OPINION
Gеrald J. “Jack” McLamb (“defendant”) appeals from a judgment of the Maricopa County Superior Court affirming his conviction in the City of Phoenix Municipal Court for a violation of Phoenix City Code (“Code”) section 23-21 proscribing the unauthorized wearing of the official insignia of the Phoenix Police Department. We have jurisdiction to determine the facial validity of this ordinance. Ariz.Rev.Stat. Ann. (“A.R.S.”) § 22- *3 375. Because we find that the ordinance is valid, the judgment of the superior court is affirmed.
FACTS AND PROCEDURAL HISTORY
The facts essential to the resolution of this appeal are not disputed. Thе defendant was a City of Phoenix Police Officer from 1976 through 1986 when he retired. At that time, he was given a Phoenix Police Department retired officer’s badge. The defendant also had what he called his “retirement uniform” which, in part, consisted of an official Phoenix Police Department shirt on which were shoulder patches with the official department insignia.
The defendant had long been involved in a number of political activities. For example, he was the publisher of a newsletter named Aid and Abet which was directed to law enforcement officers with thе expressed purpose of “educating them concerning constitutional issues.” In 1993, he helped form an organization called “Police Against the New World Order.” This organization produced a manual, to which he contributed, called Operation Vampire Killer 2000.
On December 12, 1993, the defendant operated a booth at a gun show at the Arizona Veterans Memorial Coliseum in Phoenix. Over the booth hung banners declaring “Police Against the New World Order,” “Police Support Your Right to Bear Arms” and ‘We Will Not Take Your Guns Away.” The defendant distributed his Aid and Abet newsletter and advertised the Operation Vampire Killer 2000 manual. He wore his “retirement uniform” with the official Phоenix Police Department insignia shoulder patches, as well as his police department retired officer’s badge and a whistle used by department motor officers. Visible in the defendant’s booth was a police helmet. The defendant admitted that he wore the uniform to give weight and credibility to his political views. However, he maintained that he never represented himself to be an active police officer or a spokesman for the Phoenix Police Department.
The Phoenix Police Department received a complaint about the defendant’s conduct in handing out political literature in a police officer’s uniform. In response, Officers David Lundberg and Ted Music went to the gun show and saw the defendant in his attire. They advised the defendant that he could not wear the Phoenix Police Officer’s badge nor the official Phoenix Police Department insignia shoulder patches because his unauthorized use of the badge and insignia violated the Phoenix City Code. The defendant refused to remove his shirt or, alternatively, to remove the patches, claiming that he had а First Amendment right to wear his “retirement uniform.” He then was issued two citations, one for impersonating a police officer in violation of Code section 23-20 and one for wearing an official badge or insignia without authorization in violation of Code section 23-21.
The Phoenix Municipal Court dismissed the Code section 23-20 charge on the basis that it was preempted by state legislation. The court also found that the defendant had not violated section 23-21 by wearing his retired officer’s badge because the badge was not an official one. However, it found that the defendant had violated section 23-21 by wearing the shoulder patches with the official Phoenix Police Department insignia.
Following an evidentiary hearing on the defendant’s claim of selective and discriminatory enforcement, the municipal court found that there was no such exclusive enforcement and that the defendant was guilty of violating Code section 23-21. It fined him $79.
The defendant appealed the conviction and sentence to the superior court, which affirmed the municipal court’s judgment.
The defendant timely appealed to this court. He presents the following issues:
1. Whether his prosecution was impermissibly selective and discriminatory;
2. Whether Code section 23-21 is preempted by A.R.S. section 13-2406;
3. Whether Code section 23-21 is unconstitutionally vague;
4. Whether Code section 23-21 is unconstitutional because it violates the First Amendment to the United States Constitution;
*4 5. Whether Code section 23-21 is unconstitutionally overbroad.
