dissenting:
The majority elevates a harmless variance to a constructive amendment of the indict*715ment. It then announces that a constructive amendment mandates reversal of a criminal conviction per se, even where there is no objection below, thereby embracing a per se rule of plain error. On this basis, the majority orders Floresca’s conviction under 18 U.S.C. § 1512 reversed.
The majority’s reasoning is flawed in several respects. First, a proper analysis confirms that the error in this case is not a constructive amendment of the indictment, but a variance, and a harmless variance at that. Second, even assuming that there was a constructive amendment below, the majority’s application of a per se plain error rule flies in the face of recent relevant Supreme Court precedent, particularly United States v. Olano, — U.S.—, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993). Application of the proper plain error standard dictates that the conviction below be affirmed. I, therefore, respectfully dissent.
I.
The statute at issue in this case, 18 U.S.C. § 1512(b), provides, in pertinent part:
Whoever knowingly uses intimidation or physical force, threatens or corruptly persuades another person, or attempts to do so, or engages in misleading conduct toward another person, with intent to—
(1) influence, delay or prevent the testimony of any person in an official proceeding; [or to]
* * * * * *
(3) hinder, delay, or prevent the communication to a law enforcement officer or judge of the United States of information relating to the commission or possible commission of a Federal offense or a violation of conditions of probation, parole, or release pending judicial proceedings;
shall be fined not more than $250,000 or imprisoned not more than ten years, or both.
18 U.S.C. § 1512(b)(1), (3).
Count nine of the indictment against Floresca is entitled: ‘WITNESS TAMPERING [TITLE 18, U.S.C. SECTION 1512]”. J.A. 35. While paragraph D of count nine charges Floresca with “engag[ing] in a continuing course of conduct to threaten, intimidate, and mislead [Lopez] with intent to influence, delay, and prevent the testimony of [Lopez] in an official proceeding,” J.A. 35, conduct prohibited under section 1512(b)(1); paragraph F of the count charges that, as “a part of this continuing course of conduct ... defendant JOSE P. FLORESCA told [Lopez] to falsely tell [his] attorney and the authorities that defendant FLORESCA never gave [Lopez] the prescription for thirty (30) dosage units of phentermine, also known as ‘Fastin’ described in Count One of the September 5, 1991 indictment and in paragraphs J, K and L of Count One of this present indictment,” J.A. 36 (emphasis added), conduct prohibited under section 1512(b)(3). Thus, the indictment gave notice to Floresca that the evidence would show violations of 18 U.S.C. § 1512(b)(1) and (b)(3). However, count nine concludes by stating that Floresca had conducted the activities alleged therein “ALL IN VIOLATION OF TITLE 18, UNITED STATES CODE,' § 1512(b)(1).” J.A. 37.
The evidence presented at trial on the subject of Floresca’s intimidation of Lopez consisted entirely of the testimony of Lopez, who was indicted with Floresca but entered into a plea bargain with the government in return for his testimony. Lopez testified that, following his indictment, but prior to his discussing a plea bargain with the government, “[Floresca] started to argue with me about my legality coming here to the United States, that I’m illegal coming in the states and my marriage is bad. [sic]” J.A. 244. Lopez further testified that, after he had consulted with his lawyer,
[Floresca] started telling me these things that I was illegal. And when I argue with him, he started, he started to talk about he got a lot of friends in Manila airport and he can call them and order them to do something with a person and he knows my son is coming here [from the Philippines], [sic]
J.A. 244-45. Thereafter Lopez’s lawyer instructed Lopez to inform Floresca that he could no longer discuss the ease with him. *716Lopez testified that, when he told Floresca this, “[Floresca] tried to harass me; tell me that he goes to jail, I go to jail, [sic]” J.A. 245.
Lopez then entered into a plea bargain with the government and was wired with a taping device. Lopez testified that Floresca never again orally threatened him, but did testify:
Q Did Dr. Floresca ever communicate with you about this case other than orally, other than by mouth?
A One time when I wear this tape, he write on a small paper a, toilet paper or, paper towel, paper towel.
Q Did you see what he wrote on there? A Yes, sir.
Q What did he write?
A “Don’t plea bargain. If you plea bargain, you are in their mercy.”
J.A. 247.1 .
On cross-examination, Floresca’s attorney, in an attempt to show that Floresca’s statements were not threats, established that Lopez’s marriage was legal and that Lopez is a citizen of the United States. He also established that Lopez had captured none of Floresca’s threats on tape, and that, because Floresca had not allowed him to keep the paper upon which the written threat had appeared, Lopez could not substantiate this claim.
Although the statutory provision cited in the. indictment, section 1512(b)(1), prohibits threats that interfere with testimony at an official proceeding, the district court, without objection, charged the jury that it should find Lopez guilty if Floresca made threats to interfere with Lopez’s communications with law enforcement officials.2 The majority concludes that the district court’s error, which the majority describes as a constructive amendment of the indictment, was plain error that entitles Floresca to reversal of his conviction for violation of section 1512.
II.
Contrary to the conclusion drawn by the majority, there was no constructive amendment of the indictment in this case.
