OPINION LUTTIG, Circuit Judge: We sua sponte granted rehearing en banc to consider Rodney Curtis Hamrick’s appeal from convictions resulting from his attempt to assassinate a United States Attorney with a letter bomb. A panel of our court reversed most of Hamrick’s convictions on the grounds that the bomb was neither a “dangerous weapon” under 18 U.S.C. § 111(b) nor a “destructive device” under 18 U.S.C § 924(c)(1) and 26 U.S.C. § 5861(d)-(f). For the reasons that follow, we affirm Hamrick’s convictions and his sentences. I. In 1987, from state prison, appellant mailed letters threatening to murder then-President Ronald Reagan. He was charged with and later pleaded guilty to threatening the life of the President of the United States in violation of 18 U.S.C. § 871(a). For this offense, he was sentenced in July 1988 to five years imprisonment by United States District Judge William M. Kidd. See United States v. Hamrick, No. 88-40 (N.D. W. Va. July 22, 1988) (unreported). While serving this sentence at the Federal Correctional Institute at Petersburg, Virginia, Hamrick built five improvised bombs. The first was determined to have been an inoperable test bomb after it was disarmed by an Army Explosive Ordinance Detail. The next four exploded, one of them seriously injuring a fellow inmate. In connection with these latter incidents, a jury convicted Hamrick of four counts each of the unlawful manufacture of an incendiary device, 26 U.S.C. § 5861(f), possession of an unregistered firearm, id. § 5861(d), and possession of contraband in prison, 18 U.S.C. § 1791(a)(2). He was also convicted for making a bomb threat, 18 U.S.C. § 875(c), in which he threatened to blow up the United States District Courthouse in Washington, D.C., if he were not released. In November 1990, United States District Judge Robert R. Merhige, Jr., sentenced him to ten years imprisonment. See United States v. Hamrick, No. 90-12 (E.D. Va. Nov. 27, 1990) (unreported). During the time that he was in federal prison, Hamrick also committed numerous disciplinary infractions that did not result in criminal charges. The most significant of these were four incidents in which he constructed improvised guns. He fired one of these guns at a fellow inmate and threatened a guard with another. He also was disciplined for making four bomb threats, threatening at various times to blow up the courthouse in Elkins, West Virginia, a United Airlines flight, and the NAACP headquarters in Washington (twice), if he were not released from prison. Hamrick was also caught in possession of a letter containing a “smoke bomb,” which he had addressed to then-President George Bush but had not mailed. In April 1990, while still in federal prison for threatening the life of the President, Hamrick mailed a letter to Judge Kidd on behalf of “the Nazi Socialist Republican Party” in which he threatened to kill the judge and his family. After he was interviewed about the letter by the Federal Bureau of Investigation, Hamrick sent a second letter to Judge Kidd, in which he stated his resent-, ment that the judge had reported his first letter to the FBI, and again threatened Judge Kidd’s life. On the basis of these letters, a jury found Hamrick guilty in March 1991 of threatening to assault and murder a federal judge. See 18 U.S.C.A. § 115(a)(1)(B). Hamrick was sentenced to 51 months imprisonment for this offense, and a year later, we affirmed both his conviction and sentence. United States v. Hamrick, 960 F.2d 147 (4th Cir.1992) (unpublished). Pending prosecution on this charge, from December 18, 1990, until February 14, 1991, Hamrick was incarcerated in the Ohio County Correctional Facility in Wheeling, West Virginia. While there, Hamrick constructed an incendiary bomb from items available to him inside the jail. The bomb comprised a nine-volt battery as a power source, steel wires, three butane cigarette lighters as the explosive, and an unidentified pink substance speculated to be lip balm, which was to serve as the detonator. The plastic case of one of the lighters was filed thin; the pink substance, in which the flints from the lighters had been placed, was positioned over the thin spot; and the wires, leading to the battery and an improvised switch, were run through the pink substance. Hamrick wrapped the bomb in aluminum foil and placed it in a manila envelope between a legal pad and a piece of cardboard. The bomb was designed to detonate when the legal pad was removed from the envelope and the wires of the improvised switch touched. The resulting electrical current was supposed to heat the wire and ignite the detonator, which then would melt the plastic casings of the lighters, free the butane, and ignite it. If fully effective, the bomb could have produced a 1000-degree fireball up to three feet in diameter. This fireball would have burned the skin and eyes of anyone exposed to it. If those exposed were inhaling when the bomb detonated, the fireball could have seared their lungs, possibly resulting in death. Hamrick addressed the envelope containing the bomb to William A. Kolibash, United States Attorney for the Northern District of West Virginia, whose office was responsible for Hamrick’s prosecution, wrote his own return address on the envelope and mailed it. On January 2, 1991, Kolibash received and opened the envelope at his office. The bomb scorched the packaging in which it had been mailed, but did not detonate. Kolibash, realizing that the envelope contained a homemade bomb, fled his office. The United States Marshals, as well as agents from the Federal Bureau of Investigation and the Bureau of Alcohol,- Tobacco, and Firearms were called to the scene. They immediately piled sandbags around the desk and secured the office. An Army bomb disposal expert and his commanding officer were flown to Wheeling from Chambersburg, Pennsylvania. Upon arriving, the expert ordered the evacuation of the entire wing of the building in which the United States