    OPINION OF THE COURT
    GARTH, Circuit Judge:
    We have granted en banc review to resolve a conflict in
    our court's jurisprudence that has surfaced following the
    publication of United States v. Cohen, 
    171 F.3d 796
    (3d Cir.
    1999), United States v. Gaev, 
    24 F.3d 473
    (3d Cir. 1994),
    and United States v. Gambino, 
    926 F.2d 1335
    (3d Cir.
    1991), on the one hand, and United States v. Thomas, 
    998 F.2d 1202
    (3d Cir. 1993), on the other.1 In the instant
    matter, the District Court permitted the government,
    pursuant to Federal Rule of Evidence ("Federal Rule") 403,
    to introduce both the plea agreements and guilty pleas of
    two witnesses notwithstanding a representation by defense
    counsel that they would not challenge the credibility of
    such witnesses. The jury convicted all three defendants on
    a sole count of mail fraud. The panel majority reversed. We
    granted the government's petition for rehearing and vacated
    the panel decision.2
    We will now affirm the convictions entered against
    defendants Universal Rehabilitation Services (PA), Inc., and
    Richard Lukesh.
    I
    Universal Rehabilitation Services (PA), Inc. ("Universal") is
    engaged in the business of providing various rehabilitative
    services, especially speech therapy, to elderly Medicare
    patients living in nursing homes. Universal would enter into
    _________________________________________________________________

    guilty plea and/or plea agreement include the following: Government of
    the Virgin Islands v. Mujahid, 
    990 F.2d 111
    (3d Cir. 1993); United States
    v. Werme, 
    979 F.2d 108
    (3d Cir. 1991); United States v. Inadi,

    623 F.2d 307

    1980); United States v. Gullo, 
    502 F.2d 759
    (3d Cir. 1974); United States
    v. Toner, 
    173 F.2d 140
    (3d Cir. 1949).
    2. The government did not petition for rehearing with respect to the
    original panel's disposition of Attila Horvath's appeal. See infra n.8.
    3
    contracts with several local nursing homes, and would
    thereafter send its speech therapists to treat patients on
    site. Rather than submit its bills directly to Medicare,
    Universal employed Independence Blue Cross ("IBC") as an
    intermediary processor. Under this arrangement, Universal
    would submit its claims to IBC, which would process and
    organize such claims before sending them to Medicare.
    Both federal law and the regulations promulgated by the
    Secretary of Health & Human Services authorize the
    Medicare program to pay only those claims that are deemed
    to be medically reasonable and necessary. In determining
    whether this criteria have been met with specific reference
    to speech therapy services, the Medicare program generally
    looks to four separate criteria: (1) the therapy must be safe
    and effective for treating the patient's condition; (2) the
    services provided must be sufficiently complex insofar as
    only a certified speech pathologist can provide such
    services; (3) if restorative treatment were ordered, the
    pathologist must expect that the services would improve
    the patient's condition significantly in a reasonable amount
    of time; and (4) the frequency and duration of the services
    must bear a reasonable and necessary relation to the
    patient's condition. In this criminal matter, the government
    contends that both Universal and its representatives
    intentionally altered the claims it submitted to IBC in order
    to meet these criteria.
    Pursuant to a physician's orders, a Universal therapist
    would evaluate a patient's needs in order to determine
    initially whether treatment was necessary, and if so,
    propose a program of treatment. Once a physician approved
    the evaluation, this evaluation became a vitally important
    document for Medicare purposes insofar as it provided an
    assessment that the treatment was medically necessary for
    the patient. Indeed, Medicare reviewers specifically
    considered the evaluation in rendering reimbursement
    decisions.
    Once treatment of a particular patient commences,
    Medicare requires that a physician certify each thirty days
    that continued treatment was medically necessary. Further,
    Medicare will only pay for such continued treatment so long
    as the patient is progressing towards the goals referenced
    4
    in the initial evaluation, and as such, Universal therapists
    would write notes concerning the patient's progress.
    Universal would meet the thirty-day recertification
    requirement by having a physician sign a Medical
    Information Form ("MIF ") that contained a summary of the
    previous thirty days of treatment and the prescribed course
    of treatment for the thirty days to come.
    Universal would submit its Medicare claims to IBC
    electronically for IBC's review. According to Universal, IBC's
    requirements for the proper processing of its claims were
    elaborate, detailed, and extremely difficult with which to
    comply. For this reason, Universal and IBC often differed as
    to the proper interpretation of the Medicare regulations,
    and, indeed, the ultimate decision as to whether Medicare
    would reimburse a particular claim. Pursuant to a random
    auditing system, IBC ultimately requested Universal to
    provide documentation in support of certain claims that
    Universal had submitted. Irregularities in this
    documentation led IBC to investigate further, an
    investigation that uncovered the very "rewriting" scheme
    that is at issue in this criminal matter.
    The government alleges that between the summer of
    1988 and September 21, 1991, Universal and its
    representatives altered and rewrote certain Medicare claims
    in order to ensure that the Medicare program would
    reimburse such claims. Universal admits that this
    occurred, but claims that such rewriting had two forms: (1)
    honestly inserting omitted information so as to comply with
    Medicare regulations; and (2) altering initial evaluations,
    medical information forms, and progress certifications so as
    to reflect either the need for medical treatment or to certify
    that the patient was progressing because of treatment
    already provided.
    As for this latter form of rewriting, the government
    contends that initial evaluations were altered so as to
    provide the "appearance" that speech therapy was medically
    necessary for the patient, medical information forms were
    made to appear as if a physician actually had reviewed the
    patient's progress and recommended that the speech
    therapy continue, and finally, the therapists' personal
    progress notes concerning the patient were modified to
    5
    provide the appearance that the patient was improving. In
    order to obtain the required physician's signature,
    Universal and its representatives would photocopy the
    physician's signature on the initial form and paste this
    photocopy on the altered form. Only after the rewriting
    occurred would the claims be submitted to IBC for review.
    All of these efforts, of course, were intended to increase the
    likelihood that Medicare would reimburse Universal for the
    speech therapy services Universal claimed to have rendered.3
    On March 31, 1995, a federal grand jury indicted
    appellants Universal, Universal's Vice-President and
    Director of Finance, Attila Horvath ("Horvath"), Universal's
    Director of Operations, Richard Lukesh ("Lukesh"), and
    three other defendants4 on seventeen counts of mail fraud,
    in violation of 18 U.S.C. S 1341, and twenty-one counts of
    false claims, in violation of 18 U.S.C. S 287. Prior to trial,
    Julia Blum Bonjo ("Bonjo") and Penny Martin ("Martin")
    pled guilty to a sole count of mail fraud in connection with
    the scheme described above.5 Universal, Horvath, and
    Lukesh, also prior to trial, filed motions in limine with the
    District Court, attempting to prevent the government,
    pursuant to Federal Rule 403, from introducing such guilty
    pleas and plea agreements into evidence. At the same time,
    Universal, Horvath, and Lukesh each represented that they
    would not affirmatively challenge the credibility of either
    Bonjo or Martin during cross-examination.6 The District
    _________________________________________________________________
    3. Fraud has been pervasive in connection with Medicare
    reimbursement. See Georgia Court, Keeping an Eye on Medicare Fraud,
    Cincinnati Post, Dec. 16, 1999, at 4C ("The Office of the Inspector
    General at Health and Human Services estimated that $12.6 billion [of
    $176.1 billion in Medicare payments were] improper."); Medicare
    Contractors Aren't Pursuing Fraud, Audit Shows, USA Today, Dec. 2,
    1998, at A1.
    4. The other defendants were Vicki Meitus, Mary Mongoven Conroy, and
    Julia Blum Bonjo.
    5. As stated above, Bonjo had been indicted with Universal, Horvath, and
    Lukesh -- the appellants in this appeal. Martin, however, pled guilty to
    a separate information filed by the government.
    6. Specifically, Lukesh's Motion in Limine stated, in pertinent part, that
    "Defendant asserts that at the trial of this action he will not raise the
    guilty pleas/plea agreements on cross-examination nor seek to raise any
    inference on which the accomplices [sic] pleas of guilty would be
    admissible to rebut." App. at 79.
    6
    Court held extensive oral argument on this issue, and
    reserved its ruling until after the trial had commenced and
    the government was prepared to call Bonjo as a witness.
    Citing to our opinion in United States v. Gaev , 
    24 F.3d 473
    (3d Cir. 1994), the District Court then denied the motions
    in limine and permitted the government to introduce both
    Bonjo and Martin's guilty pleas and plea agreements as
    part of its principal case. In particular, the District Court
    stated that
    if [Bonjo and Martin] testify the jury is going to
    certainly wonder whether or not they have been
    charged. It's going to wonder perhaps what they have
    been promised by the prosecutor if anything and what
    they may be getting in return for their testimony.
    I think in weighing all of those factors with the possible
    prejudice that I am going to allow the Government to
    bring out the fact of the guilty plea and the fact of the
    guilty plea agreement.
    App. at 1768.
    After the government had introduced the evidence of
    Bonjo's plea and concomitant plea agreement, the District
    Court immediately instructed the jury as follows:
    Members of the jury, you've just heard .   . . evidence
    that this witness has plead [sic] guilty   to a charge of
    mail fraud and which involved matters of   some of the
    things that she has testified to here in   this trial.
    I caution you that although you may consider this
    evidence, that is the evidence that she has entered a
    plea of guilty in assessing the credibility and the
    testimony of this witness, you should give it such
    weight as you feel it deserves.
    You may not consider the evidence that she has entered
    a plea of guilty against any defendant, any in this case,
    nor may any inference be drawn against any defendant
    on trial by reason of this witness's plea of guilty.
    App. at 1966-67 (emphasis added). The District Court
    provided a similarly detailed instruction after the
    government elicited testimony concerning Martin's plea
    7
    agreement. App. at 2863-64. Finally, during its charge to
    the jury after the trial, the District Court instructed as
    follows:
    Julia Blum Bonjo and Penny Martin entered into plea
    agreements with the Government. Such plea
    agreements are expressly approved as lawful and
    proper by the United States Supreme Court and are
    appropriate, are proper. Each witness' decision to plead
    guilty is a personal decision about her own guilt. You
    may not consider this evidence against the defendant
    on trial nor may you draw any conclusions or
    inferences of any kind about the guilt of the defendants
    on trial from the fact that a prosecution witness pled
    guilty to similar charges.
    The testimony of such witnesses, as I indicated, should
    be scrutinized with caution and give it the weight that
    you think it should be given under all of the
    circumstances.
    And I indicated to you during the trial that the fact
    that they entered pleas of guilty could not be
    considered by you in determining the guilt or
    innocence of any of the people on trial here. The only
    reason the plea and the plea agreement were brought
    out was so that you would know all of the
    circumstances surrounding the entry of the plea, you'd
    know the terms under which the plea was entered and
    you could judge for yourselves whether the witness in
    the trial is testifying truthfully or whether the witness
    has a motive to embellish testimony or vary from the
    truth.
    That is the only basis or the only reason why the plea
    and the plea agreement were admitted.
    App. at 4829-30.
    After deliberation, the jury found Universal, Horvath, and
    Lukesh guilty on count one of the indictment, which
    specifically alleged that Universal had engaged in mail
    fraud when IBC mailed a check to Universal representing a
    claim for treatment provided to one of its patients, Mildred
    Hynes, between February 15, 1989, and February 28,
    8
    1989. The jury, however, also found Universal, Horvath,
    and Lukesh not guilty on the remaining thirty-eight counts
    of the indictment. All three defendants then moved for a
    judgment of acquittal pursuant to Federal Rule of Criminal
    Procedure 29, arguing that the government had introduced
    insufficient evidence to support the jury's verdict. On May
    31, 1996, the District Court denied this motion and
    proceeded to sentencing.7 On May 19, 1997, the District
    Court sentenced Universal to a fine of $25,000, Horvath to
    a period of three years probation, a fine of $10,000, and
    $705.20 in restitution, and Lukesh to three years of
    probation, a fine of $15,000, and $705.20 in restitution.
    Universal, Horvath, and Lukesh appealed the judgment of
    conviction and sentence to this Court, arguing that the
    District Court abused its discretion in admitting the guilty
    pleas of Bonjo and Martin, and in denying their post-trial
    motions for judgments of acquittal on sufficiency of
    evidence grounds. In particular, the defendants argued that
    the fact that the jury had convicted them of the same count
    to which Bonjo and Martin had pled guilty -- and had then
    acquitted them of the remaining thirty-eight counts of the
    indictment -- proved that the admission of Bonjo and
    Martin's plea agreements and guilty pleas had a clear
    prejudicial effect.
    The government cross-appealed, arguing that the District
    Court erred in sentencing Horvath and Lukesh by failing to
    consider the loss stemming from the fraud alleged in the
    other thirty-eight counts of the indictment on which the
    jury acquitted Universal, Horvath, and Lukesh --"relevant
    conduct" pursuant to sections 1B1.3 and 2F1.1 of the
    United States Sentencing Guidelines -- and in failing to
    provide required findings of fact with regard to the
    sentences the District Court imposed. The government also
    answered the defendants' argument concerning the guilty
    _________________________________________________________________
    7. The District Court's May 31, 1996 opinion also revisited the issue
    presently before the en banc court; namely, whether it was an abuse of
    discretion to allow the introduction of Bonjo and Martin's guilty pleas.
    The court concluded that it had not erred, reiterating its concern over
    selective prosecution and that the witnesses' testimony would assist the
    jury in assessing credibility.
    9
    plea issue by arguing that a party cannot attack a District
    Court's evidentiary ruling made prior to or during a trial by
    referencing a jury's ultimate verdict. The government
    claimed that such hindsight could not be used to measure
    the District Court's exercise of discretion.
    In an opinion filed on February 11, 1999, the panel, one
    judge dissenting, reversed. More specifically, the panel held
    that there was insufficient evidence to convict Horvath of
    mail fraud, but that the government had introduced
    sufficient evidence to support the convictions of both
    Universal and Lukesh. As such, the panel majority
    remanded to the District Court to enter a judgment of
    acquittal for Horvath.
    The panel majority also held that the District Court had
    abused its discretion in allowing the government to
    introduce evidence of Bonjo and Martin's guilty pleas, and
    as a result, ordered the District Court to hold a new trial
    concerning the charges levied against Universal and
    Lukesh. Because of this, the panel majority did not reach
    the sentencing issues presented in the government's cross-
    appeal.
    On April 15, 1999, the full court granted the
    government's petition for rehearing en banc, and vacated
    the panel's opinion and judgment.8 See United States v.
    Universal Rehabilitation Servs. (PA), Inc., Nos. 97-1412, 97-
    1414, 97-1468, 
    1999 WL 239513
    , at *1 (3d Cir. Apr. 15,
    1999). Our order focused rehearing on the District Court's
    denial of the defendants' motions in limine, which sought to
    prevent the government from introducing Bonjo and
    Martin's guilty pleas. See id.; see also United States v.
    Universal Rehabilitation Servs. (PA), Inc., 
    173 F.3d 914
    , 915
    (3d Cir. 1999) (directing parties to "file supplemental
    _________________________________________________________________
    8. Our en banc order only vacated the panel opinion and judgment
    insofar as it concerned Universal and Lukesh. As such, the panel's
    holding that the government failed to present sufficient evidence to
    justify the jury's conviction of Horvath, and that the District Court
    therefore erred in failing to order a judgment of acquittal on Horvath's
    behalf remains unaffected. Because our holding today revives the need
    to address the government's cross-appeal as to the sentence the District
    Court imposed against Lukesh, we discuss that issue in text infra.
    10
    memoranda . . . set[ting] forth what factors should be
    considered by the District Court in ruling on the
    admissibility of a testifying co-conspirator's guilty plea"). We
    now affirm the convictions of Universal and Lukesh entered
    by the District Court.
    II
    The District Court exercised subject matter jurisdiction
    pursuant to 18 U.S.C. S 3231. We possess appellate
    jurisdiction over Universal and Lukesh's arguments of error
    pursuant to the final order doctrine of 28 U.S.C.S 1291.
    III
    A
    We have previously held that the admission of a witness's
    guilty plea and/or plea agreement9 is governed by Federal
    Rule 403, see, e.g., United States v. Gaev, 
    24 F.3d 473
    , 478
    (3d Cir. 1994), and as such, the rule itself provides an
    appropriate starting point for our analysis. Federal Rule
    403 provides:
    _________________________________________________________________
    9. Universal and Lukesh claim that the terms"plea" and "plea
    agreement" should not be utilized interchangeably and that the District
    Court's admission of Bonjo and Martin's plea agreements was an
    especially grave abuse of discretion. Although we agree that the terms
    are not synonymous, we believe that the distinction that Universal and
    Lukesh attempt to draw is one without a difference as it relates to the
    Federal Rule 403 analysis. Once one accepts the premise that a
    witness's guilty plea has probative value, see text infra, especially with
    respect to the witness's credibility, the introduction of the terms of the
    plea agreement becomes a necessary complement to disclose to the jury
    that the witness has not been promised a "sweetheart deal" in exchange
    for the testimony. See United States v. Pierce , 
    959 F.2d 1297
    , 1304 (5th
    Cir. 1992). Further, Universal and Lukesh have failed to identify any
    prejudicial effect that could flow from the introduction of the terms of
    the
    witnesses' plea agreements once the pleas themselves are accepted into
    evidence. As such, for purposes of our analysis, the District Court's
    admission of Bonjo and Martin's pleas and plea agreements are treated
    equally.
    11
    Although relevant, evidence may be excluded if its
    probative value is substantially outweighed by the
    danger of unfair prejudice, confusion of the issues, or
    misleading the jury, or by considerations of undue
    delay, waste of time, or needless presentation of
    cumulative evidence.
    FED. R. EVID. 403. As the text of the rule indicates, evidence
    that is otherwise relevant and admissible may only be
    excluded if the probative value of the evidence is
    substantially outweighed by its prejudicial effect. For this
    reason, a number of courts have held that Federal Rule 403
    creates a presumption of admissibility, and that district
    courts may utilize the rule only rarely to cause the
    exclusion of evidence. See, e.g., United States v. Morris, 
    79 F.3d 409
    , 412 (5th Cir. 1996); Hendrix v. Raybestos-
    Manhattan, Inc., 
    776 F.2d 1492
    , 1502 (11th Cir. 1985). As
    one leading treatise states, "[i]f there is doubt about the
    existence of unfair prejudice . . . it is generally better
    practice to admit the evidence, taking necessary
    precautions by way of contemporaneous instructions to the
    jury followed by additional admonitions in the charge." 2
    Weinstein's Federal Evidence, S 403.02[2][c], at 403-16
    (Joseph M. McLaughlin ed., 1999); see also Glen
    Weissenberger, Federal Evidence, S 403.2, at 87 (3d ed.
    1998) ("Rule 403 favors a presumption of admissibility.").
    We have also held that because the trial judge is present
    in the courtroom as the challenged evidence is offered, and
    is therefore "in the best position to assess the extent of the
    prejudice caused a party," the trial judge must"be given a
    very substantial discretion in ``balancing' probative value on
    the one hand and ``unfair prejudice' on the other." United
    States v. Long, 
    574 F.2d 761
    , 767 (3d Cir. 1978) (emphasis
    added); cf. General Electric Co. v. Joiner, 
    522 U.S. 136
    , 143
    (1997) (holding, in the context of expert testimony, that
    "deference . . . is the hallmark of abuse of discretion
    review"). For this reason, we review a district court's
    balancing analysis pursuant to Federal Rule 403 for an
    abuse of discretion, see In re Paoli R.R. Yard PCB Litig., 
    113 F.3d 444
    , 453 (3d Cir. 1997), and accord great deference to
    the District Court's ultimate decision.
    12
    A district court's decision, therefore, cannot be reversed
    merely because we, as members of a reviewing court,
    possess a different view concerning the probative value or
    prejudicial effect of the challenged evidence. See 
    Long, 574 F.2d at 767
    . In order to justify reversal, a district court's
    analysis and resulting conclusion must be "arbitrary or
    irrational."10 
    Paoli, 113 F.3d at 453
    . Indeed, "[i]f judicial
    self-restraint is ever desirable, it is when a [Federal] Rule
    403 analysis of a trial court is reviewed by an appellate
    tribunal." 
    Long, 574 F.2d at 767
    . With this in mind, we
    turn now to the application of these principles to the
    District Court's admission of both Bonjo and Martin's guilty
    pleas and the plea agreements that they executed with the
    government.
    B
    Any analysis pursuant to Federal Rule 403 must begin
    with a determination as to whether the evidence has
    probative value. It is well-settled that evidence of a
    testifying witness's guilty plea or plea agreement may be
    introduced for probative, and therefore permissible,
    purposes. As this Court has identified on numerous
    occasions, such purposes include: (1) to allow the jury
    accurately to assess the credibility of the witness; (2) to
    eliminate any concern that the jury may harbor concerning
    whether the government has selectively prosecuted the
    defendant; and (3) to explain how the witness hasfirst-
    hand knowledge concerning the events about which he/she
    is testifying. See 
    Gaev, 24 F.3d at 476
    ; United States v.
    Gambino, 
    926 F.2d 1355
    , 1363 (3d Cir. 1991); United
    States v. Werme, 
    939 F.2d 109
    , 113 (3d Cir. 1991); United
    States v. Inadi, 
    790 F.2d 383
    , 384 n.2 (3d Cir. 1986); see
    _________________________________________________________________
    10. As with other instances in which a district court exercises its
    discretion, we also have held that when a district court issues a ruling
    pursuant to Federal Rule 403, it must specifically indicate its rationale.
    See 
    Paoli, 113 F.3d at 453
    (quoting United States v. Murray, 
    103 F.3d 310
    , 318 (3d Cir. 1997)). In the present matter, there is no dispute that
    the District Court more than satisfied this requirement, as it expressly
    stated at the time of its ruling that it believed Bonjo and Martin's
    guilty
    pleas would assist the jury in assessing credibility and alleviate any
    concern the jury held over selective prosecution. App. at 1768.
    13
    also United States v. Thomas, 
    998 F.2d 1202
    , 1208 (3d Cir.
    1993) (Rosenn, J., dissenting).
    As we held in Werme, "[t]he most frequent purpose for
    introducing such evidence is to bring to the jury's attention
    facts bearing upon a witness's credibility." 
    Werme, 939 F.2d at 114
    (citing 
    Gambino, 926 F.2d at 1363
    ). Universal and
    Lukesh, however, argue that witness credibility ceased to
    be a proper purpose for the admission of Bonjo and
    Martin's guilty pleas once they promised, through their
    motions in limine, not to attack Bonjo and Martin's
    credibility. Jurors are instructed, however, in almost all
    cases, that they are to determine the credibility of all
    witnesses who testify. Indeed, they are so instructed even
    in the absence of an affirmative challenge to witness
    credibility. See 1A Kevin F. O'Malley et al., Federal Jury
    Practice & Instructions (Criminal), S 15.01, at 350 (5th ed.
    2000) ("You, as jurors, are the sole and exclusive judges of
    the credibility of each of the witnesses called to testify in
    this case and only you determine the importance or the
    weight that their testimony deserves.").11 We addressed this
    argument in Gaev:
    When a co-conspirator testifies he took part in the
    crime with which the defendant is charged, his
    credibility will automatically be implicated. Questions
    will arise in the minds of the jurors whether the co-
    conspirator is being prosecuted, why he is testifying,
    and what he may be getting in return. If jurors know
    the terms of the plea agreement, these questions will
    be set to rest and they will be able to evaluate the
    declarant's motives and credibility. . . . [A]n attack is
    not always necessary.
    