Constructive amendments and variances both arise from similar situations: where the facts or underlying theory of criminality alleged in the indictment vary, as a result of the introduction of evidence, argument by the government, or the district court’s jury instructions, from the facts or underlying theory of criminality established at trial. A constructive amendment occurs where, as a result, “the possible bases for conviction” are broadened beyond the bases appearing in the indictment. United States v. Miller, 471 U.S. 130, 138, 105 S.Ct. 1811, 1816, 85 L.Ed.2d 99 (1985). A variance, by contrast, occurs where a broadening of the bases for conviction does not result. See id. at 145, 105 S.Ct. at 1819-20.3
A broadening of the bases for conviction occurs where the defendant is convicted of a crime not passed upon by a grand jury. See id. at 138-39, 105 S.Ct. at 1815-17; Stirone v. United States, 361 U.S. 212, 80 S.Ct. 270, 4 L.Ed.2d 252 (1960). Under this definition, it is clear that, where the elements of the crime for which a defendant is ultimately convicted are set out in the indictment and where the evidence at trial establishes only facts that were alleged in the indictment, there is no broadening of the bases for conviction and, consequently, the only error that may arise is a variance. See United States v. Schnabel, 939 F.2d 197, 203 (4th Cir.1991) (“Construc*717tive amendment consists of alteration of an indictment by (1) presentation of evidence, and (2) jury instructions^] both of which work to change the elements of the offense charged, such that the defendant is actually convicted of a crime other than that charged in the indictment.”); United States v. Hathaway, 798 F.2d 902, 910 (6th Cir.1986) (“A constructive amendment occurs when the terms of an indictment are in effect altered by the presentation of evidence and jury instructions which so modify essential elements of the offense charged that there is a substantial likelihood that the defendant may have been convicted of an offense other than that charged in the indictment.”). Thus, as one leading treatise has commented, the classification of constructive amendments “has been limited to cases in which the prosecution presents a complex of facts distinctly different from that set forth in the charging instrument.” 3 Charles Alan Wright, Federal Practice and Procedure § 516, at 27 (2d ed.1982) (footnotes omitted). See United States v. Massuet, 851 F.2d 111, 116 (4th Cir.1988) (“In contrast with the situation disclosed by Stirone, the government did not attempt to offer any evidence in support of any other charge”), cert. denied, 488 U.S. 1005, 109 S.Ct. 785, 102 L.Ed.2d 776 (1989); Jackson v. United States, 359 F.2d 260, 263 (D.C.Cir.) (distinguishing Stirone from the ease then at bar on the basis that, “[i]n Stirone the prosecution was relying at trial on a complex of facts distinctly different from that which the grand jury set forth in the indictment,” while, “in the case before us, there is a single set of facts”), cert. denied, 385 U.S. 877, 87 S.Ct. 157, 17 L.Ed.2d 104 (1966); accord United States v. Knuckles, 581 F.2d 305, 312 (2d Cir.), cert. denied, 439 U.S. 986, 99 S.Ct. 581, 58 L.Ed.2d 659 (1978).
We need not further define the contours of the boundary between variances and constructive amendments for the case at bar fits squarely into the situation described above. Floresca’s conviction can be seen to lie under section 1512(b)(1) or section 1512(b)(3). With respect to section 1512(b)(1), the indictment specifically cited that provision, set out the elements of that provision, and alleged facts meeting each element of the provision and therefore constituting a violation of that provision. With respect to section 1512(b)(3), count nine of the indictment charged that “defendant JOSE P. FLORESCA told [Lopez] to falsely tell [his] attorney and the authorities that defendant FLORESCA never gave [Lopez] the prescription for thirty (30) dosage units of phentermine,” J.A. 36 (emphasis added). Thus, the indictment set out the elements of section 1512(b)(3) and alleged facts meeting the elements of that provision and therefore constituting a violation of that provision.
The only arguable error was that the indictment contained no citation to section 1512(b)(3). However, an indictment that provides an incorrect or incomplete citation creates merely a variance, which, absent prejudice, is harmless. As we explained in United States v. Duncan, 598 F.2d 839, 854 n. 11 (4th Cir.), cert. denied, 444 U.S. 871, 100 S.Ct. 148, 62 L.Ed.2d 96 (1979),
[T]he citation of a statutory provision in an indictment is solely for the benefit of ... defendants; its inclusion is intended to better apprise the defendant of the charges against him without danger to the prosecution. Fed.R.Crim.P. 7, Notes of the Advisory Committee. The rule has long been that a conviction may be sustained on the basis of a statute other than that cited in the indictment. E.g., Williams v. United States, 168 U.S. 382, 389, 18 S.Ct. 92 [94-95], 42 L.Ed. 509 (1897). Miscitation of the statute is harmful error only if prejudice to the defendant can be shown. Fed.R.Crim.P. 7(c)(3).
Accord United States v. Massuet, supra, 851 F.2d at 116 (“If the indictment had included the exact language which it did but cited section 841(a)(1) instead of section 959(b)(2) or even no statute at all, it would have been valid and any challenge against it would have failed.”). There was, then, no constructive amendment of the indictment whether Floresca was convicted under section 1512(b)(1) or section 1512(b)(3).4
*718The majority contends that this case is “indistinguishable” from Moore v. United States, 512 F.2d 1255 (4th Cir.1975). Ante, at 710. An examination of Moore belies this contention. In Moore, the defendant was indicted for violating 26 U.S.C. § 5861(d). That section provides: “It shall be unlawful for any person ... to receive or possess a firearm which is not registered to him in the National Firearms Registration and Transfer Record....” Included in the definition of the term “firearm,” found at 26 U.S.C. § 5845(a), are any “shotgun having a barrel or barrels of less than 18 inches in length,” id. § 5845(a)(1), and “any other weapon, as defined in subsection (e) [of section 5845],” id. § 5845(a)(5).
The indictment specifically charged Moore with “ ‘unlawfully and knowingly possess[ing] a firearm, that is, a sawed-off 12-gauge shotgun ... which was not registered ... as required by ... § 5861(d)_’ ” Id at 1257 (Widener, J., dissenting) (emphasis added). “The weapon introduced at trial, however, was certified to be a ‘[flirearm made by inserting a 11 inch piece of galvanized pipe into a barrel of flare gun and welding same with solder. The pipe is of the size that will chamber a 12 gauge shotgun shell.’ [sic]” Id. at 1256. This weapon is not a “shotgun” meeting the specifications of section 5845(a)(1), but falls within section 5845(e)’s definition of “any other weapon.” The district court instructed the jury that “any other weapon,” as defined in section 5845(e), constituted a “firearm.” Id. at 1257 (Widener, J., dissenting).
In short, the problem in Moore was that the evidence at trial established that the firearm possessed by Moore was distinct from the firearm alleged to have been possessed by Moore in the indictment. As a result, the elements underlying the crime charged and the relevant facts as alleged in the indictment differed from those introduced at trial and upon which Moore was convicted. While, as described above, a constructive amendment will often arise where, as in Moore, facts different from those alleged in the indictment are introduced at trial, the majority in Moore was able to satisfy itself that the bases of conviction were not broadened by viewing the crime with which Moore had been charged as identical to the crime of which he was convicted. Because the majority found that Moore “was in no way prejudiced by the variance,” id., it affirmed Moore’s conviction.
