Jeffrey A. Johnson (“Johnson”) is currently serving three years of supervised release, imposed by the United States District Court for the Northern District of New York (Thomas J. McAvoy, Judge) as part of his sentence for sexual predation against minors. He challenges certain modifications to his conditions of supervised release. 1 Johnson argues that: (i) mandatory polygraph testing to ensure compliance with the terms of his supervised release is not reasonably related to the purposes of sentencing and is a violation of his Fifth Amendment rights against self-incrimination; (ii) a bar on direct or indirect contact with minors is unconstitutionally vague; and (iii) a ban on using any computer with Internet access is an excessive deprivation of liberty.
BACKGROUND
a. Johnson’s Criminal History
Johnson is a convicted sex offender. He is also an Aerospace Engineer and a sophisticated user of computers. Between 1995 and 1997, Johnson used the Internet *275 to conduct sexually-explicit conversations with minors, and to lure several of them to meetings. He had sex with two minors and was arrested while on his way to have sex with a third.
Johnson pleaded guilty and was principally sentenced to 88 months in prison to be followed by three years of supervised release. Conditions governing Johnson’s supervised release were ordered in three waves. At sentencing, the court imposed three conditions: (1) that Johnson participate in a mental health evaluation and/or treatment program; (2) that Johnson not associate with any individual under the age of 18 (except by permission of his probation officer); and (3) that Johnson not possess or use a computer to access any on-line computer service (except by permission of his probation officer).
On July 22, 2004, the Probation Departs ment petitioned for several modifications to Johnson’s conditions of supervised release: (1) mandatory sex-offender treatment using polygraph testing “to obtain information necessary for risk management and treatment”; (2) a prohibition on direct or indirect contact with minors and presence in areas in which minors are likely to congregate (such as schools, child care centers, and playgrounds); and (3) relaxation of the previous total ban on Johnson’s computer use if Johnson participated in the Computer Restriction and Monitoring Program, which would have allowed the Probation Office to install software aimed at monitoring his computer use. Johnson challenged all of these modifications.
b. Polygraph Testing
Johnson objected to polygraph testing on two grounds. First, he argued that, without use and derivative use immunity, he could be deprived of his Fifth Amendment rights against self-incrimination and face the dilemma of confessing his sins or remaining silent (and going to jail for violating a condition of supervised release). Second, Johnson argued that the district court should not impose polygraph testing because such testing is unreliable and not reasonably related to the purposes of sentencing, and therefore cannot be employed in a special condition of supervised release.
The district court agreed with the Probation Department on the benefits of polygraph testing, but partially accommodated Johnson’s Fifth Amendment concern by adding certain safeguards. The court limited the scope of examinations to “information necessary for supervision, case monitoring, and treatment,” and made clear that (though Johnson would be compelled to answer) “if a truthful answer would expose him to a prosecution for a crime different from the one on which he was already convicted,” he would preserve his “right to challenge in a court of law the use of such statements as violations of his Fifth Amendment rights” — or, “[i]n other words, [Johnson] must answer the questions posed to him, but, by answering, he will not be waiving his Fifth Amendment rights with respect to any criminal prosecution unrelated to the conviction for which he is now on supervised release.” Johnson appeals these rulings.
c. Ban on Direct and Indirect Contact with Minors
The second modification sought by the Probation Department was to prohibit “any direct or indirect contact with a person under age 18.” Johnson challenged this proposed modification as both vague and impossible: vague, because it “provides no notice to [him] as to what conduct he is prohibited from engaging in”; impossible, because “the possibilities for making inadvertent ‘indirect’ contact with persons under age 18 are a virtual certainty upon *276 [his] leaving his house and conducting normal day to day business.”
The district court agreed with Johnson that “the word ‘indirect’ casts too broad of a net” and ihodified Johnson’s conditions to require that he “reasonably avoid and/or remove himself from situations in which he has indirect contact with a minor.” The modified conditions also require that “[Johnson] shall not have any direct contact with a person under the age of 18 unless it' is supervised by a person approved of by the probation officer.” The modification also takes into account the indeterminacy of the word “indirect” by decreeing that Johnson “shall not have indirect contact with a person under the age of 18 through another person or through a device (including a telephone, computer, radio, or other means) unless it is supervised by a person approved of by the probation officer.” (emphasis added). Johnson argues that in spite of the district court’s stated objective, the plain language of the modification still allowed for inadvertent violation. The government supports the ban as worded.
d. Modification Banning Use of Computers with Internet Access
Johnson objected to computer monitoring; his objection became moot when this condition was modified a second time. In December 2004 the Probation Department, in response to the comments of treatment officials, requested a further modification of Johnson’s conditions of supervised release. The Government sought to bar Johnson from using any computer with Internet access, until his progress in treatment reduced his risk of recidivism. The district court ordered an evidentiary hearing to explore the tension between Second Circuit precedent guaranteeing minimal Internet access and the perceived necessity of an outright ban in this case.
