At issue in this case is whether Michigan State University (MSU) Ordinance, § 15.05 is facially unconstitutional. The Court of Appeals reversed the circuit court’s conclusion that the ordinance is unconstitutional under City of Houston, Texas v Hill, 482 US 451; 107 S Ct 2502; 96 L Ed 2d 398 (1987).1 Because we agree with the circuit court’s analysis and conclude that the language in the ordinance making it an offense to “disrupt the normal activity” of a protected person is facially overbroad, as articulated by the United States Supreme Court in Hill, we reverse the portion of the Court of Appeals’ judgment pertaining to the constitutionality of MSU Ordinance, § 15.05, and we reinstate the circuit court’s decision with regard to this issue to the extent that the circuit court held that the quoted language is facially unconstitutional.

Also at issue is whether MCR 7.101(0) provides for taxation of costs in criminal cases. The Court of Appeals held that costs may not be assessed under MCR 7.101(0) *71in criminal matters.2 We agree with the Court of Appeals and, therefore, affirm that portion of its judgment.

I. FACTS AND PROCEDURAL HISTORY

This case arises from a parking citation that defendant received when his car was parked in an MSU parking structure. On the day the citation was issued, MSU parking enforcement employee Ricardo Rego was working on campus. Defendant confronted Rego and asked if Rego was the one who had issued the citation. Defendant was shouting, which led Rego to believe that defendant was acting aggressively. Rego got into his service vehicle and called the campus police.3 Approximately 10 to 15 minutes passed before the police arrived. During that time, Rego sat in his service vehicle and completed the process for having an adjacent vehicle towed, while defendant stood outside the service vehicle and took pictures of Rego with a camera phone.

Defendant was charged with the misdemeanor offense of violating MSU Ordinance, § 15.05.4 A district court jury convicted defendant of violating the ordinance. On appeal, the circuit court reversed the conviction on the basis that the ordinance was unconstitutionally overbroad on its face. The circuit court also granted defendant’s motion brought pursuant to MCR 7.101(0) to tax costs against the prosecution.

*72The Court of Appeals reversed the circuit court’s decision and held that the ordinance is not facially overbroad, and defendant is not entitled to costs.5 This Court granted defendant’s application for leave to appeal and asked the parties to address “(1) whether Michigan State University Ordinance 15.05 is facially unconstitutional under City of Houston v Hill, 482 US 451 (1987), and (2) whether MCR 7.101(0) allows taxation of costs in criminal cases appealed in the circuit court.”6

II. STANDARD OF REVIEW

This Court reviews de novo questions of constitutional law.7 This Court presumes that ordinances are constitutional, and the party challenging the validity of the ordinance has the burden of proving a constitutional violation.8

III. ANALYSIS

We first address whether MSU Ordinance, § 15.05 is facially unconstitutional.9 When considering a “facial” challenge to the breadth of a law on First Amendment grounds,10 this Court considers “not merely the spo*73radie abuse of power by the censor but the pervasive threat inherent in its very existence that constitutes the danger to freedom of discussion.”11

Before ruling that a law is unconstitutionally over-broad, this Court must determine whether the law “reaches a substantial amount of constitutionally protected conduct.”12 The United States Supreme Court has held that criminal statutes must be scrutinized with particular care,13 and those that prohibit a substantial amount of constitutionally protected conduct may be facially overbroad even if they have a legitimate application.14 However, “invalidating a law that in some of its applications is perfectly constitutional — particularly a law directed at conduct so antisocial that it has been made criminal — has obvious harmful effects.”15 Thus, a statute’s overbreadth must “be substantial, not only in an absolute sense, but also relative to the statute’s plainly legitimate sweep.”16

In Hill, the United State Supreme Court considered the constitutionality of an ordinance that made it *74unlawful to “in any manner oppose, molest, abuse or interrupt” a police officer.17 The Court concluded at the outset that this language prohibited verbal interruptions and, therefore, implicated constitutionally protected speech under the First Amendment.18 The Court first noted that the ordinance was not limited in any way to fighting words or obscene language.19 Instead, the ordinance imposed a blanket prohibition on speech that interrupts an officer in any manner.20 Expressly clarifying that the Constitution prohibits making such speech a crime, the Court explained that “[t]he freedom of individuals verbally to oppose or challenge police action without thereby risking arrest is one of the principal characteristics by which we distinguish a free nation from a police state.”21 While the Court acknowledged the difficulty of drafting precise laws, it reiterated that it would invalidate those laws “that provide the police with unfettered discretion to arrest individuals for words or conduct that annoy or offend them.”22