A comparison of Moore and the instant case reveals that the error herein is far less egregious than was the error in Moore: while, in Moore, the elements of the crime for which Moore was indicted varied from those of the crime for which he was convicted and facts entirely distinct from those presented in the indictment were introduced into evidence at trial, here, as noted above, the indictment set out the elements required under both paragraphs and the evidence at trial did not extend beyond the facts alleged in the indictment.5 Yet, we found the error in *719Moore to be merely a variance; indeed, Moore has recently been described as “[a] classic example of a variance ease.” Wilson v. Lindler, 995 F.2d 1256, 1261 (4th Cir.1993) ((opinion of Hamilton, J.) (“adopt[ed]” as the opinion of the dissenting members of the en banc court in Wilson v. Lindler, 8 F.3d 173, 175 (4th Cir.1993), cert. denied, — U.S. —, 114 S.Ct. 1101, 127 L.Ed.2d 414 (1994))). If, indeed, Moore is a variance ease, then, a fortiori, so is the one now before us.
Recognizing this, the majority can only render this “dissent’s reliance on Moore ... misplaced” by overruling that case. Ante, at 710. Of course, even if Moore is aptly seen as a constructive amendment ease, that would not mean that the error herein was also a constructive amendment. Because, again, the error in Moore was more egregious, it is entirely conceivable and, indeed, logical that the error in Moore was a constructive amendment while the error herein is a variance.6
I therefore conclude that the error in this case was a variance.
III.
A variance is fatal only if it is in some way prejudicial to the accused. See United States v. Brewer, 1 F.3d 1430, 1437 (4th Cir.1993); United States v. Morrow, 925 F.2d 779, 781 (4th Cir.1991). Otherwise, the *720variance, though error, is harmless. See Brewer, 1 F.3d at 1437; Morrow, 925 F.2d at 781-82.
Because the indictment here set out the elements of both paragraphs and charged facts amounting to violations of both paragraphs, it is clear that the variance in this case did not unfairly surprise Floresca. Floresca certainly had notice of the charges against him adequate enough to allow him to prepare a defense.
Further, the facts of this case indicate that Floresca cannot demonstrate prejudice, ie., that the error affected the outcome of the trial. The jury charge differs from the charge cited in the indictment only in that the charge given to the jury allowed the jury to convict Floresca under paragraph (3), while the indictment, though it charged the elements of both paragraphs, provided a citation only to paragraph (1). It is clear that Floresca cannot claim surprise resulting from the omitted citation.
Moreover, even if, as seems highly doubtful, Floresca was somehow confused by the omission of a citation to paragraph (3), that is of no moment, for the difference between the two paragraphs was completely immaterial in this case. The only person with whom the government charged Floresca with interfering was Lopez, and the evidence the government presented was that Floresca had threatened Lopez with the general intent of keeping him from cooperating with the government. Lopez testified that Floresca told him that, by cooperating with the government against Floresca, Lopez might be placed in prison or be deported. Floresca enhanced these threats by telling Lopez, according to Lopez’s testimony, that, by entering into a plea bargain, he would be at the mercy of the government. Lopez also testified that Floresca made thinly-veiled threats against his son.
Based on this evidence, after the judge instructed the jury that it could find Floresca guilty of interfering with a person who might relate to a law enforcement official knowledge of commission of a federal crime, the jury found Floresca guilty. Floresca’s only response to this evidence was to assert that his statements were not really threats. It is inconceivable that the jury, on the evidence presented, would have convicted Floresca for interfering with Lopez’s communication to law enforcement authorities, but acquitted Floresca of interfering with Lopez’s testimony at trial. Nor can Floresca point to any evidence which he would have presented to defend himself against the charge of interfering with Lopez’s communication to law enforcement authorities which he did not present to defend himself against the charge of interfering with Lopez’s trial testimony. Floresca, thus, cannot show that he was prejudiced by the district court’s error and, as a result, the variance in this case was harmless.
IV.
Even accepting the majority’s characterization of the error as a constructive amendment, I disagree with the majority’s result. Under United States v. Olano, — U.S.—, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993), to demonstrate plain error under Rule 52(b), a criminal defendant must demonstrate (1) error (2) that is plain and (3) that affects substantial rights. If such a showing is made, then the court of appeals has discretion to exercise its remedial power. Exercise of this discretion turns upon a determination of whether the error seriously affects the fairness, integrity or public reputation of judicial proceedings.
Despite Olano1 s clear directive, the majority claims that “[i]t is an open question as to whether the absence of an objection requires further analysis when the alleged error goes to the heart of the entire judicial process.” Ante, at 712. According to the majority, “it is by no means clear that we should” apply Olano here. Ante, at 712. The majority’s position in this regard is absolutely devoid of support.7
The opinion in Olano presents the Supreme Court’s interpretation of Federal Rule of Criminal Procedure 52(b). Rule 52(b) confers upon the courts of appeals the “limited power,” — U.S. at—, 113 S.Ct. at 1776, *721in appropriate cases, to reverse criminal convictions based upon errors which, though plain, were forfeited by the criminal defendant below. Nothing in the language of Rule 52(b) indicates that the rule might not apply to all forfeited errors in criminal cases. It is not surprising, then, that the majority makes no claim that Rule 52(b) does not apply here. Nor does the majority claim that some other statutory provision or rule provides power, supplemental to that provided by Rule 52(b), to correct forfeited errors. Indeed, it is clear and uncontested that Rule 52(b) governs here.
The Supreme Court in Olano analyzed the language of Rule 52(b) and developed a practical test therefrom for courts to apply in determining whether there is reversible plain error. The very thrust of Olano was the development of such a test which would be applicable in all criminal cases in which a criminal defendant, on appeal, asserts a claim of error which was forfeited below. There is simply no basis for the majority’s speculation that the Supreme Court might have contemplated that the test formulated in Olano not apply to all cases in which Rule 52(b) is implicated.8
It comes as no surprise then, except perhaps to the majority, that the First and District of Columbia Circuits have concluded that Olano controls wherever there is a forfeited error in a criminal case, even where the error in question is not susceptible to harmless error analysis. See United States v. Washington, 12 F.3d 1128, 1138 (D.C.Cir.1994) (applying Olano analysis to a forfeited claim that a constitutionally deficient reasonable doubt instruction had been delivered; the delivery of such an instruction was found to be per se harmful in Sullivan v. Louisiana, — U.S. —, 113 S.Ct. 2078, 124 L.Ed.2d 182 (1993)9), cert. denied, — U.S. —, 115 S.Ct. 98, — L.Ed.2d—(1994); United States v. Merlos, 8 F.3d 48 (D.C.Cir.1993) (same), cert. denied, — U.S.—, 114 S.Ct. 1635, 128 L.Ed.2d 358 (1994); United States v. Colon-Pagan, 1 F.3d 80 (1st Cir.1993) (applying full Olano analysis in a constructive amendment case); United States v. Lawton, 995 F.2d 290 (D.C.Cir.1993) (same). See also United States v. Gaudin, 28 F.3d 943, 951-52 (9th Cir.1994) (en banc) (applying Olano analysis in a case where district court’s jury instruction omitted essential element of charged crime, an error which that court of appeals found to be “structural”).
