    to abuses of discriminatory application when the
    behavior it targets is clear and the law enforcement
    action it authorizes is necessary to its success. Ac-
    cordingly, law enforcement may disperse individuals
    present only when its ability to control public nuisances
    or obstruction demand that tactic. Cf. Boos, 
    485 U.S. at
    330-
    32 (declining to find overly broad an ordinance
    criminalizing an individual’s refusal to obey a dispersal
    order within 500 feet of an embassy because the law,
    as construed, permitted dispersal “only when the police
    reasonably believe[d] that a threat to the security or
    peace of the embassy [was] present”). Even if the term
    “serious inconvenience” were better defined, which it
    is not, permitting dispersal when a serious incon-
    venience may be alternatively controlled, as does Sub-
    section D, does not meet this standard and im-
    properly reaches otherwise protected expression. Cf.
    No. 11-2408                                              25
    Leonardson v. City of East Lansing, 
    896 F.2d 190
    , 197-98
    (6th Cir. 1990).
    3. Dispersal on the Basis of Likely Alarm
    With respect to the undesirable effect of “alarm,” we
    reiterate our conclusion in United States v. Woodard that
    this term is “conjugate with the term ‘breach of the
    peace,’ which may encompass the reaction of disturbance
    and alarm on the part of others.” 
    376 F.2d at 141
    . We
    consequently understand “alarm” as conjugate with the
    term “disorderly conduct” as well. See Chicago Municipal
    Code § 8-4-010(a), (d); see also supra note 4. Generally,
    we avoid construing statutes “in a way that makes
    words or phrases meaningless or superfluous.” United
    States v. Chemetco, Inc., 
    274 F.3d 1154
    , 1160 (7th Cir.
    2001) (quoting United States v. Franz, 
    886 F.2d 973
    , 978
    (7th Cir. 1989)) (internal quotation marks and omissions
    omitted). As used in Subsection D, however, the term
    “alarm”cannot escape this fate. “Alarm” denotes “sud-
    den apprehension and fear resulting from the percep-
    tion of immediate danger.” See M ERRIAM-W EBSTER D IC-
    TIONARY O NLINE, available at http://merriam-webster.
    com/dictionary (last visited August 2, 2012) (defining
    “alarm”). The Illinois Supreme Court has clarified that, for
    purposes of our analysis, the immediate danger (dis-
    orderly conduct) one perceives as alarming may not
    be offensive ideas or language only; therefore, the disor-
    derly conduct engendering the alarm at issue must be a
    corporeal disturbance to which a viewer may react. See
    Woodard, 
    376 F.2d at 141
     (noting that actions provoke a
    26                                              No. 11-2408
    breach of the peace or amount to disorderly conduct when
    they are contrary to “ordinary human conduct” and
    “offend the mores of the community”). In other words, the
    alarmed response derives from conduct likely to result
    in substantial harm or serious inconvenience, as acts of
    this nature are those likely to manifest danger. The term
    “alarm” thus proves redundant, reiterating that law
    enforcement may criminalize a failure to disperse
    when confronted with the likely outcome of substantial
    harm or serious inconvenience. “Alarm” does not
    subsume within Subsection D any additional speech;
    the term renders Subsection D overly broad only to the
    extent that the terms “substantial harm” or “serious
    inconvenience” do so.
    As we discussed, however, law enforcement may con-
    stitutionally order dispersal of those engaged in pro-
    tected expression upon “serious inconvenience” only
    when dispersal is required to combat the specified nui-
    sances before it. See supra Part II.C.2. Just as Subsection D
    lacks this circumscription with respect to dispersal
    orders on the basis of “serious inconvenience,” so, too,
    with respect to dispersal orders on the basis of “alarm.”
    4. Dispersal on the Basis of Likely Annoyance
    As for dispersal orders on the sole basis of “annoyance,”
    Subsection D again cannot withstand constitutional
    scrutiny. Unlike conduct likely to elicit alarm, disorderly
    conduct likely to engender annoyance is not only those
    actions that cause substantial harm or serious inconve-
    nience. The ordinary meaning of “to annoy,” which is “to
    No. 11-2408                                                   27
    trouble, to vex, to impede, to incommode, to provoke,
    to harass or to irritate,” Coates, 402 U.S. at 613, compels
    this reading: not every annoying act gives rise to im-
    minent danger or nuisance.