Attorney was officed. While wearing a full-body kevlar bomb suit and a kevlar helmet with an inch-thick Plexiglas shield, he X-rayed and examined the bomb. After covering it with a bomb blanket, he finally dismantled it by attaching a hook-and-line set to the bomb and, from thirty feet away and down a flight of stairs, pulling the bomb’s components apart. Immediately after Kolibash had received the bomb, and before it had been dismantled, two FBI agents, after advising Hamrick of his Miranda rights and receiving from him a signed written waiver of those rights, interviewed Hamrick at the Ohio County Jail to determine whether the bomb would explode. Hamrick admitted to the agents that he intended the bomb to detonate within minutes of the envelope being opened. He also stated that he mailed the bomb to Kolibash in retaliation for the pending prosecution. Hamrick then signed a written statement, prepared by one of the agents, in which he admitted constructing and mailing the bomb. He later sent to the United States Marshal a copy of a letter he had written to the West Virginia American Civil Liberties Union in which he again admitted involvement in sending the bomb to Kolibash. Hamrick was charged with the unlawful making of a destructive device, 26 U.S.C. § 5861(f) (Count I); unregistered possession of a destructive device, id. § 5861(d) (Count II); unlawful transfer of a destructive device, id. § 5861(e) (Count III); mailing of a non-mailable article, 18 U.S.C. § 1716 (Count IV); attempted murder of a federal officer, id. § 1114 (Count V); use of a destructive device during and in relation to the attempted murder of a federal officer, id. § 924(c)(1) (Count VI); assault of a federal officer with a dangerous or deadly weapon, id. § 111(b) (Count VII); and use of a destructive device during and in relation to the assault of a federal officer, id. § 924(c)(1) (Count VIII). A jury found Hamrick guilty on all counts and the district court sentenced Hamrick to 210 months imprisonment on the convictions for attempted murder and mailing of a non-mailable article, and to concurrent 120-month sentences for assault with a deadly or dangerous weapon and for the unlawful manufacture, transfer, and possession of a destructive device. The district court also imposed the mandatory sentence of thirty years imprisonment for the section 924(c) violations, to run consecutively to Hamrick’s other sentences. A panel of this court reversed Hamrick’s conviction on count VII on the ground that the dysfunctional bomb was not a deadly or dangerous weapon. It reversed his convictions on counts I — III, VI, and VIII on the grounds that, as constructed, the bomb was dysfunctional and therefore not a destructive device. See United States v. Hamrick, 995 F.2d 1267 (4th Cir.1993) (“Hamrick /”). The United States, at the direction of the Solicitor General, did not petition either for rehearing or for rehearing en banc of the panel’s reversal of Hamrick’s convictions and sentences on these counts. By Order of August 20, 1993, we sua sponte granted rehearing en banc. We now affirm Hamrick’s convictions and sentences in their entirety. II. The panel, apparently on a finding of “plain error,” reversed Hamrick’s conviction for assault of a United States Attorney with a deadly or dangerous weapon under 18 U.S.C. § 111(b), reasoning that, because the bomb could not explode, it could not, as a matter of law, be a deadly or dangerous weapon. Hamrick I, 995 F.2d at 1272. We reject this reasoning and affirm en banc Hamrick’s assault conviction. Hamrick did not advance before the panel the argument that the bomb he sent to Koli-bash was not a “dangerous” or “deadly” weapon within the meaning of section 111(b). Nor does he advance this argument before the court sitting en banc. Indeed, Hamrick’s counsel candidly conceded at argument before the full court that the bomb was a dangerous weapon under existing Supreme Court precedent, and in particular under McLaughlin v. United States, 476 U.S. 16, 106 S.Ct. 1677, 90 L.Ed.2d 15 (1986). We believe that counsel was correct to concede this point. In McLaughlin, a unanimous Supreme Court held, in an opinion that was barely two pages long, that an un loaded handgun used to commit an assault during a bank robbery is a “dangerous weapon” under 18 U.S.C. § 2113(d), the federal bank robbery statute. The Court concluded that “[t]hree reasons, each independently sufficient ” supported its conclusion: First, a gun is an article that is typically and characteristically dangerous; the use for which it is manufactured and sold is a dangerous one, and the law may reasonably presume that such an article is always dangerous even though it may not be armed at a particular time or place. In addition, the display of a gun instills fear in the average citizen; as a consequence, it creates an immediate danger that a violent response will ensue. Finally, a gun can cause harm when used as a bludgeon. McLaughlin, 476 U.S. at 17-18, 106 S.Ct. at 1678 (footnote omitted) (emphasis added). This reasoning applies with the same force to 18 U.S.C. § 111(b), the assault of a federal officer statute under which Hamrick was convicted. See United States v. Gometz, 879 F.2d 256, 258-59 (7th Cir.1989) (“Although the McLaughlin case interpreted 18 U.S.C. § 2113, we think that its logic applies to § 111, given that the two provisions contain identical language and are cross-referenced.”), cert. denied, 493 U.S. 1033, 110 S.Ct. 752, 107 L.Ed.2d 768 (1990). McLaughlin dictates what common sense would confirm, namely, that the bomb sent to Kolibash by Hamrick was a “dangerous weapon” within the meaning of section 111(b). Two of the Court’s rationales in McLaughlin — the first and the second — are specifically applicable to the case before us. As to the first of these rationales, the question obviously is not whether a dysfunctional bomb is typically and characteristically dangerous, or even whether the combination of parts