Although the majority is explicit only in its attempt to evade Olano, the fact remains that the result of its musings would be to avoid the impact of a long line of Supreme Court plain error cases predating Olano, as well as the plain language of Rule 52(b) itself.
V.
I conclude, as of course I must, that Rule 52(b), Olano, and, indeed, all Supreme Court plain error cases are binding upon us. When one examines the ramifications of these authorities to the majority’s position, it is readily understood why the majority seeks to evade them. The fact is that Olano and the Supreme Court eases upon which Olano relies are inconsistent with a per se plain error rule. Indeed, Olano itself reversed the Ninth Circuit’s use of a per se plain error rule. See Olano, — U.S. at—, 113 S.Ct. at 1776. And, in United States v. Young, 470 U.S. 1, 16 n. 14, 105 S.Ct. 1038, 1047 n. 14, 84 L.Ed.2d 1 (1985), the Supreme Court explicitly eschewed a per se plain error rule, such as the one propounded by the majority here, stating:
A per se approach to plain-error review is flawed. An error, of course, must be more than obvious or readily apparent in order to trigger appellate review under Federal Rule of Criminal Procedure 52(b). Following decisions such as United States v. Frady, [456 U.S. 152, 102 S.Ct. 1584, 71 L.Ed.2d 816 (1982),] United States v. Socony-Vacuum Oil Co., [310 U.S. 150, 60 *722S.Ct. 811, 84 L.Ed. 1129 (1940) ], and United States v. Atkinson, [297 U.S. 157, 160, 56 S.Ct. 391, 392, 80 L.Ed. 555 (1936),] federal courts have consistently interpreted the plain-error doctrine as requiring an appellate court to find that the claimed error not only seriously affected “substantial rights,” but that it had an unfair prejudicial impact on the jury’s deliberations. Only then would the court be able to conclude that the error undermined the fairness of the trial and contributed to a miscarriage of justice.
VI.
The Supreme Court could not be more unequivocal: “A per se approach to plain-error review is flawed.” Young, 470 U.S. at 16 n. 14, 105 S.Ct. at 1047 n. 14.
Undaunted, the majority purports to follow Olano and, amazingly, finds it entirely consistent with a per se rule. The majority achieves this remarkable result, which, in fight of the foregoing, is logically impossible, by means of reasoning unfamiliar to Rule 52(b) jurisprudence. Indeed, while the form of the majority’s analysis mimics Olano, the substance of its analysis is quite dissimilar from, and is, in large measure, irreconcilable with, the Supreme Court’s clear directive in Olano.
It cannot be disputed that there was error below, of one form or another, and that such error was “plain.” I question, however, whether the error satisfies Olano’s third prong. Moreover, even if it does, it is clear that this is not a case in which we should exercise our discretion to correct the error.
A.
Olano’s third prong requires “that the plain error ‘affec[t] substantial rights.’ This is the same language employed in Rule 52(a), and in most cases it means that the error must have been prejudicial: It must have affected the outcome of the District Court proceedings.” — U.S. at-, 113 S.Ct. at 1777-78.
1.
The majority contends that a determination of prejudice cannot be conducted in this case because “it is ‘utterly meaningless’ to posit that any rational grand jury could or would have indicted Floresca under Paragraph 3, because it is plain that this grand jury did not.” Ante, at-(quoting Sullivan v. Louisiana, — U.S.—,—, 113 S.Ct. 2078, 2082, 124 L.Ed.2d 182 (1993)). The majority, in making this statement, overlooks the fact that the grand jury did indict Floresca for instructing Lopez “to falsely tell [his] attorney and the authorities that defendant FLORESCA never gave [Lopez] the prescription for thirty (30) dosage units of phentermine,” J.A. 36 (emphasis added); this is the very conduct prohibited under paragraph 3.10
It is possible and appropriate, then, to determine whether the outcome of Floresca’s trial was affected by the error in this case. As discussed above, supra, in Section III, the facts of this case establish conclusively that Floresca cannot demonstrate prejudice, i.e., that the error affected the outcome of the trial.
2.
The majority opinion concludes that Ola-no’third prong is met because the error of constructive amendment of an indictment is not susceptible to harmless error analysis. This argument relies upon the use of the nearly identical phrasing “affect substantial rights” in subsections (a) and (b) of Rule 52.11 If an error can never be harmless and there*723fore, under Rule 52(a), always affects substantial rights, then, the argument goes, the error must affect substantial rights under Rule 52(b) and, thus, meets Olano’s third prong.12
Although the structure of Rule 52 may suggest such an interpretation, the Court in Olano left this question open. See — U.S. at-, 113 S.Ct. at 1778 (“There may be a special category of forfeited errors that can be corrected regardless of their effect on the outcome, but this issue need not be addressed. ... Normally, although perhaps not in every case, the defendant must make a specific showing of prejudice to satisfy the ‘affecting substantial rights’ prong of Rule 52(b).” (emphasis added)); id. at-, 113 S.Ct. at 1779 (“Assuming arguendo that certain errors ‘affec[t] substantial rights’ independent of prejudice, the instant violation of Rule 24(c) is not such an error.”). Despite this non-committal language, the majority assumes not only that the Olano Court intended that a showing of prejudice is not required for some class of forfeited errors, but also that the class of errors for which this is the case is the class of errors not susceptible to harmless error analysis. This is, of course, nothing more than speculation on the part of the majority; nothing in Olano lends support to the majority’s musings.13
I would note that, in United States v. Lawton, supra, 995 F.2d 290, the District of Columbia Circuit was faced with a constructive amendment to which no objection had been lodged below. That court did not shirk, as does the majority here, its responsibility under Olano to determine whether the defendant was prejudiced thereby. See 995 F.2d at 294. See also United States v. Gaudin, supra, 28 F.3d at 951-52 (although the Ninth Circuit found the district court’s failure to instruct the jury as to an essential element of the crime charged to be a “structural error” which per se affected substantial rights, the court nevertheless took account of prejudice in its Olano analysis, noting that, had the district court properly instructed the jury, the jury would have been faced with “a serious factual question”).
B.
