Devin C. Wilson was convicted on one count of transporting a minor across state lines for prostitution in violation of 18 U.S.C. § 2423(a), two counts of producing child pornography in violation of 18 U.S.C. § 2251(a), and one count of being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g). The district court 1 sentenced him to a total term of 440 months imprisonment. He appeals on various grounds. First, he challenges the denial of his motion to suppress arguing that evidence was improperly seized. Second, he contends that the district court abused its discretion by not instructing the jury that (1) the government was required to prove scienter as to the victim’s age and (2) he was entitled to present a reasonable mistake-of-age defense. In addition, he argues that the indictment was procured through perjured testimony, that problems during voir dire should have resulted in a mistrial, and that the evidence was insufficient to support his conviction. We affirm.
I.
On the evening of September 2, 2006, members of the Caruthersville Police Department received a 911 emergency dispatch to 801 West Eighth Street in Caruthersville, Missouri to investigate a possible kidnapping. When the officers arrived at the residence, a 16-year old female (“the Victim”) was standing outside and got into the officers’ police car. She told the officers that she had been kidnapped in Oklahoma City, Oklahoma. While the Victim was in the police car, *1063 Wilson drove up in his vehicle and the Victim told the officers that he was the person who had kidnapped her. She said that Wilson had forced her to work as a prostitute and exotic dancer and that he had ecstasy pills and crack cocaine in the house. She also said that her bags and clothing were still in the house. Based on this information, the officers arrested Wilson.
One of the arresting officers, Assistant Chief Tony Jones (“Officer Jones”), then went to the prosecuting attorney’s office to prepare an application and affidavit for a warrant to search Wilson’s residence and vehicle. Officer Jones also directed Officer Tina Cook (“Officer Cook”) to interview the Victim. During this interview, the Victim told Officer Cook that Wilson had videotaped her engaging in various sexual acts using a video camera and his cellular phone. The Victim told Officer Cook that Wilson kept the video camera on the floor of the front room of his residence. She also told Officer Cook that Wilson kept drugs and a handgun in a closet on the first floor.
While Officer Cook was interviewing the Victim, Officer Jones was at the prosecuting attorney’s office working on the warrant application. After the application and affidavit were typed, but before they were sworn to by Officer Jones, Officer Cook called prosecuting attorney Mike Hazel and informed him of what the Victim had said during her interview. Hazel added this information in handwriting to the warrant application.
Based on this additional information, Officer Jones obtained a warrant to search Wilson’s residence and vehicle for controlled substances and the Victim’s personal belongings. Immediately prior to executing the warrant, Officer Cook briefed the other officers about her interview with the Victim. During the search, Officer Cook found a video camera on the floor of Wilson’s front room, precisely where the Victim said it would be. Officer Cook removed the video tape and left the camera at Wilson’s residence. Another officer seized a handgun found in a downstairs closet. While searching Wilson’s Cadillac, Officer Jones found a cellular phone with a built-in camera. Although there is some ambiguity in the record about what happened next, Officer Jones eventually opened the phone and observed pornographic photographs stored on it.
At this point, the facts take an odd turn. Officer Jones had fathered two children with a woman named Jennifer Selvege. At the time of the search, Selvege was romantically involved with Wilson, apparently to Officer Jones’s disapproval. Officer Jones had previously asked Selvege not to allow their children to be around Wilson. After finding the phone in Wilson’s vehicle, Officer Jones called Selvege to tell her about the photographs and reiterate his request that she not permit their children to be around Wilson. At the suppression hearing, Selvege testified that, when she was at the Caruthersville police station on a date sometime after the execution of the search warrant, Officer Jones showed her the images stored on the phone. Officer Jones denied that he ever showed Selvege the phone.
Several months after the execution of the search warrant, Federal Bureau of Investigation Agent Herbert Stapleton (“Agent Stapleton”) went to Wilson’s residence to execute a federal arrest warrant for the crime of being a felon in possession of a firearm. Agent Stapleton was aware of the Victim’s child pornography allegations against Wilson. While executing the arrest, he recognized the video camera from photographs he had seen of the prior search. Because of his belief that the camera might be relevant to the child pornography accusations, Agent Stapleton *1064 seized the video camera. Federal agents later sought and obtained a search warrant to search the data stored on the cellular phone and videotape.
Wilson was subsequently indicted on several charges: one count of transporting a minor across state lines for criminal sexual activity in violation of 18 U.S.C. § 2423(a), two counts of producing child pornography in violation of 18 U.S.C. § 2251(a), one count of being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g), and two counts of possessing child pornography in violation of 18 U.S.C. § 2252A(a)(5)(B). Wilson did not challenge the indictment before the district court. He now alleges for the first time that his indictment was procured through the Victim’s perjured testimony.
Wilson filed a motion to suppress the videotape, video camera, cellular phone, and firearm on the theory that the seizure of these items was unlawful because they were not listed with particularity in the search warrant. The district court denied the motion to suppress, explaining that all of these items were in “plain view” and therefore a warrant was not required for their seizure. Wilson now contends that the criminal character of these items was not “immediately apparent” as required by the plain view doctrine.