constituting the bomb sent by Hamrick (assuming they exist elsewhere) is typically and characteristically dangerous, no more so than the question in McLaughlin was whether an unloaded handgun is typically dangerous. Rather, the question is whether a bomb is typically and characteristically dangerous. Of course it is, and the use for which it is produced is a dangerous one. Thus, the law may presume, as it may with respect to a handgun, that a bomb is always dangerous even though, due to the fortuity of malfunction, faulty construction, or defective design, it may in a particular ease be incapable of inflicting injury. See Gometz, 879 F.2d at 259 (zip gun was dangerous weapon, although because of design defect it could not expel metal fragments as intended). Of course, the presumption that the bomb sent by Hamrick was dangerous was fully warranted, even though the bomb appears to have been dysfunctional. See infra at 882-883, n. 8-9 (citing cases); cf. United States v. Rushcamp, 526 F.2d 1380, 1382 (6th Cir.1975) (rocket launcher with dysfunctional firing mechanism a destructive device); United States v. Tankersley, 492 F.2d 962, 966 (7th Cir.1974) (paint-remover filled bottle with dud firecracker detonator was destructive device); United States v. Greer, 404 F.Supp. 1289, 1293 (W.D. Mich.1975) (collection of blasting materials a destructive device even though no power source), aff'd, 588 F.2d 1151 (6th Cir.1978). At trial, the government’s two experts testified that the inflammable butane contained in the lighters, if released and ignited, could have produced a large 1000-degree fireball capable of killing persons exposed to its heat. One of these experts, Warren Parker, testified that a nine-volt battery by itself could have easily generated enough heat to have melted the plastic easing of the lighters, liberating the butane within and creating an explosive cloud which could have been detonated by even the smallest spark. And they both testified that the substitution of other substances readily available to Hamrick inside the Ohio County Jail (such as hamburger grease or matehheads) for the pink substance actually used in the bomb or some other slight modifications in the bomb’s design (such as adding additional batteries or using thinner wire) would have rendered it fully operable. As to the second of the McLaughlin rationales, the display of a bomb, like the display of a gun, instills fear in the average citizen, whether or not it is actually capable of inflicting injury. That this is so is amply borne out by the reaction to the bomb received by United States Attorney Kolibash. The United States Attorney fled his office in fear and summoned the United States Marshals, the FBI, and the ATF. The United States Attorney’s office was sandbagged and an Army bomb disposal expert was flown in from another state. The bomb disposal expert thought the risk of serious injury sufficiently serious to wear a bomb suit to examine the device and, even after examining it, to dismantle it by remote means. “Congress regarded incitement of fear as sufficient to characterize an apparently dangerous article (such as a wooden gun) as ‘dangerous’ within the meaning of [§ 2113(d) ].” McLaughlin, 476 U.S. at 18 n. 3, 106 S.Ct. at 1678 n. 3 (citing 78 Cong. Rec. 8132 (1934)). So too for the same reason is a bomb which, unbeknownst to its recipients is inoperable, “dangerous” within the meaning of section 111(b). Every circuit court to address this or a similar issue has held accordingly. See Gometz, 879 F.2d at 259 (dysfunctional zip gun instills fear and is therefore dangerous); United States v. York, 830 F.2d 885, 891 (8th Cir.1987) (broken pellet gun a dangerous weapon under § 2113(d)), cert. denied, 484 U.S. 1074, 108 S.Ct. 1047, 98 L.Ed.2d 1010 (1988). Indeed, every circuit court considering even the question of whether a fake weapon that was never intended to be operable has come to the same conclusion. See United States v. Spedalieri, 910 F.2d 707, 709 (10th Cir.1990) (“fake bomb, as a matter of law, may constitute a dangerous weapon [under section 2113(d) ], regardless of its actual capabilities, when a victim confronted with it is placed in reasonable expectation of danger”); United States v. Marx, 485 F.2d 1179, 1185 (10th Cir.1973) (fake bomb, because it placed victim in reasonable expectation of death or serious injury, was a dangerous weapon under section 2113(d)), cert. denied, 416 U.S. 986, 94 S.Ct. 2391, 40 L.Ed.2d 764 (1974); cf. United States v. Boyd, 924 F.2d 945, 947-48 (9th Cir.) (road flare, which appeared to be dynamite, a dangerous weapon under Guidelines), cert. denied, 502 U.S. 828, 112 S.Ct. 98, 116 L.Ed.2d 70 (1991). The same conclusion has been reached even in circumstances where there was no weapon at all — fake or otherwise— but only apparently a weapon. See United States v. Benson, 918 F.2d 1, 3 (1st Cir.1990) (feigned gun, actually a pocket knife, held in robber’s pocket, a dangerous weapon under § 2113(d)); cf. United States v. Dixon, 982 F.2d 116, 122-23 (3d Cir.1992) (hand underneath a towel, represented to be a gun, a dangerous weapon under Guidelines), cert. denied, — U.S. -, 113 S.Ct. 2371, 124 L.Ed.2d 276 (1993); United States v. Taylor, 960 F.2d 115, 116 (9th Cir.1992) (bulge in waistband, represented to be a gun, a dangerous weapon under Guidelines); but cf. United States v. Hawkins, 901 F.2d 863, 865 (10th Cir.1990) (upward departure for false claim of being armed inappropriate); United States v. Coe, 891 F.2d 405, 411 (2d Cir.1989) (same). An assault with a dysfunctional bomb poses the same or similar dangers and gives rise to the same kind of harms as an assault with an unloaded gun. Even a dysfunctional bomb engenders in the assault victims the fear of bodily injury beyond that instilled by a simple assault, see United States v. Martinez-Jimenez, 864 F.2d 664, 666 (9th Cir.), cert. denied, 489 U.S. 1099, 109 S.Ct. 1576, 103 L.Ed.2d 942 (1989); United States v. Mahler, 