The majority’s largest error, however, is not its analysis of Olano’s third prong, but its approach to the exercise of discretion required by Olano. Even assuming that the first three prongs of the Olano test are met, the question remains as to whether the error “‘seriously affects the fairness, integrity or public reputation of judicial proceedings,’” Olano, — U.S. at—, 113 S.Ct. at 1779 (quoting United States v. Atkinson, 297 U.S. 157, 160, 56 S.Ct. 391, 392, 80 L.Ed. 555 *724(1936)), so that we should exercise our discretionary remedial power. This question is not to be glossed over. As the Supreme Court explained, “[A] plain error affecting substantial rights does not, without more, satisfy the Atkinson standard, for otherwise the discretion afforded by Rule 52(b) would be illusory.” — U.S. at -, 113 S.Ct. at 1779.
The Supreme Court’s emphasis on the discretion of the court of appeals to exercise its remedial power indicates that this power is equitable. It is clear, then, that, in determining whether to exercise this power, a court must consider the equities of the particular case before it.14 United States v. Childress, 26 F.3d 498, 504 (4th Cir.1994). In exercising our discretionary power, we must bear in mind that Rule 52(b)
authorizes the Courts of Appeals to correct only “particularly egregious errors,” United States v. Frady, 456 U.S. 152, 163, 102 S.Ct. 1584, 1592, 71 L.Ed.2d 816 (1982), those errors that “seriously affect the fairness, integrity or public reputation of judicial proceedings,” United States v. Atkinson, 297 U.S., at 160, 56 S.Ct., at 392. Any unwarranted extension of this exacting definition of plain error would skew the Rule’s “careful balancing of our need to encourage all trial participants to seek a fair and accurate trial the first time around against our insistence that obvious injustice be promptly redressed.” Id. [456 U.S.], at 163, 102 S.Ct., at 1592 (footnote omitted).
United States v. Young, supra, 470 U.S. at 15-16, 105 S.Ct. at 1046.
1.
A determination of whether the error in a given ease is likely, if uneorrected, “seriously [to] affect[ ] the fairness, integrity or public reputation of judicial proceedings” necessarily entails an assessment of prejudice in light of the equities of the case.15 Although a showing of prejudice does not, alone, compel such a conclusion, the absence of prejudice virtually precludes it. See Young, 470 U.S. at 16 n. 14, 105 S.Ct. at 1047 n. 14; supra note 15.
As explained at length in Section III, supra, the district court’s error in this case did *725not in any way prejudice Floresca. Nor is there any indication or suggestion that the. error was in any way the result of deliberate actions on the part of the prosecution or the district court. In short, it is plain that “the fairness, integrity or public reputation of judicial proceedings” would not be “seriously affected” were we to decline to exercise our discretionary remedial power to correct the error in this case.
2.
Concerns of equity and justice do not deter the majority. Extolling technicality over fairness, compare Childress, 26 F.3d at 504 (declining to exercise our Rule 52(b) discretionary power to remedy “a quibbling disagreement with how the district court instructed the jury”), the majority tries to force its per se rule into the Olano analytical model. In effect, the majority asserts that constructive amendments per se “seriously affect the fairness, integrity or public reputation of judicial proceedings.” Despite the fact that such a per se rule is wholly irreconcilable with the language and clear purpose of Supreme Court decisions such as Olano, Young and Frady, supra, 456 U.S. 152, 102 S.Ct. 1584, 71 L.Ed.2d 816 (1982), the majority suggests that subjecting Stirone errors to full Olano review where no objection below has been lodged both is unfair and undermines the integrity of the court system. Neither of these contentions is accurate.
Central to the majority’s position is the proposition that affirmance of the conviction below would emasculate the right to indictment by a grand jury and overrule Stirone. See ante, at 712-14. The majority’s mischar-acterization of the effect of affirming Flores-ca’s section 1512 conviction could not be more gross. Affirming the conviction herein would in no way “depriv[e] ... accused[s] of the protection of the grand jury.” Ante, at 713-14. If an accused timely raises an objection based upon the Fifth Amendment’s Grand Jury clause, the district court should consider and rule upon such objection. In light of Stirone, moreover, where, following timely objection, the district court erroneously fails to grant relief from a true constructive amendment of the indictment, this Court will reverse any conviction obtained below. Where, however, as here, the defendant fails to raise any objection below, the defendant must establish that affirmance of his conviction would “ ‘seriously affect[ ] the fairness, integrity or public reputation of judicial proceedings,’ ” Olano, — U.S. at —, 113 S.Ct. at 1779 (quoting United States v. Atkinson, 297 U.S. at 160, 56 S.Ct. at 392). Such a rule, contrary to the majority’s suggestion, see ante, at 712-14, in no way overrules or even undermines Stirone. See United States v. Thetford, 676 F.2d 170, 180 (5th Cir.1982) (in a plain error ease, distinguishing Stirone on the ground that, in the case under review, “[ujnlike Stirone, ... there was no objection to the jury instruction given” (footnote omitted)),16 cert. denied, 459 *726U.S. 1148, 103 S.Ct. 790, 74 L.Ed.2d 996 (1983); United States v. Coulter, 474 F.2d 1004, 1005 (9th Cir.) (in plain error case, distinguishing Stirone on the ground that “[i]n Stirone an objection was made at trial”), cert. denied, 414 U.S. 833, 94 S.Ct. 172, 38 L.Ed.2d 68 (1973); see also Jackson v. United States, supra, 359 F.2d at 263 (finding no reversible plain error in a similar case, but suggesting that Stirone might govern “if timely objection had-been made”).
With this in mind, I turn to the majority’s specific objections to abstaining from exercising our discretionary 'Rule 52(b) remedial power in all constructive amendment cases. First, the majority asserts that to “depriv[e] an accused of the protection of the grand jury would be ... intolerably unfair.” Ante, at 713-14. This, in the abstract, is true. However, as demonstrated just above, requiring an accused who failed below to raise an objection to a claimed constructive amendment to meet the Olano test does not deprive the accused of the protection of the grand jury. An accused retains below the right to object to the claimed constructive amendment. The burden which he must meet to warrant correction of the error increases17 only by virtue of his failure to voice any such objection below. There is nothing “intolerably unfair” about enforcing the contemporaneous-objection rule.' See Young, 470 U.S. at 15-16, 105 S.Ct. at 1046-47.18
The majority next suggests that affir-mance of the conviction below would under*727mine the integrity of the federal court system by eroding the right to indictment by a grand jury and overruling Stirone. See ante, at 713-14. The discussion above completely discredits the premise underlying this argument and, with it, the argument itself.
