    UNITED STATES OF AMERICA,

    v.                                          (D.C. No. 00-CR-38-W)
    SALVADOR FAVELA-FAVELA                                     (W. D. Oklahoma)
    Defendant - Appellant.
    ORDER AND JUDGMENT               *
    Before EBEL , MCWILLIAMS , and HENRY , Circuit Judges.
    Salvador Favela-Favela was convicted after a jury trial of        two counts of
    transporting illegal aliens in the United States, violations of 
    8 U.S.C. § 1324
    (a)(1)(A)(ii). On appeal, Mr. Favela advances the following arguments: (1)
    that the district court erred in denying his motion to suppress evidence obtained
    during a February 16, 2000 traffic stop; (2) that the evidence was insufficient to
    support his convictions; (3) that the government violated         Brady v. Maryland , 373
    *
    This order and judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. The court
    generally disfavors the citation of orders and judgments; nevertheless, an order
    and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
    U.S. 83 (1963), by failing to timely disclose evidence that would have allowed
    impeachment of a government witness; (4) that the government violated his due
    process and Sixth Amendment rights by allowing the deportation of material
    witnesses prior to trial; (5) that the district court issued several erroneous
    evidentiary rulings; and (6) that the district court’s cumulative errors warrant
    reversal. We are not persuaded by Mr. Favela’s arguments and therefore affirm
    his convictions.   1
    I. BACKGROUND
    At approximately 9:50 a.m. on February 16, 2000, Clinton, Oklahoma
    police officer Michael Nabors observed a Ford van traveling northbound on a
    road near Interstate-40. At the suppression hearing, Officer Nabors testified that
    he could see that there were two people in the front seat of the van and that the
    driver was an Hispanic male. Officer Nabors also noticed that there was a female
    passenger who was sitting in between the front two seats in the van and was not
    wearing a seatbelt. Officer Nabors explained that this passenger seemed to be
    sitting on her knees. He therefore concluded that she was not wearing a seatbelt
    1
    We also grant the following motions: the government’s motion to
    supplement the record (with the transcripts of the video depositions of Messrs.
    Cabanzo-Sanchez and Castillo-Estrada); (2) the appellant’s motion to supplement
    the record with exhibits.
    -2-
    and was thus violating Oklahoma law. 2
    Officer Nabors stopped the van. As he stood near the driver’s door, he
    noticed that there were about twenty people inside. According to Officer Nabors,
    the people in the van “really didn’t look at me, they looked straightforward as if
    to not make eye contact, just kind of stared straight forward.” Rec. vol. II, at 12
    (Tr. of Motions Hr’g, July 5, 2000). 3
    Officer Nabors asked the driver for his license and insurance verification.
    The driver produced a Texas license, which identified him as the defendant
    Salvador Favela-Favela. Mr. Favela then stepped out of the van, and Officer
    Nabors began to question him.
    At the suppression hearing, Officer Nabors described the sequence of
    questions as follows. First, he asked Mr. Favela if he was on a trip, and Mr
    Favela responded affirmatively. Then, the officer asked if the van’s passengers
    were family members or if they were on a church function. To both those
    questions, Mr. Favela said. “No.” Then, he asked Mr. Favela “if everybody in the
    van was ‘legal.’” 
    Id. at 11
    . Mr. Favela responded, “No,” but he added that the
    2
    Oklahoma law provides that, with certain exceptions, “Every operator
    and front seat passenger of a passenger car operated in this state shall wear a
    properly adjusted and fastened safety seat belt system, required to be installed in
    the motor vehicle when manufactured.” Okla Stat. tit. 47, § 12-417(A).
    3
    Officer Nabors further explained, “[U]sually you stop a vehicle and
    people want to stare at you, find out what’s going on. These people didn’t seem
    to do that.” Rec. vol. II, at 12.
