BERZON, Circuit Judge:
David Struckman was indicted for massive tax fraud and was hiding out in Panama. United States agents helped arrange his expulsion from his chosen sanctuary, and he was handed over to federal officials for prosecution. Struckman maintains that the government’s conduct, both in bringing him from abroad to stand trial in the United States and in its criminal investigation of him, warrants dismissal of the indictment with prejudice. In a painstakingly careful 83-page pretrial order, District Court Judge Takasugi1 determined that the government had engaged in misconduct with regard to the investigation but not the expulsion from Panama. The District Court suppressed a great deal of evidence as a result of its finding of misconduct but ruled that dismissal of the indictment against Struckman was not an appropriate remedy. We agree that the broad suppression of evidence before trial was an adequate remedy for the misconduct found, disturbing as some of it was, and therefore affirm.
I.
David Struckman was indicted in the Western District of Washington on May 11, 2004, for conspiracy to defraud the United States in violation of 18 U.S.C. § 371. The U.S. government later issued a superseding indictment, adding nine counts of tax evasion under 26 U.S.C. § 7201.
The superseding indictment alleged that Struckman was a co-founder of an organization called the Institute of Global [565]*565Prosperity. From 1996 to 2002, Global Prosperity offered, for a fee and through middlemen called “Qualified Retailers,” an audiotape/CD series and seminars. These products advocated the use of illegal means to avoid paying income tax, including “voluntary withdrawal” from the United States’ jurisdiction and the placement of assets in purported foreign or common law trusts without relinquishing control of them. The indictment alleged that Struckman purchased bogus trusts and fraudulently established bank accounts to receive profit distributions from Global Prosperity’s more than $40 million in gross receipts, and that Global Prosperity and Struckman never reported these distributions to the Internal Revenue Service (“IRS”) as income.
At some point, Struckman, a U.S. citizen, went to the Republic of Panama on a tourist visa and stayed. The U.S. government vigorously sought Struckman’s return to the United States to stand trial.
Before trial, Struckman filed motions to dismiss the indictment based on alleged due process violations or the district court’s supervisory powers. The motions focused on asserted illegalities and misconduct during the government’s efforts to secure his return from Panama but also relied on alleged misconduct during the criminal investigation in the United States. The district court held an evidentiary hearing on the motions and issued extensive factual findings, none of which is contested by the government on appeal. We begin by describing in detail the government’s conduct as found by the district court.
A. Struckman’s Departure from Panama
After Struckman went to Panama, U.S. government officials developed a plan for his return. Timothy O’Brien, at that time the regional security officer at the U.S. Embassy in Panama City, Panama, was the central person involved in the efforts to bring Struckman back to the United States for trial. In a 2004 e-mail to a Department of Justice (“DOJ”) trial attorney, O’Brien summed up the plan that had been developed:
What we’re hoping to do is find [Struck-man] and have him deported vice [sic] going the provisional arrest warrant route. The reasons for this are simple — a [provisional arrest warrant] will mean that extradition proceedings begin .... 2 There’s a Section of the [Code of Federal Regulations] ... that allows the [U.S. government] to revoke a passport of an individual who is the subject of an outstanding Federal Felony arrest warrant — which Struckman has. We know he’s got a U.S. [passport], and if we revoke it he’s undocumented. Which means he’s immediately deportable.
There’s also the possibility that the Panamanians can decide he’s an undesirable and revoke his visa .... We just had a meeting with the Panamanian National Police ..., and provided information that we hope will assist them in finding him....
[566]*566On August 25, 2004, Panama’s National Director for Immigration and Naturalization (“the Director”) issued two resolutions regarding Struckman’s immigration status. One resolution denied Struckman’s pending request to obtain an immigrant visa. It stated that the Panamanian government had considered a “note” it received from the U.S. District Court regarding the charge for conspiracy to defraud the United States.3 The resolution gave Struck-man thirty days to leave the country.
The companion resolution stated that Struckman was “wanted by the judicial authorities of the United States of America, in virtue of the fact that he ha[d] a warrant for his arrest pending for federal charges, being, as a result, a fugitive from United States justice.” Relying on Panamanian Law No. 16 of June 30, 1960, Article 37, the resolution stated that “[ijmmigration to the country of a foreign national is prohibited ... [for] all persons with criminal records, such as fugitives and those sentenced or defendant in common crimes.” The resolution ordered the arrest of Struckman “for reasons of security and public order.”
On June 23, 2005, O’Brien sent an e-mail to IRS Special Agent Michael D. Hardaway about how quickly Struckman could be obtained from Panama. He noted that Struckman “may be able to get a lawyer to slow things down (but that’s a big reason we want to move quickly if we nab him— we don’t want to give him that chance, especially with that much money available to him).” In a letter later that summer to Panamanian officials, O’Brien stated that Struckman was charged with “defrauding investors of over $50 million” and that he was attempting to perpetrate the “same kind of fraud scheme that he used with such success in the U.S.” in Panama. O’Brien had no factual basis for making this statement.