Thus, subjecting constructive amendments to which objections were not lodged at the trial level to an Olano analysis in no way undermines the integrity of the court system. Rather, I would suggest, it is the rule adopted by the majority, that certain errors, namely those that are not susceptible to harmless error analysis, are always considered to be reversible plain errors as a matter of law, even where they are not objected to at trial, undermines the court system’s integrity, by encouraging defense counsel to fore-go objecting to such errors at trial. If defense counsel’s client is acquitted, he succeeds; at worst, a conviction results, and his client will be entitled to a retrial as a matter of law. This exceedingly undesirable result undermines the contemporaneous objection rule, see Young, 470 U.S. at 15-16, 105 S.Ct. at 1046-47, and, with it, the integrity and reputation of the court system.
At bottom, the majority overturns Flores-ca’s conviction on a technicality. This, alone, erodes the integrity and public reputation of our court system. Worse, the majority promulgates a per se rule under which such technicalities will, as a matter of law, always triumph over fairness and entitle fortunate defendants to reversal. The deleterious effect of such a rule on the integrity and public reputation of the court system is sure to be even more pronounced.
VII.
The majority elevates the harmless variance in this case to a constructive amendment of the indictment. Then, when the majority, begrudgingly, applies Olano to the error herein, it misconstrues and misapplies the Supreme Court’s opinion; only by its gross mischaracterization of Olano can the majority reach the result it does, a result that truly flies in the face of fairness.
I would affirm the district court’s judgment in all respects.19 I respectfully dissent.
Circuit Judges WILKINSON, WILKINS, NIEMEYER and WILLIAMS join this dissenting opinion.. Accepting this testimony as truthful, Floresca was apparently unaware that Lopez had already entered into a plea bargain.
. The district judge read the text of the statutory provision cited in the indictment, section 1512(b)(1), to the jury, but in her explanation of the elements of the offense charged, instructed only as to section 1512(b)(3).
. The question of whether the error herein was a constructive amendment or a variance looms large because a variance can be viewed as harmless error, see United States v. Brewer, 1 F.3d 1430, 1437 (4th Cir.1993), while a constructive amendment cannot, see Stirone v. United States, 361 U.S. 212, 80 S.Ct. 270, 4 L.Ed.2d 252 (1960). For this reason, the determination of whether the error in a particular case is a variance or a constructive amendment should not lightly be undertaken. United States v. Flynt, 15 F.3d 1002, 1005 (11th Cir.1994).
. If Floresca was convicted under section 1512(b)(1), then there was a failure to instruct the jury as to an essential element of the crime *718charged. That, however, does not convert a variance into a constructive amendment.
We review here only for plain error. As conclusively demonstrated below in Section III, Floresca was in no way prejudiced by the failure to instruct and, therefore, the failure to instruct is not plain error. See United States v. Childress, 26 F.3d 498, 503-04 (4th Cir.1994); see also United States v. Xavier, 2 F.3d 1281, 1287 (3d Cir.1993).
. The majority seems to view Moore as indistinguishable from the instant case on the basis that, in Moore, the majority concluded that Moore was charged with, and convicted of, “possession of an unlawful firearm,” 512 F.2d at 1256, with the indictment and the proof at trial simply establishing different theories of criminality thereunder; while, in the instant case, the majority asserts that, "[bjecause each describes a different objective of an unlawful tampering, requiring the gov-emment to prove a different specific intent, it is evident that Paragraphs (1) and (3) are separate crimes.” Ante, at 710 n. 9.
Initially, I would note that it is hard to square the majority’s position regarding section 1512(b)(1) and (b)(3) with Moore's unambiguous holding that "possession of a shotgun” and "possession of another firearm” are not distinct crimes. First, the mere fact that Congress has chosen to use a separate statutory section to provide various theories of criminality based upon the definition of a term used in one criminal statute (as is the case with section 5861(d)) as opposed to using subdivisions of the particular criminal statute to provide alternative theories of criminality (as is the case with section 1512(b)) should not affect whether an error is a variance or a constructive amendment. Moreover, I know of no authority, nor does the majority provide any, for the proposition that a specific intent *719element is treated any differently from any other element of a crime in this regard. Indeed, other courts have, in appropriate cases, similarly viewed alternate language in a statutory scheme as defining identical crimes. See., e.g., Jackson v. United States, supra, 359 F.2d at 263 (statute that proscribed robbery “whether against resistance or by sudden or stealthy seizure or snatching” did not, thereby, define distinct crimes, but only identified "way[s] of committing the offense”); United States v. Coulter, 474 F.2d 1004, 1005 (9th Cir.) (not plain error for defendant to be convicted under 18 U.S.C. § 2113(d) of "assault[ ]" during the course of a holdup of a federally insured savings and loan association, even though indictment charged only that, in the course of the holdup, defendant “put[ ] in jeopardy the life of any person by the use of a dangerous weapon or device”; reasoned the court, “the distinction between 'putting a life in jeopardy' and ‘assault’ is not a difference of great magnitude”), cert. denied, 414 U.S. 833, 94 S.Ct. 172, 38 L.Ed.2d 68 (1973).
Even putting the foregoing aside, however, the majority's argument is entirely inapposite. The court in Moore found it important to view the crime with which Moore was charged in the indictment as identical to the crime of which he was convicted because, otherwise, the additional facts introduced as evidence at trial which were not alleged in the indictment would have broadened the bases of conviction. Here, as discussed in the text above, by contrast, the elements of both paragraphs were set out in the indictment and no facts were introduced at trial which were not alleged in the indictment. Thus, the question of whether sections 1512(b)(1) and (b)(3) constitute identical or distinct crimes is wholly irrelevant in this case.