    Gaev, 24 F.3d at 477
    . Our sister circuits concur. See, e.g.,
    United States v. Pennington, 
    168 F.3d 1060
    , 1067 (8th Cir.
    1999); United States v. Maliszewski, 
    161 F.3d 992
    , 1003-04
    (6th Cir. 1998); United States v. Sanders, 
    95 F.3d 449
    , 454
    (6th Cir. 1996). As such, we are satisfied that the
    _________________________________________________________________
    11. The   District Court similarly charged the jury in the present matter.
    App. at   4825 ("[Y]ou are the judges of the facts and therefore in the
    process   you are also the sole judges of the credibility of the witnesses
    and the   weight their testimony deserves.").
    14
    government may seek to introduce a witness's guilty plea
    and/or plea agreement even in the absence of a challenge
    to the witness's credibility.
    Universal and Lukesh argue, however, that the Supreme
    Court's recent opinion in Old Chief v. United States, 
    519 U.S. 172
    (1997), provides support for their argument. In
    Old Chief, the defendant was charged with violating a
    federal law, 18 U.S.C. S 922(g)(1), which prohibits an
    individual previously convicted of a felony from possessing
    a firearm. See 
    id. at 174.
    Because the government was
    required, as a part of its prima facie case, to prove that the
    defendant had previously been convicted of a felony, it
    sought to present evidence of such a conviction. See 
    id. at 175.
    Concerned that evidence of the previous crime would
    adversely influence the jury towards his defense, the
    defendant sought to prevent the government from
    introducing such evidence by stipulating that he had
    previously been convicted of a felony. See 
    id. The District
    Court refused to compel the government to stipulate, and
    allowed the government to introduce evidence of the prior
    crime. See 
    id. The Court
    of Appeals affirmed the conviction,
    finding that regardless of the defendant's offer to stipulate,
    the government was entitled to prove the prior crime
    through the introduction of probative evidence. See 
    id. at 177.
    The Supreme Court reversed, holding that the District
    Court had abused the discretion with which it was vested
    under Federal Rule 403. See 
    id. at 178.
    Although the Court
    reaffirmed the general principle that the government "is
    entitled to prove its case by evidence of its own choice," it
    held that a defendant may avoid the introduction of
    potentially prejudicial evidence by presenting the
    government with an equally probative evidentiary
    alternative. 
    Id. at 186.
    Finally, the Court held that a
    stipulation that the defendant had been convicted of a
    crime within the purview of the federal firearms law was of
    equal probative value to the government's proffered
    evidence, and as such, the District Court had abused its
    discretion. See 
    id. Universal and
    Lukesh argue that they, similar to the
    defendant in Old Chief, presented the District Court with an
    15
    alternative that lacked the prejudicial effect of the
    government's proffered evidence -- a representation that
    they would refrain from any affirmative challenge to the
    credibility of either Bonjo or Martin. This alternative,
    however, presented the District Court with a much different
    scenario than that which faced the district court in Old
    Chief.12 First, the defendant in Old Chief offered to stipulate
    to an element of the offense, whereas Universal and Lukesh
    simply offered not to render any affirmative challenge to
    Bonjo or Martin's credibility. Second, and of greater
    importance, the Court's holding in Old Chief was expressly
    premised on the Court's belief that the defense's offer to
    stipulate to the prior conviction and the government's offer
    to introduce evidence of the same were equally probative.
    See 
    id. at 191.
    In this appeal, however, Universal and
    Lukesh's offer to refrain from affirmatively challenging
    Bonjo or Martin's credibility did not, and could not, carry
    the same probative value on the issue of witness credibility
    as the introduction of Bonjo and Martin's guilty pleas.
    Even if we were inclined to accept Universal and Lukesh's
    arguments concerning credibility, however, we have
    identified other purposes for which the government sought
    to introduce Bonjo and Martin's pleas and/or plea
    agreements. In particular, the pleas were admissible to
    counteract the possibility that the jury might believe that
    Universal and Lukesh were being selectively prosecuted.
    See, e.g., 
    Gaev, 24 F.3d at 479
    . In other words, once Bonjo
    and Martin testified concerning their participation in the
    events for which Universal and Lukesh had been indicted,
    the jury reasonably might conclude that the government
    was attempting to single out Universal and Lukesh for
    prosecution.
    Finally, courts have also held that a witness's guilty plea
    is admissible to explain why the witness possesses
    firsthand knowledge concerning the events to which he or
    she is testifying. See, e.g., United States v. Halbert, 
    640 F.2d 1000
    , 1005 (9th Cir. 1981). Although one might view
    this as a corollary to the credibility rationale, members of
    _________________________________________________________________
    12. Universal and Lukesh concede that their analogy to Old Chief is not
    perfect. See Appellants' Supplemental Memorandum, at 19.
    16
    the jury may still question whether the witness's testimony
    is worthy of belief. The fact that the witness has pled guilty
    to an offense concerning the very events that required his
    or her testimony makes it that much more likely that the
    testimony is truthful and reliable, as an individual typically
    does not plead guilty to an offense in the absence of
    culpability. As such, the government was entitled to
    introduce Bonjo and Martin's pleas in order to answer any
    question the jury might have concerning how Bonjo and
    Martin possessed knowledge of the events and actions
    about which they testified.
    As a result, we hold that evidence of Bonjo and Martin's
    guilty pleas and their concomitant plea agreements were
    probative in terms of Federal Rule 403, despite Universal
    and Lukesh's representation not to challenge Bonjo and
    Martin's credibility.13
    _________________________________________________________________
    13. Section IV of Judge Roth's dissent advances an argument that not
    even Universal and Lukesh have asserted. Her dissent charges that we
    have offended both subsections (a) and (b) of Federal Rule 608 by
    holding that the District Court properly admitted the guilty pleas of
    Bonjo and Martin.
    Federal Rule 608 prohibits the introduction of either "character
    evidence" or "specific instances of conduct" proved by extrinsic evidence
    in order to support a witness's credibility. The dissent claims that Bonjo
    and Martin's guilty pleas could be considered both "character evidence"
    and "specific conduct," and because the government introduced the
    pleas -- at least in part -- to support Bonjo and Martin's credibility,
    Federal Rule 608 bars their admission.
    The short answer to these arguments is that at no time did Universal
    or Lukesh ever raise Federal Rule 608 as a bar to the admission of Bonjo
    and Martin's pleas. Universal and Lukesh did not lodge an objection on
    this basis at any point during the District Court proceedings, and did
    not raise the issue before either the panel reviewing the District Court's
    ruling or this en banc court. As a result, not only was this theory
    deemed irrelevant by Universal and Lukesh, but by not raising it, they
    have waived any benefit they may have derived from such an argument.
    See FED. R. EVID. 103(a)(1); United States v. Gibbs, 
    739 F.2d 838
    , 849 (3d
    Cir. 1984) (en banc). Moreover, Federal Rule 608(a) applies only to
    opinion and reputation evidence that is probative of one's character, and
    it is beyond dispute that the guilty pleas do not fall into either of
    these
    narrow categories. Finally, courts have interpreted Federal Rule 608(b)'s
    17
    C
    We have repeatedly held that the government may
    introduce neither a witness's guilty plea nor his or her
    concomitant plea agreement as substantive evidence of a
    defendant's guilt. See, e.g., 
    Gaev, 24 F.3d at 476
    ; 
    Gambino, 926 F.2d at 1363
    . We discussed the rationale for this rule
    at length in United States v. Toner, 
    173 F.2d 140
    (3d Cir.
    1949):
    The foundation of the countervailing policy is the right
    of every defendant to stand or fall with the proof of the
    charge made against him, not against somebody else.
    The defendant had a right to have his guilt or
    innocence determined by the evidence presented
    against him, not by what has happened with regard to
    a criminal prosecution against someone else.
    