See, e.g., United States v. Khabeer,
During the pre-trial conference, the government moved to dismiss the possession of child pornography charges. As the government acknowledges, this was done to relieve the prosecution of the need to prove that Wilson knew that the Victim was a minor. 2 The district court granted the motion and dismissed the possession of child pornography charges. The government also sought an order prohibiting Wilson from presenting to the jury any evidence suggesting that he mistakenly believed the Victim to be 18 or older. The district court granted this request as well and approved the government’s proposed jury instruction, which omitted any reference to scienter or a reasonable-mistake-of-age defense.
During voir dire, Wilson moved for a mistrial based on his allegation that the jury pool was biased against him. One of the prospective jurors had related a story about her daughter who had been kidnapped and forced into prostitution. Wilson claims that several jurors were crying in response to this story, and that this display of emotion compromised the jury’s objectivity. The district court denied the request for a mistrial. Finally, at the close of the government’s evidence, Wilson requested a judgment of acquittal arguing that the evidence was legally insufficient to support a conviction. The district court denied his request.
II.
Wilson seeks suppression of the videotape, camera, and cellular phone on the grounds that they were not lawfully seized under the “plain view” exception to the warrant requirement. “The plain view doctrine allows a police officer to seize evidence without a warrant when (1) the officer did not violate the Fourth Amendment in arriving at the place from which the evidence could be plainly viewed, (2) the object’s incriminating character is im
*1065
mediately apparent, and (3) the officer has a lawful right of access to the object itself.”
United States v. Abumayyaleh,
Wilson limits his appeal to whether the incriminating character of the seized items was immediately apparent. “Evidence is immediately apparent if there is probable cause to associate the property [seized] with criminal activity.”
United States v. Armstrong,
Relying solely on
Arizona v. Hicks,
The Victim informed Officer Cook that Wilson had used his cellular phone and a video camera to record her engaging in underage sexual activity. When Officer Cook discovered the video camera lying in the same location the' Victim had described, she removed the tape. Furthermore, Officer Jones knew the details of Officer Cook’s interview with the Victim before he seized the cellular phone. Finally, Agent Stapleton was familiar with the Victim’s allegations and recognized the .video camera from pictures of the earlier search when he seized the camera during Wilson’s subsequent arrest on federal gun charges. Due to this information, probable cause existed, and the incriminating nature of each of the items was immediately apparent. Thus, unlike the stereo equipment in Arizona v. Hicks, the tape, video camera, and phone fall under the plain view exception, and the seizure of these items was proper.
In addition to his plain view challenge, Wilson also argues that the cellular phone was inadmissible based on gaps in its chain of custody. During the pre-trial suppression hearing, Jennifer Selvege testified that Officer Jones had shown her the images on the phone at a date sometime after the initial search and seizure, an allegation that Officer Jones denied. The officer in charge of logging and storing evidence at the Caruthersville Police Department, Frank Cervantes, testified at trial that he did not receive the cellular phone into storage until September 11, 2006, nine days after the search on September 2. Another officer, Sergeant Michael Coleman, testified that he had stored the phone in his desk drawer during the nine day interim.
*1066
“We review a district court’s decision to admit evidence over an objection for an abuse of discretion.”
United States v. Cannon,
III.
Wilson challenges the jury instructions on various grounds. First, he argues that his due process rights were violated because the jury was not instructed that the government must prove he knew the Victim’s age. Second, he contends that the First Amendment requires that he be permitted to argue to the jury that he was reasonably mistaken as to the Victim’s age. District courts have “broad discretion in formulating jury instructions.”
United States v. Farish,
With regard to his first argument, Wilson acknowledges that section 2251(a) contains no scienter requirement.
3
See, e.g., X-Citement Video,
In a somewhat different version of this challenge, Wilson also alleges that his due process rights were violated because the district court refused to submit to the jury Eighth Circuit Model Jury Instruction number 6.18.2422B, which instructs that the defendant must believe the victim to be underage for charges of enticing a minor to engage in sexual activity
*1067
under 18 U.S.C. § 2422(b). There are two insurmountable problems with this claim. First, model jury instructions are just that, models. They are not mandatory,
United States v. Evans,
Wilson’s more colorable claim is that not allowing a reasonable-mistake-of-age defense to charges under section 2251(a) makes the statute overbroad, thereby chilling protected speech in violation of the First Amendment. “[S]ection 2251(a) ... does not, on its face, make reasonable mistake of age an affirmative defense.”
United States v. United States Dist. Ct.,
Although the First Amendment protects non-obscene adult pornography, sexually explicit materials involving persons under the age of 18 enjoy no constitutional protection.
See New York v. Ferber,
However,

distinguished between producers and those who distribute or possess child pornography.
Id.
at 76 n. 5,
We have not had occasion to address this issue in the context of section 2251(a). Other circuits have split as to whether the First Amendment requires reading a reasonable-mistake-of-age defense into the statute.
