A jury convicted Bruce W. Betcher of twenty-four counts of Production of Child Pornography under 18 U.S.C. §§ 2251(a) and (b), one count of Receipt of Child Pornography under 18 U.S.C. § 2252(a)(2), and one count of Possession of Child Pornography under 18 U.S.C. § 2252(a)(4)(B). On appeal, Betcher argues: (1) 18 U.S.C. § 2251 is unconstitutional due to an insufficient link with interstate commerce; (2) the district court 1 erred by admitting evidence not charged in the indictment because it was cumulative and the probative value was substantially outweighed by unfair prejudice; (3) the testimony of the government’s child abuse expert was irrelevant and prejudicial and the district court abused its discretion by admitting it; and *823 (4) the district court abused its discretion when sentencing him because it failed to properly weigh the 18 U.S.C. § 3553(a) factors. Having jurisdiction under 28 U.S.C. § 1291, we affirm.
I
In 1997, Betcher and his wife obtained custody of their three young grandchildren: two girls, born in 1993 and 1995, and one boy, born in 1996. The children called Betcher “Dad.” In 2004, Betcher took numerous pornographic and erotic pictures of his two young granddaughters and their three girlfriends. At the time the pictures were taken, the girls ranged in age from eight to eleven years old.
Betcher was apprehended after law enforcement found the pictures on a laptop computer in Georgia and subsequently discovered Betcher was the photographer and had transmitted the photos over the internet to the person in Georgia. Further investigation revealed Betcher had additional images of child pornography on his personal computer, including ninety-six pictures and sixteen videos. In his interview with Burnsville Police Department Detective Steve Adrian, Betcher admitted to having a preference for child pornography of prepubescent girls and to receiving and possessing child pornography on his personal computer. He denied having produced any such pictures. Investigators determined it was Betcher’s digital Olympus camera, which was manufactured in Indonesia, which recorded the pornographic pictures.
At trial, Betcher’s defense was the young girls—not he—had taken the photographs of each other. Each of the five girls testified Betcher took the photographs. Betcher’s best friend testified to Betcher admitting to him he took the pictures of the young girls. The jury found him guilty on all counts.
Before sentencing, Betcher submitted a position paper arguing against a life sentence, contending it would be unreasonable because of his allegedly low risk of reoffending and because the Sentencing Commission erred when it crafted the sentencing guidelines for child pornography offenses. After a lengthy sentencing hearing, the district court rejected Betcher’s arguments, calculated the appropriate guidelines range, considered the 18 U.S.C. § 3553(a) factors and concluded a life sentence was reasonable. Because statutory máximums prevented the court from imposing a sentence of life, the court sentenced Betcher to consecutive terms of imprisonment for the statutory maximum term on all counts of conviction, for a total of 9000 months or 750 years. 2
II
Betcher challenges the constitutionality of the statute under which he was convicted for production of child pornography, raises two evidentiary issues, and attacks the reasonableness of his sentence.
A
Betcher argues 18 U.S.C. § 2251 is unconstitutional and, therefore, the district court should have dismissed the production of child pornography charges (Counts 1-24) for lack of federal jurisdiction. We review a challenge to the constitutionality of a federal statute de novo.
United States v. Crawford,
Betcher argues the mere transportation across state or international lines of cameras used in the manufacture of child pornography does not constitute an impact upon interstate commerce sufficient to form a jurisdictional basis upon which Congress could validly prohibit the charged conduct under its Commerce Clause powers. More than one panel of this Court has already rejected this precise constitutional attack.
United States v. Mugan,
B
Betcher contends the district court abused its discretion under Federal Rule of Evidence 403 when it admitted as evidence an additional twenty-six photographs and a video, none of which were charged as production counts in the indictment. Betcher argues the probative value of such evidence was low and was outweighed by the danger of unfair prejudice. We review a district court’s evidentiary rulings for clear abuse of discretion.
United States v. Cannon,
*825
Federal Rule of Evidence 403 provides relevant evidence “may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice.” Fed.R.Evid. 403. “Rule 403 does not offer protection against evidence that is merely prejudicial in the sense of being detrimental to a party’s case. The rule protects against evidence that is
unfairly
prejudicial.”
United States v. McCourt,
The challenged evidence is probative to undermine Betcher’s defense that the girls took the pictures of themselves and distributed them over the internet. The video depicts Betcher and one of his granddaughters sitting at separate computers. Betcher adjusts a web camera to focus on the girl, who is dressed in a long t-shirt and underwear. Betcher reaches toward her inner thigh, at which time she pushes his hand away and says, “Quit.” He responds, “I was videotaping,” and adds, “We’ll try to send it shortly.” This video is relevant to show Betcher was in control of production and distribution, yet does not itself contain pornography or any representation of sexual assault such as would improperly inflame the jury.