    Id. at 142,
    quoted in Bisaccia v. Attorney General, 
    623 F.2d 307
    , 312 (3d Cir. 1980). As such, the bald introduction of
    a witness's guilty plea concerning facts or events similar to
    that for which the defendant is on trial could have the
    prejudicial effect of suggesting to the trier of fact that the
    defendant should be found guilty merely because of the
    witness's guilty plea.
    Nonetheless, we have also consistently held that this
    prejudicial effect is typically cured through a curative
    instruction to the jury. See, e.g., 
    Mujahid, 990 F.2d at 116
    ;
    
    Werme, 939 F.2d at 113
    .14 Our sister circuits, once again,
    _________________________________________________________________
    bar on "specific instances of conduct" to prohibit the introduction of
    conduct only if it is being used to either attack or bolster the witness's
    character (i.e., one's general disposition, see United States v. Doe, 
    149 F.3d 634
    (7th Cir. 1998)) for truthfulness. See, e.g., United States v.
    Pope, 
    132 F.3d 684
    , 688 (11th Cir. 1998). Because the government did
    not introduce Bonjo and Martin's guilty pleas to prove that Bonjo and
    Martin generally spoke and/or acted truthfully, Federal Rule 608(b) is
    inapposite.
    14. Universal and Lukesh argue that we should revisit our rule that any
    prejudicial effect inherent in the introduction of a witness's guilty plea
    and/or plea agreement can be ameliorated through the use of a limiting
    instruction, arguing, inter alia, that juries cannot comprehend such
    18
    concur in this understanding. See, e.g., United States v.
    Prawl, 
    168 F.3d 622
    (2d Cir. 1999); United States v. Tse,
    
    135 F.3d 200
    , 207 (1st Cir. 1998); 
    Sanders, 95 F.3d at 454
    ;
    see also 
    Pierce, 959 F.2d at 1304
    . The jury in such cases
    should be instructed that it may not consider the guilty
    plea and/or plea agreement as evidence that the defendant
    is guilty of the offenses with which he/she is charged, but
    rather that such evidence is offered only to allow the jury
    to assess the witness's credibility, to eliminate any concern
    that the defendant has been singled out for prosecution, or
    to explain how the witness possessed detailed first-hand
    knowledge regarding the events about which he or she
    testifies.
    As recounted above, the District Court provided such an
    instruction at three separate occasions during the trial:
    after Bonjo testified, after Martin testified, and at the end of
    the trial when the District Court charged the jury. See 
    text supra
    at pp. 7-8. The District Court's instructions,
    therefore, served to cure any prejudicial effect that might
    flow from the introduction of the guilty plea and/or plea
    agreement of a witness such as Bonjo or Martin.
    Universal and Lukesh, however, argue that our previous
    jurisprudence in this area suggests that limiting
    instructions are not sufficient to neutralize such prejudicial
    effect in situations where the defendant is charged with
    conspiracy and the witness whose guilty plea and/or plea
    agreement the government introduces is the individual with
    whom the defendant has been alleged to conspire. The
    genesis of this concern emanates from United States v.
    Gullo, 
    502 F.2d 759
    (3d Cir. 1974), in which we stated:
    _________________________________________________________________
    limiting instructions. We are not persuaded by their arguments. See FED.
    R. EVID. 105 ("When evidence which is admissible as to one party or for
    one purpose but not admissible as to another party or for another
    purpose is admitted, the court, upon request, shall restrict the evidence
    to its proper scope and instruct the jury accordingly."); Spencer v.
    Texas,
    
    365 U.S. 554
    , 562-63 (1967) ("[T]his type of prejudicial effect is
    acknowledged to inhere in criminal practice, but it is justified on the
    grounds that . . . the jury is expected to follow instructions in limiting
    this evidence to its proper function.").
    19
    The guilty plea to a conspiracy charge carries with it
    more potential harm to the defendant on trial because
    the crime by definition requires the participation of
    another. The jury could not fail to appreciate the
    significance of this and would realize . . . that"it takes
    two to tango." A plea by a co-conspirator thus presents
    a unique situation which may require the courts to
    scrutinize more closely the purported remedial effect of
    instructions.
    