Shortly before Struckman was arrested by Panamanian authorities, O’Brien discussed the plan for the “expulsion” of Struckman with a DOJ trial attorney via email. He stated that “[w]hat we have set up, and still in place, is a [passport] revocation letter to be served on Struckman whenever he gets arrested” and that “[w]e also have a deportation/expulsion letter from Panamanian Immigration ready to go.” As to the delay, O’Brien noted that the plan had been “in place for a while, it’s just putting the habeas grabbus on [Struckman] that’s holding up executing everything.”
On January 11, 2006, the Panamanian National Police contacted O’Brien to report that police officers had arrested a man who might be David Struckman. O’Brien responded that Struckman “[had been] sentenced and at this moment is a fugitive of the federal authorities and is [awaiting] to serve his sentence.” The statement was clearly not true; Struck-man had not yet been tried.
As planned, that same day, the U.S. Department of State revoked Struckman’s passport and a Panamanian arrest order issued for Struckman’s failure to “maintain[ ] his legal documents in the national territory.” Struckman’s counsel in Panama immediately filed a habeas corpus lawsuit in Panamanian court.
The following day, O’Brien sent a fax to Mark Odulio, a federal prosecutor involved in the Struckman case. He informed Odulio that “[a] lawyer for Struckman came sniffing around police [headquarters] this morning, the race has begun[.][T]he Panamanian] N[ational] Pfolice] ha[ve] turned Struckman over to immigration, so they’ll [567]*567refer the lawyer to them some time today.” One day later, the district court found, “Struckman was deported from Panama.”
Panama’s Supreme Court of Justice issued an opinion in Struckman’s habeas case several months after Struckman was removed from the country. The opinion set forth information from the Director, including that Struckman’s “deportation from the national territory [was] made effective on January 13, 2006.” (Emphasis in original.) The Panamanian Court held that it could “not pronounce regarding the legality of [Struckman’s] arrest ... because [Struckman was then] outside the jurisdiction of Panama, due to the fact that he was deported in compliance” with a 2004 resolution providing for such measures.
B. The U.S. Government’s Investigation of Struckman
The IRS’s criminal investigation of Struckman dates at least to 2000. Struck-man’s claims of government investigatory misconduct focus on the actions of two IRS Special Agents, Keith L. Chinn and Michael D. Hardaway (the latter mentioned earlier in connection with Struckman’s transfer from Panama), as discussed below.
(1) Confidential informant “Ted”
Chinn was assigned in 2000 “to do some background information on” Struckman for an investigation of the Global Prosperity program. He made rough notes in September of that year about a meeting with an anonymous informant he designated “Ted.” Chinn’s notes indicate that “Ted” divulged personal information about Struckman, including addresses, marital history, a bank account number used by Struckman or his daughters, and other information about Struckman’s family. On at least eight later occasions between September 2000 and December 2001, Chinn made rough, contemporaneous notes about additional conversations with “Ted.” He did not generate contemporaneous Memoranda of Investigation (“MOIs”), the proper format for documenting agents’ contacts with informants, to memorialize these contacts. The information attributed to “Ted” in the notes is wide-ranging, including Social Security numbers for members of Struckman’s family, license plate numbers for vehicles at Struckman’s home, locations of safe deposit boxes, and Struckman’s daughter’s plan to move to a new residence, including her new address.
In March of 2001, Hardaway wrote an MOI detailing a conversation with “Ted,” the same confidential informant with whom Chinn had been in contact. Between April 17, 2001, and December 12, 2001, Hardaway wrote MOIs for nineteen additional contacts with “Ted.” In addition to personal information about Struckman’s family, the MOIs and rough notes used to produce them “include[d] reaction to grand jury appearances by [Struckman and his daughter], reaction to subpoenas by family members, Social Security Numbers, addresses to residences, expenditures, phone and fax numbers, transfer of funds, and arguments and marital problems among the family.”
On December 17, 2001, Hardaway sent an e-mail to Chinn requesting that he “finally finish those memos” regarding the information obtained from “Ted,” because Hardaway was “being asked[ ] by the attorneys” for the memos. Chinn later testified that he eventually generated after-the-fact MOIs for his contacts with “Ted,” although he did not specify when he did so. It is clear, however, that Chinn never produced additional MOIs for contact with “Ted” occurring after the December 2001 e-mail, and Hardaway produced only two more, dated January 3 and 8, 2002. None[568]*568theless, Hardaway and Chinn continued to attribute later-acquired information, including information that Struckman was in Panama and about his activities there, to “Ted” well after January 8, 2002.