DISCUSSION
A. Selective and Discriminatory Prosecution
Our review is limited to the facial validity of Code section 23-21 because this action was instituted in municipal court and appealed to superior court. A.R.S. § 22-375;
State v. Phillips,
B. Preemption
The City of Phoenix, as authorized by the Arizona Constitution, Article 13, Section 2, has adopted a charter permitting it to enact municipal ordinances. As a charter city, Phoenix may exercise “all the powers authorized by its charter, providing those powers are not inconsistent with the Arizona Constitution or the general laws of this state.”
State v. Jacobson,
The defendant аrgues that Code section 23-21 is preempted by A.R.S. section 13-2406, thus invalidating the ordinance. We disagree.
The rule regarding preemption states:
[Bjoth a city and state may legislate on the same subject when that subject is of local concern or when, though the subject is not of local concern, the charter or particular state legislation confers on the city express power to legislate thereon; but where the subject is of statewide concern, and the legislature has appropriated the field by enacting a statute pertaining thereto, that statute governs throughout the state, and local ordinances contrary thereto are invalid.
Phoenix Respirator & Ambulance Service, Inc. v. McWilliams,
Section 13-2406(A) of the Arizona statutes provides:
A person commits [the crime of] impersonating a public servant if such person pretends to be a public servant and engages in any conduct with the intent to induce another to submit to his pretended official authority or to rely upon his pretended official acts.
Section 23-21 of the Code provides:
It shall be unlawful for any person to wear a fireman’s or policeman’s badge or insignia, or the badge or insignia of any public officer or inspector of the City when not properly authorized to weаr such badge or insignia.
The ordinance bars the unauthorized use of a public officer’s insignia on clothing. In contrast, the statute, with no mention of an insignia, prohibits the impersonation of a public servant engaging in “conduct with the intent to induce another to submit” to his faked authority. There is no conflict between Code Section 23-21 and A.R.S. section 13-2406(A).
The question remains whether the statute “has so completely occupied the field that it becomes the sole and exclusive law on the subject, leaving no room for any supplementary or additional local regulation.”
Jacobson,
*5 C. Vagueness
The defendant argues that Code section 23-21 is unconstitutionally vague. He claims that it failed to give him adequate notice of how and when the ordinance would be enforced and under what circumstances the wearing of Phoenix Police Department insignia would be authorized.
When a law is challenged on the basis of vaguеness or overbreadth, the appellate court has the duty of construing a law in such a manner that it will be constitutional.
State v. Tocco,
“A legislative enactment is unconstitutionally vague if it does not give persons of ordinary intelligence a reasonable opportunity to learn what it prohibits and does not provide explicit standards for those who will apply it.”
State v. Takacs,
The Constitution only requires that language convey a sufficiently definite warning as to proscribed conduct when measured by common understanding and practices. That there will be marginal cases in which it is difficult to determine the side of the line on which a particular fact situation falls is no sufficient reason to hold the language too ambiguous to define a criminal offense. [Citation omitted.]
State v. Cota,
The word “insignia” as used in Code section 23-21 has a well-established, common meaning which а person of ordinary intelligence would understand, 1 and the defendant does not challenge this word. Rather, he claims that the word “authorized” as used in the same code section is vague because the ordinance does not specify when a person is permitted to wear the insignia.
The Oxford English Dictionary (1971) defines the word “authorize” as “to give legal force to; to make legally valid; to give formal approval to; to give legal or formal warrant to (a person) to do something; to empower, permit authoritatively.” See also, Webster’s New Universal Unabridged Dictionary (2d ed.). Its meaning is clear. 2 The fact that the defendant now contends that he did not know prior to being told by Officer Music that he was not authorized to wear the patches with the official Phoenix Police Department insignia does not render the word “authorize” unconstitutionally vague. Rather, the defendant understood the word but allegedly did not know that to wear the insignia was not permitted.
The defendant also claims that the word “authorize” is vague because it gives law enforcement officers discretion whether to enforce Code section 23-21. He illustrates his point by claiming that the spouses and children of Phoenix Police officers wear hats and shirts with the department badges and insignia at picnics or outings without allowance to do so but that they are not prosecuted. He concludes that this demonstrates *6 that the ordinance is vague because the city can arbitrarily enforce it.