At the two-day hearing, Johnson’s Probation Officer — Agnes McBride — testified that Johnson was expelled from treatment by the Tompkins County Mental Health Clinic (“Treatment Agency”) for failing to agree to refrain from using the Internet and for otherwise failing to participate fully in his program. Ms. McBride accused Johnson of complying with his treatment program “superficially,” doing what he was specifically asked to do without “acknowledging] that he needs to make any changes in his life-style.” Ms. McBride viewed this generally resistant attitude as a sign that Johnson remained a high risk to re-offend, and that stepped-up limits on Internet access were needed.
Linda Riley, a clinic supervisor with the Treatment Agency, confirmed that an outright ban on Internet access was needed for Johnson’s treatment: “[T]he Internet is an instrument of his offending ... Access to the Internet is a risk situation because he does not have the internal controls ... necessary to not offend.”
Johnson sponsored the testimony of Dr. Richard Maxwell, a clinical psychologist whose clinical practice centered on depression, anxiety disorders, and marital problems, and who devoted only a “small amount” of his practice to sex offenders. Dr. Maxwell opined that access to the Internet would allow Johnson to develop socially and professionally, but conceded that “I don’t ... really know at this point ... whether Mr. Johnson is a pedophile or ... somebody with a sexual addiction,” and added that his risk assessment of Johnson’s Internet use “obviously ... would be wrong” “[i]f he’s a pedophile.”
The district court adopted the proposed modification. In so doing, the court distinguished Second Circuit cases (which had held outright Internet bans to be over-broad) on several grounds: use of the Internet in the commission of Johnson’s pre *277 vious offenses; the severity of Johnson’s offenses; fear that Johnson — a computer expert — could circumvent any lesser restriction; and the treatment necessity for an outright ban.
DISCUSSION
In reviewing conditions of supervised release imposed by a district court, issues of law are reviewed
de novo. United States v. Lifshitz,
I. Polygraph Testing
Federal sentencing policy requires that conditions of supervised release impose no greater restraint than reasonably necessary to promote sentencing goals. We have never considered whether polygraph testing is a condition that satisfies this test, nor have we considered whether such a condition offends the Fifth Amendment right against self-incrimination.
a. Objectives of Sentencing
The district courts may:
impose special conditions of supervised release to the extent that they are ‘reasonably related’ to (i) the nature and circumstances of the offense and the history and characteristics of the defendant, and (ii) the purposes of sentencing, including the need to afford adequate deterrence, to protect the public from further crimes of the defendant, and to provide the defendant with needed training or treatment.
United States v. Germosen,
Other circuits have concluded that polygraph testing may serve salutary purposes in the supervised release context.
See, e.g., United States v. York,
Johnson cites,
inter alia, United States v. Scheffer,
As Johnson points out, polygraph results are inadmissible as evidence. But that does not much bear on the therapeutic value of the tool:
[T]he polygraph test ... is inadmissible in nearly every circumstance at trial. Obviously, however, evidentiary cases do not govern our evaluation of the use of polygraphs in connection with the treatment of an offender. The use of a polygraph test here is not aimed at gathering evidence to inculpate or exculpate [the offender]. Rather, the test is contemplated as a potential treatment tool upon [an offender’s] release from prison
Dotson,
The case for use of polygraph testing is strong here in light of “the nature and circumstances of the offense and the history and characteristics of the defendant.”
Germosen,
b. Fifth Amendment Challenge
Johnson argues that if he commits future offenses, or is asked about past offenses other than the ones for which he was convicted, he will be put to the choice of incriminating himself (by answering polygraph questions truthfully) or violating supervised release (by answering untruthfully, or not at all). The first question is whether this challenge is ripe.
See United States v. Antelope,
At the moment, Johnson has suffered no injury from polygraph testing; but he can be injured because he might end up in jail if he truthfully confesses a new offense during testing, falsely denies it, or invokes the Fifth Amendment to avoid answering. Yet, Johnson may not have committed of *279 fenses in the past other than those for which he was convicted, and he may abstain from criminal activity while on supervised release; even if he does not, Johnson’s probation officer may never ask a question sufficiently probing to justify invocation of the Fifth Amendment, or an incriminating answer may be ignored by prosecutors, or the district court may find no supervised release violation.