    Id. at 761
    (footnote omitted). The Gullo panel stopped short
    of recognizing, however, any "distinction between cases
    where the plea is to a substantive, rather than to a
    conspiracy count." 
    Id. In the
    instant matter, it is significant
    that both Bonjo and Martin did not plead guilty to
    conspiracy charges, but rather pled guilty to substantive
    counts of mail fraud. App. at 1966, 2863. In any event, we
    held in Gaev that the fact that the witness had pled guilty
    to a conspiracy charge was merely another factor that a
    district court must weigh in engaging in the Federal Rule
    403 analysis. See 
    Gaev, 24 F.3d at 478-79
    .
    Accordingly, we hold that the detailed limiting
    instructions provided by the District Court cured the
    prejudicial effect, if any, flowing from the introduction of
    Bonjo and Martin's guilty pleas and plea agreements.
    D
    As we stated above, we cannot reverse a District Court's
    conclusion under Federal Rule 403 unless such a
    conclusion is held to be an abuse of discretion, which we
    have defined as "arbitrary or irrational." 
    Paoli, 113 F.3d at 453
    . The District Court heard argument on the defendant's
    motion in limine and accompanying arguments concerning
    Bonjo and Martin plea agreements and guilty pleas at three
    separate instances during this criminal proceeding: (1) on
    May 3, 1995, prior to the testimony of FBI Agent Cook
    (App. at 806); (2) on May 9, 1995, prior to the testimony of
    Dr. Paul C. Moock, Jr. (App. at 1768); and (3) subsequent
    to trial in ruling upon the defendants' post-trial motions. At
    each instance, the District Court carefully and meticulously
    weighed the above-mentioned factors of credibility,
    20
    selectivity, and witness knowledge that inform the probative
    value versus prejudicial effect standard required by Federal
    Rule 403. At each instance, the District Court's balancing
    was careful and comprehensive in concluding that the
    probative value of Bonjo and Martin's plea agreements and
    guilty pleas outweighed any prejudicial effect. Recognizing
    our limited role as an appellate court, therefore, we cannot,
    and do not, hold that the District Court acted either
    arbitrarily or irrationally -- and therefore did not abuse its
    discretion -- in admitting Bonjo and Martin's guilty pleas
    and plea agreements over Universal and Lukesh's objection.
    IV
    Having held that the District Court properly exercised its
    discretion in admitting Bonjo and Martin's pleas after
    consideration of the factors relevant to such a decision, it
    is evident that the opinions of United States v. Cohen, 
    171 F.3d 796
    (3d Cir. 1999), United States v. Gaev , 
    24 F.3d 473
    (3d Cir. 1994), United States v. Gambino, 
    926 F.2d 1335
    (3d
    Cir. 1991), and the cases that they followed, as well as
    Judge Rosenn's dissent in United States v. Thomas, 
    998 F.2d 1202
    (3d Cir. 1993), reflect the correct jurisprudence
    in this Circuit in connection with the admission of a
    witness's guilty plea and plea agreement. To the extent,
    therefore, that other decisions of this Court do not comport
    with the analysis or conclusion announced today, they are
    overruled.
    V
    One procedural issue remains to be resolved. It will be
    recalled that the original panel majority had vacated the
    District Court's judgment of conviction and sentence
    pertaining to Universal and Lukesh. Accordingly, the panel
    majority had not found it necessary to address the
    government's cross-appeal that argued that the District
    Court erred in sentencing Lukesh.
    We have held here that the District   Court properly
    admitted the testimony of Bonjo and   Martin as to their plea
    agreements and guilty pleas, and as   a result, the new trial
    that the panel majority directed is   not warranted. Rather,
    21
    our decision today affirms the convictions of both Universal
    and Lukesh.
    Because the panel majority did not find it necessary to
    consider the government's cross-appeal, this Court has
    never rendered a decision as to whether the District Court
    erred in the sentence that it imposed upon Lukesh.
    Moreover, because as earlier noted, this Court -- sitting en
    banc -- did not consider the sentencing issue that the
    government initially raised, that issue is presently still open
    and undecided as a result of our decision to affirm
    Universal and Lukesh's convictions.
    Rather than decide this issue without briefing or
    argument, we will refer the government's issue on
    sentencing to the original panel to determine whether
    resentencing should be ordered to include the relevant
    conduct of acquitted activity pursuant to sections 1B1.3
    and 2F1.1 of the United States Sentencing Guidelines. See
    generally United States v. Watts, 
    519 U.S. 148
    (1997);
    United States v. Baird, 
    109 F.3d 856
    (3d Cir. 1997). In
    addition, the original panel should dispose of the
    government's argument that the District Court should have
    made findings of fact concerning why it declined to consider
    the particular conduct in calculating Universal and
    Lukesh's sentences. See, e.g., E.C. Ernst, Inc. v. Koppers
    Co., 
    626 F.2d 324
    (3d Cir. 1980).
    22
    ROTH, Circuit Judge, dissenting, with whom Judges
    Sloviter, McKee and Rendell join and with whom Chief
    Judge Becker joins except for footnote 12.
    I respectfully dissent from the result reached by the
    majority. The majority has affirmed the District Court's
    admission into evidence of Bonjo and Martin's guilty pleas,1
    over the defendants' objection, despite the defendants'
    agreement not to mention the guilty pleas on cross-
    examination or to raise any inference which these guilty
    pleas might rebut. I believe that in doing so the majority
    deviates from the result mandated by Federal Rules of
    Evidence 403 and 608. Moreover, the majority's holding
    would now make it possible for the government in a
    criminal case to introduce the guilty plea of a defendant's
    accomplice simply by claiming that this evidence must be
    admitted for the jury to properly assess the testifying
    accomplice's credibility. Because I conclude that the
    District Court abused its discretion by admitting the guilty
    pleas into evidence, I would reverse the convictions of
    Lukesh and Universal and remand this case to the District
    Court for a new trial.
    I. A.
    To demonstrate how the majority's opinion deviates from
    our existing precedent, I will first place this case in a
    historical context. In 1949, in United States v. Toner, we
    first considered whether the guilty plea of a conspirator was
    admissible as evidence in the criminal trial of an alleged co-
    conspirator. See United States v. Toner, 
    173 F.2d 140
    (3d
    Cir. 1949). In Toner, we ultimately held that the trial court's
    admission of an alleged co-conspirator's guilty plea,
    combined with a defective limiting instruction, required
    reversal of the defendant's conviction. See 
    id. at 142.
    The
    Toner Court's reasoning, articulated by Judge Goodrich,
    _________________________________________________________________
    1. Like the majority, I believe that the distinction between guilty pleas
    and plea agreements is, in the context of this case, a distinction without
    a difference. 
    See supra
    Majority Opinion at 3. As such, I use the term
    "guilty plea(s)" to refer to guilty plea(s) and/or the corresponding plea
    agreement(s).
    1
    forms the foundation upon which the present case must be
    decided:
    From the common sense point of view[,] a plea of guilty
    by an alleged fellow conspirator is highly relevant upon
    the question of the guilt of another alleged conspirator.
    If A's admission that he conspired with B is believed, it
    is pretty hard to avoid the conclusion that B must have
    conspired with A. This is one of the cases, therefore,
    where evidence logically probative is to be excluded
    because of some countervailing policy. There are many
    such instances in the law.
    The foundation of the countervailing policy is the right
    of every defendant to stand or fall with the proof of the
    charge made against him, not against somebody else.
    Acquittal of an alleged fellow conspirator is not
    evidence for a man being tried for conspiracy. So,
    likewise, conviction of an alleged fellow conspirator
    after a trial is not admissible as against one now being
    charged. The defendant had a right to have his guilt or
    innocence determined by the evidence presented
    against him, not by what has happened with regard to
    a criminal prosecution against someone else. We think
    that the charge given upon this point was contrary to
    that rule and inadvertently, of course, deprived the
    defendant of a very substantial protection to which he
    was entitled.
    See 
    id. (citations omitted).
    As Toner highlighted, the danger
    of unfair prejudice when admitting the guilty plea of a co-
    defendant is more acute if the charge in question is
    conspiracy because a conspiracy requires an agreement
    between two or more individuals. See, e.g., United States v.
    Davis, 
    183 F.3d 231
    , 244 (3d Cir. 1999) ("A conspiracy
    requires agreement between at least two people to the
    illegal object of the conspiracy, though other participants
    need not be indicted.") (citing United States v. Delpit, 
    94 F.3d 1134
    , 1150 (8th Cir. 1996); United States v. Krasovich,
    
    819 F.2d 253
    , 255 (9th Cir. 1987)). If two defendants
    allegedly conspired, and one defendant has been convicted
    or has pleaded guilty, the clear implication is that the other
    defendant is also guilty. This point has been re-emphasized
    in subsequent Third Circuit case law:
    2
    The guilty plea to a conspiracy charge carries with it
    more potential harm to the defendant on trial because
    the crime by definition requires the participation of
    another. The jury could not fail to appreciate the
    significance of this and would realize, as the court said
    in a similar case, United States v. Harrell, 
    436 F.2d 606
    , 614 (5th Cir. 1970), that "it takes two to tango."
    United States v. Gullo, 
    502 F.2d 759
    , 761 (3d Cir. 1974).
    Consistent with our holding in Toner, we have subsequently
    held on many occasions that a witness's guilty plea cannot
    be admitted for the purpose of proving a defendant's guilt.
    See United States v. Cohen, 
    171 F.3d 796
    , 801 (3d Cir.
    1999) ("[T]he plea agreements of co-conspirators are not
    admissible to prove the defendant's guilt."); United States v.
    Gaev, 
    24 F.3d 473
    , 476 (3d Cir. 1994) ("It is well
    established that the plea agreements of co-conspirators
    cannot be used as evidence of a defendant's guilt.");
    Government of the Virgin Islands v. Mujahid, 
    990 F.2d 111
    ,
    115 (3d Cir. 1993) ("It is well-established that a co-
    defendant's guilty plea is not admissible to prove the
    defendant's guilt."); United States v. Werme , 
    939 F.2d 108
    ,
    113 (3d Cir. 1991) ("We have long recognized that evidence
    of another party's guilty plea is not admissible to prove the
    defendant's guilt.").2
    Implicit in, and necessary to, the reasoning of Toner and
    subsequent cases is the principle that if a witness's guilty
    plea is to be admissible at all, it must be admissible for
    some purpose other than proving the defendant's guilt. See
    
    Cohen, 171 F.3d at 801
    (holding that an alleged co-
    conspirator's plea agreement is admissible for "some
    purposes"); 
    Gaev, 24 F.3d at 476
    (holding that an alleged
    co-conspirator's guilty plea is admissible for "some valid
    purpose[s]"); United States v. Thomas, 
    998 F.2d 1202
    , 1205
    (3d Cir. 1993) (holding that an alleged co-conspirator's
    guilty plea is admissible for "limited purposes"); 
    Mujahid, 990 F.2d at 115
    (holding that an alleged co-conspirator's
    guilty plea is admissible for "other[ ] permissible purposes");
    _________________________________________________________________
    2. These cases alone refute the majority's claim that an accomplice's
    guilty plea is presumptively admissible. 
    See supra
    Majority Opinion at
    12.
    3
    
    Werme, 939 F.2d at 113
    (holding that another party's guilty
    plea is admissible for "other[ ] permissible purposes");
    United States v. Gambino, 
    926 F.2d 1355
    , 1363 (3d Cir.
    1991) (holding that an alleged co-conspirator's guilty plea is
    admissible for "some valid purpose[s]"). Thus, the guilty
    plea is inadmissible, as a matter of law, unless presented
    for a valid or permissible evidentiary purpose. See, e.g.,
    
    Thomas, 998 F.2d at 1203-06
    .
    We have then, despite this general rule against the
    introduction of a witness's guilty plea, recognized three
    valid, permissible purposes for which a guilty plea can be
    admitted into evidence. First, it may be admitted"in order
    to rebut defense counsel's persistent attempts on cross-
    examination to raise an inference that the co-conspirators
    had not been prosecuted and that [the defendant] was
    being single out for prosecution." United States v. Inadi,
    
    790 F.2d 383
    , 384 n.2 (3d Cir. 1986).
    Second, a guilty plea may be admitted "on direct
    examination" in order "to dampen subsequent attacks on
    credibility, and to foreclose any suggestion that the party
    producing the witness was concealing evidence." 
    Gambino, 926 F.2d at 1364
    . This situation arises most often when
    the defense plans to attack an accomplice's testimony as
    being fabricated so that he might receive a less severe
    punishment in return for testifying.
    Finally, although not relevant to this case, a guilty plea
    may be admitted "to rebut the defense assertion that [the
    witness] was acting as a government agent when he
    engaged in the activities that formed the basis for[his
    guilty] plea." 
    Werme, 939 F.2d at 114
    .
    In addition, some Third Circuit cases have suggested (in
    dicta) a fourth permissible or valid purpose. For example, in
    Gaev we suggested that, "[i]t may also be proper to
    introduce a witness's guilty plea to explain hisfirsthand
    knowledge of the defendants' misdeeds." Gaev , 24 F.3d at
    476 (emphasis added) (citing United States v. Halbert, 
    640 F.2d 1000
    , 1005 (9th Cir. 1981)). I am left wondering,
    however, how the introduction of a witness's guilty plea into
    evidence establishes the basis for his or her firsthand
    knowledge of the crime. Presumably, all that the
    4
    introduction of the guilty plea establishes is that the
    witness pleaded guilty. It is the witness's testimony itself
    that establishes the basis for his or her firsthand
    knowledge of the crime--the witness has firsthand
    knowledge because s/he was present during or participated
    in the crime, not because s/he pleaded guilty to the crime.
    B.
    In the present case, because the defendants agreed not to
    challenge the witnesses' credibility based on their plea
    agreements, we are presented with a more focused question
    than we met in Toner: Whether and under what
    circumstances a trial court can admit into evidence the
    guilty plea of an alleged accomplice, over the defendant's
    objection, when the defendant agrees not to mention the
    guilty plea on cross-examination and not "to raise any
    inference on which the accomplices' pleas of guilty would
    be admissible to rebut."3
    In United States v. Thomas, 
    998 F.2d 1204
    (3d Cir.
    1993), we first considered this more restricted issue. The
    District Court in Thomas had admitted two co-conspirators'
    guilty pleas into evidence, concluding that admission was
    proper for the limited purposes of "aid[ing] the jury in
    assessing [the witnesses'] credibility,"establish[ing] the
    [witnesses'] acknowledgment of their participation in the
    offense," and "counter[ing] the inference that [the witnesses]
    had not been prosecuted." 
    Thomas, 998 F.2d at 1204
    . In
    reviewing the trial court's decision to admit the guilty pleas
    into evidence, we noted that the Third Circuit had
    recognized two relevant, valid or permissible purposes for
    which an alleged co-conspirator's guilty plea could be
    introduced into evidence, "to blunt the impact on a
    government witness's credibility of having evidence of a
    _________________________________________________________________
    3. Both defendants joined the motion in limine to exclude the guilty pleas
    of the two alleged accomplices. The motion stated in relevant part,
    "Defendant asserts that at trial of this action he will not raise the
    guilty
    plea/plea agreements on cross examination nor seek to raise any
    inference on which the accomplices' pleas of guilty would be admissible
    to rebut." Supplemental Brief for the Appellants at 23; 
    see supra
    Majority Opinion at 6, note 6.
    5
    guilty plea brought out on cross examination by the
    defense," and "to prevent any improper inference by the
    jury that the defendant has been singled out for
    prosecution while the co-conspirators have not been
    prosecuted." 
    Id. at 1205.
    We reasoned, however, that
    neither purpose justified admitting the guilty pleas into
    evidence, because the defendant had agreed not to
    challenge the witnesses' credibility based on their guilty
    pleas, and because the defendant had not suggested he was
    being selectively prosecuted. See id.4 We rejected the
    District Court's claim that the alleged co-conspirators'
    guilty pleas were admitted into evidence in order to
    establish their acknowledgment of their participation in the
    crime, pointing out that defense counsel did not challenge
    the witnesses' assertion that they participated in the crime.
    See 
    id. Balancing the
    danger of unfair prejudice associated with
    the admission of the guilty pleas against their probative
    value pursuant to Federal Rule of Evidence 403, we
    ultimately held in Thomas that, "[i]n the absence of a
    proper purpose for the admission of the guilty pleas, the
    curative instructions of the district court were not sufficient
    to remove the prejudice to Thomas presented by the
    evidence of his co-conspirators's [sic] guilty pleas." 
    Id. at 1206.
    We concluded that we were "not left with the
    requisite ``sure conviction that the error did not prejudice
    the defendant' " and thus concluded that "the introduction
    at trial of evidence of Thomas's co-conspirators's[sic] guilty
    _________________________________________________________________
    4. In Thomas, we concluded that the case at hand differed from United
    States v. Inadi where the alleged co-conspirator's guilty plea was
    admitted only "to rebut defense counsel's persistent attempts on cross-
    examination to raise an inference that the co-conspirator's had not been
    prosecuted and [that] the defendant was being singled out for
    prosecution." 
    Thomas, 998 F.2d at 1205
    (citing United States v. Inadi,
    