    Avoiding annoyance is never a proper basis on which
    to curtail protected speech. See Coates, 402 U.S. at 615
    (“The First and Fourteenth Amendments do not
    permit a State to make criminal the exercise of the right
    of assembly simply because its exercise may be ‘annoy-
    ing’ to some people.”). This precept is most obvious when
    the speech or assembly is the source of the annoyance
    because, as the Supreme Court emphasized in Coates v.
    Cincinnati, silencing otherwise protected speech because it
    annoys is tantamount to “suspending unconditionally the
    right of assembly and free speech.” Id. at 616; see also
    Terminiello, 
    337 U.S. at 4
     (“[A] function of free speech . . . is
    to invite dispute. . . . Speech is often provocative and
    challenging. It may strike at prejudices and preconceptions
    and have profound unsettling effects as it presses for
    acceptance of an idea.”). We do not diminish First Amend-
    ment protection when, per the Illinois Supreme Court’s
    construction, speech or assembly is not the source of the
    annoyance in question. We cannot conceive of an
    annoying behavior, however annoying it may be, that
    could constitutionally draw as a remedy dispersing
    others engaged in protected speech. Cf. Hill, 
    482 U.S. at 465
     (“[W]e have repeatedly invalidated laws that
    provide the police with unfettered discretion to arrest
    individuals for words or conduct that annoy or offend
    them.”).
    28                                             No. 11-2408
    In sum, we hold that to the extent Subsection D permits
    dispersal orders against people exercising First Amend-
    ment rights (1) when those around them are likely to
    foster serious inconvenience or alarm, but dispersal is not
    integral to law enforcement’s ability to control the nui-
    sances, and (2) when they or those around them are
    likely to foster annoyance, the ordinance substantially
    encumbers protected expression vis-à-vis its legitimate
    scope. See Broadrick, 
    413 U.S. at 615
     (“[T]he overbreadth
    of a statute must not only be real, but substantial as
    well.”). While recognizing and respecting the City’s
    need to protect its citizens and its streets, we conclude
    that the ordinance is overly broad.
    D. Fourteenth Amendment Challenge: Void for Vague-
    ness
    Subsection D satisfies due process only if it “define[s]
    the criminal offense (1) with sufficient definiteness that
    ordinary people can understand what conduct is prohib-
    ited and (2) in a manner that does not encourage
    arbitrary and discriminatory enforcement.” Skilling, 130
    S. Ct. at 2927-28 (quoting Kolender, 
    461 U.S. at 357
    ).
    Having upheld as constitutional the ordinance’s defini-
    tion of “disorderly conduct,” see supra note 4, we con-
    sider only whether the phrase “which acts are likely
    to cause substantial harm or serious inconvenience,
    annoyance or alarm” comports with due process’ com-
    mands.
    No. 11-2408                                           29
    1. Sufficient Definiteness
    The Illinois Supreme Court has clarified that conduct
    which Subsection D does not proscribe: failure to
    disperse when all that transpires is peaceful speech or
    assembly. See In re B.C., 
    680 N.E.2d at 1369
    ; Raby, 
    240 N.E.2d at 598
    . We must assess, however, whether the
    ordinance makes clear that conduct which does give
    rise to a lawful dispersal order such that an ordinary
    individual can understand when his failure to move
    is criminalized. As we do so, we consider not only the
    words of the ordinance, but also the context for which
    the statute is written. See Grayned v. City of Rockford,
    
    408 U.S. 104
    , 112 (1972) (noting that an ordinance’s
    “particular context” may “give[] fair notice to those to
    whom it is directed” (quoting Am. Commc’ns Ass’n v.
    Douds, 
    339 U.S. 382
    , 412 (1950))).
    In the context of a disorderly conduct ordinance, the
    terms “substantial harm,” “serious inconvenience,” and
    “alarm” specify what types of disorderly conduct will
    trigger a lawful dispersal order. “Substantial harm,” as
    we mentioned, signifies imminent property damage or
    violence. See supra Part II.C.1. An individual can under-
    stand that when the conduct of three or more people in
    the vicinity will likely result in the immediate destruc-
    tion of property or physical injury, that conduct will
    trigger a dispersal order and his compliance is required.