Suspicious as to whether “Ted” existed, defense counsel before trial sought to discover “Ted’s” identity, arguing “that unless [‘Ted’] is in a very close relationship with defendant, the government would not have been able to obtain such information but for the use of illegal wiretaps.” The district court concluded that Struckman had made the requisite minimal threshold showing that the identity of “Ted” would be relevant to a defense of governmental misconduct requiring dismissal, and so ordered the government to produce “Ted” for an in camera hearing with the district judge. But, “Ted” proved catastrophe-prone: When Hardaway tried to serve the putative “Ted” with a subpoena for the hearing, he was told that the informant had recently fallen off a roof and might not be able to travel due to medical problems.
Stymied in its attempt to interview “Ted,” the court ordered the government to file “a declaration stating the identity of [‘Ted’], describing his/her connection to defendant Struckman and how the informant came about his/her knowledge concerning [the] defendant.” The response, filed by Department of Justice Tax Division trial attorneys Mark Odulio and Larry Wszalek, came in the form of MOIs by Chinn and Hardaway, not declarations from Chinn and Hardaway under penalty of perjury. The so-called MOIs were dated the same day as the government’s response was filed in the district court, so were not contemporaneous in any sense. In his MOI, Hardaway represented that he had confirmed the identity of the informant as Gary D. Moritz, who had indeed fallen from a roof and who was the husband of Struckman’s first wife, Bonnie Moritz. The government also submitted from Gary Moritz an unsworn statement that he had no recollection of any of the information that the government attributed to him.
Concerned that the filing did not include any declarations under penalty of perjury from the agents who knew “Ted’s” identity, the district court issued a second order requiring the government to produce a declaration regarding “Ted’s” identity. This time the government filed a document denominated by attorneys Odulio and Wszalek in their filing as a “declaration,” signed by Hardaway and Chinn but not under penalty of perjury. In the document, Hardaway and Chinn stated that “Ted” was Gary Moritz and asserted that they believed Moritz received most of the information from discussions at family gatherings or by listening to conversations between his wife, Bonnie Moritz, and her daughters with her ex-husband David Struckman.
In response, Struckman filed declarations under penalty of perjury by Gary Moritz, Bonnie Moritz, and one of Struck-man’s daughters, Jennifer Wininger. Gary Moritz stated that he did not recall giving information about Struckman to Hardaway and did not remember Struck-man. Moritz’s wife and Struckman’s daughter denied ever knowing much of the information attributed to Moritz. Also, the district court found, “Bonnie Moritz contradicted] almost every single statement attributed to her husband as [‘Ted’] ..., and in addition, statefd] that she and Jennifer discussed over the phone much of the private, family related information attributed to Gary as [‘Ted’] and that she believed her ‘phones were tapped in some manner during this time.’ ”
(2) Government relationship with Dave Bowden
In its investigation, the IRS also relied on Dave Bowden, operator of a car clean[569]*569ing business, who met Struckman in 1996 when Struckman brought in several cars to be cleaned. Bowden told the IRS that Struckman used $30,000 in cash to buy a car from Bowden and boasted that he sent his wife to the bank nearly every day to withdraw an amount under $10,000. In a grand jury proceeding in 2003 concerning Struckman’s wife, Laura, Bowden testified that he had given documents taken from Struckman’s car to Hardaway.
Before trial, Struckman moved to compel disclosure of material concerning Dave Bowden, including Bowden’s tax returns, audit file, “motivation for illegal black bag operations at the behest of the government,” and “past acts of perjury on tax forms.” The government at first denied that Bowden had been audited by the IRS, did not produce Bowden’s tax returns, and denied that Bowden had given photocopies of papers that he had taken from Struck-man’s car to Hardaway or any other IRS agents.
As it turned out, Bowden had in fact received notice of an audit from the civil division of the IRS in 2004 and contacted Hardaway about it soon afterwards. Hardaway then had contact with the auditor about Bowden’s audit, but never memorialized either his contact with Bowden or that with the auditor at the time, waiting until two days after the court-ordered motion to compel — nearly three years after the contact — to do so. Hardaway asserted that he had told the prosecutors “on several occasions,” the last time on the day after the court order compelling disclosure of information about Bowden’s audit, about his contacts. In declarations under penalty of perjury submitted to the district court, attorneys Wszalek and Odulio each acknowledged Hardaway’s post-disclosure order statement to them, but said that he did not recall any earlier disclosure by Hardaway about the audit contacts. One day after the court’s order compelling disclosure and the same day as Hardaway’s last disclosure to the prosecutors, the government changed its stance: The government “acknowledged it had made a ‘misstatement’ concerning the existence of an audit on Bowden” and that it had other exculpatory information concerning Bow-den’s contact with IRS agents.
Additionally, Bowden told IRS criminal investigation agents that he had taken documents from Struckman’s car in 1996 or 1997, on his own initiative, and that he had later given those documents, along with others Struckman had given directly to Bowden, to Hardaway. Bowden also recalled telling Hardaway how he had obtained the documents.