    790 F.2d 383
    , 384 n.2. (3d Cir. 1986)). We noted that if the defendant
    violated the agreement and "attempted to raise an inference on cross-
    examination that [the defendant] was being unfairly singled out for
    prosecution, additional remedial steps could [then] have been taken." 
    Id. at 1205
    n.1. Presumably, "additional remedial steps" would have
    included introducing the alleged co-conspirator's guilty plea into
    evidence on rebuttal.
    6
    pleas was reversible error." 
    Id. at 1207
    (quoting United
    States v. Jannotti, 
    729 F.2d 213
    , 219-20 (3d Cir. 1984)).
    Judge Rosenn filed a vigorous dissent in Thomas, arguing
    that the alleged co-conspirators' guilty pleas were properly
    admitted "(1) to bolster the credibility of the co-conspirators
    as prosecution witnesses; (2) to quell the inference that the
    co-conspirators were not prosecuted and that Thomas was
    thus ``singled out' for punishment; and (3) to establish the
    basis for the co-conspirators' firsthand knowledge of the
    crime about which they testified." 
    Id. at 1208
    (Rosenn, J.,
    dissenting). Contending that the alleged co-conspirators'
    credibility would be at issue regardless of the defense's
    assurance that it would not attack the witnesses' credibility
    with respect to their guilty pleas, Judge Rosenn
    acknowledged that his dissent was at odds with the Third
    Circuit's holding in Toner: "One could argue that credibility
    is always at issue and that my position thus effectively
    overrules Toner." 
    Id. at 1209.
    However, Judge Rosenn
    argued that his position was in fact consistent with the
    holding in Toner:
    [A] witness's credibility is only at issue when he or she
    testifies about a relevant and disputed fact. Moreover,
    Toner merely states that a guilty plea of a witness
    cannot be used to establish the guilt of the defendant.
    Thus, even if the guilty plea is always admissible for
    the purpose of establishing the credibility of the
    witness, that does not overrule Toner: Toner would still
    require a limiting instruction, similar to the ones given
    by the trial judge in the present case, to insure that
    the jury understands that the guilty plea cannot be
    used to establish the guilt of the defendant.
    
    Id. I cannot,
    however, accept the implications of this
    explanation, just as I cannot accept the majority's position,
    unless there has been a meaningful weighing of the
    probative value of the guilty pleas against the danger of
    unfair prejudice, as required by Federal Rule of Evidence
    403.
    7
    C.
    Subsequent to our decision in Thomas, we again
    addressed whether the trial court erred by admitting into
    evidence the guilty plea of an alleged co-conspirator, even
    though the defendant agreed not to challenge the alleged
    co-conspirator's credibility nor to raise any inference that
    would make the guilty plea admissible. See United States v.
    Gaev, 
    24 F.3d 473
    , 474-79 (3d Cir. 1994). On facts nearly
    identical to those in Thomas, we held in Gaev that the
    alleged co-conspirators' guilty pleas had been properly
    admitted into evidence. See 
    id. at 479.
    In conducting the
    requisite Rule 403 balancing, we concluded, consistent with
    Judge Rosenn's dissent in Thomas, that "[w]hen a co-
    conspirator testifies that he took part in the crime with
    which the defendant is charged, his credibility will
    automatically be implicated." 
    Gaev, 24 F.3d at 477
    (emphasis added). Ultimately, in Gaev we went beyond the
    confines of Judge Rosenn's dissent in Thomas , holding that
    a witness's credibility in a case like Thomas will
    "automatically" be at issue. Prior to Gaev , this proposition,
    that "[w]hen a co-conspirator testifies that he took part in
    the crime with which the defendant is charged, his
    credibility will automatically be implicated," had not arisen
    in Third Circuit jurisprudence. The consequences of the
    extension of such an expansive interpretation of our prior
    case law are illustrated by the majority's opinion in this
    case.
    II. A.
    Federal Rule of Evidence 403 states that:
    Although relevant, evidence may be excluded if its
    probative value is substantially outweighed by the
    danger of unfair prejudice, confusion of the issues, or
    misleading the jury, or by considerations of undue
    delay, waste of time, or needless presentation of
    cumulative evidence.
    Thus, evidence that is otherwise admissible and probative
    of guilt must sometimes be excluded because of the danger
    of unfair prejudice to the defendant. See, e.g. , United States
    v. Sriyuth, 
    98 F.3d 739
    , 746 (3d Cir. 1996).
    8
    The District Court, in balancing the danger of unfair
    prejudice associated with Bonjo and Martin's guilty pleas
    against their probative value, concluded that the probative
    value was not substantially outweighed by the danger of
    unfair prejudice. The majority, endorsing this conclusion,
    states:
    The District Court heard argument on the defendant's
    [sic] motion in limine and accompanying arguments
    concerning Bonjo and Martin plea agreements and
    guilty pleas at three separate instances during this
    criminal proceeding: (1) on May 3, 1995, prior to the
    testimony of FBI Agent Cook (App. at 806); (2) on May
    9, 1995, prior to the testimony of Dr. Paul C. Moock,
    Jr. (App. at 1768); and (3) subsequent to trial in ruling
    upon the defendants' post-trial motions. At each
    instance, the District Court carefully and meticulously
    weighed the . . . factors of credibility, selectivity, and
    witness knowledge that inform the probative value
    versus prejudicial effect standard required by Federal
    Rule 403. At each instance, the District Court's
    balancing was careful and comprehensive in
    concluding that the probative value of Bonjo and
    Martin's plea agreements and guilty pleas outweighed
    any prejudicial effect.
    Majority Opinion at 20-21. The record, however, belies this
    contention.
    On May 3, 1995, prior to the testimony of FBI Agent
    Cook, the District Court first heard argument on the
    defendants' motion in limine. See App. at 806-17.5 After
    _________________________________________________________________
    5. The record suggests that May 3, 1995, was actually the last time that
    the District Court heard arguments on the defendants' motion in limine.
    The District Court stated:
    All right, I asked you to come at this point so that we could have
    a
    last opportunity to argue the motion in limine   and I addressed
    your
    attention to the Gave [sic] case. Anyone wish to make any
    additional
    arguments, you may do so.
    App. at 806. Regardless, this exchange on May 3, 1995, is the first point
    in the record at which the District Court heard arguments on the
    defendants' motion in limine.
    9
    hearing argument on the motion, the District Court did not
    "carefully and meticulously weigh[ ] the. . . factors of
    credibility, selectivity, and witness knowledge that inform
    the probative value versus prejudicial effect standard
    required by Federal Rule 403," nor did the District Court
    "careful[ly] and comprehensive[ly]" conclude "that the
    probative value of Bonjo and Martin's plea agreements and
    guilty pleas outweighed any prejudicial effect." Rather, the
    District Court simply stated: "I'll take all the time I have
    available to think about this." App. at 816.
    On May 9, 1995, prior to Dr. Paul C. Moock's testimony,
    the District Court ruled on the defendants' motion in limine.
    The District Court did not hear further argument on the
    motion, nor did the District Court "carefully and
    meticulously weigh[ ] the . . . factors of credibility,
    selectivity, and witness knowledge that inform the probative
    value versus prejudicial effect standard required by Federal
    Rule 403." The District Court simply made the following
    statement:
    All right, I have weighed all of the factors and I think
    in the context of this case we have had and from what
    I know of or have heard by way of reference to Julia
    Blum [Bonjo] and Penny Martin, I think it sounds to
    me as if they are somewhat higher up in the structure.
    And if they testify the jury is going to certainly wonder
    whether or not they have been charged. It's going to
    wonder perhaps what they have been promised by the
    prosecutor if anything and what they may be getting in
    return for their testimony.
    I think in weighing all those factors with the possible
    prejudice that I am going to allow the Government to
    bring out the fact of the guilty plea and the fact of the
    guilty plea agreement. . . .
    I think this is exactly like the Gave [sic] case, only
    there are more reasons here, because there are so
    many people who have testified and in their testimony
    have indicated a certain amount of wrong doing. And
    they--it's pretty obvious haven't been charged and I
    think it raises a very serious question in the minds of
    the jury, especially as to people who are as I said
    10
    before, higher up in the structure. What are they
    getting for their testimony, how is it that these people
    haven't been charged and it's better in my opinion that
    the jury know it all. That's the basis of the reason.
    App. at 1768, 1771-72. The language quoted above clearly
    indicates that the District Court did little if any balancing
    but instead simply concluded that Bonjo and Martin's
    guilty pleas were admissible. In fact, the District Court
    mentioned only two of the factors that the majority
    highlights, glossing over them in cursory form:first,
    credibility, "what are they getting for their testimony," and,
    second, selective prosecution, "how is it that these people
    haven't been charged." Moreover, no mention is made by
    the District Court of the defendants' commitment not to
    raise these issues or of the possibility of admitting the pleas
    on rebuttal if the defendants reneged on their commitment.
    The majority's characterization of the District Court's Rule
    403 analysis as "careful," "meticulous" and
    "comprehensive" is undermined by this cursory Rule 403
    analysis.
    B.
    As set forth in Federal Rule of Evidence 403, and as the
    majority acknowledges, this case turns on whether the
    District Court properly weighed the probative value of Bonjo
    and Martin's guilty pleas against the danger of unfair
    prejudice to the defendants. Because a proper Rule 403
    analysis must consider both the probative value of the
    guilty pleas, as well as the danger of unfair prejudice
    associated with the pleas, I will first assess their probative
    value.
    The District Court concluded that the probative value of
    Bonjo and Martin's guilty pleas was limited to eliminating
    the appearance of selective prosecution and to informing
    the jury what the witnesses were receiving in exchange for
    their testimony. It is beyond question, however, that the
    probative value of this type of information would have been
    minimized by the defendants' commitment not to "raise the
    guilty plea/plea agreements on cross examination nor[ ] to
    raise any inference on which the accomplices' pleas of
    11
    guilty would be admissible to rebut." The credibility attack,
    based on any quid pro quo that the witnesses derived from
    the plea agreements, would not take place if the defendants
    refrained from employing this line of attack in their cross-
    examination.
    I am firmly convinced, moreover, that the evaluation of
    probative value cannot be made without a consideration of
    the defendants' commitment. The majority disregards the
    commitment, however, and focuses on the probative value
    associated with assisting the jury in assessing the
    credibility of the accomplices in response to jury
    speculation or in response to the defense's cross-
    examination attacking a witness's credibility -- a stage of
    the trial which need not occur if the defendants lived up to
    their commitment.
    In adopting this focus, the majority skirts the line
    between pointing out that these guilty pleas may have
    probative value and declaring that the guilty pleas
    themselves constitute substantive evidence of the
    defendants' guilt. It is black letter law, as the majority
    acknowledges, that a witness's guilty plea cannot be
    admitted as substantive evidence of a defendant's guilt. See
    