    -3-
    passengers were “good people” who “weren’t causing anybody any problems” and
    “were just trying to . . . find work.” Id. at 13. Mr. Favela asked Officer Nabors
    to give him a break and let the passengers go.
    Officer Nabors replied that he needed to keep asking questions. He
    inquired whether the passengers were paying Mr. Favela. Mr. Favela responded
    that each passenger had paid him approximately $180.00.
    At that point, Officer Nabors asked Mr. Favela to return to the van and
    wait. Officer Nabors then called his supervisor, Sergeant Gene Kelly. At the
    suppression hearing, Sergeant Kelly testified that, upon arriving at the scene, he
    too questioned Mr. Favela. He said that in response to his question as to whether
    the passengers were “legal,” Mr. Favela again responded negatively.
    The officers took Mr. Favela and the passengers to the Clinton police
    station and contacted the Immigration and Naturalization Service (INS). Mr.
    Favela volunteered the following information to Sergeant Kelly: that he had
    made twenty other trips from Arizona to Georgia and Florida, that they were
    going to the latter two states because the fruit crop and construction business
    were doing well, that this was the first time he had been stopped, and that another
    person told him where to pick up his passengers.
    INS Agents Rodney McDonald and Eugene Graham arrived at the police
    station shortly thereafter. They told Mr. Favela that he was under arrest and read
    -4-
    him the Miranda warnings in Spanish. The INS agents also presented Mr. Favela
    with two “Lujan-Castro” waiver forms, one in English and one in Spanish. See
    United States v. Lujan-Castro, 
    602 F.2d 877
     (9th Cir. 1979). Mr. Favela signed
    the waiver form that was written in Spanish. 4
    After Mr. Favela signed the Lujan-Castro waiver, eighteen out of the
    twenty passengers were returned to their country of origin. As to the other
    two—Manual Cabanzo-Sanchez and Jorge Alberto Castillo-Estrada, the
    government took video depositions.
    Prior to trial, Mr. Favela filed a motion to suppress the evidence obtained
    by the government following Officer Nabors’ stop of the van. He presented the
    following arguments: (1) that Officer Nabors lacked probable cause to stop van
    initially; (2) that Officer Nabors’ questions were unduly intrusive; (3) that the
    questioning conducted by Sergeant Kelly at the Clinton police station before
    Miranda warnings were given violated Mr. Favela’s Fifth Amendment rights; (4)
    4
    The Lujan-Castro form advised Mr. Favela that: (1) he had the right to
    require temporary detention of illegal aliens who might serve as witnesses; (2) if
    he did not require the witnesses to stay, they would be returned to their country of
    origin and could not later be returned for trial; (3) if the witnesses remained in the
    United States at his request, they would do so under the supervision of the United
    States and at the cost of the United States; (4) these witnesses could be called to
    testify for him or for the government; (5) he had the right to have a lawyer assist
    him in making the decision to retain or release witnesses and that, if he could not
    afford a lawyer, one would be appointed for him; and (6) he and his lawyer had
    the right to speak to the witnesses before his trial.
    -5-
    that the testimony of Mr. Cabanzo-Sanchez and Mr. Castillo-Estrada (the two
    passengers who were not deported) should not be admitted at trial because the
    government permitted them to avoid permanent detention in exchange for their
    trial testimony; and (5) that the deportation of the eighteen other passengers
    violated his constitutional rights.
    The district court rejected the first, second, fourth, and fifth arguments. It
    concluded that there was probable cause for the initial stop, that the scope of
    Officer Nabors’ questions was reasonable, that Mr. Cabanzo-Sanchez and Mr.
    Castillo-Estrada could testify at trial because “[n]o evidence was presented that
    the will of either [man] was overborne or that their statements were the product of
    impermissible government acts or threats,” and that Mr. Favela had signed the
    Lujan-Castro form waiving his right to present testimony from the eighteen other
    passengers. See Rec. vol. I, doc. 77, at 15-16 (District Court Order, filed July 12,
    2000).