891 F.2d 75, 77 (4th Cir.1989) (quoting Martinez-Jimenez and applying it to sentencing guidelines); see also United States v. Beasley, 438 F.2d 1279, 1282-83 (6th Cir.), cert. denied, 404 U.S. 866, 92 S.Ct. 124, 30 L.Ed.2d 110 (1971), fear that can, for instance, bring on heart attacks and other adverse medical consequences. See United States v. Medved, 905 F.2d 935, 940 (6th Cir.1990), cert. denied, 498 U.S. 1101, 111 S.Ct. 997, 112 L.Ed.2d 1080 (1991). Law enforcement authorities must respond to the perceived threat of explosion, driving them to more deliberate and less efficient means of responding to the assault. Martinez-Jimenez, 864 F.2d at 666. And even though it is actually incapable of inflicting the injuries it threatens, an inoperable bomb creates a danger that a violent response will ensue. See McLaughlin, 476 U.S. at 17, 106 S.Ct. at 1678. Ordinarily, this danger will arise because those threatened, their rescuers, or the police, can be expected to respond with force and possibly deadly force, and thereby endanger the safety of victims, bystanders, and even the perpetrator. See, e.g., Martinez-Jimenez, 864 F.2d at 666; Beasley, 438 F.2d at 1283. But even where, as here, the weapon has been mailed and there is little risk of retaliation against the sender which would endanger those involved, there is still an immediate danger of injury to those who flee or otherwise furiously react to the perceived threat to their lives, and to innocent bystanders. In short, the sender of an inoperable mail-bomb, although distant from his victims, sets in motion events that pose danger to human life and harm society no less so than the criminal courier who delivers the bomb to his victim by hand. We thus conclude as a matter of law that Hamrick’s bomb could be considered by the jury to constitute a “dangerous weapon” under 18 U.S.C. § 111(b). Accordingly, we affirm his Count VII conviction for assault of a federal officer with a dangerous or deadly weapon. III. The jury also convicted Hamrick for the unlawful making of a destructive device, 26 U.S.C. § 5861(f) (Count I); the unregistered possession of a destructive device, id. § 5861(d) (Count II); the unlawful transfer of a destructive device, id. § 5861(e) (Count III); the use of a destructive device during and in relation to the attempted murder of a federal officer, id. § 924(c)(1) (Count VI); and the use of a destructive device during and in relation to the assault of a federal officer, id. § 924(c)(1) (Count VIII). The panel reversed these five convictions, holding that the jury instructions were “plain error.” See Hamrick I, 995 F.2d at 1271-72. Relying ultimately on United States v. Malone, 546 F.2d 1182, 1184 (5th Cir.1977) (“the complete absence of explosive material would prevent the component parts ft’om being a destructive device”), the panel held that Hamrick’s bomb was not a destructive device because not all of the necessary component parts of a bomb were actually in Hamrick’s possession and working. These convictions are now affirmed by an equally divided court. IV. Hamrick also was convicted of sending through the mails a nonmailable article, a mechanical and chemical device which might have ignited, with the intent to injure or kill another. See 18 U.S.C. § 1716. Hamrick challenges the sufficiency of the evidence supporting this conviction, arguing that since his bomb was dysfunctional, it was not a nonmailable article. A finding that Hamrick’s bomb was capable of operating as designed is, contrary to Hamrick’s assertions, unnecessary to support a conviction under section 1716. Nonmaila-ble matter is statutorily defined as: explosives, inflammable materials, infernal machines, and mechanical, chemical, or other devices or compositions which may ignite or explode, ... and all other natural or artificial articles, compositions, or material which may kill or injure another, or injure the mails or other property.... Id. § 1716(a). Although Hamrick’s bomb, as constructed, may have been incapable of functioning as a bomb, it was comprised of cigarette lighters containing inflammable liquified butane. As noted, expert witnesses testified that if one of the lighters were ruptured, the butane within could easily have ignited, creating a fireball. Indeed, the plastic casing of one of the lighters had been scraped thin, further increasing the risk it might rupture and ignite during handling by the Postal Service. Cf. United States v. Merrill, 746 F.2d 458, 461 (9th Cir.1984) (.22 caliber bullets, which could have been detonated by mechanical canceling machines, were nonmailable), cert. denied, 469 U.S. 1165, 105 S.Ct. 926, 83 L.Ed.2d 938 (1985). Viewing this evidence in the light most favorable to the government, see, e.g., Jackson v. Virginia, 443 U.S. 307, 319, 99 S.Ct. 2781, 2789, 61 L.Ed.2d 560 (1979); United States v. Tresvant, 677 F.2d 1018, 1021 (4th Cir.1982), we conclude that a reasonable jury could easily have found that Hamrick mailed a device which might have ignited, and was therefore guilty of violating section 1716. V. Hamrick also argues that the evidence was insufficient to support a finding that he possessed the intent required for conviction either for assault, see 18 U.S.C. § 111(b), or for attempted murder, see id. § 1114, of United States Attorney Kolibash. He argues that he had intended only to register his displeasure at being prosecuted by sending Kolibash a joke bomb, one which he never intended to detonate. We disagree. From the evidence adduced at trial, a reasonable jury could easily have found that Hamrick mailed the bomb he had built with the intent that it would explode and kill United States Attorney Kolibash. The government’s experts testified that the bomb had been designed to explode when the envelope in which it was mailed was opened and that it was too complete to have been meant as a hoax. Moreover, in his statements to the FBI and his signed confession, Hamrick himself admitted that he had