At the evidentiary hearing on the motion to dismiss, Hardaway continued to recall some contact with the IRS auditor but denied — contrary to testimony by the IRS agent assigned to audit Bowden — any recollection of an in-person meeting with the auditor about Bowden’s audit or of giving the auditor access to records that Bowden had given to Hardaway. He also initially denied any recollection of receiving the documents taken from Struckman’s car by Bowden. Only when Struckman’s counsel demanded them did Hardaway “remember” the existence of a box of documents related to the case that he had inexplicably kept apart from the other case documents.
C. Struckman’s Motions to Dismiss
After the evidentiary hearing on the motions to dismiss, the district court issued an 83-page order denying the motions. The district court first rejected Struck-man’s argument that the court did not have personal jurisdiction over him because of the manner in which he was brought from Panama, relying on the Ker/Frisbie doctrine. That doctrine provides generally that “the manner by which [570]*570a defendant is brought to trial does not affect the government’s ability to try him.” United States v. Matta-Ballesteros, 71 F.3d 754, 762 (9th Cir.1995) (citing Ker v. Illinois, 119 U.S. 436, 444, 7 S.Ct. 225, 30 L.Ed. 421 (1886) and Frisbie v. Collins, 342 U.S. 519, 522, 72 S.Ct. 509, 96 L.Ed. 541 (1952)), cert. denied, 519 U.S. 1118, 117 S.Ct. 965, 136 L.Ed.2d 850 (1997). Struck-man maintained that Panama had actually extradited, not deported him, and that the extradition did not comply with the Extradition Treaty between Panama and the United States, in which case the Ker/Frisbie doctrine would not apply.
As to Struckman’s motion to dismiss the indictment on grounds of misconduct in the investigation and in responding to discovery, the district court declared that the government had indeed committed serious Brady/Giglio violations.4 First, as to the informant “Ted,” the district court found that information regarding the identity of the informant submitted by Hardaway and Chinn right before trial was “remarkably different from their previous statements when it comes to details.” Disbelieving the agents’ ultimate submissions, the court concluded that:
[T]he sheer volume of discrepancies in the testimony of the agents who claim to have handled the informant, the degree of irregularities in the record concerning the alleged informant, as well as the uncontested testimony of [Bonnie Moritz and Jennifer Wininger] that Gary Moritz could not have been the informant, lead the court to find that there was no single source of information for all the information attributed to “Ted,” and that the source of all that information could not have been Gary Moritz.
While in isolation all these discrepancies could very well be attributed to sloppy record keeping, faulty memories, simple misstatements or minor omissions, in the aggregate, they add to nothing more than a house of cards built to support the illusion of the existence of [“Ted”].
Regarding the Bowden information, the district court similarly found that the government had been considerably less than forthcoming. There was a “secret deal” between Hardaway and Dave Bowden, the district court found, pursuant to which “[n]ot only was Bowden not prosecuted[on tax-related charges], but in return for his testimony in the Laura Struckman trial, and in the upcoming trial of David Struck-man, ... Hardaway prevented a proper audit of Dave Bowden by the civil branch of the IRS.” Also, the district court concluded that “[w]hile it may be a coincidence that the box of documents Bowden gave to SA Hardaway [was] simply kept out of the knowledge of the prosecutors, it is more likely that SA Hardaway was trying to maintain those records separate from the investigatory file in this case.” Because “the government ha[d] yet to produce the documents Bowden took and copied from defendant’s cars,” the court went on to declare that “given the pattern of misconduct in the case, ... the government should not be allowed to introduce[ ] those documents at trial.”
Despite its strong condemnation of the government and its finding of Brady/Giglio violations, the district court rejected Struckman’s motion to dismiss on Bra[571]*571dy/Giglio grounds. Instead, the court excluded evidence attributed to “Ted,” precluded Bowden from appearing as a witness at trial, excluded all evidence Bowden had taken from Struekman’s car, and required the government to assure that the evidence produced at trial was not “derived from suppressed evidence.” The district court did not make any finding as to whether the prosecutors — as opposed to the IRS investigators-engaged in affirmative misconduct.
Struckman proceeded to trial. O’Brien, Hardaway, and Chinn did not testify. Struckman was convicted of one count of conspiracy to defraud the United States under 18 U.S.C. § 871 and three counts of income tax evasion under 26 U.S.C. § 7201. He was sentenced to 70 months imprisonment and ordered to pay more than $2.9 million in restitution. The trial court never made further inquiry into the actual sources of the information attributed to “Ted,” and the government never revealed them.
Struckman now appeals the district court’s denial of his motions to dismiss the indictment.
II.
A. Jurisdictional Challenge
We first consider whether the district court lacked personal jurisdiction over Struckman because of the manner in which he was brought to the United States. “Jurisdictional issues are reviewed de novo, as are challenges to personal jurisdiction based on the alleged violation of an extradition treaty between the United States and another country.” United States v. Anderson, 472 F.3d 662, 666 (9th Cir.2006) (internal citation omitted).