    However, the court also concluded that Sergeant Kelly had questioned Mr.
    Favela about ownership of the van before Miranda warnings were issued and that,
    at the time of this questioning, Mr. Favela was in custody and under interrogation.
    Thus, “[a]ny statements made by [Mr.] Favela to Sergeant Kelly at the police
    station were obtained in violation of Miranda and [Mr.] Favela’s Fifth
    Amendment right against self-incrimination and will therefore be suppressed.”
    -6-
    Id. at 14-15.
    At trial, the government presented video depositions from Mr. Cabanzo-
    Sanchez and Mr. Castillo-Estrada. Mr. Sanchez testified that he crossed the
    border from Mexico without permission of the United States government, that he
    walked from the border to Phoenix, and that friends made arrangements for his
    transportation with Mr. Favela. Mr. Estrada gave similar testimony.
    Agent McDonald provided testimony about unlawful entry into the United
    States. He testified that the area at which Mr. Sanchez crossed the border was a
    common staging area for illegal immigrants. He added that Mr. Favela had a
    phone book with a phone number for Altar Sonora, Mexico. According to Agent
    McDonald, this location is also a staging area for Mexican aliens to cross into the
    United States.
    Mr. Favela’s defense was that he had a legitimate transportation company
    and that he did not know of the illegal status of his passengers. He offered
    testimony from the Assistant Manager of the Union Bus Station in Oklahoma City
    that Greyhound did not have a policy of checking into the immigration status of
    passengers.
    Mr. Favela also sought to minimize the import of his statements to Officer
    Nabors and Sergeant Kelly. He offered testimony from a social worker and
    family friend that his knowledge of English was limited.
    -7-
    Finally, Mr. Favela offered expert testimony from a former police officer,
    Theodore Montgomery. Mr. Montgomery testified that, if a person was sitting
    between the front seats of the van, Officer Nabors could not have seen that
    person.
    II. DISCUSSION
    A. Denial of Motion to Suppress
    In reviewing the denial of a motion to suppress, we examine the district
    court’s factual findings for clear error.   United States v. Le , 
    173 F.3d 1258
    , 1264
    (10th Cir.1999). We view the record in the light most favorable to the
    government. 
    Id.
     The ultimate question of whether the government’s conduct was
    reasonable under the Fourth Amendment is a legal question that we consider de
    novo. 
    Id.
    In this appeal, Mr. Favela challenges both the initial traffic stop and the
    questioning by Officer Nabors leading up to Mr. Favela’s statement that the
    occupants of the van were not “legal.” We examine each argument separately.
    1. Initial Stop
    Under the Fourth Amendment, a traffic stop constitutes a seizure and
    therefore must be “reasonable.”       Delaware v. Prouse , 
    440 U.S. 648
    , 653 (1979).
    -8-
    A stop is reasonable if it is based on an observed traffic violation or a reasonable
    articulable suspicion that such a violation has occurred or is occurring.   United
    States v. Botero-Ospina , 
    71 F.3d 783
    , 787 (10th Cir. 1995) (en banc). Reasonable
    suspicion is “a particularized and objective basis” for suspecting the person
    stopped of criminal activity.   United States v. Cortez , 
    449 U.S. 411
    , 417-418
    (1981); see also United States v. Callarman , 
    273 F.3d 1284
    , 1286 (10th Cir. 2001)
    (“While either probable cause or reasonable suspicion is sufficient to justify a
    traffic stop, only the lesser requirement of reasonable suspicion is necessary.”).
