Michael T. Ken* pleaded guilty to distribution of child pornography in violation of 18 U.S.C. § 2252A(a)(l) and possession of child pornography in violation of 18 U.S.C. § 2252A(a)(5)(B). The district court 1 sentenced him to 151 months of imprisonment and ten years of supervised release. Kerr appeals challenging the validity of several special conditions of his release as well as the district court’s recommendation to the Bureau of Prisons (BOP) that he participate in sex offender treatment while incarcerated. We affirm.
On October 14, 2004, FBI Innocent Images Task Force Officer James Kite downloaded a pornographic image from Kerr’s computer depicting sexual intercourse between two pre-teen minors. Kerr had set up an image exchange with other computer users. He placed a notice on an Internet Relay Chat (IRC) 2 channel entitled #100% PRETEENGIRLSEXPICS, which offered access to pornographic images of pre-teen girls on a file server 3 on Kerr’s computer. The notice explained IRC users could download an image from Kerr’s file server only if they first uploaded an image onto Kerr’s computer. Pursuant to these instructions, Officer Kite first uploaded a non-pornographic image onto Kerr’s computer and then downloaded the image in question. Due to the content of the image, the FBI obtained and executed a search warrant of Kerr’s home. Subsequent forensic analysis of Kerr’s computer uncovered between forty-five and fifty files containing images of child pornography, some depicting children under the age of twelve and sadomasochistic violence. Although Kerr initially denied he possessed child pornography, he eventually admitted both possession and distribution of the images. He claimed he distributed these images in an attempt to spread a computer virus to the computers of pedophiles. According to Kerr, he initiated this project in October 2004 and received several images from IRC users he intended to delete. He further claimed his “virus project” was ultimately unsuccessful and, as a result, he deleted most of the images uploaded onto his computer as well as the virus files. In response to this claim, the FBI conducted further forensic analysis of Kerr’s computer which failed to corroborate his story.
At sentencing, Kerr did not dispute the charges against him, rather he again claimed he only possessed and distributed the child pornography in order to spread a computer virus. The district court rejected this claim noting “I don’t believe it, and there is no objective evidence to substantiate [Kerr’s] story.” On appeal he concedes the district court rejected his story. *520 At sentencing, he presented the expert report and testimony of psychologist Holli-da Wakefield who concluded he was not a pedophile. She recommended Kerr receive no sex offender treatment while incarcerated or while on supervised release, as such treatment was unnecessary and would be harmful to him. The district court discounted Wakefield’s testimony and report:
I also find there is no way for anyone, including Ms. Wakefield, to predict who will offend as a sex offender. Many of her — all of her conclusions — except for the testing of the IQ and the Minnesota Multiphasic Personality Inventory, all of her conclusions are based on unquestioningly accepting [Kerr’s] statements without any backup. She just took them at face value, and then applied her hunches. I find that she does not have specific expertise in sexual deviance and that many of the opinions she offered are lacking in foundation. I did not find her report helpful.
The district court sentenced Kerr to the low end of the advisory guideline range of 151 to 188 months and imposed a supervised release term of ten years. In its sentencing order, the district court recommended to the BOP that he participate in sex offender treatment while incarcerated. The district court also imposed several conditions of supervised release including certain conditions: 1) requiring him to register with the sex offender registration agency in the state where he resides or works; 2) requiring him to participate in a mental health evaluation and/or treatment program, as directed by his probation officer; and 3) requiring him to obtain permission from the probation office prior to contacting minors or going to places where minors congregate. Kerr did not object to these conditions at sentencing. On appeal, he does not challenge his sentence but rather challenges the district court’s recommendation to the BOP and the above-referenced terms of his supervised release. He also argues the district court improperly delegated to the probation office the decision of whether he should participate in sex offender treatment during supervised release.
Kerr first argues the district court erred in recommending to the BOP that he receive sex offender treatment while incarcerated. He asks the court to vacate the recommendation and remand for resentencing. Pursuant to 28 U.S.C. § 1291, we have jurisdiction over final decisions of district courts. As an initial matter, a district court’s recommendation is not binding on the BOP.
See United States v. Creed,
Kerr next objects to several conditions of his supervised release. “A sentencing judge is afforded wide discretion when im
*521
posing terms of supervised release.”
United States v. Crume,
Kerr argues the district court erred in requiring him to register as a sex offender as a condition of his supervised release. He claims this condition is not warranted as there is no evidence he is actually a sexual predator, Wakefield’s testimony verified he is not a sexual predator, and Iowa law does not require persons convicted of distributing or possessing child pornography to register as sex offenders. He acknowledges the sentencing guidelines list registration as a “mandatory condition” of supervised release for sex offenses,
see
U.S. Sentencing Guidelines (U.S.S.G.) 5D1.3(a)(7) (2005), but argues this provision is merely advisory after
United States v. Booker,
As a threshold matter, Kerr is incorrect when he claims the Iowa Code does not require those convicted of distributing or possessing child pornography to register as sex offenders.
See
Iowa Code §§ 692A.2, 692A. l(5)(m), and 728.12 (mandating sex offender registration of those convicted of promoting or possessing child pornography as these offenses constitute “criminal offense[s] against a minor”). As for his argument there is no evidence he is a sexual predator and there is strong credible evidence contrary to this finding, this argument hinges on Wakefield’s testimony and report. As is clear from the district court’s comments at sentencing, however, it was not persuaded by this evidence. The district court discredited Wakefield’s testimony and found her report was not helpful. A district court is not required to accept an expert’s opinions during sentencing.
Ramos v. Weber,
Kerr next argues the district court erred in imposing three special conditions of supervised release which limit his contact with minors. Special Condition Eight provides he is not to communicate with minors online without prior permission from his probation officer. Special Condition Nine broadens the restriction precluding any contact with a minor without per
*522
mission. Finally Special Condition Ten restricts his access to places where minors congregate without first obtaining permission. He argues these restrictions are unnecessary, are not reasonably related to the goal of rehabilitation, and are not supported by the evidence against him. Again, he relies heavily on the testimony of Wakefield. She testified Kerr is not likely to be a recidivist and is not a danger to children. He does not argue these contact conditions should not be imposed in
any
case involving child pornography, but instead argues they should not be imposed in
his
case. This is so because his offenses should be characterized as computer offenses rather than sex offenses. Kerr primarily relies on two cases in support of his contention. In
United States v. Scott,
The undisputed evidence demonstrates Kerr possessed and distributed child pornography, some depicting the sadistic and violent sexual abuse of pre-teen minors. This court has, in several instances, upheld similar conditions limiting contact with minors in child pornography possession cases, albeit in cases involving defendants with records of sexual abuse of minors.
See United States v. Mark,
*523
Recently, however, in
United States v. Mickelson,
We are persuaded by the reasoning in
Mickelson.
While Kerr does not have a history of abusing minors, his offenses include both the possession and distribution of child pornography. We have found child pornography distribution offenses are more serious than mere possession offenses.
See United States v. Fields,
Finally, Kerr contends the district court erred in imposing a special condition which he claims impermissibly delegates to the probation office the decision of whether to place him in a sex offender treatment program upon his release from prison. Special Condition Four mandates: “The defendant shall participate in a mental health evaluation and/or treatment program, as directed by his probation officer. This may include participation in a sex offender treatment program or any such similar program offered in the defendant’s approved district of residence.”
A sentencing judge may delegate limited authority to non-judicial officials as long as the judge retains and exercises ultimate responsibility.
Mickelson,
Accordingly, the judgment of the district court is affirmed.