intended the bomb to explode and had mailed it to Kolibash in retaliation for being brought to Wheeling to stand trial. In his letter to the West Virginia American Civil Liberties Union, Hamrick again implicated himself in the attempted bombing. Finally, the very circumstance of Hamrick sending a bomb to the United States Attorney responsible for his prosecution supports an inference of intent. This evidence is more than sufficient to support the conclusion that Hamrick intended the bomb to explode and kill a United States Attorney. The jury did not regard the bomb as a joke (nor do we) and was not required to so consider it. VI. Hamrick also claims that the district court erred by refusing to instruct the jury on the theory of legal impossibility as a defense to the charge of attempted murder. The defense of legal impossibility is available where the defendant’s acts, even if fully carried out as intended, would not constitute a crime. Hamrick contends that, because his bomb was incapable of exploding, he could not have committed or attempted murder. Had Hamrick’s acts been carried out as he intended, i.e., if the bomb had exploded when Kolibash opened the envelope, the substantive crime of attempted murder (if not murder itself) would have been committed. The defense of legal impossibility therefore was simply not available to Hamrick. Though not denominated as such, Hamrick appears to have been actually seeking an instruction on factual impossibility. Factual impossibility exists “where the objective is proscribed by the criminal law but a ■factual circumstance unknown to the actor prevents him from bringing it about.” United States v. Conway, 507 F.2d 1047, 1050 (5th Cir.1975). However, factual impossibility is traditionally not a defense to a charge of attempt, and we now join those circuits that have expressly held that it is not a defense to an attempt crime. United States v. Medina-Garcia, 918 F.2d 4, 8 (1st Cir.1990); United States v. Contreras, 950 F.2d 232, 237 (5th Cir.1991), cert. denied, — U.S. -, 112 S.Ct. 2276, 119 L.Ed.2d 202 (1992); United States v. Peete, 919 F.2d 1168, 1175-76 (6th Cir.1990); United States v. Luttrell, 889 F.2d 806, 810 (9th Cir.1989), vacated in part on other grounds, 923 F.2d 764 (9th Cir.1991), cert. denied, — U.S. -, 112 S.Ct. 1558, 118 L.Ed.2d 207 (1992). The district court did not err by refusing to charge the jury on either legal or factual impossibility. See United States v. Camejo, 929 F.2d 610, 614 (11th Cir.1991), cert. denied, 502 U.S. 880, 112 S.Ct. 228, 116 L.Ed.2d 185 (1991). VIL Hamrick also challenges three evidentiary rulings made by the district court. He contends that the court erred by allowing the government to cross-examine his expert about admitted errors in the expert’s testimony in previous cases, that his letter to the West Virginia American Civil Liberties Union — in which he admitted involvement in sending a “letter bomb” to Kolibash — was irrelevant and therefore improperly admitted, and, without explanation, that his confession was involuntary. We find these contentions to be wholly without merit. Both the allowance of cross-examination and the admission of Hamrick’s letter to the ACLU chapter were well within the sound discretion of the trial court. And there is no basis whatsoever for questioning the voluntariness of Hamrick’s confession. VIII. The district court sentenced Hamrick to thirty years imprisonment for the use of a destructive device during and in relation to a crime of violence, this sentence to run consecutively to all other sentences. This sen-' tenee was imposed pursuant to 18 U.S.C.A. § 924(c)(1), which provides in pertinent part: Whoever, during and in relation to any crime of violence ... uses or carries a firearm, shall, in addition to the punishment provided for such crime ..., be sentenced to imprisonment for five years, ... and if the firearm is ... a destructive device ... to imprisonment for thirty years. Id. (emphasis added). Hamrick contends that the terms “firearm” and “destructive device” are interchangeable and that the district court thus should have imposed the shorter sentence prescribed for the use of a “firearm.” While “firearm” is defined to include, inter alia, “destructive device,” see 18 U.S.C. § 921(a)(3), the terms are not strictly interchangeable; rather, a “destructive device” is a subset of “firearm,” the use of which Congress has chosen to punish more severely. The statute is unambiguous that the use of a destructive device during and in relation to a crime of violence shall be punished by thirty years imprisonment. The terms of imprisonment specified by section 924(c)(1), therefore, are mandatory, and the district court is without discretion to deviate from the plain command of the statute. See, e.g., United States v. Dumas, 934 F.2d 1387, 1389-90 (6th Cir.), cert. denied, 502 U.S. 1006, 112 S.Ct. 641, 116 L.Ed.2d 658 (1991); United States v. Hatch, 925 F.2d 362, 363 (10th Cir.1991); United States v. Grinnell, 915 F.2d 667, 668-69 (11th Cir.1990). It has been suggested that a thirty year additional sentence for the use of an improvised dysfunctional incendiary bomb in the attempted assassination of a United States Attorney is too harsh. We do not share this view. However, even if we were of this view, we would have no choice but to enforce this sentence. We have no authority under the law to do otherwise. The judgment of the district court is, in all respects, affirmed. AFFIRMED. . The presentence report in the present case detailed Hamrick's misconduct while in prison. The district court adopted the factual findings of this report and, after imposing sentence, ordered the report placed under seal. There being no apparent risk that the information contained in this report would impair Hamrick's rehabilitation, and indeed there being risk to others from the unavailability of the information recited in the report, we hereby order the seal lifted to the extent it covers the