Hill also stated that as the Court had “observed over a century ago, ‘[i]t would certainly be dangerous if the legislature could set a net large enough to catch all *75possible offenders, and leave it to the courts to step inside and say who could be rightfully detained, and who should be set at large.’ ”23 The Court noted that the ordinance’s plain language prohibiting opposing, molesting, abusing, or interrupting a police officer in any manner could be violated on numerous occasions every day.24 Nevertheless, only those individuals that the police chose to arrest would be charged with violating the ordinance.25 Hill concluded that because the “ordinance criminalizes a substantial amount of constitutionally protected speech, and accords the police unconstitutional discretion in enforcement,” it was substantially overbroad and facially invalid.26

In this case, we address the constitutionality of MSU Ordinance, § 15.05, which provides:

No person shall disrupt the normal activity or molest the property of any person, firm, or agency while that person, firm, or agency is carrying out service, activity or agreement for or with the University.

“The first step in overbreadth analysis is to construe the challenged statute” because “it is impossible to determine whether a statute reaches too far without first knowing what the statute covers.”27 This ordinance makes it a crime to “disrupt the normal activity ... of any person, firm, or agency.. . carrying out service, activity or agreement for or with the University.” Defendant argues that this language is facially overbroad because it substantially infringes on First Amendment *76rights. We agree with defendant and hold that the phrase “disrupt the normal activity” in the ordinance is facially overbroad.28

The MSU ordinance prohibits disruptions but does not specify the types of disruptions that are prohibited. Thus, the plain language of the ordinance allows its enforcement for even verbal disruptions. Moreover, like the ordinance that the United States Supreme Court invalidated in Hill, the verbal disruptions that the MSU ordinance criminalizes are not limited to those containing fighting words or obscene language. Instead, the MSU ordinance explicitly criminalizes any disruption of the normal activity of persons or entities carrying out activities for or with MSU. Not only does the ordinance fail to limit the types of disruptions that are prohibited, it also protects a much broader class of individuals than the ordinance at issue in Hill. The plain language of this ordinance allows it to be enforced against anyone who disrupts in any way anyone carrying out any activity for or with MSU. Like the ordinance in Hill, which was “admittedly violated scores of times daily,”29 the MSU ordinance could be violated numerous times throughout any given day given that there are seem*77ingly infinite ways in which someone might “disrupt” another who is engaged in an “activity” for or with MSU. Thus, we believe that this ordinance, just like the ordinance in Hill, “criminalizes a substantial amount of constitutionally protected speech . . . .”30

The Court of Appeals found Hill distinguishable from this case because the Hill ordinance specifically protected police officers who have the power to arrest violators at the officers’ discretion, while the MSU ordinance only prohibits the disruption of MSU employees who do not necessarily have the power to arrest violators.31 We disagree with this distinction. The MSU ordinance prohibits the disruption of MSU police officers while they are carrying out their duties for the university, and those police officers have the explicit power to enforce the ordinance and arrest violators.32 Thus, the concerns that Hill had regarding “[t]he freedom of individuals verbally to oppose or challenge *78police action without thereby risking arrest” apply equally to the MSU ordinance.33

Moreover, the distinction regarding whether an individual protected by the ordinance has the power to arrest is an irrelevant one. An MSU student, for example, enrolled in classes on campus is undoubtedly carrying out an activity with MSU and, therefore, is protected by the ordinance. Nothing in the plain language of the ordinance prevents a student who simply feels that he or she has been disrupted by the actions or words of another person from seeking enforcement of this ordinance. Nor does the ordinance language prevent a police officer from choosing to enforce the ordinance when there is a complaint or simply when the officer witnesses somebody disrupting another person’s activity.34 While not all protected individuals have the same power as a police officer to arrest, the ordinance is nonetheless a criminal statute that subjects the violator to a misdemeanor conviction and provides someone who does have the power to arrest with the opportunity to do so whenever a protected individual is *79disrupted.35 Accordingly, this ordinance can be said to “provide the police with unfettered discretion to arrest individuals for words or conduct that annoy or offend them,” just as the ordinance in Hill did.36 Thus, like the unconstitutional ordinance in Hill, the MSU ordinance is “susceptible of regular application to protected expression,” regardless of whether the protected individual has the power to arrest.37