The twenty-six uncharged photographs are part of a series of seventy-eight photographs taken of the same five children, on the same fifteen dates, with the same model of camera, in the same home, and transmitted to the same computer in Georgia. From this series, twenty-nine photographs constituting child pornography were charged in the indictment. When viewed together with the charged photographs, the uncharged photographs corroborate the victims’ testimony that Betcher manufactured the pornographic pictures in his home. Some of the uncharged photographs show all five girls together, which indicates someone other than one of the girls took the photographs. In addition, contextual clues in the uncharged photographs—such as the type of underwear worn—assisted in identifying the victims in some charged photos, where the girls’ faces are not visible. As with the video, the uncharged photographs do not contain graphic depictions of child pornography such as would improperly inflame the jury.
We find no danger of unfair prejudice in either the video or the uncharged photographs.
Cf. United States v. Becht,
C
Betcher next contends the district court erred under Federal Rules of Evidence 401 and 403 when it admitted the testimony of Dr. Carolyn Levitt, an expert in child abuse offered by the prosecution. We review a trial court’s decision to allow
*826
expert testimony for an abuse of discretion.
United States v. Kirkie,
Evidence is not admissible if it is not relevant. Fed.R.Evid. 402. Relevant evidence is that “having any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable.” Fed.R.Evid. 401. Dr. Levitt testified on three topics, which Betcher argues were irrelevant: (1) age appropriate sexual behavior, (2) delayed disclosure, and (3) sexual abuse. In addition to being irrelevant because he claims he “was not charged with any crime related to child abuse,” Betcher argues the topic of sexual abuse should also have been excluded because it was unfairly prejudicial, particularly Dr. Levitt’s testimony that child pornography is a form of child abuse. 6 See Fed R. Evid. 403.
Federal Rule of Evidence 702 permits the district court to admit the testimony of a witness whose knowledge, skill, training, experience, or education will assist a trier of fact in understanding the evidence or determining a fact in issue.
Kirkie,
The paramount question for the jury was who produced the pornographic photographs of the young girls. Betcher’s defense was that the girls themselves took the photographs and he argued there were inconsistencies in their accounts regarding who produced them. Dr. Levitt’s testimony was relevant because it educated the jury on issues necessary to their determination of who manufactured the photographs. With regard to her testimony regarding child pornography being a form of child abuse, the comment was used to explain the relevance of her expertise in the area of child sexual abuse. By characterizing child pornography as a form of child abuse, Dr. Levitt was able to show the jury how observations from her work with sexually abused children applied also to Betcher’s victims. Defense counsel did not object at trial to the statement, and the district court did not commit plain error in not striking it sua sponte.
D
Betcher challenges his sentence, arguing it is unreasonable. We review the reasonableness of a sentence for abuse of discretion.
United States v. Bonahoom,
Betcher concedes the district court properly calculated his advisory sentencing range under the U.S. Sentencing Guidelines. He also concedes the court addressed every issue raised in his position paper. In essence, Betcher argues the district court abused its discretion because it rejected his arguments for a sentence of imprisonment for a term less than life.
The district court properly calculated an offense level of 52, which it acknowledged is higher than the maximum level of 43 the guidelines contemplate. With no criminal history points and a maximum offense level, the advisory sentence is life imprisonment. Betcher argued to the district court, and again to this Court on appeal, he deserved a sentence less than life because of low risk of recidivism and because he did not physically harm the children. He also alleged the sentencing range for his offenses was overstated when viewed in the context of the policy goals of the Sentencing Commission; he contends the district court should have imposed a lower sentence to counterbalance this incongruity. 7
After a careful review of the sentencing transcript, we are satisfied the district court “considered the parties’ arguments and ha[d] a reasoned basis for exercising his own legal decisionmaking authority.”
Rita,
We are mindful that a sentence should be sufficient, but not greater than necessary, to accomplish the goals of sentencing. Betcher’s sentence — for practical purposes — is a life sentence, and that is *828 how we view it. The district court emphasized incapacitation among its various sentencing goals and stressed the importance of a life sentence in achieving that result. The absurdity of a 750 year sentence, or even a 10,000 year sentence, should not detract from the gravity of Betcher’s crimes.
Ill
Because of the foregoing, we affirm Betcher’s conviction and his sentence.
Notes
. The Honorable James M. Rosenbaum, Chief Judge, United States District Court for the District of Minnesota.
. For a first time offender, the statutory maximum imprisonment is thirty years for each count of production of child pornography, 18 U.S.C. § 2251(e), twenty years for each count of receipt of child pornography, 18 U.S.C. § 2252(b)(1), and ten years for each count of possession of child pornography, 18 U.S.C. § 2252(b)(2).
. The
Mugan
judgment was vacated because of
United States v. Booker,
.
United States v. Morrison,
. United States v. Lopez,
. In fact, Betcher was charged with a crime related to child abuse; he was charged with manufacturing child pornography using children under the age of twelve years.
See United States v. Bentley,
. Specifically, Betcher's contention with regard to his sentencing range is that Sentencing Commission policy statements indicate the guidelines are fashioned so a first time offender committing an ordinary offense will face a sentencing range beginning with the statutory minimum. In the case of average child pornography offenses, the sentencing range starts much higher than the statutory minimum.