As a preliminary issue, there is the question of the defendant’s standing to make this argument. A statute “must of necessity be examined in the light of the conduct with which a defendant is charged.”
Nat’l Dairy Products,
A defendant whose conduct is clearly proscribed by the core of the statute has no standing to attack the statute. “One to whose conduct a statute clearly applies may not successfully challenge it for vagueness.” Parker v. Levy,417 U.S. 733 , 756 [94 S.Ct. 2547 , 2562,41 L.Ed.2d 439 ] (1974). See also Broadrick v. Oklahoma,413 U.S. 601 , 610 [93 S.Ct. 2908 , 2914-15,37 L.Ed.2d 830 ] (1973).
Tocco,
Proceeding nonetheless to address the defendant’s argument, the ordinance sufficiently defines the behavior prohibited: wearing the insignia of any city officer when not properly authorized to wear such insignia. The code section does not apply to a replica, facsimile or other likeness of an insignia. Thus, interpretation of the ordinance is not dependent on the judgment of police officers. To the contrary, the ordinance “gives fair and objective guidelines to both potential offenders and law enforcement personnel” exactly what behavior is prohibited.
Phillips,
When the language is clear, the statute is not rendered unconstitutionally vague because there is a theoretical potential for arbitrary enforcement or the exercise of discretion by a law enforcement officer or prosecutor, or even if the conduct is prevalent and ignored.
Matter of Pima County Juvenile App. No. 74802-2,
D. Violation of First Amendment
The defendant contends that the ordinance on its face violates his First Amendment right of free speech.
3
In support of his position, he relies on
Schacht v. United States,
Our previous cases would seem to make it clear that 18 U.S.C. § 702, making it an offense to wear our military uniforms without authority is, standing alone, a valid statute on its face. But the general prohibition of 18 U.S.C. § 702 cannot always stаnd alone in view of 10 U.S.C. § 772 which authorizes the wearing of military uniforms under certain conditions and circumstances including the circumstance of an actor portraying a member of the armed serves in a “theatrical production.”
Id.
at 61,
It is for that reason, though, that
Schacht
is distinguishable from this case. In
Schacht,
the statute contained a content-based qualification on political speech. Such restrictions are subject to the most exacting scrutiny.
See Boos v. Barry,
The defendant argues that to wear the insignia was a form of expressive speech integral to the spoken presentation of his political views. He relies on
Texas v. Johnson,
In
Johnson,
the defendant was convicted of burning a United States flag contrary to a Texas statute making flag-desecration a crime. In reversing the conviction, the Court stated that, although the First Amendment encompasses both speech and expressive conduct, “[t]he government generally has a freer hand in restricting expressive cоnduct than it has in restricting the written or spoken word.”
Id.
at 406,
Wearing an official Phoenix Police Department insignia in the context in which the defendant was wearing it was expressive conduct. The defendant conceded that he wore the insignia in order to convey a message that he was a former Phoenix Police officer advocating certain political ideas. 5 He also admitted that the insignia was intended to imbue his political beliefs with an aura of importance.
Since the ordinance is not related to the suppression of free expression, the less-stringent standard of O’Brien applies. A four-part test is used to determine when a governmental interest sufficiently justifies the regulation of expressive conduct:
... if it is within the constitutional power of the Government; if it furthers an important or substantial governmental interest; if the governmental 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.
By its terms, Code section 23-21 neither attempts to regulate or restrict the content of the defendant’s expression, nor is it “directed at the communiсative aspect of [the defendant’s] conduct.”
Bird,
The City of Phoenix has a legitimate governmental interest in regulating the use of its official insignia. The police insignia has a “communicative force all its own.”