The Court of Appeals further attempted to distinguish Hill because the ordinance in that case used the word “interrupt,” while the MSU ordinance uses the word “disrupt.”38 The American Heritage Dictionary of the English Language (2006), quoted by the Court of Appeals, defines “disrupt” as “[t]o throw into confusion or disorder” or “[t]o interrupt or impede the progress, movement, or procedure of[.]”39 The Court of Appeals reasoned that a person can “interrupt an action without causing disorder or confusion, such as by merely asking a question,” but “the same conduct does not necessarily *80disrupt.. . ,”40 The Court of Appeals then explained that its reasoning compelled the conclusion that while the term “interrupt” used in the Hill ordinance may encompass a substantial amount of constitutionally protected conduct, “the same can not necessarily be said” of the term “disrupt” used in the MSU ordinance.41 We disagree with this analysis.

Under the definition chosen by the Court of Appeals, “disrupt” explicitly includes “interrupt.” Other dictionaries similarly include “interrupt” in the definition of “disrupt.”42 Moreover, the terms “interrupt” and “disrupt” are commonly used as synonyms.43 Nevertheless, the Court of Appeals’ reasoning implies that the term “interrupt” is capable of encompassing verbal interruptions, thereby implicating constitutionally protected conduct, while the term “disrupt” is somehow limited to nonverbal acts and thereby incapable of reaching protected conduct. However, nothing in the ordinary meanings of “interrupt” and “disrupt” supports this reasoning. More importantly, nothing in the ordinances at issue in Hill or this case creates that distinction.

The dictionary definition used by the Court of Appeals essentially provides that a person can “disrupt” *81another person by either (1) interrupting that person or (2) causing disorder or confusion.44 Given this definition, one way to violate the MSU ordinance is to disrupt a person by interrupting that person. There is no question that the United States Supreme Court concluded in Hill that an ordinance broadly prohibiting interruptions reaches “a substantial amount of constitutionally protected speech . .. .”45 A person may also violate the MSU ordinance, under this definition of “disrupt,” by causing disorder or confusion. This means that if a person asks another person several questions, which causes that other person’s activity to be “thrown into confusion or disorder,” a prohibited disruption has occurred. Both ways in which a person may disrupt another person can be accomplished by purely expressive conduct.46 And regardless of which definition of *82“disrupt” is applied, the MSU ordinance can be used to reach and criminalize “a substantial amount of constitutionally protected conduct.”47

Finally, we note that our analysis is not affected by Hill’s observation of an anomaly in Texas law whereby the ordinance in that case was preempted to the extent that the Texas Penal Code already covered the proscribed conduct. Because Texas law preempted enforce*83ment of that portion of the Hill ordinance that criminalized someone who “assault[s]” or “strike[s]” a police officer, “the enforceable portion of the ordinance” made it “ ‘unlawful for any person to .. . in any manner oppose, molest, abuse or interrupt any policeman in the execution of his duty,’ and thereby prohibits verbal interruptions of police officers.”48

While defendant does not offer any Michigan law similar to the Texas preemption statute, we note that separate statutes and MSU ordinances already criminalize physical assaults. For instance, MSU Ordinance, § 22.01 provides that “[n]o person shall accost, molest, or harass any person upon the lands governed by the Board [of Trustees].” And, of course, MCL 750.81 criminalizes all assaults that occur within the state, regardless of whether they occur on MSU grounds. Thus, for all practical purposes, the only disruptions that the MSU ordinance newly criminalizes are the same nonphysical ones that the enforceable portion of the Hill ordinance proscribed. In other words, just as Texas law criminalized physical assaults on police offic*84ers in the absence of the Hill ordinance, state statutes and MSU ordinances already criminalize any physical assault that disrupts someone on the MSU campus even in the absence of MSU Ordinance, § 15.05.49 As a result, the partial preemption of the Hill ordinance does not compel a different result in this case.

Accordingly, we hold that under Hill, the language in MSU Ordinance, § 15.05 making it an offense to “disrupt the normal activity” of a protected person is facially unconstitutional.