    Mr. Favela first argues that “[n]o reasonable officer could have observed a
    seatbelt violation under the scenario suggested by [Officer] Nabors.” Aplt’s Br.
    at 27. He maintains that the record establishes that the traffic stop was made
    because of Mr. Favela’s Hispanic heritage rather than because of Officer Nabor’s
    observations of a seatbelt violation. In support of this argument, Mr. Favela lists
    various inconsistencies between Officer Nabors’s statements at the preliminary
    hearing, the motion to suppress hearing, and the trial. He points to differences in
    the officer’s account of the order in which he asked questions and in whether the
    questions were asked when Mr. Favela was still in the van or when he stepped out
    of it. Mr. Favela also notes that Sergeant Kelly admitted on cross-examination
    that “the nationality of the people sitting in front of the van” was “a predominant
    factor in [his] decision to ask whether or not they were legal.” Aplt’s Br. at 21
    -9-
    (citing Rec. vol II, at 104).
    We are not convinced by Mr. Favela’s challenge to the initial stop. Here,
    the district court made the factual finding that Officer Nabors observed an
    unrestrained passenger in the front seat area of the van. None of the evidence
    noted by Mr. Favela establishes that this finding was clearly erroneous. In light
    of this factual finding, the accompanying legal conclusion is justified: Officer
    Nabors had “a particularized and objective basis,” see Cortez , 
    449 U.S. at 417-418
    , for suspecting a violation of the Oklahoma seatbelt law. 5
    Like the district court, we are not convinced that statements by Officer
    Nabors and Sergeant Kelly that they noticed the ethnic appearance of Mr. Favela
    and the passengers rendered the traffic stop unreasonable under the Fourth
    Amendment. The fact that both officers noticed the ethnic appearance of Mr.
    Favela and his passengers does not establish that it was that appearance—rather
    than the reasonable suspicion of a traffic violation—that led to the initial stop.
    Moreover, “[w]hen determining whether an officer possessed a reasonable
    articulable suspicion, the subjective motivations of an arresting officer are
    5
    At oral argument, the parties noted that there was some dispute as to the
    proper legal interpretation of the Oklahoma seatbelt law, as applied to facts at
    issue here (i.e., a passenger in the middle of the front seat). However, Mr.
    Favela’s counsel explained that, in this appeal, he is not challenging Officer
    Nabors’s interpretation of the statute. Instead, counsel stated, Mr. Favela’s
    argument is that the record does not support the district court’s finding that
    Officer Nabors actually saw a woman kneeling in the front seat of the van.
    -10-
    irrelevant.” Callarman, 
    273 F.3d at
    1286 (citing Botero-Ospina, 
    71 F.3d at 787
    );
    see also Whren v. United States, 
    517 U.S. 806
    , 813 (1996) (adopting an objective
    approach). Thus, even if the officers’ statements were some evidence of a bias
    against Hispanics (an inference the record does not support), the fact that Officer
    Nabors had a reasonable basis to suspect a violation of the Oklahoma seatbelt law
    establishes that the stop of the van was reasonable under the Fourth Amendment.
    2. Continuing Detention
    Mr. Favela further argues that, once Officer Nabors made the initial stop,
    he had no legitimate basis for the questioning about the identity of the passengers
    or their immigration status. Again, he maintains that Officer Nabors’s motivation
    was race-based, and that the continuing detention therefore violated the Fourth
    Amendment. We analyze this argument under the framework set forth in Terry v.
    Ohio, 
    392 U.S. 1
    , 20 (1968), asking whether Officer Nabor’s continuing detention
    of Mr Favela “was reasonably related in scope to the circumstances which
    justified the interference in the first place.” see Botero-Ospina, 
    71 F.3d at 786
    .
    Under the Fourth Amendment, a police officer conducting a traffic stop
    may request vehicle registration and a driver’s license, run a computer check, and
    issue a citation. United States v. Hunnicutt, 135 F.3d at 1345, 1349 (10th Cir.