Compare United States Dist. Ct.,
In
Gilmour,
the defendant sought habeas review of his state court conviction for producing child pornography in violation of section 728.12(1) on the grounds that the First Amendment required that he be permitted to argue to the jury that he was reasonably mistaken as to the victim’s age. We rejected this argument. We explained that, as the Supreme Court noted in
XCitement Video,
the background assumption of
mens rea
is inappropriate for some strict liability sex crimes, such as statutory rape.
Gilmour,
As in
Gilmour,
“we must weigh the statute’s chilling effect against its ‘plainly legitimate sweep.’ ”
IV.
Wilson alleges that the district court abused its discretion in refusing to declare a mistrial based on his claim that four members of the jury pool were crying during voir dire in response to another prospective juror’s emotional story about her daughter who had been a victim of forced prostitution. The juror who related the story, as well as the four who Wilson claims were crying, were struck from the jury panel. All remaining jurors stated that they were able to remain impartial and objective.
“The Sixth Amendment right to jury trial ‘guarantees to the criminally accused a fair trial by a panel of impartial, indifferent jurors.’ ”
United States v. Lussier,
V.
Wilson challenges his indictment based on an allegation that the prosecution committed misconduct by knowingly presenting the Victim’s false testimony to the grand jury. “[G]rand jury proceedings are afforded a strong presumption of regularity, and a defendant seeking to overcome that presumption faces a heavy burden.”
United States v. Hintzman,
806
*1070
F.2d 840, 843 (8th Cir.1986). “The remedy of dismissal for an indictment due to grand jury abuse is appropriate only upon a showing of actual prejudice to the accused.”
United States v. Kouba,
Wilson claims that the Victim told the grand jury that he kidnapped her from Oklahoma, whereas she now acknowledges that she left with him willingly. According to the government, she never alleged to the grand jury that she had been kidnapped. The government argues that the Victim only mentioned the kidnapping in her testimony concerning what she told the police when they arrived at Wilson’s residence.
Regardless of which version is accurate, Wilson’s challenge to the indictment is without merit because “[e]ven assuming ... that there were errors in the charging decision that may have followed from the conduct of the prosecution ..., the petit jury’s guilty verdict rendered those errors harmless.”
Kouba,
VI.
Finally, Wilson charges that the evidence was insufficient to support his conviction on the grounds that the Victim perjured herself before the grand jury and that this undermines the evidentiary basis for the petit jury’s verdict. He also charges that Officer Jones, being motivated by a personal “vendetta” against the defendant, removed the cellular phone from the evidence locker and tampered with it. “[O]ur review of the evidence the Government presented at trial is highly deferential.”
United States v. Kirk,
Regarding the Victim’s grand jury testimony, we are at a loss as to how allegations of perjury before .the grand jury, meritorious or otherwise,, could affect the sufficiency of evidence offered at trial. The Victim testified at trial that Wilson did not kidnap her and- that she left Oklahoma willingly in the expectation that he would employ her as a prostitute in Missouri. Wilson does not challenge this testimony. Thus, his allegations of perjured testimony before the grand jury do not support his insufficiency claim because the conviction by the petit jury was based on testimony the veracity of which is not in dispute. This testimony was sufficient to support conviction on the charge of transportation of a minor to engage in criminal sexual activity under 18 U.S.C. § 2423(a).
We have already discussed Wilson’s failure to show the inadmissibility of the cellular phone due to gaps in its chain of custody. In any event, the data files stored on his phone were not the only evidence that he produced images of a minor engaged in sexually explicit conduct. The video tape, especially when combined with witness testimony, contained ample evidence to support the guilty verdict on two counts of producing child pornography in violation of 18 U.S.C. § 2251(a). The *1071 images stored on his cellular phone only iced the cake of his conviction.
Regarding his conviction for being a felon in possession of a firearm, Wilson stipulated that he had been previously convicted of a felony. He does not challenge the seizure of the firearm from his residence. Witnesses testified that the firearm belonged to Wilson. This was sufficient to support a conviction under 18 U.S.C. § 922(g).
VII.
Accordingly, the judgment is affirmed.
Notes
. The Honorable Henry Edward Autrey, United States District Judge for the Eastern District of Missouri.
. Scienter is an element of the crime of possessing, but not producing, child pornography.
Compare
18 U.S.C. § 2252A(a)(5)(B) (possession), with 18 U.S.C. § 2251(a) (production), and
United States v. X-Citement Video, Inc.,
. Wilson does not raise this argument with respect to his conviction for "knowingly transporting] an individual who has not attained the age of 18 years ... with intent that the individual engage in prostitution" under 18 U.S.C. § 2423(a). We note, without deciding, that other courts of appeals have held that section 2423(a) does not require that the defendant know the victim’s underage status.
See United States v. Jones,
. Section 728.12(1) reads
It shall be unlawful to employ, use, persuade, induce, entice, coerce, solicit, knowingly permit, or otherwise cause or attempt to cause a minor to engage in a prohibited sexual act or in the simulation of a prohibited sexual act. A person must know, or have reason to know, or intend that the act or simulated act may be photographed, filmed, or otherwise preserved ... in any other type of storage system.