Thomas v. Whalen,
Such governmental interest has been discussed in analogous cases dealing with statutes or regulations restricting the political and speech activities of government employees. The United States Supreme Court in
United States Civil Service Commission v. National Ass’n of Letter Carriers,
In
Thomas v. Whalen,
In
Paulos v. Breier,
The City of Phoenix has a legitimate governmental interest in restricting the use of its official insignia when the use serves to advance personal political views of the wearer. The city’s tenable interest оutweighs the individual’s interest in advocating those views while wearing such an insignia. As in
O’Brien,
the governmental interest is important and substantial, and the interest is unrelated to the regulation of free expression.
E. Overbreadth
As a related issue, the defendant argues that the statute is overbroad because it prohibits wearing official insignia without authorization under all circumstances, including at home, at social events, in photographs, dramatic presentations, video productions or satirical presentations, or during political protests. He argues that wearing the insignia in these situations is either harmless or directly infringes upon First Amendment rights of expression.
“An overbroad statute is one designed to burden or punish activities which are not constitutionally protected, but ... includes within its scope activities which are protected by the First Amendment.”
State v. Baldwin,
This exception to the ordinary .rule of standing has been carved out in the First Amendment area because the very existence of an overbroad statute may have a chilling effect on persons not before the court.
Broadrick v. Oklahoma,
“[T]he mere fact that one can conceive of some impermissible applications of a statute is not sufficient to render it susceptible to an overbreadth challenge.”
Members of City Council v. Taxpayers for Vincent,
If the Court believes that the statute is so sweeping that it would deter persons from engaging in protected speech, or that the *10 statute may be used on an arbitrary basis against political dissenters, the Court will strike the law as overbroad. If the Court believes that there is little chance that the statute will deter constitutionally prоtected speech, or will be used in a selective manner to punish dissenters, it will uphold the law and allow it to be applied on a “case-by-case” basis.
Ronald D. Rotunda & John E. Nowak, 4
Treatise on Constitutional Law: Substance and Procedure 2nd,
§ 20.8, p. 32 (1992). Thus, -to prevail on an overbreadth claim, “[tjhere must be a realistic danger that the statute will
significantly
jeopardize recognized first amendment protections of individuals not before the court.”
Steiger,
The defendant relies on
Houston v. Hill,
Cоde section 23-21 is not substantially overbroad. The core of the ordinance regulates the wearing of official insignia and is directed at activities in which wearing such insignia compromises the appearance of neutrality and impartiality of the police, fire or other city department. The ordinance is not “a censorial statute, directed at particular groups or viewpoints.”
Broadrick,
CONCLUSION
For the reasons discussed above, we hold that Phoenix City Code section 23-21 is facially valid. We therefore affirm the judgment of the superior court and thereby affirm the defendant’s conviction and sentence.

Notes
. The Oxford English Dictionary (1971) defines insignia as "distinguishing marks of office or honour.” See also, Webster’s New International Dictionary (2d ed.).
. The word "authorize” or its variants is found in many criminal statutes. See e.g, A.R.S. § 13-1504(2) (unlawful to enter and look into residential structure without lawful “authority”); § 13-1803 (unlawful use of means of transportation is temporary "unauthorized” control over another’s means of trаnsportation); § 13-2104 (forgery of credit card is alteration of credit card without the express "authorization” of the issuer); § 13-2316(B) (computer fraud includes altering or destroying any computer without "authorization”).
. The First Amendment to the United States Constitution provides, in part, that there “shall” be "no law ... abridging the freedom of speech.” While the defendant also refers to Article 2, section 6, of the Arizona Constitution (the state counterpart to the First Amendment), because he only relies on cases interpreting the First Amendment, we do not separately discuss the Arizona Constitution.
.
See e.g., United States v. Eichman,
. The defendant, had he been still employed by the Phoenix Police Department, nonetheless would have been prohibited from wearing his uniform at the gun show to promote his political beliefs. "[N]o court has recognized a right to exploit one’s rank in public employment solely for the purpose of enhancing credibility for personal or political gain — in effect, to use the fact of public employment as a 'soap box’ from which the employee can advocate a political position on an issue of public debate.”