    1998). He or she may also ask about “travel plans . . . and the ownership of the
    -11-
    car.” United States v. Rivera, 
    867 F.2d 1261
    , 1263 (10th Cir. 1989). However,
    after the officer has issued the citation and the driver has produced a valid license
    and proof that he is entitled to operate the car, the officer must allow him to
    proceed on his way without further delay. United States v. Holt, 
    264 F.3d 1215
    ,
    1221 (10th Cir. 2001) (en banc). In two circumstances, the officer may engage in
    additional questioning: (1) if he or she “has an objectively reasonable and
    articulable suspicion that illegal activity has occurred or is occurring;” and (2) if
    the subject of the additional interrogation consents to it. United States v.
    Gonzalez-Lerma, 
    14 F.3d 1479
    , 1483 (10th Cir. 1994) (citation omitted).
    In assessing what constitutes an objectively reasonable suspicion of illegal
    activity, we defer to “the ability of a trained law enforcement officer to
    distinguish between innocent and suspicious actions.” See United States v.
    McCrae, 
    81 F.3d 1528
    , 1534 (10th Cir. 1996) (internal quotation marks omitted).
    We assess the officer’s conduct in the light of common sense and ordinary human
    experience, considering the totality of the circumstances. United States v.
    Melendez-Garcia, 
    28 F.3d 1046
    , 1051 (10th Cir. 1994).
    This traffic stop jurisprudence does not support Mr. Favela’s argument.
    Officer Nabor’s initial questions to Mr. Favela concerned his travel plans (i.e. “if
    [Mr. Favela was on a trip, . . . if [the passengers] were all his family[,] . . . [and]
    if it was a church function [or] church group”). See Rec. vol. II, at 11. As part
    -12-
    of the initial inquiry during a legitimate traffic stop, these questions were not
    unduly intrusive. See United States v. West, 
    219 F.3d 1171
    , 1176 (10th Cir.
    2000) (“[Q]uestions about travel plans are routine and may be asked as a matter
    of course without exceeding the proper scope of a traffic stop”) (internal
    quotation marks omitted).
    The next question asked by Officer Nabors—whether the passengers were
    “legal”—cannot be so easily characterized as a routine question about travel
    plans. However, at the time that he asked that question, Officer Nabors had
    several grounds for suspecting illegal activity.
    First, Mr. Favela’s negative answers to the questions about whether the
    passengers were family members or a church group eliminated two lawful
    activities that could explain the presence of such a large number of people in the
    van. Second, Officer Nabors testified that he had learned of several instances in
    which vans or other large vehicles had been stopped and officers had discovered
    illegal aliens being transported across the country. See Rec. vol II, at 6. Some
    of these stops had been made by the Clinton, Oklahoma Police Department.
    Based on the totality of the circumstances confronting him, we conclude
    that Officer Nabors’s question about the immigration status of the passengers was
    justified by his observations. See United States v. Santana-Garcia, 
    264 F.3d 1188
    , 1193 (10th Cir. 2001) (holding that motorists’ negative response to the
    -13-
    question “whether they were ‘legal’” established probable cause to arrest them
    “for suspected violation of federal immigration law”) ; United States v. Salinas-
    Calderon, 
    728 F.2d 1298
    , 1301 n.3 (10th Cir. 1984) (stating that “[a] state trooper
    has general investigatory authority to inquire into possible immigration
    violations”). We therefore conclude that Officer Nabors’s questioning and the
    continuing detention of Mr. Favela did not violate the Fourth Amendment.
    B. Sufficiency of the Evidence
    Mr. Favela argues that the evidence is insufficient to support his
    convictions. This is a question of law that we examine de novo. United States v.
    Magleby, 
    241 F.3d 1306
    , 1311 (10th Cir. 2001). We must determine “whether
    taking the evidence—both direct and circumstantial, together with the reasonable
    inferences to be drawn therefrom—in the light most favorable to the government,
    a reasonable jury could find the defendant guilty beyond a reasonable doubt.”
    United States v. Hanzlicek, 
    187 F.3d 1228
    , 1239 (10th Cir. 1999). We will
    disturb the jury’s verdict only if our review leads us to conclude that no
    reasonable jury could have found beyond a reasonable doubt that the defendant
    was guilty of the crimes charged. 