Next, we address whether MCR 7.101(0) allows taxation of costs in criminal appeals in the circuit court. MCR 7.101(0) provides:

Costs in an appeal to the circuit court may be taxed as provided in MCR 2.625. A prevailing party may tax only the reasonable costs incurred in the appeal, including:

(1) the cost of an appeal or stay bond;

(2) the transcript;

(3) documents required for the record on appeal;

(4) fees paid to the clerk or to the trial court clerk incident to the appeal;

*85(5) taxable costs allowed by law in appeals to the Supreme Court (MCL 600. 2441); and

(6) other expenses taxable under applicable court rules or statutes.

Defendant argues that he is entitled to reimbursement for the costs he incurred because the prosecution pursued its case against him on the basis of an unconstitutional statute. While the circuit court granted defendant’s motion for taxation of costs, the Court of Appeals reversed that decision on the basis that there is no statutory authority allowing the assessment of costs in this matter. We agree with the Court of Appeals’ analysis of this issue.

MCR 7.101(0) explicitly states that “costs . . . maybe taxed as provided in MCR 2.625.” MCR 2.625 is a rule of civil procedure, which does not apply to a criminal matter.50 MCR 7.101(O)(5) refers to MCL 600.2441, a statute that applies only to the taxation of costs in civil matters.51 Because this case is a criminal matter, MCR 7.101(0) does not provide grounds for awarding costs.52 *86Accordingly, the Court of Appeals correctly concluded that there is no basis to “undermine the broad statutory discretion granted the prosecution in its charging decisions,”53 and the assessment of costs against the prosecution in this case was improper.

IV CONCLUSION

We conclude that the language in MSU Ordinance, § 15.05 making it an offense to “disrupt the normal activity” of a protected person is facially overbroad, as articulated by the United States Supreme Court in Hill. Therefore, we reverse the judgment of the Court of Appeals in part and reinstate the circuit court’s decision to the extent that the circuit court held that the quoted language is facially unconstitutional. On the issue of costs, we agree with the Court of Appeals’ conclusion that the circuit court erroneously assessed costs against the prosecution and, therefore, we affirm the Court of Appeals’ judgment in part.

(dissenting). I respectfully dissent from the majority’s conclusion that the language in Michigan State University (MSU) Ordinance, § 15.05 that makes it an offense to “disrupt the normal activity” of a protected person is unconstitutional under City of Houston, Texas v Hill.1 Significantly, the issue of whether the ordinance was unconstitutionally applied *87to defendant for engaging in protected expression is not before this Court. Addressing defendant’s facial challenge, the majority concludes that the overbreadth of the ordinance is so substantial that it must be struck down. The decision to strike down the instant ordinance, and thereby nullify a decision of the university’s legislative body, is a matter of considerable consequence. This Court is responsible for upholding both the Michigan and federal constitutions, but its authority to invalidate laws is limited and must be predicated on a clear and apparent demonstration of unconstitutionality. Absent that demonstration, the majority’s decision, in my judgment, is an expansion of judicial power and an unwarranted encroachment on the legislative branch of government.

In my view, Hill does not provide sufficient grounds to conclude that MSU Ordinance, § 15.05 reaches a substantial amount of constitutionally protected expression relative to its plainly legitimate sweep. I am also not convinced that the ordinance presents a realistic danger of significantly compromising First Amendment freedoms. Finally, the majority fails to consider the context of the academic environment in reaching its decision. I would affirm the judgment of the Court of Appeals upholding MSU Ordinance, § 15.05 as constitutional on its face and remanding the case to the trial court for consideration of defendant’s as-applied challenge.2

I. THE OVERBREADTH DOCTRINE

Laws are presumed constitutional, and this Court *88must construe a law as constitutional unless its unconstitutionality is clearly apparent.3 The burden of proving that a law is unconstitutional falls on the party bringing the challenge.4

