Wisconsin prisoner Joseph Koutnik brought this action under 42 U.S.C. § 1983 after an employee of the prison in which he is incarcerated seized an article of his outgoing mail. Mr. Koutnik claims that the Wisconsin regulation relied upon by the defendants to justify the seizure vio *780 lates the First Amendment on its face and as applied to him; he also claims that the defendants’ actions violated his substantive due process rights. The district court dismissed Mr. Koutnik’s facial challenge and his due process claim, and it granted summary judgment to the defendants on his remaining First Amendment claim. For the reasons set forth in this opinion, we affirm the judgment of the district court.
I
A.
Mr. Koutnik is confined at the Wisconsin Secure Program Facility. In December 2002, he placed in the outgoing mail a letter addressed to Northern Sun Merchandising (“Northern Sun”), a company that sells politically oriented products, including t-shirts, posters and stickers. Northern Sun invites design proposals for its products and pays royalties if an idea is marketed successfully. Mr. Koutnik’s letter encouraged Northern Sun to add communist-themed posters to its product line and also suggested developing a line of small posters targeted at inmates who are prohibited by prison regulations from possessing stickers and large posters. Mr. Koutnik also wrote: “I noticed that prison reform is not as well represented as is needed and am therefore including some of my ideas you should consider using. [L]et me know what you think.” R.10, Ex.D. Several designs were included as attachments. One, taking a page to itself, was a drawing of a swastika textured with the image of cell bars. Above the swastika was the slogan “The Department of Corruptions,” and below it was the slogan “Keeping Kids in Kages” written with enlarged, stylized capital Ks. Id., Ex.F.
Lebbeus Brown, then a lieutenant at the facility, prevented Mr. Koutnik’s letter from being sent. He issued a “Notice of Non-Delivery of Mail,” advising Mr. Kout-nik that the swastika drawing violated Wisconsin Administrative Code DOC § 303.20. In relevant part, that section provides:
Any inmate who participates in any activity with an inmate gang, as defined in [§ ] DOC 303.03(11), or possesses any gang literature, creed, symbols or sym-bolisms is guilty of an offense. An inmate’s possession of gang literature, creed symbols or symbolism is an act which shows that the inmate violates the rule. Institution staff may determine on a case by case basis what constitutes an unsanctioned group activity.
Wis. Admin. Code DOC § 303.20(3). Lieutenant Brown later would explain that, based on his training and experience, he believes the swastika to be “a symbol of Aryan pride and white supremacy, as well as racial hatred.” R.15 at 8. Moreover, in this particular instance, he perceived the capital Ks and the misspelling of “cages” in “Keeping Kids in Kages” as a reference to the Ku Klux Klan. Id. at 9. The Klan is not a sanctioned group at the facility, see Wis. Admin. Code DOC § 309.365(c)(1), and Lieutenant Brown reasoned that Mr. Koutnik “was identifying with and trying to promote the growth of white supremacy groups while merchandizing white supremacy material,” R.15 at 9. To permit such activity, the Lieutenant concluded, would create a security risk by emboldening white-supremacist inmates to spark racial unrest on the assumption that the facility and the Department of Corrections “were associated with and condoned white supremacy activity.” Id. at 10. Lieutenant Brown also decided that Mr. Koutnik’s desire to merchandize his design was also incompatible with the facility’s efforts to rehabilitate him, even if the design never were reintroduced into the prison system.
*781 B.
Mr. Koutnik filed the present action in which he alleged that Lieutenant Brown’s seizure of the outgoing letter violated both his first amendment and substantive due process rights. Mr. Koutnik first submitted that the regulation upon which Lieutenant Brown relied, DOC § 303.20(3), is facially overbroad and that the seizure did not have a legitimate penalogical purpose. The district court dismissed the overbreadth challenge at the initial screening required by 28 U.S.C. § KUSAfa), 1 but allowed Mr. Koutnik’s as-applied challenge — concerning the use of the regulation to seize his outgoing correspondence — to proceed.
Mr. Koutnik further alleged that the seizure of his letter violated his right to substantive due process. However, the district court took the view that this claim was precluded because the Supreme Court has directed that substantive due process claims be analyzed under the specific provision of the Constitution most relevant to the claim, here the First Amendment.
See Albright v. Oliver,
The district court later granted summary judgment in favor of the defendants, analyzing Mr. Koutnik’s remaining first amendment claim under the standard set out in
Procunier v. Martinez,
II 2
A.
On appeal, Mr. Koutnik first argues that the district court erred in dis *782 missing his facial challenge to Wisconsin Administrative Code DOC § 303.20(3) at the screening stage. This section prohibits participating “in any activity with an inmate gang” or “possessing any gang ... symbols”; in turn, DOC § 303.02(11) defines “an inmate gang” as “a group of inmates which is not sanctioned by the warden.” Mr. Koutnik asserts that, at the Wisconsin Secure Program Facility, there are no inmate groups sanctioned by the warden. Therefore, he argues that DOC § 303.20(3) prohibits the possession of symbolism which could be associated with any group. 3
Mr. Koutnik misreads the provision. The operative section of the administrative code does not prohibit inmates from possessing the symbolism of any group, but rather any inmate group not approved by the warden. This distinction is significant because it makes the provision quite narrow; indeed, if strictly read, DOC § 303.20 would not authorize prison administrators to ban the symbolism of white supremacy groups if there were no inmate groups associated with that cause. With this understanding of the regulation in mind, we turn to Mr. Koutnik’s legal arguments.
To launch a successful over-breadth challenge, a plaintiff must show “that a law punishes a ‘substantial’ amount of protected free speech.”
Virginia v. Hicks,
We turn, then, to Mr. Koutnik’s vagueness challenge.