. The majority asserts that "the dissent relies in significant part on Moore and [United States v. Bledsoe, 898 F.2d 430 (4th Cir.), cert. denied, 498 U.S. 986, 111 S.Ct. 521, 112 L.Ed.2d 532 (1990),] to determine that there was no construc-five amendment.” Ante, at 710. This statement is wholly inaccurate. First, as explained in the text, while Moore is inconsistent with the result reached by the majority, whether Moore remains good law in no way affects my treatment and classification of the error in this case. Further, as compared to the error herein and the error in Moore, the error in Bledsoe was distinct and far less egregious. The defendant in Bledsoe was indicted for distributing cocaine “within one thousand feet of the real property comprising a public secondary school.” Id. at 431 n. 1. At trial, the evidence established that Bledsoe had distributed cocaine within 1000 feet of a private, not a public, school. The relevant statutory provision, then found at 21 U.S.C. § 845a(a), proscribed the distribution of a controlled substance within 1000 feet of "a public or private ... secondary school." The majority in Bledsoe found that, because “[a]U secondary schools are either publicly or privately controlled!,] ... the statute is violated by a sale within 1000 feet of any secondary school.” Id. at 432 (emphasis in original). As a consequence, the inclusion of the phrasing “public or private” in the wording of the statute was surplusage and, so, the classification of a school within 1000 feet of which cocaine had been sold was not an essential element of the crime. Thus, even though facts had been introduced at Bledsoe's trial that had not been alleged in the indictment against him, the bases for Bledsoe’s conviction were not broadened thereby. We therefore concluded that Bledsoe had suffered a variance, not a constructive amendment, which we then found to be harmless.
Even the majority recognizes that Bledsoe is "distinguishable on its facts” from Moore and the instant case. Ante, at 711. Despite this concession, and even though this dissent in no part draws support from the court’s holding in Bled-soe, the majority deems it proper so to limit Bledsoe’s value as precedent as effectively to overrule it. See ante, at 711.
. Indeed, at oral argument, even Floresca conceded Olano's applicability.
. Indeed, the fact that, as described infra, the Court explicitly declined to rule out the possibility that, in order for Rule 52(b) to be met, prejudice must be shown in every case, demonstrates conclusively that the Court intended and expected every other part of the Olano analysis to apply and be used in all Rule 52(b) cases.
. The majority asserts that Sullivan is controlling here. See ante, at 712.
. In fact, the real problem here is once again the majority’s mischaracterization of the error in this case as a constructive amendment of the indictment. In a true constructive amendment case, it might well be "utterly meaningless" to query whether a grand jury could or would have indicted the defendant for certain conduct because that conduct would, in fact, have been uncharged.
. Federal Rule of Criminal Procedure 52 provides:
(a) Harmless Error. Any error, defect, irregularity or variance which does not affect substantial rights shall be disregarded.
(b) Plain Error. Plain errors or defects affecting substantial rights may be noticed although they were not brought to the attention of the court.
. Olano & third prong requires, at least in general, a showing of prejudice. I would note that the requirement that an error "affect the substantial rights of the defendant" and one that an error “prejudice the defendant” are not coextensive. Rather, a showing of prejudice requires more than a showing merely that one’s substantial rights have been affected. See United States v. Young, supra, 470 U.S. at 16 n. 14, 105 S.Ct. at 1047 n. 14 ("federal courts have consistently interpreted the plain-error doctrine as requiring an appellate court to find that the claimed error not only seriously affected 'substantial rights,’ but that it had an unfair prejudicial impact on the jury’s deliberations" (emphasis added)). Cf. United States v. Saro, 24 F.3d 283, 287 (D.C.Cir.1994) ("[Ujnless we are to eradicate the need for a timely objection, in plain violation of Rule 52's distinctions, we must be materially more reluctant to find ‘prejudice’ in the absence of a timely objection than when the error was properly raised.”).
Thus, the majority’s assertion that "Stirone ... mean[s] ... that an inquiry into prejudice is not appropriate where a constructive amendment has occurred,” ante, at 712-13, is inaccurate. Stirone does, indeed, “mean what it says,” ante, at 712-13. All Stirone says, however, is that a constructive amendment "destroy[s] the defendant’s substantial right to be tried only on charges presented in an indictment returned by a grand jury.” 361 U.S. at 217, 80 S.Ct. at 273. It says nothing about prejudice to the defendant. Therefore, contrary to the majority’s protestation, "interpreting Olano to require a showing of prejudice in every case” does not, essentially or otherwise, “overrule[ ] Stirone," ante, at 712-13.
. In the wake of Olano, we have held that an error which is susceptible to harmless error analysis must be shown to have prejudiced the result obtained at the defendant's trial in order to rise to plain error. See United States v. Moore, 11 F.3d 475, 481-82 (4th Cir.1993), cert. denied,U.S. -, 114 S.Ct. 1864, 128 L.Ed.2d 486 (1994). However, we have never held that the converse of this statement, i.e., that the prejudice caused by an error which is not susceptible to harmless error analysis is presumed, is a correct statement of law.
. This mitigates strongly against the per se rule, blithely adopted by the majority, that the presence of an error that is not susceptible to harmless error analysis requires reversal as a matter of law.
. The Supreme Court explained in United States v. Young, 470 U.S. at 16 n. 14, 105 S.Ct. at 1047 n. 14:
Following decisions such as United States v. Frady; United States v. Socony-Vacuum Oil Co., supra, and United States v. Atkinson, federal courts have consistently interpreted the plain-error doctrine as requiring an appellate court to find that the claimed error not only seriously affected “substantial rights,” but that it had an unfair prejudicial impact on the jury's deliberations. Only then would the court be able to conclude that the error undermined the fairness of the trial and contributed to a miscarriage of justice.
In other words, “[ojnly” upon a "find[ing] that the claimed error ... had an unfair prejudicial impact on the jury's deliberations ... [is a] court able to conclude that the error undermined the fairness of the trial and contributed to a miscarriage of justice," as required in order for it to be proper for us to exercise our discretionary remedial power.
Thus, the majority's description of "the desire ... to inject a prejudice component into [the final step of the Olano] analysis" as being "bom of reflex and not of contemplation,” ante, at 713-14, is quite inaccurate. Rather, the requirement that prejudice be heavily considered in conducting this portion of the Olano analysis is bom of controlling, explicit Supreme Court precedent. The majority's observation that “ '[a]n error may seriously affect the fairness, integrity or public reputation of judicial proceedings independent of the defendant's innocence,' " ante, at 713 n. 18 (quoting Olano, - U.S. at -, 113 S.Ct. at 1779 (internal quotation marks omitted)), is, though accurate, irrelevant. A prejudice inquiry does not rest on whether the defendant is actually innocent; that an error prejudiced the defendant does not mean that the defendant is actually innocent.