Facial overbreadth, as alleged here, is a unique breed of constitutional challenge because of the competing social costs at issue.5 The first concern is that the threat of enforcement of an overbroad law may have a chilling effect on protected expression, which is harmful because it deprives society of an uninhibited marketplace of ideas.6 The fear is that the law’s “very existence may cause others not before the court to refrain from constitutionally protected speech or expression.”7 To address this concern, the overbreadth doctrine allows parties to challenge laws without establishing the traditional standing requirements.8 That is, it “allows a party to challenge a law written so broadly that it may inhibit the constitutionally protected speech of third parties, even though the party’s own conduct may be unprotected.”9 Accordingly, “[t]he overbreadth doctrine is an exception to the traditional rule of practice that ‘a *89person to whom a statute may constitutionally be applied will not be heard to challenge that statute on the ground that it may conceivably be applied unconstitutionally to others, in other situations not before the court.’ ”10

“The consequence of our departure from traditional rules of standing in the First Amendment area is that any enforcement of a statute thus placed at issue is totally forbidden until and unless a limiting construction or partial invalidation so narrows it as to remove the seeming threat or deterrence to constitutionally protected expression.”11 The competing social cost of the overbreadth doctrine, therefore, is that it prevents a law from applying to constitutionally unprotected speech and even constitutionally unprotected conduct, which can result in obvious harm to society.12 Accordingly, “[i]n order to maintain an appropriate balance, we have vigorously enforced the requirement that a statute’s overbreadth be substantial, not only in an absolute sense, but also relative to the statute’s plainly legitimate sweep.”13 Further, to invalidate a law, “there must be a realistic danger that the statute itself will significantly compromise recognized First Amendment protections of parties not before the Court. . . .”14 Invalidation for overbreadth is “strong medicine” that should be used “sparingly and only as a last resort” and not “when a limiting construction has been or could be placed on the challenged statute.”15

*90II. DEFENDANT FAILS TO DEMONSTRATE THAT THE ORDINANCE REACHES A SUBSTANTIAL AMOUNT OF PROTECTED EXPRESSION

In Hill, the Court struck down as facially overbroad a Houston ordinance making it “ ‘unlawful for any person to assault, strike or in any manner oppose, molest, abuse or interrupt any policeman in the execution of his duty, or any person summoned to aid in making an arrest.’ ”16 In contrast, MSU Ordinance, § 15.05 states, “No person shall disrupt the normal activity or molest the property of any person, firm, or agency while that person, firm, or agency is carrying out service, activity or agreement for or with the University.”17 In my view, the text of the Houston ordinance and the Supreme Court’s stated reasons for striking it down are sufficiently distinguishable from this case that Hill, the sole basis for defendant’s challenge, does not support the majority’s conclusion that MSU Ordinance, § 15.05 reaches a substantial amount of protected expression.

The majority’s use of Hill to guide its analysis is problematic in the first instance because it effectively turns the presumption of constitutionality on its head. Although the majority states that it “presumes that ordinances are constitutional,”18 its analysis uses a case in which an ordinance was declared unconstitutional as a point of reference and from there reasons that no basis exists for not treating that case as controlling. The majority’s analysis suggests a presumption of unconstitutionality. The majority’s reliance on Hill is also problematic because it allows the majority to evade a traditional overbreadth analysis in what amounts to an attempt to fit *91a square peg into a round hole. Careful review reveals that the majority’s analysis presents an oversimplified version of Hill that downplays its distinguishing aspects, creating only the appearance of a good fit.

Beginning with the most obvious distinction, the Houston ordinance made it unlawful to “interrupt” a police officer in the execution of his or her duties, whereas MSU Ordinance, § 15.05 makes it unlawful to “disrupt” the normal activity of a protected person carrying out an activity for or with MSU. Contrary to the majority’s assertion, these terms are not used in a largely synonymous fashion by those who use the English language carefully, as judges must, and the majority’s use of thesaurus references is misleading.19 The term “interrupt” is defined as “[t]o break the continuity or uniformity of,” whereas “disrupt” means “[t]o throw into confusion or disorder” or “[t]o interrupt or impede the progress, movement, or procedure of[.]”20

Significantly, the term “interrupt” typically carries a verbal connotation.21 By contrast, the term “disrupt” carries a comparatively strong connotation that suggests not merely a verbal interjection or expression of a viewpoint, but an actual and severe impediment to the carrying out of one’s activities.22 For example, in the *92context of a meeting, whereas a meeting may proceed once an interruption is over, a disruption will likely end the meeting. In my view, as this example illustrates, disruptions most often result from a nonexpressive, physical disturbance rather than the verbal interjection of a viewpoint.23 This is not to say that it is impossible for a person to disrupt the normal activity of a protected person through words or expressive conduct. Nevertheless, “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.”24