    Cohen, 171 F.3d at 801
    ("[T]he plea agreements of co-
    conspirators are not admissible to prove the defendant's
    guilt."); 
    Gaev, 24 F.3d at 476
    ("It is well established that
    the plea agreements of co-conspirators cannot be used as
    evidence of a defendant's guilt."); Mujahid , 990 F.2d at 115
    ("It is well-established that a co-defendant's guilty plea is
    not admissible to prove the defendant's guilt."); 
    Werme, 939 F.2d at 113
    ("We have long recognized that evidence of
    another party's guilty plea is not admissible to prove the
    defendant's guilt."). Nevertheless, by ignoring the
    defendants' agreement not to "raise the guilty plea/plea
    agreements on cross examination nor [ ] to raise any
    inference on which the accomplices' pleas of guilty would
    be admissible to rebut" the majority fails to appreciate that,
    in light of defendants' commitment not to raise the issue of
    the pleas, the probative value of Bonjo and Martin's guilty
    pleas is negligible. Moreover, the jury will then be presented
    with evidence that has minimal probative value but which
    12
    may improperly imply that because Bonjo and Martin pled
    guilty, Lukesh and Universal are also guilty.6
    C.
    Having considered the probative value of Bonjo and
    Martin's guilty pleas, we must next assess the danger of
    unfair prejudice associated with admitting their guilty pleas
    into evidence. As the majority acknowledges, and as we
    have previously noted, "[t]he guilty plea to a conspiracy
    charge carries with it more potential harm to the defendant
    on trial because the crime by definition requires the
    participation of another." United States v. Gullo, 
    502 F.2d 759
    , 761 (3d Cir. 1974). It is true that the defendants were
    convicted of mail fraud and not of conspiracy. Nevertheless,
    the offense of conviction, as it was presented at trial, in
    many respects was similar to a conspiracy. In order to
    obtain a mail fraud conviction under 18 U.S.C. S 1341, the
    government must prove that the defendant devised a
    scheme to defraud, that the defendant participated in the
    scheme with the specific intent to defraud and that the
    defendant could reasonably foresee use of the mails. See
    United States v. Feola, 
    420 U.S. 671
    , 693 (1975); Pereira v.
    United States, 
    347 U.S. 1
    , 8 (1954); United States v.
    Pflaumer, 
    774 F.2d 1224
    , 1233 (3d Cir. 1985). As the
    scheme to defraud was described in the indictment and
    presented at trial, defendants, including Lukesh, Universal,
    and Bonjo, participated together in the scheme to defraud
    and obtain money from the Medicare program. Indeed, it
    would appear that the government could have elected to
    indict the defendants on a conspiracy count as well as on
    the substantive mail fraud counts.
    I find, however, that the majority trivializes the
    heightened danger of unfair prejudice presented by this
    type of situation, a situation that requires closer scrutiny of
    the Rule 403 balance. See Majority Opinion at 20. In the
    context of this case, the majority's characterization of the
    offense to which Bonjo and Martin pleaded guilty as a
    _________________________________________________________________
    6. will deal further with two other aspects of the probative value of the
    guilty pleas in my discussion of Rule 608 in Section IV and of limiting
    instructions in Section V.
    13
    "substantive count[ ]" while legally accurate, is also
    misleading. In the case of Universal and Lukesh, section
    1341 criminalized what was essentially a successful
    conspiracy to commit Medicare fraud. In fact, the jury
    found that Lukesh and Universal had devised a scheme to
    defraud Medicare by fraudulently re-writing and altering
    patient evaluations to increase the likelihood that Medicare
    would reimburse Universal for medical services that were
    not otherwise reimbursable. Bonjo and Martin pled guilty to
    participating in this scheme. Ultimately, on the facts before
    us, the distinction that the majority attempts to draw,
    between the "substantive" count of mail fraud under section
    1341 and the "non-substantive" count of conspiracy to
    commit mail fraud under section 371, is a distinction
    without a difference. Thus, the danger of unfair prejudice
    associated with the District Court's decision to admit Bonjo
    and Martin's guilty pleas into evidence is not only
    significant but also virtually identical to the danger of
    unfair prejudice associated with admitting into evidence the
    guilty pleas of two alleged co-conspirators.
    D.
    Having considered both the probative value of and the
    danger of unfair prejudice associated with Bonjo and
    Martin's guilty pleas, we must next determine whether the
    probative value of these guilty pleas is substantially
    outweighed by the danger of unfair prejudice to the
    defendants. The probative value of Bonjo and Martin's
    guilty pleas is negligible--the defendants agreed not to
    "raise the guilty plea/plea agreements on cross examination
    nor [ ] to raise any inference on which the accomplices'
    pleas of guilty would be admissible to rebut." The principal
    effect of this agreement is a reduction in the probative value
    of this evidence. On the flip side, the danger of unfair
    prejudice associated with Bonjo and Martin's guilty pleas is
    significant--mail fraud, as a matter of law, involves a
    scheme or artifice to defraud, and Bonjo and Martin
    allegedly participated in this scheme with and under the
    direction of Universal and Lukesh. Thus, if Bonjo and
    Martin's admission that they committed mail fraud is
    believed, it is difficult not to conclude that Universal and
    14
    Lukesh committed mail fraud as well. As we noted in Toner,
    "[a] defendant ha[s] a right to have his guilt or innocence
    determined by the evidence presented against him, not by
    what has happened with regard to a criminal prosecution
    against someone else." 
    Toner, 173 F.2d at 142
    . Clearly,
    Bonjo and Martin's guilty pleas create a significant danger
    of unfair prejudice. This significant danger of unfair
    prejudice substantially outweighs the minimal probative
    value of Bonjo and Martin's guilty pleas. For that reason,
    Federal Rule of Evidence 403 mandates that their guilty
    pleas be excluded. Thus, the District Court's decision to
    admit Bonjo and Martin's guilty pleas into evidence was an
    abuse of discretion.
    III.
    By concluding that Bonjo and Martin's guilty pleas were
    properly admitted into evidence, and by endorsing the
    holding in Gaev, the majority ignores the fact that, over
    time, Toner and its progeny have come to stand for the
    proposition that guilty pleas of co-conspirators are not
    admissible to establish the guilt of the defendant and can
    only be introduced into evidence for a proper evidentiary
    purpose. See, e.g., United States v. Gambino, 
    926 F.2d 1355
    , 1363 (3d Cir. 1991); 
    Werme, 939 F.2d at 113
    -14;
    
    Mujahid, 990 F.2d at 115
    . Following the majority's
    reasoning, unless a defendant is willing to refrain from
    cross-examining a witness entirely, the witness's credibility
    will always be at issue, and his or her guilty plea will
    always be admissible. While this may be the rule of law in
    other circuits, it is definitely not the rule of law in the Third
    Circuit. Compare, e.g., United States v. Mealy, 
    851 F.2d 890
    , 899 (7th Cir. 1988) ("The well established rule in this
    circuit is that, on direct examination, the prosecutor may
    elicit direct testimony regarding the witness's plea
    agreement and actually introduce the plea agreement into
    evidence.") with 
    Gambino, 926 F.2d at 1363
    (holding that
    an alleged co-conspirator's guilty plea can be admitted into
    evidence only for a proper evidentiary purpose). The
    majority's holding effectively overrules Toner and its
    15
    progeny without acknowledging this fact or providing a
    reason for doing so.7
    The majority apparently concludes that Toner stands for
    the proposition that an alleged co-conspirator's guilty plea
    cannot be offered as proof of the defendant's guilt;
    therefore, when an alleged co-conspirator's guilty plea is
    admitted into evidence, the jury must be instructed that the
    guilty plea cannot be used to establish the guilt of the
    defendant. While this may be a proper interpretation of
    Toner read alone, subsequent cases in the Third Circuit
    have recognized that, absent a proper purpose, guilty pleas
    of an alleged co-conspirator are inadmissible. Framed in
    terms of the balancing approach required by Federal Rule
    of Evidence 403, absent a proper purpose, the probative
    value of an alleged co-conspirator's guilty plea is
    substantially outweighed by the danger of unfair prejudice
    to the defendants.
    In light of our established precedent, I believe that the
    trial court in Universal erred by admitting into evidence the
    guilty pleas of two alleged co-schemers in face of the
    defendants' commitment that they would not, on cross-
    examination, challenge the credibility of the government's
    witnesses or raise any inferences that would make the
    guilty pleas admissible. Absent a proper evidentiary
    purpose, a trial court's decision to admit an alleged co-
    conspirator's guilty plea is improper and an abuse of
    _________________________________________________________________
    7. The majority is quick to focus on the following statement in Gaev:
    "While plea agreements have often been admitted in response to actual
    or anticipated attacks on a witness's credibility, an attack is not always
    necessary to justify their introduction," 
    Gaev, 24 F.3d at 477
    -78. To
    support this proposition, the Gaev Court cites the following passage in
    Gambino: "In this case, the defendants began their attack on the
    credibility of the government's witnesses in their opening statement. Yet,
    even in the absence of this attack, the [introduction of the witnesses'
    guilty pleas] was proper here." Gambino , 926 F.2d at 1363. This
    statement, which is clearly dictum, is made without any supporting cite
    to case law in the Third Circuit or any other circuit. Such a statement
    is without support or foundation in Third Circuit jurisprudence, and
    since it is merely dictum, it alone should not provide the basis for
    affirming the District Court's decision to admit Bonjo and Martin's guilty
    pleas into evidence.
    16
    discretion. An alleged co-conspirator's guilty plea cannot be
    admitted for the purpose of proving a defendant's guilt. See
    
    Cohen, 171 F.3d at 801
    ("[T]he plea agreements of co-
    conspirators are not admissible to prove the defendant's
    guilt."); 
    Gaev, 24 F.3d at 476
    ("It is well established that
    the plea agreements of co-conspirators cannot be used as
    evidence of a defendant's guilt."); Mujahid , 990 F.2d at 115
    ("It is well-established that a co-defendant's guilty plea is
    not admissible to prove the defendant's guilt."); 
    Werme, 939 F.2d at 113
    ("We have long recognized that evidence of
    another party's guilty plea is not admissible to prove the
    defendant's guilt."). Contrary to the majority's claim that
    "Federal Rule of Evidence 403 creates a presumption of
    admissibility," an alleged co-conspirator's guilty plea is only
    admissible for a limited number of valid, permissible
    purposes. See United States v. Inadi, 
    790 F.2d 383
    , 384 n.2
    (3d Cir. 1986) ("[A co-conspirator's guilty plea may be
    admitted] in order to rebut defense counsel's persistent
    attempts on cross-examination to raise an inference that
    the co-conspirators had not been prosecuted and that[the
    defendant] was being singled out for prosecution.");
    
    Gambino, 926 F.2d at 1364
    ("[A co-conspirator's guilty plea
    may be admitted] on direct examination [in order] to
    dampen subsequent attacks on credibility, and to foreclose
    any suggestion that the party producing the witness was
    concealing evidence."); 
    Werme, 939 F.2d at 114
    ("[A
    witness's guilty plea may be admitted] to rebut the defense
    assertion that [the witness] was acting as a government
    agent when he engaged in the activities that formed the
    basis for [his guilty] plea.").
    As our analysis above demonstrates, when a defendant
    agrees not to "raise the guilty plea/plea agreements on
    cross examination nor to raise any inference on which the
    accomplices' pleas of guilty would be admissible to rebut,"
    the Rule 403 balance clearly tips in favor of excluding the
    evidence.8 If an alleged co-conspirator's guilty plea is to be
    _________________________________________________________________
    8. As discussed below, the jury's verdict confirms that the defendants
    were in fact prejudiced by the District Court's erroneous evidentiary
    ruling. See infra Section VI. I note moreover that if a defendant reneges
    on a commitment not to impeach a witness's credibility on the basis of
    the guilty plea, the government will have the opportunity to introduce
    the guilty plea on rebuttal.
    17
    admissible at all, it must be admissible for some purpose
    other than proving the defendant's guilt. See 
    Cohen, 171 F.3d at 801
    (holding that an alleged co-conspirator's plea
    agreement is admissible for "some purposes"); 
    Gaev, 24 F.3d at 476
    (holding that an alleged co-conspirator's guilty
    plea is admissible for "some valid purpose[s]"); United
    States v. Thomas, 
    998 F.2d 1202
    , 1205 (3d Cir. 1993)
    (holding that an alleged co-conspirator's guilty plea is
    admissible for "limited purposes"); 
    Mujahid, 990 F.2d at 115
    (holding that an alleged co-conspirator's guilty plea is
    admissible for "other[ ] permissible purposes"); 
    Werme, 939 F.2d at 113
    (holding that another party's guilty plea is
    admissible for "other[ ] permissible purposes"); United
    States v. Gambino, 
    926 F.2d 1355
    , 1363 (3d Cir. 1991)
    (holding that an alleged co-conspirator's guilty plea is
    admissible for "some valid purpose[s]"). Allowing the
    government, when prosecuting a criminal case, to introduce
    the guilty plea of a defendant's alleged co-conspirator
    simply by claiming that the guilty plea must be admitted
    into evidence so that the jury can assess the witness's
    credibility creates an exception that swallows the rule. The
    government will always be able to claim that a witness's
    guilty plea must be admitted into evidence so that the jury
    can assess the witness's credibility, and thus the guilty plea
    will always be admissible. It is impossible to reconcile this
    result with our prior jurisprudence or with the result
    mandated by Rule 403.
    IV.
    Focusing primarily on the jury's need to assess the
    credibility of Bonjo and Martin, and relying on a statement
    in Gaev and cases in other circuits, the majority concludes
    that the government may seek to introduce a witness's
    guilty plea even in the absence of a challenge to the
    witness's credibility. The majority's holding deviates not
    only from the outcome mandated by Rule 403, its holding
    is at odds with Federal Rule of Evidence 608(a) and (b).
    Rule 608(a) states:
    The credibility of a witness may be attacked or
    supported by evidence in the form of opinion or
    reputation, but subject to these limitations: (1) the
    18
    evidence may refer only to character for truthfulness or
    untruthfulness, and (2) evidence of truthful character
    is admissible only after the character of the witness for
    truthfulness has been attacked by opinion or
    reputation evidence or otherwise.
    Arguably, under Rule 608(a), absent an attack on Bonjo
    and Martin's credibility, their guilty pleas are inadmissible.
    The Advisory Committee Notes to Rule 608(a), which
    summarize the policy behind the rule, indicate:
    Character evidence in support of credibility is
    admissible under the rule only after the witness'
    character has first been attacked, as has been the case
    at common law. Maguire, Weinstein, et al., Cases on
    Evidence 295 (5th ed. 1965); McCormick S 49, p. 105;
    4 Wigmore S 1104. The enormous needless
    consumption of time which a contrary practice would
    entail justifies the limitation.
    Thus, even prior to the enactment of Rule 608(a), as a
    matter of common law, evidence was admissible to bolster
    a witness's credibility only after the witness's credibility had
    been attacked. See, e.g., Perkins v. United States, 
    315 F.2d 120
    , 123 (9th Cir. 1963) (highlighting "the general rule that
    until the credibility of a witness has been attacked by
    evidence pertaining to credibility, evidence tending to
    establish credibility is inadmissible") (citing Homan v.
    United States, 
    279 F.2d 767
    , 772 (8th Cir. 1960)).
    Not only is the majority's holding contrary to Rule 608(a),
    its holding is also at odds with Rule 608(b). Rule 608(b)
    states:
    Specific instances of the conduct of a witness, for the
    purpose of attacking or supporting the witness'
    credibility, other than conviction of crime as provided
    in Rule 609, may not be proved by extrinsic evidence.
    They may, however, in the discretion of the court, if
    probative of truthfulness or untruthfulness, be
    inquired into on cross-examination of the witness (1)
    concerning the witness' character for truthfulness or
    untruthfulness, or (2) concerning the character for
    truthfulness or untruthfulness of another witness as to
    19
    which character the witness being cross-examined has
    testified.
    Because Bonjo and Martin's guilty pleas (or more
    specifically their decision to plead guilty) could be
    considered conduct under Rule 608(b), to the extent that
    the government introduced Bonjo and Martin's guilty pleas
    to support their credibility, their admission is barred, as a
    matter of law, by Rule 608(b). See Fed. R. Evid. 608(b); cf.,
    e.g., United States v. Anderson, 
    859 F.2d 1171
    , 1178 (3d
    Cir. 1988) ("To the extent that [the probation officer's]
    testimony was an attempt to attack [the witness's]
    credibility by extrinsic evidence, it is strictly prohibited by
    Federal Rule of Evidence 608(b).").9 Indeed, the government
    argued in its briefs and during oral argument that Bonjo
    and Martin's guilty pleas should be admitted into evidence
    in order better to allow the jury to assess their credibility.
    Certainly, since Bonjo and Martin were government
    witnesses, their guilty pleas were not being introduced into
    evidence to attack their credibility but rather to bolster it.
    Consequently, the majority's conclusion that Bonjo and
    Martin's guilty pleas were properly admitted into evidence is
    not only contrary to the result mandated under Federal
    Rule of Evidence 403 but also is at odds with the Federal
    Rule of Evidence 608.10
    _________________________________________________________________
    9. Extrinsic evidence under Rule 608(b) is admissible for purposes other
    than supporting or attacking a witness's credibility. See, e.g., Lamborn
    v.
    Dittmer, 
    873 F.2d 522
    , 528 (2d Cir. 1989) ("[Rule 608] is inapplicable in
    determining the admissibility of evidence introduced to impeach a
    witness's testimony as to a material issue."). While the majority
    concludes that Bonjo and Martin's guilty pleas are admissible for
    purposes other than evaluating their credibility, i.e., avoiding the
    appearance of selective prosecution and establishing a basis for the
    witness's knowledge of the crime, that the guilty pleas were admitted to
    allow the jury to evaluate the witnesses' credibility is the cornerstone
    of
    the majority's holding.
    10. As the majority points out, it is arguable whether Federal Rule of
    Evidence 608 governs the admission of Bonjo and Martin's guilty pleas.
    