[E]ven if a law does not reach a substantial amount of constitutionally protected conduct, it can be found to be im-permissibly vague if it fails to define the offense with sufficient definiteness that ordinary people can understand what conduct is prohibited and it fails to establish standards to permit enforcement in a nonarbitrary, nondiscriminatory manner.
Fuller by Fuller v. Decatur Pub. Sch. Bd. of Educ. Sch. Dist. 61,
In the present context, we believe a reasonable person would understand the regulation to prohibit the symbols employed here, a swastika and the letters “KKK.” These symbols have been associated with racist and white supremacist groups for over half of a century — groups, not surprisingly, that are not recognized by the warden. Furthermore, the fact that the regulation provides some latitude to prison officials in defining gang symbols does not render it void for vagueness. Indeed, this court has upheld school regulations prohibiting “gang-like activity” against a vagueness challenge.
See Fuller,
B.
Mr. Koutnik’s remaining first amendment claim is that the statute is unconstitutional as applied to his activity. The district court held, and we agree, that censorship of an inmate’s outgoing mail still is scrutinized under the standard espoused in
Martinez,
There are two prongs to the
Martinez
test. “First, the regulation or practice in question must further an important or substantial governmental interest unrelated to the suppression of expression.”
Martinez,
The district court identified the governmental interest at stake in this case as the rehabilitation of Mr. Koutnik and other inmates. There is no question that the rehabilitation of inmates is a legitimate interest of penal institutions. “The more difficult task however, is not in identifying an important governmental interest at stake, rather it is in determining whether the enforcement of [the rule] was no greater an infringement upon [Mr. Koutnik’s] first amendment liberties than [was] nec *785 essary to protect the state’s interest.” Rios v. Lane, 812 F.2d 1032, 1037 (7th Cir.1987). It is on this element of the Martinez test that Mr. Koutnik focuses his challenge to the district court’s judgment. Specifically, Mr. Koutnik claims that the defendants have not established that the mail sent to Northern Sun contained gang symbols or that “the drawing [of] a swastika and referencing the Ku Klux Klan in an outgoing letter threatens a prisoner’s rehabilitation.” Appellant’s Br. at 20. We now address each of these contentions.
With respect to whether Mr. Koutnik’s mail to Northern Sun contained gang-related symbols, we believe that this is an assessment that prison staff is uniquely suited to make. Knowledge of prison gang symbols — how they are used and what they mean — is acquired primarily through interaction with, and observation of, prisoners. Additionally, gang symbolism is not static; symbols change and are added as gangs expand their bases and combine with other groups. Consequently, because the prison staff has daily contact with gang members and because the number and kind of gang symbols do not remain constant, we shall defer to the staffs assessment that Mr. Koutnik’s correspondence to Northern Sun contained gang symbols.
Cf. Beard v. Banks,
— U.S. -, -,
Mr. Koutnik also maintains that his inclusion of a swastika and his veiled reference to the KKK are not related in any way to his rehabilitation. In his brief, he points to the Supreme Court’s statement in
Martinez
that “the weight of professional opinion seems to be that inmate freedom to correspond with outsiders advances rather than retards the goal of rehabilitation.”
Conclusion
For the foregoing reasons, the judgment of the district court is affirmed.
Affirmed
Notes
. Title 28, § 1915A(a) of the United States Code requires district courts to "review, before docketing, if feasible or, in any event, as soon as practicable after docketing, a complaint in a civil action in which a prisoner seeks redress from a governmental entity or officer or employee of a governmental entity.” In conducting this review, district courts must identify cognizable claims and dismiss the complaint, or any portion thereof, that fails to state a claim.
. Mr. Koutnik initially argues that the district court erred in dismissing his substantive due process claim. In his complaint, Mr. Koutnik alleged that "his right to Free Speech, Substantive Due Process and Freedom of Expression were violated by Defendants.” R.2 at 1. His complaint further alleges that the defen *782 dants' acts "violated Koutnik's first and fourteenth amendment rights,” that the harms were "based on an unconstitutionally vague and overbroad prison rule” and that the regulation should be declared "unconstitutionally vague and overbroad in that ... it is used to punish protected activity as noted in this case.” Id. at 4.
As noted above, in evaluating the substantive due process claim, the district court was guided by the Supreme Court's admonition in
Albright v. Oliver,
We believe the district court employed the correct approach. Here, Mr. Koutnik is alleging that the Department of Corrections promulgated a vague and overbroad regulation that was used to punish protected activity; these allegations invoke the protections against government interference with free speech that are guaranteed by the First Amendment. Consequently, it was proper for the district court to evaluate Mr. Koutnik's claims according to a first amendment framework, cf. Eby-Brown Co., LLC v. Wisconsin Dep't of Agric., 295 F.3d 749, 754 (7th Cir.2002) (citing Albright and refusing to analyze complaints of unequal treatment as substantive due process claims, as opposed to equal protection claims), and we address Mr. Kout-nik's overbreadth and vagueness claims below.
. We note that Mr. Koutnik forwarded identical vagueness and overbreadth arguments in a separate action; this court rejected those arguments in an unpublished order.
Koutnik v. Brown,
. In their brief, the defendants urge that we apply the standard set forth in
Turner v. Safley,
Under our decision in Turner v. Safley ... restrictions on prisoners’ communications to other inmates are constitutional if the restrictions are "reasonably related to legitimate penological interests.” In this case, we are asked to decide whether prisoners possess a First Amendment right to provide legal assistance that enhances the protections otherwise available under Turner ....
Shaw, therefore, did not address the right of prisoners to send mail outside the prison the regulation of which is governed by the Martinez standard. Furthermore, as noted above, after the Court handed down Shaw, other courts of appeals have applied the Martinez standard, not the Turner standard, to evaluate the regulation of prisoners’ outgoing mail.