Our starting point is the venerable principle that “the manner by which a defendant is brought to trial does not affect the government’s ability to try him.” Matta-Ballesteros, 71 F.3d at 762 (citing Ker, 119 U.S. at 444, 7 S.Ct. 225, and Frisbie, 342 U.S. at 522, 72 S.Ct. 509). We have, however, recognized exceptions to the Ker/Frisbie doctrine “if either: (1) the transfer of the defendant violated the applicable extradition treaty, or (2) the United States government engaged in ‘misconduct of the most shocking and outrageous kind’ to obtain his presence.” Anderson, 472 F.3d at 666 (quoting Matta-Ballesteros, 71 F.3d at 764 (internal citations omitted)).
(1) Violation of the Extradition Treaty
Seeking to come within the first Ker/Frisbie exception, Struckman maintains that he was taken from Panama to the United States in violation of the extradition treaty between the United States and Panama, and that dismissal is therefore required. See Providing for the Extradition of Criminals, U.S.-Pan., May 25, 1904, 34 Stat. 2851 (“Extradition Treaty”). We do not agree.
The U.S. government was indisputably involved in efforts to convince Panamanian authorities to deport Struck-man and facilitate his return. But persuasion and cooperation do not necessarily add up to extradition. “Neither deportation nor surrender other than in response to a demand pursuant to Treaty constitutes extradition.” Oen Yin-Choy v. Robinson, 858 F.2d 1400, 1404 (9th Cir.1988). Nations may in practice alter the process for extradition requests, but “[w]hile the formalities of extradition may be waived ..., a demand in some form by the one country upon the other is required, in order to distinguish extradition from the unilateral act of one country, for its own purposes, deporting or otherwise unilater[572]*572ally removing unwelcome aliens.” Stevenson v. United States, 381 F.2d 142, 144 (9th Cir.1967) (internal citation omitted); see also Michael Abbell, Extradition to AND FROM THE UNITED STATES § 7-2(2)-(4) (2008) (describing alternatives to extradition of criminal defendants, such as a request by the United States to another country for formal or “informal” deportation or, for U.S. citizens, passport revocation).
The government did not demand Struck-man’s surrender pursuant to the Extradition Treaty; indeed, the record reveals that the government went to great lengths to avoid doing so.5 Moreover, the Panamanian government in its Resolutions expressly relied on its own interests in deporting Struckman, not its responsibilities under the Extradition Treaty. As Struck-man was not extradited, his argument that his “extradition” was not in compliance with the procedures set forth in the treaty fails.
Although Struckman was not extradited, his transfer to the United States could still be prohibited by the Extradition Treaty, see United States v. Alvarez-Machain, 504 U.S. 655, 662, 112 S.Ct. 2188, 119 L.Ed.2d 441 (1992), if, for example, the Extradition Treaty made extradition the exclusive means to effect the cooperative transfer of a criminal defendant. In considering whether that was so here, we begin by looking to the Extradition Treaty’s express terms. See Alvarez-Machain, 504 U.S. at 663, 112 S.Ct. 2188. As in Alvarez-Machain, the Extradition Treaty does not provide that extradition is the exclusive means for one signatory to obtain a criminal defendant or fugitive from the territory of the other.6 Compare Providing for the Extradition of Criminals, U.S.-Pan., May 25, 1904, 34 Stat. 2851, with Extradition Treaty, May 4, 1978, U.S.-Mex., 31 U.S.T. 5059. In the Treaty with Panama, the signatories “agree to deliver up persons . who, having been charged with or convicted of any of the crimes and offenses specified in [the Extradition Treaty] ... shall seek ... asylum or be found within the territories of the other.” See Providing for the Extradition of Criminals, U.S.-Pan., art. I, May 25, 1904, 34 Stat. 2851. But what the countries are required to do when one signatory invokes the Treaty does not limit what they may agree to do cooperatively. Nowhere does the Treaty curtail the prerogative of Panama to deport U.S. citizens, nor does it “bar[] the signatories from informally cooperating with each other as they did in this case.” United States v. Mejia, 448 F.3d 436, 443 (D.C.Cir.2006), cert. denied, 549 U.S. 1137, 127 S.Ct. 989, 166
[573]*573L.Ed.2d 747 (2007).7
We hold that the Treaty does not prohibit the use of means other than extradition to obtain a defendant’s presence in the United States and did not bar Struck-man’s transfer to the United States. In so doing, we join all other circuits to have considered this issue concerning the reach of the Extradition Treaty with Panama. See Mejia, 448 F.3d at 443; United States v. Noriega, 117 F.3d 1206, 1213 (11th Cir.1997); United States v. Cordero, 668 F.2d 32, 37-38 (1st Cir.1981).