    See supra
    Majority Opinion at 17-18, note 13. However, even if one were
    to conclude that Rule 608 does not govern the admission of Bonjo and
    Martin's guilty pleas, it is clear that Rule 608 provides insight into the
    appropriate balancing required under Rule 403. Specifically, Rule 608
    20
    V.
    While the majority's conclusion, that the District Court
    did not abuse its discretion by admitting into evidence
    Bonjo and Martin's guilty pleas, is disturbing, equally
    disturbing is the majority's conclusion that "the detailed
    limiting instructions provided by the District Court cured
    the prejudicial effect, if any, flowing from the introduction
    of Bonjo and Martin's guilty pleas and plea agreements."
    Majority Opinion at 20.
    _________________________________________________________________
    allows a party to introduce "evidence in the form of opinion or
    reputation" to attack or support the credibility of a witness only after
    the
    credibility of the witness has been attacked. The majority contends that
    Bonjo and Martin's guilty pleas are admissible to bolster their
    credibility
    despite the defendants' agreement not to attack Bonjo and Martin's
    credibility. This contention is at odds with the framework set forth in
    Rule 608. To admit Bonjo and Martin's guilty pleas, absent a prior attack
    on their credibility, when similar evidence would, as a matter of law, be
    admissible under Rule 608 only after a testifying witness's credibility
    had
    been attacked, undermines the majority's entire Rule 403 analysis.
    Moreover, the majority's analysis of United States v. Old Chief is also
    at odds with the framework set forth in Rule 608. In arguing that the
    introduction of Bonjo and Martin's guilty pleas has less probative value
    than the defendants' agreement not to mention the guilty pleas on cross-
    examination or to raise any inference which these guilty pleas might
    rebut, the majority overlooks the fact that "evidence in the form of
    opinion or reputation" is admissible only after the credibility of a
    witness
    has been attacked. See Majority Opinion at 16. Thus, under Rule 608,
    the comparison of probative value required under Old Chief and alluded
    to by the majority would be purely hypothetical and unnecessary; absent
    a prior attack on credibility, "evidence in the form of opinion or
    reputation" is, as a matter of law, inadmissible.
    Finally, contrary to the majority's suggestion, the potential
    applicability of Rule 608 was not only discussed at the en banc oral
    argument, the government filed a supplemental brief after oral argument
    to address the issue. See Supplemental Brief of Appellee United States
    of America, Filed November 22, 1999 ("At oral argument before the en
    banc Court on November 8, 1999, the Court raised two issues which had
    not previously been addressed in this appeal: (1) The relevance of Rule
    608 of the Federal Rules of Evidence; and (2) the applicability of Luce v.
    United States, 
    469 U.S. 38
    (1984).").
    21
    It is beyond dispute that when an alleged co-conspirator's
    guilty plea is admitted into evidence, even if the trial court
    has given a proper cautionary instruction to the jury, the
    prejudice to the defendant may be serious enough to
    constitute reversible error. See, e.g., 
    Thomas, 998 F.2d at 1206
    ("In the absence of a proper purpose for the
    admission of the guilty pleas, the curative instructions of
    the district court were not sufficient to remove the prejudice
    to Thomas presented by the evidence of his co-conspirators'
    guilty pleas."); 
    Gaev, 24 F.3d at 478
    ("There may also be
    cases where the inference of guilt from the co-conspirator's
    plea agreement is sufficiently strong that even limiting
    instructions will not effectively contain it."). The majority
    not only concludes that this prejudicial effect is typically
    cured by a limiting instruction to the jury but also
    dismisses the defendants' contention that juries cannot
    comprehend or follow such limiting instructions.
    Moreover, the majority's analysis obscures what I
    consider to be the key issue: The District Court abused its
    discretion by admitting into evidence Martin and Bonjo's
    guilty pleas, over the defendants' objection, despite the fact
    the defendants agreed not to "raise the guilty plea/plea
    agreements on cross examination nor [ ] to raise any
    inference on which the accomplices' pleas of guilty would
    be admissible to rebut." While a limiting instruction given
    by a District Court may render an otherwise erroneous
    evidentiary ruling harmless, a limiting instruction cannot
    transform an otherwise erroneous evidentiary ruling into a
    legally proper evidentiary ruling. Ultimately, we must decide
    whether, the District Court, at the time it ruled on the
    defendants' motion in limine, abused its discretion by
    admitting Bonjo and Martin's guilty pleas into evidence. To
    do so, we must focus on the probative value and danger of
    unfair prejudice associated with Bonjo and Martin's guilty
    pleas and not on whether the District Court's limiting
    instructions cured any resulting, unfair prejudice.
    Moreover, the danger of unfair prejudice highlighted
    above renders both baffling and confounding the District
    Court's decision to instruct the jury "that it may not
    consider the guilty plea and/or plea agreement as evidence
    that the defendant is guilty of the offenses with which he is
    22
    charged," rather than to instruct the jury that it need not
    concern itself with the possibility of selective prosecution or
    what the witnesses have be promised in return for their
    testimony. See, e.g., 
    Thomas, 998 F.2d at 1205
    . If, as the
    majority contends, juries comprehend and follow limiting
    instructions such as those given by the District Court in
    this case, surely the better approach, and the one most
    consistent with Third Circuit jurisprudence, is to exclude
    Bonjo and Martin's guilty pleas and to instruct the jury
    members that they should concern themselves only with
    the guilt or innocence of defendants and not with the
    possibility of selective prosecution or the involvement of any
    other persons in any alleged scheme. 
    See supra
    , Majority
    Opinion at 17-18, note 13; 
    Thomas, 998 F.2d at 1205
    ; cf.
    Spencer v. Texas, 
    365 U.S. 554
    , 562-63 (1967) ("[T]his type
    of prejudicial effect is acknowledged to inhere in criminal
    practice, but it is justified on the grounds that . . . the jury
    is expected to follow instructions in limiting this evidence to
    its proper function."). Instead of following our holding in
    Thomas, the majority relies on precedent in other circuits,
    citing one case from the Fifth Circuit and one case from the
    Eleventh Circuit, to support its conclusion that Bonjo and
    Martin's guilty pleas are presumptively admissible. See
    Majority Opinion at 12.11 Ultimately, the majority's
    conclusion that Federal Rule of Evidence 403 "creates a
    presumption of admissibility" with respect to an alleged
    accomplice's guilty plea, a conclusion that is crucial to the
    majority's holding, is unsupported by Third Circuit
    precedent.12
    _________________________________________________________________
    11. The Eleventh Circuit case that the majority cites, Hendrix v.
    Raybestos-Manhattan, Inc., 
    776 F.2d 1492
    (11th Cir. 1985), is a civil tort
    case. Arguably, there exists a heightened concern associated with the
    "danger of unfair prejudice" in the context of a criminal case.
    12. The majority attempts to draw support for its holding from a recent
    Supreme Court case, United States v. Old Chief , 
    519 U.S. 172
    (1997). In
    Old Chief, the Supreme Court held that a trial court abuses its discretion
    when, in a prosecution pursuant to 18 U.S.C. S 922(g)(1) for possession
    of a handgun by a convicted felon, it admits into evidence the name or
    nature of the defendant's prior conviction despite the defendant's offer
    to
    stipulate to his status as a felon under section 922(g)(1). See 
    id. at 190-
    91. While the issue addressed in Old Chief is not entirely unrelated to
    the issue presented in this case, a careful reading of Old Chief confirms
    that it provides no support to either the majority or the dissent in this
    case.
    23
    VI.
    Although the District Court abused its discretion by
    admitting into evidence Bonjo and Martin's guilty pleas, I
    must also consider whether its evidentiary ruling amounts
    to harmless error. See, e.g., United States v. 
    Werme, 939 F.2d at 111
    ("We also conclude that it was harmless error
    to introduce the [witnesses'] guilty pleas."). An error at trial
    is harmless if an appellate court concludes that there is a
    "high probability" that the error did not affect the
    defendant's substantial rights. 
    Id. at 116-17.
    Phrased
    differently, an appellate court must have "a sure conviction
    that the error did not prejudice the defendant, but need not
    disprove every reasonably possibility of prejudice" to
    conclude that the error was harmless. United States v.
    Jannotti, 
    729 F.2d 213
    , 219-20 (3d Cir. 1984).
    Reviewing the record, it is clear that the District Court's
    erroneous evidentiary ruling was not harmless error. Of the
    thirty-nine counts that the defendants were charged with,
    they were acquitted on thirty-eight counts and were
    convicted on only one count, the count to which
    government witness Judy Blum Bonjo pleaded guilty.
    Further suggesting the likelihood of prejudice, the count on
    which the defendants were convicted involved a patient
    named Mildred Hynes, but Mildred Hynes was involved in
    four other counts on which the defendants were acquitted.
    Lastly, and perhaps most importantly, discarding Bonjo's
    and Martin's guilty pleas, the evidence against the
    defendants on Counts Two through Thirty-Nine was
    virtually identical to the evidence presented on the single
    count which the defendants were convicted. In light of
    these facts, I believe that the error here could not be
    harmless.
    VII.
    For the above reasons, I would reverse the defendants'
    convictions and remand the case to the District Court for a
    new trial.
    24
    BECKER, Chief Judge, dissenting:
    I am in full agreement with the reasoning and conclusion
    expressed by the principal dissent in this case--which
    would hold that the District Court erred in admitting
    evidence that the defendants' co-conspirators had entered
    guilty pleas for their respective roles in the underlying
    health-care fraud conspiracy--except insofar as that
    opinion disclaims reliance on Old Chief v. United States,
    