Although it does not appear that we have previously considered ripeness in the context of a challenge such as that made by Johnson, several other circuit courts have considered similar challenges, and all have found them ripe for decision, regardless of whether the defendant had yet suffered penal injury. In
Antelope,
Generally, a challenge lacks ripeness if it concerns abstract regulations or if it presents issues that might never arise.
See Motor Vehicle Mfrs. Ass’n v. New York State Dept. of Envtl. Conservation,
Unless the self-incrimination issue raised by a condition of supervised release is deemed ripe when it is imposed, an offender who believes the Fifth Amendment protects his statements must face the threat of prison, either in a new criminal prosecution or in a revocation proceeding. Johnson’s challenge is therefore ripe.
On the merits, though, Johnson fails. Second Circuit precedent allows the revocation of supervised release of an offender who fails to answer questions even if they are self-incriminating. In
Asher-
*280
man v. Meachum,
stayed well within [his] authority ... by conducting a relevant inquiry and then taking appropriate adverse action, not for [the offender’s] invocation of his constitutional rights, but for his failure to answer a relevant inquiry.... [A] prisoner may be terminated from home release status for refusing to divulge to a corrections commissioner information pertinent to the administration of a home release program.
Id. at 983.
Johnson’s dilemma is harsh but it is not of constitutional salience. The only distinction between Askerman and this case is the polygraph. But as Johnson admitted at oral argument, the use of the lie detector has no impact on Fifth Amendment considerations. Askerman therefore applies directly. The polygraph condition at issue here conforms to Ashennan by preserving Johnson’s “right to challenge in a court of law the use of [incriminating] statements as violations of his Fifth Amendment rights.”
II. The Bar on Direct and Indirect Contact
The district court tried to make Johnson “cognizant of the requirement that he reasonably avoid and/or remove himself from situations in which he has indirect contact with a minor.” (emphasis added). This goal was implemented in the following four modifications:
3. You shall not have any direct contact with a person under the age of 18
4. You shall not have indirect contact with a person under the age of 18 through another person or through a device (including a telephone, computer, radio, or other means) ....
5. You shall reasonably avoid and remove yourself from situations in which you have any other form of contact with a minor.
6. You shall not be in any area in which persons under the age of 18 are likely to congregate, such as school grounds, child care centers, or playgrounds
(emphasis added). Johnson challenges the direct and indirect contact conditions of his supervised release as unconstitutionally vague. According to Johnson, “the condition of supervised release is missing language pertaining to ... intent or awareness,” such that “Johnson might innocently or unintentionally have indirect contact with a minor that would violate [a] condition of supervised release.”
The Due Process clause requires that “Conditions of supervised release ... ‘give the person of ordinary intelligence a reasonable opportunity to know what is prohibited, so that he may act accordingly.’ ”
United States v. Baton,
In response to Johnson’s concerns, the district court expanded on the wording sought by the government, and specified that “indirect” contact includes contact through a device (such as a phone) or through an intermediary (such as another person). The court thus refined the term to involve some purposeful initiative. As so modified, even the maximal scope of the contact provisions allows a person of ordinary intelligence to know what is prohibited.
When Johnson protested that the government’s proposed condition might “result in a violation based on unintentional conduct,” the court agreed “that the word ‘indirect’ casts too broad of a net.” The court’s decision expressed the intent to limit the modification to ensuring that Johnson is “cognizant of the requirement that he reasonably avoid and/or remove himself from situations in which he has indirect contact with a minor.”
Generally, supervised release provisions are read to exclude inadvertent violations. In
Arciniega v. Freeman,
the Supreme Court assumed that a term barring “association” with ex-convicts does not cover “incidental contacts.”
Finally, the structure of the supervised release modifications clearly indicates that inadvertent contact with minors does not (without more) result in a violation. In addition to the direct and indirect contact provisions, the district court required Johnson to “reasonably avoid and remove” himself from situations in which he has any contact with a minor. If Johnson’s failure to leave triggers a supervised release violation, it follows that he may avoid a violation by extricating himself from situations in which inadvertent contact with minors occurs. Absent an inadvertent encounter with a minor that is precipitated by some lack of care to avoid it, the modified conditions assure that no violation occurs where incidental contact is followed by immediate removal.