I would also note the absence of support in Olano for the majority’s suggestion that, if, in fact, prejudice under Olano’s third prong need not be shown as to a certain error, then consideration of prejudice under Rule 52(b)’s discretionary analysis is obviated. Any suggestions that prejudice might, in appropriate cases, be omitted from a Rule 52(b) analysis appear only in discussions of Olano's third prong. Cf. United States v. Merlos, 8 F.3d at 51 (rejecting the notion that Sullivan, wherein the Court found that the delivery of a constitutionally deficient reasonable doubt instruction could never be harmless, alters the first and second Olano prongs in determining whether an error under Sullivan warrants reversal under Rule 52(b)).
. In Thetford, two counts of an indictment charged the defendant Thetford with obstruction of justice in violation of 18 U.S.C. § 1510(a), which provided, in pertinent part:
Whoever willfully endeavors by means of bribery, misrepresentation, intimidation, or force, or threat thereof to obstruct, delay, or prevent the communication of information relating to a violation of any criminal statute of the United States by any person to any criminal investigator ... [sjhall be fined not more than $5,000, or imprisoned not more than five years, or both.
The district court instructed the jury that an essential element under section 1510(a) was:
An act by the defendant of willfully (a) endeavoring by means of intimidation and threats of force, to prevent the communication of information relating to a violation of the federal criminal laws, or (b) inflicting bodily injury on any person on account of the giving of any information relating to a violation of the federal criminal laws ....
676 F.2d at 179 (emphasis supplied by the court in Thetford). Though he lodged no objection to the jury instruction given, "Thetford contended] that subsection (b) of the instruction was not contained in the indictment, and that its inclusion in the submission to the jury permitted it to convict him of acts for which he was not charged.” Id. at 180.
The Fifth Circuit rejected Thetford’s reliance on Stirone on two grounds. First, the court of appeals noted that Stirone was not a plain error case. Id. Second, the court observed that, in Stirone, the court’s admission of evidence establishing facts extraneous to the indictment contributed to the broadening of the bases for conviction and thereby to the creation of the constructive amendment. In Thetford’s appeal, by contrast, "significantly, there was no evidence as to [the two counts in question] that could remotely be construed to support" a conviction under *726the challenged portion of the instruction. Id. The court noted that “in the absence of evidence upon which the juty might have convicted on a ground not contained in the indictment, ... the [district] court’s inadvertent” inclusion in its jury instructions of a charge not included in the indictment "is ‘trivial, useless [or] innocuous.’ ” Id. at 180 n. 17 (quoting Stirone, 361 U.S. at 217, 80 S.Ct. at 273 (alteration by the court in Thet-ford)).
. The burden, it is important to note, is not increased insurmountably. Indeed, in true constructive amendment cases, it may be that the burden will be met most of the time.
. Although it does not spell out the argument explicitly, the majority classifies the error of constructive amendment of the indictment as a "structural defect," ante, at 712-14, and then relies upon the First Circuit's opinion in United States v. Colon-Pagan, supra, 1 F.3d 80, for the proposition that the commission below of a “structural defect" will automatically warrant the exercise of Rule 52(b) discretion, ante, at 714 n. 19. ’
Even accepting arguendo the premise that a constructive amendment of the indictment is a “structural defect,” the majority’s argument is flawed. It is true, as noted by the First Circuit in Colon-Pagan, 1 F.3d at 82, that the Court in Arizona v. Fulminante, 499 U.S. 279, 111 S.Ct. 1246, 113 L.Ed.2d 302 (1991), indicated that, “ ‘[w]ithout [certain] basic protections,’ ” the absence of which amount to a structural defect, " 'a criminal trial cannot reliably serve its function as a vehicle for determination of guilt or innocence and no criminal punishment may be regarded as fundamentally fair.'” Id. at 310, 111 S.Ct. at 1265 (quoting Rose v. Clark, 478 U.S. 570, 577-78, 106 S.Ct. 3101, 3106, 92 L.Ed.2d 460 (1986)). This statement, however, taken in the context in which it was made, means only that the complete deprivation of certain "basic protections” can never constitute harmless error. As such, it is inapplicable to the present inquiry. As discussed in the text, the notion that an increase in the burden an accused must demonstrate to warrant recognition that a “basic protection[ ]” has not been accorded as a result of the accused's forfeiture of an objection below does not amount to a deprivation of that “basic protection! ].” The Fulminante quote is meant only to establish that it would be unfair to characterize the deprivation of a "basic protection! ]” as harmless error. To whatever degree such a statement may have bearing on Olano's third prong, we have now passed, it must be borne in mind, to another portion of the Olano analysis, a portion with respect to which the Fulminante quote was not intended to have bearing.
I would further note that the First Circuit in Colon-Pagan did not consider reliance upon the language from Fulminante adequate to support its conclusion of unfairness warranting exercise of Rule 52(b) remedial power. ■ Faced with a constitutionally deficient reasonable-doubt instruction below, after reciting the Fulminante argument outlined above, the First Circuit observed that "common sense” indicated that "[t]he erroneous instruction permitted the jury to convict on the basis of evidence that it may have believed sufficient to justify no more than the most ordinary of decisions — not evidence that proved guilt beyond a 'reasonable doubt.' " I F.3d at 82. Here, of course, the analogous inquiry of whether the grand jury would have indicted Floresca for violation of 18 U.S.C. § 1512(b)(3) does not result in similar unfairness, for, in fact, the indictment herein specifically charged Floresca with intimidating Lopez with the goal of having Lopez lie to the authorities regarding Floresca's illegal activities, conduct prohibited under section 1512(b)(3). See discussion in Section VI.A.l, supra. See also United States v. Gaudin, supra, 28 F.3d at 951-52 (concluding that exercise of Rule 52(b) remedial power was justified not only because of deprivation of what the Ninth Circuit found to be the “structural error” of failing to instruct the jury as to an *727essential element of the crime charged, but also because, had the jury received a complete instruction, it would have been faced with "a serious factual question”).
. Floresca raises a sufficiency of the evidence challenge to his section 1512 conviction which neither I nor the majority, see ante, at 711 n. 11, believes to be of merit.
Floresca also challenges the district court’s decision to increase his offense level pursuant to U.S.S.G. § 2J1.2(b)(l). That guideline provides for an 8-level increase "[i]f the offense involved ... threatening to cause physical injury to a person ... in order to obstruct the administration of justice " Floresca claims that no evidence supports the court's finding that Floresca threatened to harm Lopez's son. Factual findings by the district court with regard to sentencing will not be overturned unless clearly erroneous. United States v. Daughtrey, 874 F.2d 213, 217 (4th Cir.1989). I do not believe that the district court's findings in this regard are clearly erroneous, and would therefore reject this challenge.