The majority, however, construes the term “disrupt” as synonymous with “interrupt,” relying primarily on its second dictionary definition, which is “[t]o interrupt or impede the progress, movement, or procedure of[.]” Using this definition, the majority concludes that MSU Ordinance, § 15.05 is comparable to the Houston ordinance because “a person can ‘disrupt’ another person by . . . interrupting that person . . . ,”25

The majority’s synthesis is not faithful to the language in the dictionary definition of “disrupt” or to MSU Ordinance, § 15.05. The second dictionary definition of “disrupt” is to interrupt the progress, interrupt the movement, or interrupt the procedure of. And MSU Ordinance, § 15.05 provides that “[n]o person shall *93disrupt the normal activity ... of [a protected person].”26 Thus, the ordinance language is focused not on disrupting the person, but on disrupting the normal activity in which the person is engaged. The following statement is a more accurate synthesis of the second dictionary definition of “disrupt” and MSU Ordinance, § 15.05: No person shall interrupt the progress, the movement, or the procedure of the normal activity of a protected person.

Interrupting the progress, the movement, or the procedure of a normal activity is a far cry from interrupting a person, and this difference indicates that MSU Ordinance, § 15.05 is less concerned with silencing speech and more concerned with allowing legitimate activities on campus to go unimpeded. The scope of the ordinance is further limited because a protected person’s “normal activity” may include being verbally interrupted by other people. It is part of a professor’s normal activity, for example, to be interrupted by students asking questions. It is likewise part of a police officer’s or a parking enforcement officer’s normal activity to be interrupted by having to respond to legitimate questions from the public. MSU Ordinance, § 15.05 does not prohibit these interruptions. The majority, having relied primarily on the second dictionary definition of “disrupt,” fails to discuss any of these subtleties or engage in any balancing analysis that takes into consideration the legitimate sweep of MSU Ordinance, § 15.05.

Applying the first dictionary definition of “disrupt,” another way to violate the ordinance is to throw into confusion or disorder the normal activity of a protected person. Certainly, a person can interrupt without throwing into confusion or disorder the normal activity *94of a protected person — for instance, by asking a question.27 Accordingly, while all disruptions may be considered interruptions (as suggested by the inclusion of “interrupt” in the second dictionary definition of “disrupt”), not all interruptions rise to the level of disruptions.28 It is also no mistake that the term “disrupt” is not included in the dictionary definition of “interrupt,” as one would expect if the terms were truly synonymous. Accordingly, the term “disrupt” carries a different meaning than “interrupt.”

Nonetheless, according to the majority, disruptions that throw into confusion or disorder the normal activity of a protected person also implicate purely expressive conduct and, therefore, MSU Ordinance, § 15.05 reaches a substantial amount of protected expression under either dictionary definition of “disrupt.” As an example, the majority asserts that “if a person asks another person several questions, which causes that other person’s activity to be ‘thrown into confusion or disorder,’ a prohibited disruption has occurred.”29 The Court in Hill, however, addressed the majority’s hypothetical example and concluded that a municipality may constitutionally punish such conduct. Specifically, the Court agreed with Justice Powell that “ ‘a municipality constitutionally may punish an individual who chooses to stand near a police officer and persistently attempt to engage the officer in conversation while the officer is directing traffic at a busy intersection.’ ”30 Stated dif*95ferently, the interruption, expressive or otherwise, is not protected if it prevents the officer from directing traffic at a busy intersection. The Court explained, however, that a municipality may not do what Houston did, which was “to attempt to punish such conduct. .. by authorizing the police to arrest a person who in any manner verbally interrupts an officer.”31 MSU Ordinance, § 15.05, however, does not make it unlawful to in any manner disrupt a protected person. Rather, a disruption is prohibited only if it prevents a protected person from carrying out an activity for or with MSU, making it narrower than the Houston ordinance.