    Id.
    Mr. Favela was charged with and convicted of violating 
    8 U.S.C. § 1324
    (a)(1)(A)(ii), which makes it illegal for “[a]ny person who . . . knowing or in
    -14-
    reckless disregard of the fact that an alien has come to, entered, or remains in the
    United States in violation of law, transports, or moves or attempts to transport or
    move such alien within the United States by means of transportation or otherwise,
    in furtherance of such violation of law.” In order to establish a violation of §
    1324(a)(1)(A)(ii), the government must prove: (1) that the defendant transported
    or moved an alien within the United States, (2) that the alien was present in
    violation of law, (3) that the defendant was aware of the alien’s status, and (4)
    that the defendant acted willfully in furtherance of the alien’s violation of the
    law. See United States v. Barajas-Chavez, 
    162 F.3d 1285
    , 1289 (10th Cir. 1999)
    (en banc).
    Here, Mr. Favela concedes that the government established the first two
    elements. See Aplt’s Br. at 38. However, he argues that the government did not
    prove beyond a reasonable doubt that he knew of the passengers’ illegal status or
    that he acted willfully.
    In support of this contention, he first argues that his answer to the question
    whether the passengers were “legal” was ambiguous. According to Mr. Favela, he
    could have been referring to the passengers not wearing seatbelts or to there being
    too many people in the van. Similarly, he maintains that his reference to the
    passengers being “good people” was evidence that he believed that they were in
    the country legally. Aplt’s Br. at 37. In general, he asserts that, in light of his
    -15-
    limited understanding of English, little weight should be given to his responses to
    the Clinton police officers’ questions.
    Mr. Favela also points to evidence supporting an inference of a good faith
    belief that the passengers were legally in the country. He observes that he picked
    up his passengers far north of the border, that he had no previous contact with
    them, that many people were traveling lawfully during this time in order to obtain
    work, and that it was customary for people to travel in groups. Mr. Favela also
    points to several factors that support the inference that he ran a legitimate
    transportation business: the van was not constructed to hide passengers, he
    traveled during the day, he obtained a liability policy providing extensive
    coverage in case of an accident, and the van was registered properly.
    We are not convinced by Mr. Favela’s arguments. The facts to which he
    directs us establish only that the evidence is conflicting as to his state of
    knowledge. As the government observes, there are also facts that controvert Mr.
    Favela’s interpretation. For example, the alien witnesses testified that, only a few
    days after their arrival in the United States, Mr. Favela picked them up, along
    with the other passengers, at a unfurnished two-to-three room trailer in Phoeniz,
    Arizona, some 1,231 miles away from Huntsville, Texas (where Mr. Favela
    usually resided). Additionally, Mr. Favela’s van contained a subscriber
    agreement for a cellular telephone, which listed a false address in Florida as Mr.
    -16-
    Favela’s home address. A jury could reasonably view these facts as supporting
    the government’s contention that Mr. Favela knew that he was transporting illegal
    aliens.
    More importantly, Mr. Favela gave incriminating answers to the Clinton
    police officers’ questions about the passengers, admitting that they were not
    “legal” and asking the officers to give the “good people” a break. Although these
    answers are arguably ambiguous, any such ambiguities merely presented factual
    questions for the jury to resolve. United States v. Horn, 
    946 F.2d 738
    , 743 (10th
    Cir. 1991) (noting that a rational jury could interpret ambiguous testimony in
    favor of the government).
    Because we must view the record in the light most favorable to the
    government, see Hanzlicek, 
    187 F.3d at 1239
    , we conclude that the evidence is
    sufficient to support Mr. Favela’s convictions.
    C. Brady Claim
    Mr. Favela argues that the INS withheld material, exculpatory evidence in
    violation of Brady v. Maryland , 
    373 U.S. 83
     (1963) . The evidence in question is
    a false resident alien card and a false social security card possessed by Mr.