(2) Shocking and outrageous government conduct
Struckman next attempts to fit his quest for mandatory dismissal into the second exception to the Ker/Frisbie rule: Where the Government’s conduct to obtain a defendant’s presence is so shocking and outrageous “as to violate the universal sense of justice,” United States v. Barrera-Moreno, 951 F.2d 1089, 1092 (9th Cir.1991) (internal quotations omitted), the means of obtaining jurisdiction over the defendant amounts to a due process violation, and dismissal is required. See Anderson, 472 F.3d at 666.8 The government’s conduct meets this standard, Struckman argues, because the U.S. government interfered with his Sixth Amendment right to counsel while in Panama and induced the Panamanian government to deport him by making misrepresentations regarding his criminal status in the United States.
We review de novo the district court’s denial of Struckman’s motion to dismiss the indictment based on outrageous government conduct in connection with the government’s efforts to secure Struckman from Panama. See United States v. Holler, 411 F.3d 1061, 1065 (9th Cir.2005). “[W]e view the evidence in the light most favorable to the government and we accept the district court’s factual findings unless they are clearly erroneous.” United States v. Gurolla, 333 F.3d 944, 950 (9th Cir.), cert. denied, 540 U.S. 995, 124 S.Ct. 496, 157 L.Ed.2d 395 (2003).
We agree with the district court that dismissal was not required under the second Ker/Frisbie exception. Some of the government’s actions in Panama are quite disturbing, particularly the flat misstatements to Panamanian authorities. But a comparison to the circumstances in other cases in which the outrageous conduct exception was held inapplicable makes clear that the governmental conduct here does not meet the “extremely high standard” required for dismissal under the outrageous conduct / due process defense. [574]*574United States v. Smith, 924 F.2d 889, 897 (9th Cir.1991).
The involvement of U.S. government agents in facilitating the expulsion of Struckman from Panama and receiving him in the United States surely does not meet this standard. We have previously held, for example, that abduction of a defendant by U.S. Marshals from the defendant’s home was not so shocking and outrageous as to warrant dismissal. See Mattar-Ballesteros, 71 F.3d at 761, 763.
The lies told by O’Brien to Panamanian officials are considerably more troubling than other aspects of U.S. governmental involvement in Panama. We are not prepared to say that blatant lies to a foreign government that induce the foreign government to transfer a defendant to the United States when it otherwise would not could never amount to conduct so shocking and outrageous as to violate due process and require dismissal of pending criminal proceedings in the United States. In this case, though, the district court found that O’Brien’s misrepresentations came after the Panamanians had already decided to cooperate with the United States in returning Struckman and had issued the resolutions. So the Panamanians did not rely on these misrepresentations for that purpose. Also, Struckman was deported after his passport was revoked, which provided a separate reason for deportation under Panamanian law, in addition to those covered in the resolutions.
In Anderson, we declined to apply the Ker/Frisbie shocking and outrageous conduct exception because Costa Rica’s decision to extradite the defendant was not dependent on “representations made by United States government agents to Costa Rican authorities [that] may have misled Costa Rica into believing [the defendant] had an unserved prison sentence.” 472 F.3d at 667. Here, similarly, Struckman has not demonstrated prejudice from O’Brien’s misstatements, so there was no due process violation justifying dismissal of the charges.
Nor does it matter whether Struckman had a right under Panamanian law to appeal the deportation order against him or pursue a habeas proceeding. Anderson held in nearly identical circumstances that government behavior does not become outrageous because a defendant is removed from a foreign country pending his right of appeal. See id.
B. Dismissal Using Supervisory Powers
Our rejection of Struckman’s outrageous conduct/due process claim does not end our inquiry into the denial of the motion to dismiss because of the manner in which Struckman was brought to the United States from Panama. Even “if the [government’s] conduct does not rise to the level of a due process violation, [a] court may nonetheless dismiss [an indictment with prejudice] under its supervisory powers.” United States v. Chapman, 524 F.3d 1073, 1084 (9th Cir.2008) (internal quotations and brackets omitted). Courts may dismiss an indictment under their inherent supervisory powers “(1) to implement a remedy for the violation of a recognized statutory or constitutional right; (2) to preserve judicial integrity by ensuring that a conviction rests on appropriate considerations validly before a jury; and (3) to deter future illegal conduct.” Matta-Ballesteros, 71 F.3d at 763 (citing United States v. Simpson, 927 F.2d 1088, 1090 (9th Cir.1991)).9 The defendant must [575]*575demonstrate prejudice before the court may exercise its supervisory powers to dismiss an indictment. See Bank of Nova Scotia v. United States, 487 U.S. 250, 255, 108 S.Ct. 2369, 101 L.Ed.2d 228 (1988); United States v. Ross, 372 F.3d 1097, 1110 (9th Cir.2004) (citing United States v. Tucker, 8 F.3d 673, 674-75 (9th Cir.1993) (en banc)); United States v. Rogers, 751 F.2d 1074, 1077 (9th Cir.1985).
We review for abuse of discretion the district court’s denial of Struckman’s motion to dismiss based on the court’s supervisory powers. Ross, 372 F.3d at 1109.