The linguistic differences between the ordinances reveal the logical fallacy employed by the majority. In essence, the majority reasons that, because the Supreme Court held that the term “interrupt” in the Houston ordinance reached a substantial amount of protected expression, and because some interruptions rise to the level of disruptions, then the term “disrupt” in the MSU ordinance also reaches a substantial amount of protected expression. This is a non sequitur — the conclusion does not follow from the premises. Rather, all that can he drawn from Hill is that MSU Ordinance, § 15.05 reaches less protected expression than the Houston ordinance.32 This, of course, falls short of defendant’s burden to establish substantial overbreadth, and it leaves this Court with insufficient grounds to invalidate the ordinance.

Furthermore, the majority effectively ignores a major facet of the Court’s rationale in Hill for striking down *96the Houston ordinance. The Court interpreted the Houston ordinance as targeting speech and not core criminal conduct in large part because the Texas Penal Code preempted governmental subdivisions or agencies from enacting or enforcing laws that purported to criminalize any form of physical assault against a police officer, and the city conceded the issue of preemption in the Supreme Court.33 The Court stated that, as preempted, “the enforceable portion of the ordinance deals not with core criminal conduct, but with speech.”34 The Court also stated that “[t]he enforceable portion of this ordinance is a general prohibition of speech that ‘simply has no core’ of constitutionally unprotected expression to which it might be limited.”35 Indeed, given the extent of preemption, the Court went as far as to say that “limiting the ordinance to ‘physical acts’ would be equivalent to invalidating it on its face.”36 Thus, the Court construed the enforceable portion of the ordinance as prohibiting only “verbal interruptions of police officers.”37 To the extent that the ordinance prohibited nonverbal interruptions or other physical affronts directed toward police officers, the ordinance was preempted.38

*97Given this limited construction, the Court sensibly concluded that the Houston ordinance criminalized a substantial amount of protected expression relative to its plainly legitimate sweep. In this case, however, neither defendant nor the majority identifies a Michigan law that preempts MSU Ordinance, § 15.05. Accordingly, it is enforceable against physical disruptions. Because the enforceability of the ordinance is not limited to mere verbal disruptions, it has a far broader legitimate sweep than the Houston ordinance.39

The majority asserts that because existing laws “already criminalize any physical assault that disrupts someone on the MSU campus . .. , the partial preemption of the Hill ordinance does not compel a different result in this case.”40 The majority’s statement misses the point. It did not matter in Hill that Texas law already criminalized physical assaults on police officers; *98it mattered that the Texas Legislature had preempted the city from doing the same. Absent a similar preemption statute, the mere existence of MSU ordinances and statutes criminalizing certain campus disruptions does not align this case with Hill.

For all these reasons, Hill, the sole basis for defendant’s facial challenge, does not support the majority’s conclusion that MSU Ordinance, § 15.05 reaches a substantial amount of constitutionally protected expression.

III. DEFENDANT FAILS TO DEMONSTRATE A REALISTIC DANGER THAT THE ORDINANCE WILL SIGNIFICANTLY COMPROMISE FIRST AMENDMENT FREEDOMS

In addition to examining the language of an ordinance, it is appropriate to examine the likelihood of the ordinance’s unconstitutional application. Even in a facial overbreadth challenge, the party bringing the challenge must demonstrate “a realistic danger that the statute itself will significantly compromise recognized First Amendment protections of parties not before the Court... .”41 In Hill, the appellee introduced city records indicating the frequency with which arrests had been made under the Houston ordinance and the types of exchanges that had led to those arrests.42 The United States Court of Appeals for the Fifth Circuit reasoned that the evidence provided by the appellee showed a realistic danger that the city’s application of the ordinance significantly compromised protected expression, and the Supreme Court did not disturb that conclusion.43 The Supreme Court further observed that the ordinance was “admittedly violated scores of times daily . . . .”44

*99In this case, however, defendant provides no examples of protected expression that the ordinance has or could prohibit, and his characterization of the behavior for which he was cited as merely asking a parking official for his name is inconsistent with a fair reading of the record.45 In particular, there is evidence that defendant drove toward the parking official in his vehicle at an aggressive speed, leapt out of his vehicle, approached the official in an aggressive manner, took pictures of the official with his cell phone, yelled at the official regarding the ticket, and demanded to know the official’s name. In response, and out of concern for what defendant might do next, the official returned to the inside of his truck and summoned the university police for assistance. Although I do not opine on defendant’s as-applied challenge, the record viewed as a whole belies defendant’s claim that he received a citation merely for interrupting a parking official to ask for his name. Defendant has also otherwise failed to show a history of enforcement of the ordinance against protected expression. Finally, unlike in Hill, no one has admitted that the ordinance at issue in this case is violated scores of times daily by persons engaging in protected expression.46 Thus, I do not believe that defendant has dem*100onstrated a realistic danger that MSU Ordinance, § 15.05 will significantly compromise First Amendment freedoms.