Since the conditions provide clear notice of what conduct they prohibit and do not demand the impossible, Johnson’s vagueness challenge fails.
III. Absolute Internet Ban
The new Internet condition required that Johnson “not use or possess any computer ... with online capabilities at any location until ... cleared to do so” by the district court. Johnson argues that this outright ban contravenes several precedents in which this Court has preserved at least minimal, government-monitored Internet access for persons on supervised release.
a. Sentencing objective relevance
As already discussed, a condition of supervised release must be related to sentencing purposes and must impose no greater restraint on liberty than is reasonably necessary to accomplish sentencing objectives.
United States v. Germosen,
The Internet ban imposed on Johnson serves these sentencing objectives, confronts Johnson with the need to take his treatment seriously, and selves as an external control to predatory Internet be *282 havior, standing in for Johnson’s deficient internal controls. Treatment officials suggest that such external checks often become internalized, promoting healthy behavior in the long term. The question is whether a lesser restraint would do.
b. Minimum Deprivation of Liberty
Several times this Court has vacated absolute bans on Internet access because narrower restraints were equally suited to achieving sentencing goals. The district court distinguished those cases on the ground that nothing less will effectively curb Johnson’s propensities and protect the community. On this record, that ruling is sound.
In the case of an offender who had downloaded and disseminated child pornography through the Internet, an outright ban was held to be more restrictive than needed to serve the sentencing goals of rehabilitation and incapacitation because a combination of monitoring and unannounced inspections would exert the control of an Internet ban while allowing an offender access to the Internet for legitimate purposes.
See United States v. Sofsky,
As shown in the thorough record compiled in the district court, Johnson’s case differs from those cases on two important grounds: the characteristics of the offender and the nature of his past offenses. 2
After a two day evidentiary hearing at which both Johnson and the government called witnesses and presented other evidence, the district court found,
inter alia,
that Johnson was in denial about his risk of re-offending, had not come to terms with what caused him to commit his crimes, had been “less than truthful with his mental heath care providers and with probation,” and had “acted in a secretive manner concerning his sexual activity.” The district court also found credible the testimony of Johnson’s treatment provider that these actions suggested that Johnson was at a high risk for re-offending.
See United States v. Johnson,
No. 97-cr-0206, 98-cr-160,
In addition, as Johnson concedes, he is a sophisticated computer user (and an experienced engineer), and the district court found that a person with his skills likely could circumvent the software needed for monitoring. Johnson’s employer believes that inappropriate Internet abuse at work “would be noticed very rapidly” due to the office’s public culture, and it may be that co-workers would notice if Johnson were accessing and downloading pornographic images (at least during normal business hours), and that Johnson would strongly prefer to keep such images from the sight of others. However, chatting, emailing and messaging can be conducted without tell-tale screen images, and co-workers may be gone after work hours or on weekends. The court did not abuse its discre *283 tion in concluding that casual oversight in the workplace would not control a sex offender who is in need of treatment and who has engineering and computer skills that could be used to defeat monitoring by anyone.
In determining what condition of release is reasonably necessary to protect the community, a court may of course consider the hazard presented by recidivism. In Sofsky, the likeliest consequence if a less restrictive measure should fail would be that the offender would download and distribute child pornography. Serious as those offenses are, the direct harm to children was inflicted previously, when the pornographic images were made, and the lesser harm caused by trafficking can be largely remedied afterward, by destroying copies of the material and returning the offender to prison. In Johnson’s case, the likeliest consequence if a less restrictive measure should fail is that Johnson could use the Internet to locate children and lure them to sexual abuse. The perfectly obvious ground for distinguishing Sofsky from Johnson’s case is that here the failure of lesser measures risks direct harm to children that may be devastating and irremediable.
As the Seventh Circuit observed in
United States v. Holm,
We therefore affirm the imposition of the absolute Internet ban as it has been crafted in this case.
CONCLUSION
We have considered Johnson’s remaining arguments and find each of them to be without merit. For the foregoing reasons, the various orders of the district court modifying conditions of Johnson’s supervised release are affirmed.
Notes
. The pertinent modifications were imposed as part of two orders. The first order was entered on August 19, 2004 and contained the polygraph and indirect contact modifications. The second order was entered on January 5, 2005, and contained the Internet-ban modification.
. We do not hold that an outright ban on Internet use is categorically appropriate for any sex offender whose offense involves use of the Internet. We think that, in light of our recognition that "Internet access ha[s] become virtually indispensable in the modern world of communications and information gathering,"