(1) Violation of a recognized statutory or constitutional right
“Dismissal is appropriate when the investigatory or prosecutorial process has violated a federal constitutional or statutory right and no lesser remedial action is available.” Barrera-Moreno, 951 F.2d at 1092. This Court has also suggested that a violation of jus cogens norms of international law might serve as a basis for dismissal. Matta-Ballesteros, 71 F.3d at 764 n. 5. Struckman argues that the government violated his constitutional right to counsel and rights under jus co-gens norms. We disagree.
(a) Right to counsel
O’Brien’s actions in Panama did not violate Struckman’s right to counsel. Struckman did retain counsel, who filed a habeas petition on Struckman’s behalf shortly after Struckman’s arrest. Moreover, O’Brien’s own e-mail to a DOJ prosecutor,' dated the day before Struckman’s removal from Panama, stated that the Panamanian National Police had “turned Struckman over to immigration, so [the Police will] refer the lawyer to them some time today,” indicating that the expectation was that Struckman would have a chance to confer with counsel. Nor has Struckman introduced evidence that he asked for and was refused the opportunity to consult with retained counsel with regard to any pending or possible future proceedings, while he was in Panama or otherwise. Although there was certainly an effort to get Struckman out of the country before he had a chance to obtain a ruling from a court preventing his removal, that effort was not itself a denial of a right to counsel.
In short, there simply is no evidence that O’Brien denied Struckman’s asserted right to counsel, in the United States or abroad. We therefore need not consider the extent to which an individual outside the country enjoys federal constitutional protection of a right to counsel with respect to civil proceedings instituted by a foreign country in cooperation with the United States.
(b) Jus cogens norms
Struckman next argues that dismissal is appropriate under the court’s supervisory authority because the government violated jus cogens norms of international law, namely “violations of the right to habeas corpus in a foreign land, the right to coun[576]*576sel, the right to due process and the right of access to the courts.”
Jus cogens norms are a subset of “customary international law”; “customary international law” is defined as the “ ‘general and consistent practice of states followed by them from a sense of legal obligation.’ ” Siderman de Blake v. Republic of Argentina, 965 F.2d 699, 714 (9th Cir.1992) (quoting Restatement (Third) of the Foreign Relations Law of the United States § 102(2) (1987)). These norms, which are “derived from values taken to be fundamental by the international community,” id. at 715 (internal quotation omitted), “are binding on all nations, and can not be preempted by treaty,” Matta-Ballesteros, 71 F.3d at 764 n. 5. We have suggested that violation of jus cogens norms could provide a basis for dismissal under a court’s supervisory powers because, like statutory and constitutional laws, they are justiciable in our courts. Id.
Although he makes a general jus cogens assertion, Struckman has not developed the argument at all. “Courts ascertain customary international law ‘by consulting the works of jurists, writing professedly on public law; or by the general usage and practice of nations; or by judicial decisions recognizing and enforcing that law,’ ” Siderman de Blake, 965 F.2d at 714-15 (quoting United States v. Smith, 18 U.S. (5 Wheat.) 153, 160-61, 5 L.Ed. 57 (1820)), and must ask “whether the international community recognizes the norm as one ‘from which no derogation is permitted,’ ” id. at 715 (quoting Comm. of U.S. Citizens Living in Nicaragua v. Reagan, 859 F.2d 929, 940 (D.C.Cir.1988)). Despite this fairly exacting standard, Struckman has not provided any international law materials concerning the jus cogens rights he asserts, much less materials that address the application of the asserted rights under the circumstances of this case. In this sensitive and complex area, we decline to create out of whole cloth the detailed legal arguments, or discover on our own the array of international materials, that would be necessary to support Struckman’s “bare assertion[s].” Greenwood v. Fed. Aviation Admin., 28 F.3d 971, 977 (9th Cir.1994).10
(2) Preservation of judicial integrity and deterrence of illegal government conduct
Having determined that dismissal was not appropriate based on a violation of Struckman’s rights, we next consider whether dismissal might be appropriate to preserve judicial integrity or deter illegal government conduct. While a court may dismiss a prosecution “to preserve judicial integrity,” Matta-Ballesteros, 71 F.3d at 763, it does not under this rubric “have the authority to supervise out-of-court executive procedure in the absence of a constitutional or statutory violation.” Barrera-Moreno, 951 F.2d at 1092 (citing Simpson, 927 F.2d at 1090); see also Simpson, 927 F.2d at 1091 (“The supervisory power comprehends authority for the courts to supervise their own affairs, not the affairs of the other branches; rarely, if ever, will judicial integrity be threatened by conduct outside the courtroom that does not violate a federal statute, the Constitution or a procedural rule.”). Moreover, to dismiss an indictment on this basis, a court must find that [577]*577the prosecutorial misconduct was “flagrant.” Id. at 1091. Similarly, a finding that the government has broken the law in the past is a necessary predicate to dismissal on the basis of deterrence of illegal government conduct. See id.