    Regarding dispersal on the basis of “serious inconve-
    nience,” the term, without further explanation or refine-
    ment, does not identify what nuisances amount to such
    inconvenience that First Amendment rights constitution-
    30                                           No. 11-2408
    ally give way to Subsection D’s restrictions. See supra
    Part II.C.2. Without greater specificity, the ordinance
    denies individuals of common comprehension notice of
    the prohibited conduct. One lacks warning about the
    behavior that prompts a lawful dispersal order, and he
    cannot know when he must move along if so ordered
    by law enforcement.
    The term “alarm,” as used in Subsection D, remains
    coextensive with the terms “substantial harm” and
    “serious inconvenience.” See supra Part II.C.3. Bounded
    by these effects, the term is superfluous and does not
    criminalize any additional behavior. Nevertheless, due
    to its symbiotic relationship with the terms “substantial
    harm” and “serious inconvenience,” it suffers from what-
    ever imprecision afflicts them. “Alarm,” therefore, fails
    to advance notice to the extent that “serious inconve-
    nience” fails to do so.
    Finally, to the extent that the ordinance criminalizes
    one’s refusal to disperse when proximate to disorderly
    conduct likely to annoy, it predicates penalty on an
    inscrutable standard, which is no standard at all. See
    Coates, 402 U.S. at 614. Assuming arguendo that
    annoying behavior may constitute disorderly conduct,
    see Woodard, 
    376 F.2d at 141
     (noting that behavior that
    is simply “eccentric or unconventional” typically falls
    outside the bounds of disorderly conduct, “no matter
    how irritable to others”), reasonable people may disagree
    about what actions evoke this reaction. See Coates, 402
    U.S. at 614 (“Conduct that annoys some people does not
    annoy others.”). As a result, “[individuals] of common
    No. 11-2408                                                31
    intelligence must necessarily guess at [what it means to
    annoy].” Id. (quoting Connally v. Gen. Constr. Co., 
    269 U.S. 385
    , 391 (1926)). The ordinance, therefore, runs afoul
    of due process’ first requirement, see Skilling, 
    130 S. Ct. at 2927-28
    , because individuals who wish to comply with
    Subsection D lack notice about what annoying
    conduct may legitimately invite a dispersal order.
    2. Arbitrary or Discriminatory Enforcement
    Subsection D may also be void for vagueness if it is
    susceptible to discriminatory or arbitrary enforcement.
    The ordinance fails this second criterion if it impermis-
    sibly delegates to law enforcement the authority to
    arrest and prosecute on “an ad hoc and subjective ba-
    sis.” Grayned, 
    408 U.S. at 108
    ; see also Cox, 
    379 U.S. at
    555-
    56 (invalidating convictions for violating an ordinance
    prohibiting the obstruction of public passages because
    of the law’s routine, discriminatory enforcement). We
    underscore, however, that a statute is not vague simply
    because it requires law enforcement to exercise some
    degree of judgment. See Grayned, 
    408 U.S. at 114
    .
    To the contrary, due process rejects “sweeping
    standard[s] [that] place[] unfettered discretion in the
    hands of police, judges, and juries to carry out arbitrary
    and erratic arrests and convictions.” Wright v. New Jersey,
    
    469 U.S. 1146
    , 1151 (1985) (quoting Papachristou v. City
    of Jacksonville, 
    405 U.S. 156
    , 162 (1972)) (internal quota-
    tion marks omitted).
    When law enforcement confronts a likelihood of “sub-
    stantial harm,” dispersal orders avoid this defect. Sub-
    32                                             No. 11-2408
    stantial harm as a trigger curtails law enforcement’s
    dispersal authority, limiting its power to situations in
    which imminent property damage or violence prove
    readily apparent. Such restriction ensures that, with
    respect to this trigger, Subsection D does not facially
    encourage standardless decision-making and enforce-
    ment at odds with due process.
    We conclude, however, that empowering law enforce-
    ment to order dispersal when faced with the likelihood
    of “serious inconvenience” is not immune from arbitrary
    application. We recognize that predicating law enforce-
    ment’s power on at least three people’s behavior adds
    definition and heft to the ordinance’s “likelihood” lan-
    guage, heightening the required probability of inconve-
    nience before Subsection D may be invoked and limiting
    when dispersal may be ordered. The ordinance does
    not, however, limit dispersal authority to situations in
    which dispersal is necessary to ensure the City’s safety
    and order. See supra Part II.C.2. To that end, Subsection D
    “allows an unrestricted delegation of power, which[,]
    ‘in practice leaves the definition of its terms to law en-
    forcement officers, and thereby invites arbitrary, dis-
    criminatory[,] and overzealous enforcement.’ ” Leonardson,
    
    896 F.2d at 198
     (quoting Cullinane, 
    566 F.2d at 117
    ). The
    ordinance permits law enforcement too much discretion
    in determining when addressing a nuisance permits
    quieting protected expression and when it does not.