    519 U.S. 172
    (1997). See Dissent at 29 n.12 (Roth, J.). I am
    of the opinion that Old Chief strongly supports the
    defendants' position, and write separately to explain that
    view.
    I read Old Chief as standing for three important
    propositions: First, it makes clear that defense stipulations,
    such as the assurances offered by the defendants in this
    case, are acceptable, if not favored or required, in certain
    limited circumstances. See Old 
    Chief, 519 U.S. at 190-92
    .
    Second, it holds that the government's general prerogative
    to prosecute its case as it sees fit must necessarily yield to
    the dictates of the Federal Rules of Evidence. See 
    id. at 191.
    Third, it tracks the advisory committee notes to the
    Federal Rules of Evidence, and confirms that proffered
    evidence must not be analyzed as an island to itself (as the
    majority seems to do, here), but rather, compared to the
    availability of other means of proof on the same point. See
    
    id. at 184.
    Against this background, I believe that the case
    for allowing a stipulation in this case is even stronger than
    it was in Old Chief.
    In Old Chief, the defendant, charged with being a felon in
    possession of a firearm, had offered to stipulate to an
    element of the offense with which he was charged: having
    a prior felony conviction. The government refused to accept
    the offer, and over the defendant's objection, it introduced
    evidence regarding the name and nature of the defendant's
    underlying felony conviction. The Supreme Court held that
    the district court had abused its discretion in admitting the
    evidence of the underlying conviction. The Court held that
    the defendant's stipulation should have been received and
    that the government's introduction of evidence should have
    been limited, notwithstanding the government's general
    prerogative to choose its own evidence. 
    See 519 U.S. at 1
    190. The Court reasoned that it was proper to allow such
    a stipulation because the evidence regarding the name and
    nature of the prior felony conviction (assault causing
    serious bodily injury) failed the Rule 403 balancing test.
    Although the name and nature of the offense were
    certainly relevant to prove that the defendant had been
    convicted of a felony, see 
    id. at 178-79,
    the defendant's
    offered stipulation was more probative evidence--in fact, it
    was conclusive evidence--that the element was established.
    See 
    id. at 186,
    190. The evidence regarding the name of the
    offense and the nature of the crime was therefore rendered
    surplusage, as it was less conclusive proof of the element,
    see 
    id. at 186,
    and as it was neither necessary to help the
    government create a cohesive narrative about the crime
    charged, see 
    id. 190-92, nor
    "proper nourishment for the
    jurors' sense of obligation to vindicate the public interest,"
    
    id. at 190.
    The evidence regarding the name of the offense and the
    nature of the crime was also problematic because it posed
    a greater risk of undue prejudice than did the stipulation
    and an accompanying jury instruction. See 
    id. at 191-92.
    Evidence of the prior conviction could be used by the jury
    to draw an improper character inference or could lead the
    jury to believe that the defendant was a bad person,
    deserving of punishment whether he was guilty or not. See
    
    id. at 181.
    Therefore, the Court held that the defendant's
    offered stipulation should have been admitted, and the jury
    appropriately instructed on this issue. See 
    id. at 192.
    Here, the defendants offered to stipulate to a collateral
    matter--the content of their cross-examination--rather
    than an element of the offense that the government had the
    burden to prove beyond a reasonable doubt. The
    defendants promised that they would not assert a selective
    prosecution defense, and that they would not impeach the
    co-conspirators on the ground that they were biased
    because they had entered guilty pleas. The government has
    argued that it had the right to introduce evidence of the
    guilty pleas, even though the defendants promised not to
    pursue these lines of cross-examination, because jurors
    might independently reach the conclusion that the
    government had engaged in selective prosecution or that
    2
    the co-conspirators were biased and were unduly shifting
    blame to the defendants.
    The evidence that the government proffered--the co-
    conspirators' guilty pleas--was surely relevant as tending to
    allay these juror concerns. See Old 
    Chief, 519 U.S. at 188
    -
    89. But, given the context of the case, and when compared
    to alternative means of addressing those concerns, the
    government's introduction of the guilty pleas, as with the
    government proffer in Old Chief, fails the Rule 403
    balancing test. Once the defendants offered their
    stipulation, the probative value of the guilty pleas was
    greatly reduced: They no longer affirmatively rebutted a
    selective prosecution defense, and they no longer could be
    used to dampen subsequent attacks on credibility, as those
    attacks were no longer coming.
    Moreover, the guilty pleas were not a necessary part of
    the "coherent narrative" of the case, a factor that would
    normally militate in favor of the government's position. Old
    
    Chief, 502 U.S. at 192
    . United States v. Toner's general rule
    makes clear that co-conspirators' guilty pleas are normally
    inadmissible, see 
    173 F.2d 140
    , 142 (3d Cir. 1949); hence
    it follows that such evidence need not necessarily be part of
    the government's case in chief. Given the defendants'
    stipulation, the guilty pleas' only probative force was their
    tendency to allay hypothesized suspicions in the minds of
    the jurors about why the government had chosen to
    prosecute the defendants, and about the credibility of
    witnesses who had participated in criminal activity with the
    defendants, but were not facing prosecution.
    As Judge Roth ably demonstrates, the danger of unfair
    prejudice inherent in this evidence is great. The jurors
    could infer from the co-conspirators' guilty pleas that the
    defendants must also be guilty if their co-conspirators were
    willing to plead guilty to such crimes. As in Old Chief,
    where the fear was that the name and nature of the
    defendant's underlying felony conviction could mislead or
    over-persuade jurors by "lur[ing]" them to engage in a
    "sequence of bad character reasoning," Old 
    Chief, 519 U.S. at 185
    , the evidence of the co-conspirators' guilty pleas
    carried with it the potential to deprive the defendants of
    3
    their right to "stand or fall with the proof of the charge
    made against him," 
    Toner, 173 F.2d at 142
    .
    When compared to the alternative way in which the
    jurors' suspicions about co-conspirators' guilty pleas could
    have been allayed, it is clear that, as in Old Chief, the
    defendants' stipulation should have been accepted. As
    Judge Roth points out, the District Court could have
    instructed the jury that it should not concern itself with
    selective prosecution or what the co-conspirators were
    promised in return for their testimony. Instead, the District
    Court allowed the pleas to come into evidence and then
    gave a "Toner instruction" admonishing the jurors that they
    could not infer from the co-conspirators' guilty pleas that
    the defendants were also guilty.
    When one compares the probative value and danger of
    unfair prejudice inherent in these two scenarios, the former
    far better comports with the dictates of Rule 403 and the
    Court's admonitions in Old Chief. Judge Roth's suggested
    mode of presentation takes less time and is more direct. In
    her suggested mode of presentation, the judge makes
    definitively clear to the jury that selective prosecution and
    claims of bias are not at issue. Under Judge Roth's theory,
    the danger of the impermissible Toner inference is avoided
    because the guilty pleas are not introduced. Lastly, and
    perhaps most importantly, this mode of presentation does
    not interfere with the government's ability to present a
    "coherent narrative" regarding its case. Old 
    Chief, 502 U.S. at 192
    . If anything, it forecloses the possibility that the jury
    will focus on a tangential and unimportant parts of the
    criminal "plot," and it does so without depriving the jury of
    facts crucial to its understanding of the defendants'
    criminal conspiracy. The defendants' co-conspirators
    testified at length regarding the defendants' myriad acts of
    health care fraud; understanding the means by which the
    defendants' allegedly defrauded the government was in no
    way contingent upon the knowledge that the defendants'
    co-conspirators pled guilty--they testified that they had
    witnessed these crimes first hand.
    In contrast, the mode of presentation endorsed by the
    majority is far more circuitous and confusing because it
    addresses only a potential concern the jurors may have. The
    4
    fact that the government elicits testimony regarding the
    guilty pleas does not mean that the jury will not conclude
    that selective prosecution or blame shifting were at issue.
    Additionally, the impermissible Toner inference could still
    be made, notwithstanding the instruction that jurors must
    not draw the inference.
    The majority attempts to bolster its position by stating
    that the defendants' offer "to refrain from affirmatively
    challenging [their co-conspirators'] credibility did not, and
    could not, carry the same probative value on the issue of
    witness credibility as the introduction of [their] pleas."
    Majority at 16. To me, at least, this argument makes no
    sense. If, complying with their offered stipulation, the
    defendants do not challenge their co-conspirators'
    credibility and the District Court instructs the jury not to
    infer that the co-conspirators are biased, their credibility on
    this point is unimpeached. There is no need for evidence,
    probative or not, on this point. The majority, instead, would
    have the government bolster the co-conspirators' credibility
    before it is challenged with probative evidence--in
    contradiction to the admonitions in Rule 608, as Judge
    Roth points out--and then invite the defendants to attack
    the witnesses' credibility on this issue. This takes far more
    time, is more likely to confuse the jury, and puts at issue
    a point, tangential to the trial, when it clearly need not be,
    especially when it carries with it the twin dangers of unfair
    prejudice. The Federal Rules of Evidence are grounded in
    truth, economy, and fairness, see Fed. R. Evid. 102; the
    majority's approach seems to ignore these aspirations.
    As in Old Chief, rather than present the jury with
    potentially unfairly prejudicial evidence and then instruct
    against an improper inference, the correct thing to do in
    this case was to accept the defendants' stipulation and then
    to instruct the jury as to how to deal with the stipulation
    properly. In Old Chief, that meant making sure that the
    jury understood what the stipulation meant: that the
    government had definitively satisfied the felony status
    element in its felon-in-possession-of-a-firearm prosecution.
    Here, it should have meant instructing the jury that the
    defendants would not be asserting a selective prosecution
    defense or that the co-conspirator witnesses were
    5
    attempting to receive a sweetheart deal by shifting blame to
    the defendants. In not proceeding in this manner, I agree
    with my fellow dissenters' conclusion that the District
    Court, as did the district court in Old Chief , abused its
    discretion.
    6
    SLOVITER, Circuit Judge, dissenting.
    I join Judge Roth's persuasive dissent. I write separately
    because I joined the opinion in United States v. Gaev, 
    24 F.3d 473
    (3d Cir. 1994), an opinion on which the majority
    relies and with which Judge Roth takes issue.
    As the majority correctly notes, our precedent on the
    issue of the admissibility of a witnesses's guilty plea does
    not always follow a consistent line. The en banc procedure
    provides us with a valuable opportunity to reconsider our
    positions on important issues such as that presented here.
    I begin with the proposition that the Federal Rules of
    Evidence do not provide a hard and fast rule covering the
    situation before us today. Instead, the question of whether
    to admit evidence of a co-conspirator witness's guilty plea
    in the trial of his or her alleged confederate must be
    subjected to the balancing required by Fed. R. Evid. 403. In
    Gaev, we emphasized that the "standard remains that of
    Federal Rule of Evidence Procedure 403" and recognized
    that "[t]here may . . . be cases where the inference of guilt
    from the co-conspirator's plea agreement is sufficiently
    strong that even limiting instructions will not effectively
    contain it." 
    Gaev, 24 F.3d at 478
    .
    I dissent from the majority's position because I view its
    analysis as permitting the government to introduce
    evidence of a co-conspirator witness's guilty plea in all
    cases, as long as the district court provides a curative
    instruction to the jury. This is inconsistent with the
    principle established in this circuit that a witness's guilty
    plea cannot be used as evidence of the defendant's guilt.
    See United States v. Cohen, 
    171 F.3d 796
    , 801 (3d Cir.
    1999); United States v. Gaev, 
    24 F.3d 473
    , 476 (3d Cir.
    1994); United States v. Thomas, 
    998 F.2d 1202
    , 1206 (3d
    Cir. 1993); Government of the Virgin Islands v. Mujahid, 
    990 F.2d 111
    , 115 (3d Cir. 1993); United States v. Werme, 
    939 F.2d 108
    , 113 (3d Cir. 1991); United States v. Toner, 
    173 F.2d 140
    , 142 (3d Cir. 1949). The majority's holding that a
    guilty plea is admissible to permit the jury to assess the
    credibility of the witness, even in the absence of an attack
    on the witness's credibility, or to dispel jury concern about
    selective prosecution, even if the defendant has not so
    1
    contended, transmutes a case-by-case analysis under Fed.
    R. Evid. 403 into a general rule of admissibility. I see no
    justification for such a rule.1
    _________________________________________________________________
    1. It is significant that defendants here did not contest the acts on
    which
    the prosecution is based, whereas in Gaev the defendant "challenged
    critical aspects of Gaev's participation in the activities that formed the
    basis of Gaev's conviction."

    RENDELL, Circuit Judge, dissenting:
    I am pleased to join in my colleague's excellent dissenting
    opinion, and I write separately only to go one step further
    than she did with respect to the application of the Rule 403
    balancing test. I submit that the probative value of a guilty
    plea is not just negligible, but nil. At the same time, given
    the unique setting of this case, there is not merely a danger
    of prejudice, but the prejudice is obvious and real.
    The majority seems to be saying that relevance is equated
    to whatever the jury might like to know, which I believe is
    precisely how the District Court viewed the issue. How is
    our ruling any different from letting the prosecution
    introduce a witness's Boy Scout badges and lie detector
    results on direct examination because a jury may wonder if
    the witness is telling the truth? Why should we concern
    ourselves that the jury may wonder about credibility and
    selective prosecution? What relevance do they have to the
    government's case? I submit that they have absolutely
    none.
    Even if credibility and selective prosecution were
    somehow relevant to the government's case, the
    prosecution could satisfy the jury's curiosity as to these
    issues just as easily by engaging in the following exchange
    with the witness:
    Question: Are you being prosecuted by the
    government?
    (Response: Yes.)
    Question: Have you admitted that you were involved
    in the events about which you are
    testifying?
    (Response: Yes.)
    This line of questioning addresses credibility and
    selective prosecution while it leaves open the crucial
    question of guilt of the offense charged, which is the most
    dangerous aspect of the admissibility of a guilty plea in this
    unique setting. Under the facts of this case, the defendants
    do not deny that they participated in the same conduct as
    the witness. They contend, however, that this conduct was
    1
    not a crime. When another participant testifies that she
    admitted her guilt of the offense, she not only tells the jury
    that "what we did is a crime," but she also says "I owned
    up to it; why won't the defendants? Why are they putting
    you through a trial when we are guilty?" The probable
    prejudice in a case such as this is immense and far
    outweighs the relevance, especially because the relevance,
    I submit, is illusory.