information discussed herein. . Hamrick's criminal activities at the Ohio County Jail did not end with his attempt to murder the United States Attorney. On February 12, 1991, Hamrick, brandishing what appeared to be a small caliber pistol, attempted to escape. His attempt ended only when a deputy sheriff ordered him, at gunpoint, to drop the pistol. The pistol was a fake, constructed from toilet paper and duct tape. Hamrick later pleaded guilty to attempted escape, 18 U.S.C. § 751(a), and was sentenced to five years imprisonment, the sentence to run concurrently with those imposed for the attempted bombing. United States v. Hamrick, No. 91-55 (N.D. W. Va. Jan. 28, 1992) (unreported). See also infra note 3. . The assault of a federal officer statute, 18 U.S.C. § 111, provides in relevant part: (a) In general. — Whoever— (1) forcibly assaults, resists, opposes, intimidates, or interferes with any person designated in [18 U.S.C. § 1114] while engaged in or on account of the performance of official duties; shall be fined under this title or imprisoned not more than three years, or both. (b) Enhanced Penalty. — Whoever, in the commission of any acts described in subsection (a), uses a deadly or dangerous weapon, shall be fined under this title or imprisoned not more than ten years, or both. . 18 U.S.C. § 2113(d) provides: Whoever, in committing, or in attempting to commit, any offense defined in subsections (a) and (b) of this section, assaults any person, or puts in jeopardy of life any person by use of a dangerous weapon or device, shall be fined not more than $10,000 or imprisoned not more than twenty-five years, or both. . There is no question that Hamrick was convicted under the "dangerous weapon” prong of section 111(b). Other than the district court's judgment form, which uses the abbreviated description of the count, "Assault on U.S. Attorney with a deadly weapon," J.A. at 442, there is no support whatsoever for a contrary conclusion. The jury instructions tracked section 111(b) precisely, using the phrase “deadly or dangerous weapon,” id. at 375; the indictment, J.A. at 11, and the jury verdict form, id. at 387, both read “deadly and dangerous weapon.” The presentence investigation report describes the count as "Assault with a Dangerous Weapon,” id. at 448. The jury was not instructed on the meaning of either “dangerous” or "deadly.” . Parker testified that the plastic casing of the lighters would start to soften at 300 degrees Fahrenheit, and would run like melted candle wax at approximately 350 degrees. J.A. at 206, 209, 218. He stated that that "temperature could easily be attained by a dead short across a 9-volt battery with the type of steel wire involved here.” Id. at 206. And the defense expert, Patrick Kennedy, testified that in his reconstructed bombs, the wire reached 428 degrees Fahrenheit, id. at 291, 294, and in one case melted polyethylene, id. at 293. Parker further testified that because the butane inside the lighters was under pressure, "merely weakening the walls [of the lighters] enough to allow that [butane] to vent would act as a mechanism for the function of this bomb." Id. at 207. He continued that once released from the lighters, the butane would "affect somewhere from 10 to 50 times the volume of air around it creating an explosive atmosphere. So that all you need then is a small spark_" Id. at 208. . See also United States v. Benson, 918 F.2d 1 (1st Cir.1990): The debate surrounding the adoption of what is now section 2113 evinces congressional concern for the dangerousness of the effects of the robber's use of a device, not merely the inherent dangerousness of the device. See 78 Cong. Rec. 8132 (1934) (provision would cover use of a bottle of water which robber claimed to be nitroglycerin); see also Martinez-Jimenez, 864 F.2d 664, 667 (9th Cir.1989). Id. at 3 n. 5; id. at 3 ("The dangerousness of an instrumentality ... is not necessarily determined simply by its inherent capacity to inflict harm, but by the dangerousness of the response it may reasonably be expected to provoke on the part of persons who perceive that the instrumentality is dangerous.")

(same), cert. denied, 489 U.S. 1099, 109 S.Ct. 1576, 103 L.Ed.2d 942 (1989). The only circumstance in which section 2113(d) has been held inapplicable to the use of a toy gun was where the gun was concealed during a bank robbery and never displayed, i.e., where it was never "used." See United States v. Perry, 991 F.2d 304, 309-10 (6th Cir.1993). . The Internal Revenue Code defines the term "destructive device” to include "any explosive, incendiary, or poison gas ... bomb" and numerous similar devices. 26 U.S.C. § 5845(f)(1). The definition also includes "any combination of parts either designed or intended for use in converting any device into a destructive device [such as an explosive, incendiary, or poison gas bomb] and from which a destructive device may be readily assembled.” Id. at § 5845(f)(3). An identical definition of "destructive device" appears at 18 U.S.C. § 921(a)(4) and is applicable to section 924(c)(1). . Congress specifically added destructive devices to the class of firearms whose use is punished by the thirty year sentence in the Crime Control Act of 1990, Pub L. No. 101-647, § 1101, 1990 U.S.C.C.A.N. (104 Stat.) 4789, 4829. This Act became effective upon enactment on November 29, 1990.