    Moreover, dispersal orders on the basis of “alarm,” when
    the alarm coincides with the likelihood of serious incon-
    venience, suffers the same infirmity.
    No. 11-2408                                                 33
    Finally, permitting dispersal orders when con-
    fronted with “annoyance” alone invites unbridled discre-
    tion at odds with the Fourteenth Amendment. The
    relative, and thus standardless, nature of annoyance
    renders individuals vulnerable to arbitrary or discrim-
    inatory arrest under Subsection D, failing to fulfill
    due process’ second command. See Skilling, 
    130 S. Ct. at 2927-28
    . Accordingly, we conclude that Subsection D
    is void for vagueness.
    E. Subsection D’s Total Invalidation is Inappropriate
    As facial failings, overbreadth and vagueness render
    a law totally invalid. Where, however, constitutional
    overbreadth or vagueness may be cured, “ ‘partial, rather
    than facial, invalidation is the required course,’ such
    that a ‘statute may . . . be declared invalid to the extent
    that it reaches too far, but otherwise left intact.’ ” Ayotte
    v. Planned Parenthood of N. New England, 
    546 U.S. 320
    ,
    329 (2006) (quoting Brockett v. Spokane Arcades, Inc., 
    472 U.S. 491
    , 504 (1985)).
    As it assesses a law’s candidacy for partial invalida-
    tion, a court may not invoke its remedial powers to
    “circumvent the intent of the legislature.” Id. at 330.
    “Partial invalidation may not be possible . . . if the legisla-
    ture would not have passed the law without the uncon-
    stitutional element, or if the statute lacks a severability
    clause and the only way to remove the unconstitutional
    element is total abrogation of the statute.” Commodity
    Trend Serv. v. Commodity Futures Trading Comm’n, 149
    34                                              No. 11-
    2408 F.3d 679
    , 688 n.4 (7th Cir. 1998) (citing Brockett, 
    472 U.S. at 506
    ).
    As acknowledged in oral argument, Bell does not chal-
    lenge Subsection D’s constitutionality to the extent that
    it legitimizes dispersal when three or more people
    are engaged in disorderly conduct likely to cause “sub-
    stantial harm.” Additionally, we are confident, based on
    the City’s representations to us, that it would prefer a
    statute that permits dispersal on the basis of “substantial
    harm” alone to no statute at all. See Ayotte, 
    546 U.S. at 330
    . We may, therefore, decline to invalidate Subsection D
    in toto without invading the province of a legislature
    or impinging upon principles of federalism. The City
    may criminalize one’s failure “to obey a lawful order
    of dispersal by a person known by him to be a peace
    officer under circumstances where three or more
    persons are committing acts of disorderly conduct in
    the immediate vicinity, which acts are likely to cause
    substantial harm.” Chicago Municipal Code § 8-4-010(d).
    As for the remainder of Subsection D, the ordinance
    may be rewritten or construed to avoid facial uncon-
    stitutionality. The City may, for example, amend the
    ordinance so that it applies only when dispersal is neces-
    sary to redress an observable, specific nuisance. Further-
    more, the City may, as is needed to save the ordinance,
    abandon altogether dispersal orders on the basis of an-
    noyance. Though these revisions are not overly complex,
    they are the City’s to make. We leave to the City the
    right to remedy its ordinance as it sees fit, see Am. Book-
    sellers Ass’n, 
    484 U.S. at 397
    , restraining ourselves from
    No. 11-2408                                            35
    a “serious invasion of the legislative domain,” Ayotte,
    
    546 U.S. at 330
    . We decline to rewrite Subsection D, and
    we find the following unconstitutional: “or serious incon-
    venience, annoyance, or alarm.” Chicago Municipal
    Code § 8-4-010(d).
    III. Conclusion
    For the foregoing reasons, we R EVERSE the judgment
    of the district court and R EMAND for further proceedings
    consistent with this opinion.