An ordinance’s enforcement mechanism may also be relevant to whether the ordinance presents a realistic danger of significantly compromising protected expression, as the Court suggested in Hill. The Houston ordinance prohibited interrupting police officers, the same class of individuals with the discretionary power to arrest individuals under the ordinance. As the Court explained, “[t]he freedom of individuals verbally to oppose or challenge police action without hereby risking arrest is one of the principal characteristics by which we distinguish a free nation from a police state.”47 The Court also stated that it has “repeatedly invalidated laws that provide the police with unfettered discretion to arrest individuals for words or conduct that annoy or offend them.”48 Thus, the Court considered it especially concerning that enforcement of the Houston ordinance was entrusted to the sole objects of its prohibition. This feature of the ordinance presented an “ ‘opportunity for abuse’ ” that the Court had previously admonished *101legislators to avoid49 and made the ordinance “susceptible of regular application to protected expression.”50

In this case, because the persons protected against disruptions are not limited to the police, there are many circumstances, including this case, under which enforcement of the ordinance is carried out by a neutral third party rather than left to the unfettered discretion of the object of the prohibition. Therefore, even if I were to assume that MSU Ordinance, § 15.05 reaches a substantial amount of protected expression, which I do not, it presents a reduced opportunity for abuse and is less susceptible of regular application to protected expression than the Houston ordinance.51

IV CONSIDERATIONS OF THE ACADEMIC ENVIRONMENT

It is apparently of little consequence to the majority that this case concerns an ordinance adopted by an institution of higher education. To the extent that an academic environment is at issue in this ordinance, it is far more likely that speech-related activities (both inside and outside the classroom) will be the object of disruptions than that such activities will be undermined by the prohibition against disruptions. In this *102way, the ordinance as written may actually serve to promote the dissemination of ideas rather than threaten them.

Further, just as picketing outside courthouses52 disruptive rallies within libraries,53 and speech that disrupts the workplace54 can be constitutionally prohibited, a university can implement measures to prevent disruptions of the academic environment.55 Even campus newspapers are not entitled to the same degree of *103free speech as the Lansing State Journal because of the particular mission of the university.56 By striking down MSU Ordinance, § 15.05, the majority is not only compromising the ability of parking officials to safely respond to irate behavior, but it is also preventing MSU from regulating numerous other disruptive activities that interfere with its core academic mission.

Finally, it is useful to consider the campus disruptions that MSU Ordinance, § 15.05 will no longer cover because it has been partially struck down by the majority: (1) a person running onto the field of a stadium during a sporting event, (2) a person blaring music during a lecture, (3) a person interfering with the progress or movement of an individual cleaning or maintaining a university building, (4) a person prevent*104ing the entrance of students into a classroom by physically blocking the classroom door, (5) a person shining a laser pointer during a performance or lecture, (6) a person turning the lights on and off in a classroom during an exam, (7) a person continually making noise in the library, (8) a person calling in a false bomb threat, and (9) a person pulling a fire alarm in the absence of a fire emergency. These are just a few of the countless nonexpressive campus occurrences that might throw into confusion or disorder the normal activity of a protected person. These illustrations highlight the tangible consequences of the majority’s decision.57

V CONCLUSION

For the foregoing reasons, I conclude that Hill provides insufficient grounds for this Court to invalidate MSU Ordinance, § 15.05. At best, Hill supports the conclusion that the ordinance reaches less protected expression and presents less danger of compromising First Amendment freedoms than the Houston ordinance. I also consider it significant that this ordinance *105was adopted by an academic institution. Because Hill provides the sole basis for defendant’s overbreadth challenge, I do not believe that defendant has met his burden in this case. Accordingly, I dissent from the majority opinion and would instead affirm the judgment of the Court of Appeals, which upheld MSU Ordinance, § 15.05 as constitutional on its face and remanded the case to the circuit court for consideration of defendant’s as-applied challenge.