    Estrada, one of the passengers whose video deposition was taken and played at
    trial. Mr. Favela states that he did not learn of these false documents until the
    -17-
    July 5, 2000 suppression hearing, well after Mr. Estrada had been returned to
    Mexico and was no longer available.
    According to Mr. Favela, this evidence was material because it would have
    shown that he lacked knowledge that the passengers were illegal aliens (i.e., if
    they appeared to have legitimate documents, then Mr. Favela could not have
    committed the charged offenses knowingly and willingly). Mr. Favela also
    asserts that he could have used the evidence to impeach Mr. Estrada (by
    suggesting that, because he had false documents, he may have testified falsely
    about other matters).
    In order to establish a Brady violation, a defendant must demonstrate that
    (1) the prosecution suppressed evidence, (2) the evidence was favorable to the
    defendant, and (3) the evidence was material. United States v. Quintanilla, 193
    F.3d at 1139, 1149 (10th Cir. 1999); see also Brady, 
    373 U.S. at 87
    . Evidence is
    material under Brady if there is a “reasonable probability that, had the evidence
    been disclosed to the defense, the result of the proceeding would have been
    different.” United States v. Bagley, 
    473 U.S. 667
    , 682 (1985).
    Here, the evidence in question (the false identification documents) was
    introduced at trial—through INS Special Agent Stephen Merrill. Thus, the only
    difference in what would have happened if the INS had timely disclosed these
    documents before Mr. Estrada’s video deposition is that Mr. Favela’s counsel
    -18-
    could have confronted the witness with them directly, rather than indirectly, by
    challenging Mr. Favela’s credibility in closing argument. See Aples’ Br at 44-45
    (noting that Mr. Favela’s lawyer mentioned in his closing argument that none of
    the passengers “had . . . papers”).
    Mr. Favela has failed to demonstrate a reasonable probability that this
    difference in the means of impeachment would have affected the result of the
    trial. Thus, the withheld evidence lacks materiality and his Brady argument is
    without merit.
    D. Deportation of Potential Witnesses
    Mr. Favela argues that the immediate deportation of eighteen out of the
    twenty passengers violated his due process and Sixth Amendment rights by
    depriving him of material evidence and by failing to provide him with an attorney
    before he waived the right to delay deportation.
    Mr. Favela’s argument is undermined by the language of the waiver form
    that he signed.    See Rec. vol. I, doc. 77, at 6-7 n.11 (District Court Order, filed
    July 12, 2000). That form, presented to Mr. Favela in Spanish and signed by him,
    states that Mr. Favela waives his right to delay the witnesses’ deportation and also
    informs him that he has a right to a government appointed lawyer to advise him
    on the decision:    See 
    id.
     (noting that the form stated, “You have the right to have
    -19-
    a lawyer assist you at this time in making this decision to retain or release these
    witnesses; if you cannot afford a lawyer, the United States government will
    provide you one at no cost to you.”).
    Mr. Favela argues in conclusory fashion that the waiver is invalid.    See
    Aplt’s Br. at 44. His conclusory statements are not sufficient to overcome the
    waiver. See Lujan-Castro, 
    602 F.2d at 878
     (affirming the district court’s finding
    that a similar waiver was knowingly and voluntarily executed and stating that
    “[t]he district court’s conclusion that the waiver was knowingly and intelligently
    executed is a finding of fact that may not be disturbed unless clearly erroneous”).
    Moreover, Mr. Favela has failed to establish that any of the eighteen passengers
    who were deported could have provided exculpatory evidence.
    We therefore conclude that the deportation of the eighteen witnesses did
    not violate Mr. Favela’s right to counsel or his due process rights.