We have already concluded that the district court did not abuse its discretion in holding that Struckman has not established any violation of U.S. laws or jus cogens norms in securing Struckman for trial. The court made no finding, either, of prosecutorial misconduct with regard to the removal from Panama on which dismissal could have hinged in the absence of illegality, nor do we see a basis for such a finding in the record. We therefore affirm the district court’s refusal to dismiss on preservation of judicial integrity or deterrence of illegal government conduct grounds.
C. Remedy for Brady/Giglio Violations
Finally, we turn to Struckman’s contention that the exclusion of (1) all evidence attributed to “Ted,” (2) Dave Bowden as a witness at trial, (3) evidence taken from Struckman’s car by Bowden and not disclosed at the time of the district court’s order, and (4) evidence “derived from” the suppressed evidence was insufficient to cure the government’s Brady/Giglio violations. We affirm the denial of dismissal as a remedy.
“[R]emedies should be tailored to the injury suffered from the constitutional violation and should not unnecessarily infringe on competing interests.” United States v. Morrison, 449 U.S. 361, 364, 101 S.Ct. 665, 66 L.Ed.2d 564 (1981). “Because it is a drastic step, dismissing an indictment is a disfavored remedy.” United States v. Rogers, 751 F.2d 1074, 1076-77 (9th Cir.1985) (citing United States v. Blue, 884 U.S. 251, 255, 86 S.Ct. 1416, 16 L.Ed.2d 510 (1966)). Nonetheless, our circuit has recognized that dismissal with prejudice may be an appropriate remedy for a Brady or Giglio violation using a court’s supervisory powers where prejudice to the defendant results and the prosecutorial misconduct is flagrant. See United States v. Williams, 547 F.3d 1187, 1202 (9th Cir.2008); Chapman, 524 F.3d at 1077, 1086. We review for an abuse of discretion the district court’s decision whether to dismiss the indictment to cure prejudice resulting from such misconduct. See Chapman, 524 F.3d at 1084.
“The pivotal question under Brady and Giglio is whether the evidence withheld from the jury is material,” Libberton v. Ryan, 583 F.3d 1147, 1163 (9th Cir.2009), i.e., whether there is a “ ‘reasonable probability of a different result,’ ” id. (quoting Kyles v. Whitley, 514 U.S. 419, 434, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995)) (internal quotation omitted). Struckman did not order a trial transcript. It is, therefore, impossible for us to review the efficacy of the district court’s suppression order to cure any trial prejudice to Struckman. See Syncom Capital Corp. v. Wade, 924 F.2d 167, 169 (9th Cir.1991) (dismissing an appeal for failure to provide a trial transcript because the petitioner’s “main contentions ... depended] for their resolution on an examination of the facts elicited at trial”).
Struckman concedes as much, stating in his brief that the “principal problem” was the use of “illicitly-procured and falsely-attributed information ... to obtain [his] indictment or personal jurisdiction ... rather than for evidence at trial.” (Emphasis added.) But the “animating purpose of Brady is to preserve the fairness of criminal trials.” Morris v. Ylst, 447 F.3d 735, 742 (9th Cir.2006). Thus, a prosecutor’s duty is “to disclose evidence favorable to the accused that, if [578]*578suppressed, would deprive the defendant of a fair trial.” United States v. Bagley, 473 U.S. 667, 675, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985). Struckman’s contentions with respect to his indictment and personal jurisdiction are, therefore, not properly characterized as Brady or Giglio violations.11 We discussed above why Struckman’s challenge to personal jurisdiction does not require or permit dismissal. Moreover, even assuming the indictment process was deficient for its reliance on unlawfully obtained evidence, that deficiency was cured when Struckman was convicted by a jury after trial that excluded all of the suppressed evidence. See United States v. Mechanik, 475 U.S. 66, 70, 106 S.Ct. 938, 89 L.Ed.2d 50 (1986); United States v. Navarro, 608 F.3d 529, 539-40 (9th Cir.2010); United States v. Du Bo, 186 F.3d 1177, 1180 n. 1 (9th Cir.1999); People of the Territory of Guam v. Muna, 999 F.2d 397, 399 (9th Cir.1993).
III.
We stress that our affirmance of the district court’s careful rulings and remedy in this disturbing case in no way condones the actions of Chinn, Hardaway, or O’Brien or the prosecutors’ failure to discover and disclose the misconduct and misrepresentations of the government agents in this case, even absent affirmative prosecutorial misconduct. We are also deeply troubled by defense counsel’s assertions at oral argument, not countered by government counsel then or since, that even by the time of Struckman’s sentencing, the executive branch had not investigated any of the misconduct documented by the district court. But, as described above and in detail in the district court’s careful order, the authority directly to sanction this behavior does not lie with the courts; we can only assure that the misconduct does not give the government an advantage in obtaining a conviction. The district court’s extremely broad, pre-trial suppression order was sufficient to provide this assurance here.
For the foregoing reasons, we AFFIRM.