LUTTIG, Circuit Judge, concurring: The public is entitled to know all of the relevant facts underlying this or any other prosecution and, as an inferior court, we have a solemn obligation to the Supreme Court of the United States to include all such facts in the opinions of this court. From time to time, of course, there will be a disagreement within the court over the relevance of certain facts and testimony to the issues addressed by the court, quite apart from any disagreement over the legal reasoning underlying the court’s ultimate decision to affirm or reverse the defendant’s convictions. WTien there is such a disagreement over the relevance of particular facts, we have an affirmative obligation to explain the basis for our respective conclusions as to their relevance, in order that the public and the Supreme Court be fully informed. The extent to which we insist upon a complete recitation of all potentially relevant facts has profound implications for further review by our Nation’s highest tribunal, for the lives of those whom our decisions touch, and for the public’s perception of the integrity of the court as an institution of government. I. In this case, Chief Judge Ervin and Judge Hamilton maintain that the government witness’ testimony that Hamrick’s bomb .was capable of detonating as constructed without any additional parts, is irrelevant to whether Hamrick’s bomb was a dangerous weapon, and that the court should include no reference to this testimony. See post at 890 n. 2 (Hamilton, J., concurring); post at 891-893 n. 1 (Ervin, Chief Judge, dissenting). Both of my colleagues refuse even to join Part III of the court’s opinion, which states in four innocuous sentences that Hamrick’s “destructive device” convictions are affirmed by an equally divided court, because two of these four sentences, in reciting the panel’s holding and reasoning on the “destructive device” convictions, allude to the testimony to which they object. This testimony was not cited or discussed in the original panel’s unanimous opinion reversing Hamrick’s convictions, see 995 F.2d 1267 (4th Cir.1993); indeed, the testimony was incorrectly characterized in the single passage in the panel opinion that obliquely references it, see discussion infra. It is likewise not mentioned by Chief Judge Ervin in his dissent in this case. Thus, were we not to address this testimony, it would never be publicly known. This testimony is not only highly relevant to the issues addressed by the court, but is the single most relevant evidence in the case. It is not only directly relevant to Hamrick’s Count VII conviction for assault of a federal officer with a dangerous weapon; it also confirms that Hamrick’s convictions on Counts I, II, III, VI, and VIII are unassailable under any plausible interpretation of the term “destructive device,” including that adopted by the original panel. I do not believe that any member of the court is foreclosed from discussing this testimony merely because other members of the court may disagree that it is relevant. I further believe, for the reasons set forth below, that we would disserve the public and the Supreme Court were we not to address this particular testimony. A. The testimony, which is briefly discussed in the court’s opinion, see ante at 881-882, is primarily that of Mr. Warren Parker, one of the government’s chief witnesses. The whole of the panel’s reference to Parker’s testimony appears in the following two sentences: The final expert witness’s testimony was not certain on whether the bomb as constructed could have detonated. He testified, however, that with the substitution of readily available materials, the bomb could have exploded. 995 F.2d at 1270. In fact, Parker testified unequivocally that the bomb as constructed could have detonated, and that it may well have failed to detonate only because its parts had been disturbed during mailing. Specifically, Parker testified that the wires, which ran from the batteries to the butane lighters, themselves could have become so hot as to detonate the bomb, without the addition of a single other part: [M]erely ... weakening the walls [of the lighters] enough to allow that [butane] to vent would act as a mechanism for the function of this bomb. In this case, it is— it is possible that that wire could heat enough to do that, a spark or flame be generated by the heated wire sufficient to ignite the thing, producing the fire ball ... at least several feet in diameter ... [and] well over a thousand degrees. J.A. at 207-08 (emphasis added). Even Hamrick’s counsel understood Parker to have so testified. See id. at 215 (statement by John Pizzuti) (“You testified ... that it was possible that the wire in this alleged bomb could heat enough to cause ignition to produce a fire ball.”). In addition to his testimony that the bomb could have been detonated by the heat from the wires alone, Parker also testified that had the yellow sheets of legal paper in the letter bomb become inflamed, as intended, rather than simply been scorched, they, too, could have detonated the bomb: Q: [Mr. Parker,] [h]ave you formed an opinion concerning the effect on the functioning of the device if the yellow legal pad papers had ignited? A: Well, if any open flame would have been a source of ignition for the butane contained in the lighters. Q: Would that include the yellow legal pad? A: Including the yellow legal pad. Id. at 212. Parker went on to explain that, in his view, it may well have been that the bomb failed to detonate only because its parts were jostled in the mail. United States Attorney Horne asked Parker whether he had “formed an opinion as to the effect of mailing of the device on whether or not it would function.” Id. at 210. After observing that in his experience a “large portion” of letter bombs fail to detonate because parts become dislocated in the mails, Parker testified: I believe that shipping [this particular device] through the mail and the handling it received could well have affected its functional ability and caused it to be dysfunctional. Id. Parker thereafter testified as to the “commonly available” materials that could have been substituted for the pink substance as fuses. The panel, characterizing this testimony, said that although Parker “was not certain on whether the bomb as constructed could have detonated,” he testified that it could have exploded “with the substitution of readily available materials.” 