    E. Evidentiary Rulings
    Mr. Favela sets forth a list of alleged evidentiary errors: (a) allowing the
    government to use “buzzwords” like “smuggler,” “safehouse,” and “staging area,”
    see Aplt’s Br.at 47; (b) allowing testimony from INS agent McDonald as to a
    widespread smuggling problem; (c) allowing the jury to be informed of the grand
    jury indictment; (d) using a financial affidavit, in which Mr. Favela stated that he
    -20-
    was indigent, to impeach his statements about having a legitimate business; (e)
    refusing to allow him to use a videotape that concerned the relative speed of the
    vehicles at the time of the traffic stop.
    We review a district court’s rulings on evidentiary matters for abuse of
    discretion. United States v. Weller, 
    238 F.3d 1215
    , 1220 (10th Cir. 2001). “In
    order to reverse a district court judgment on account of an evidentiary ruling, [an
    appellant] must make a clear showing [he] suffered prejudice, and the ruling was
    inconsistent with substantial justice or affected h[is] substantial rights.” Coletti v.
    Cudd Pressure Control, 
    165 F.3d 767
    , 773 (10th Cir. 1999) (internal quotation
    marks omitted).
    Upon review of the record, we discern no grounds for reversal. As the
    government notes, many of Mr. Favela’s arguments are conclusory and provide no
    citations to the record and no explication of the legal authority supporting the
    claims of error. In any event, Mr. Favela has not established that any of these
    rulings was “inconsistent with substantial justice or affected h[is] substantial
    rights.” 
    Id.
     (internal quotation marks omitted). 6
    6
    We do view one evidentiary issue with some concern: the government’s
    introduction of a financial affidavit (signed by Mr. Favela in order to have
    counsel appointed for him). The government introduced this affidavit in order to
    rebut Mr. Favela’s contention that he ran a legitimate business. The district court
    ruled that the affidavit was part of the court record and could be used for
    impeachment. See Rec. vol. VI, at 807.
    (continued...)
    -21-
    F. Cumulative Error
    Finally, Mr. Favela argues that the cumulative errors of the government and
    the trial judge warrant a new trial. “[C]umulative-error analysis should evaluate
    only the effect of matters determined to be error, not the cumulative effect of
    non-errors.”   United States v. Rivera , 
    900 F.2d 1462
    , 1471 (10th Cir.1990).
    Because Mr. Favela has not shown any individual errors, he cannot prevail on his
    claim of cumulative error.
    6
    (...continued)
    In United States v. Hardwell, 
    80 F.3d 1471
    , 1483 (10th Cir. 1996), this
    court held that the government violated the defendant’s Fifth Amendment right
    against self incrimination by offering, as part of its case in chief, statements made
    the defendant to establish eligibility for appointed counsel.
    In this case, the government attempts to distinguish Hardwell by arguing
    that it used the affidavit only to impeach witnesses who testified that Mr. Favela
    had a legitimate transportation business. For several reasons, we need not decide
    in this case whether the government’s attempt to distinguish Hardwell is
    persuasive.
    First, Hardwell involves a Fifth Amendment right. In his opening brief,
    Mr. Favela argues that the admission of the financial affidavit was an evidentiary
    error, but he does not raise a Fifth Amendment claim. Thus, we need not consider
    the argument that the admission of the affidavit violated his Fifth Amendment
    rights. See United States v. Murray, 
    82 F.3d 361
    , 363 n. 3 (10th Cir. 1996)
    (declining to consider arguments raised for the first time in a reply brief).
    Moreover, any Fifth Amendment violation arising out of the introduction
    of the financial affidavit is still subject to review for harmless error. See
    Hardwell, 
    80 F.3d at 1483
     (noting that the financial affidavit had little relevance
    to one of the charges and therefore affirming that conviction). Here, the
    government presented other evidence to rebut Mr. Favela’s contention that he ran
    a legitimate business. Thus, the admission of the affidavit was harmless.

    III. CONCLUSION
    For the reasons set forth above, we AFFIRM Mr. Favela’s convictions and
    sentences.