995 F.2d at 1270. However, Parker actually testified not that “the bomb could have exploded” only with the substitution of these materials, but rather that the substitution of these materials would have enhanced the likelihood that the bomb would detonate: Q: [Mr. Parker,] [h]ave you formed an opinion as to whether modifications using commonly-available materials could have been made to increase the likelihood that the device would junction? A: I would be reluctant to be a bomb instructor, but certainly many common materials that I would have available or that are available could have improved the possibility of that to dysfunction [sic] considerably. Q: Have you formed an opinion whether commonly available materials might have been substituted for the pink substance to enhance the chances for it to function? A: Well, the laboratory analysis established that the pink substance was not flammable. Had a flammable material been there, that would have greatly enhanced its probability of functioning. Q: Have you formed an opinion whether or not hamburger grease could have served that function? A: Hamburger grease would be one thing that would burn. Q: Have you formed an opinion whether or not WD — 10 could have served that function? A: Certainly it has a flammability characteristic. Q: Have you formed an opinion whether or not match heads could have served that function? A: Very easily match heads could cause that to happen. Q: Have you formed an opinion whether or not toilet paper could have served that function? A: Yes, any readily available ignitable material substituted for the apparently nonflammable material would have enhanced its ability to have worked. Id. at 210-12 (emphases added). In sum, Parker’s testimony, which was not cited, quoted or discussed by the panel, and which is not cited, quoted or discussed by the dissent or Judge Hamilton, exposes the error of the panel when it stated that Parker “was not certain on whether the bomb as constructed could have detonated,” and when it said that Parker testified that the device could only have exploded with the substitution of other materials. And it confirms the panel’s error when it concluded that, [i]n the instant case, unlike [United States v.] Morningstar [456 F.2d 278 (4th Cir.1972)], Hamrick was not in possession of all of the parts needed to construct a destructive device within the meaning of the statute. Hamrick did not have all of the necessary parts in order for the dysfunctional bomb to qualify as a destructive device. As in Malone, a key component of the device was missing. The unidentified pink substance, serving as the ignitor, was dysfunctional. Moreover, an expert witness testified that the nine-volt battery could not have produced sufficient heat to ignite any number of readily available substitute fuses.... [T]he device is incapable of detonation. The bomb was incapable of detonating; therefore it cannot be a destructive device under section 5845(f) or its counterparts. 995 F.2d at 1271. More importantly, Parker’s testimony exposes the error that would be worked were the court today to reverse either Hamrick’s Count VII conviction, as urged by the dissent, or his convictions under Counts I, II, III, VI, and VIII, as urged by the dissent and Judge Hamilton. B. Chief Judge Ervin and Judge Hamilton argue that no reference to Parker’s testimony should be made, even by the majority of the court that affirms Hamrick’s conviction for use of a “deadly or dangerous weapon,” on the ground that whether Hamrick’s device would explode is irrelevant to the question of the bomb’s dangerousness. See, e.g., post at 890-93 n. 1 (Ervin, Chief Judge, dissenting); post at 890 n. 2 (Hamilton, J., concurring) (referring to court’s “unnecessary and unfortunate reliance on” government expert’s testimony). Such an argument requires no response. It is self-evident that the fact that a bomb could explode is relevant to its dangerousness. One need look no further than to the fact that Parker’s testimony — that the device was fully capable of detonation — completely undermines Chief Judge Ervin’s own rationale for concluding that the bomb was not a dangerous weapon, namely, that the device “lacked at least one necessary element to make it work,” and therefore was incapable of inflicting injury or death, see post at 894. Parker’s testimony speaks directly, as well, to the McLaughlin criteria, under which the dangerousness vel non of Hamrick’s device is assessed. It establishes that the first of these criteria — that the article be typically and characteristically dangerous and be manufactured for a dangerous use — is indisputably proven. For no one could maintain that a bomb capable of detonation is not typically dangerous and manufactured for a dangerous use. As Judge Hamilton observes, these are matters of “[p]ure common sense.” See post at 890 n. 2 (Hamilton, J., concurring). Moreover, by proving beyond any question that the device was in fact capable of injuring or killing persons and destroying property, this testimony also eliminates the issue of putative dangerousness that gives rise to Judge Hamilton’s conclusion that he is “constrained” by Supreme Court precedent to affirm Hamrick’s Count VII conviction, see post at 890-91. Apart from its obvious relevance to the dangerousness of Hamrick’s bomb, Parker’s testimony also provides more than enough basis for a reasonable juror to conclude, under any reasonable interpretation of the term “destructive device” — including the panel’s notion that all parts necessary for the device to detonate must be in the possession of the defendant — that Hamrick’s Counts I, II, III, VI, and VIII convictions should have been affirmed by the panel and must be affirmed here. Given the testimony elicited by the government from Parker, among others, it is plain that all of Hamrick’s convictions must be affirmed under any reasonable interpretation of the terms “dangerous weapon” and “destructive device.” In this particular ease, this is little more than simple recognition by the law that Hamrick is a proven criminal with a demonstrated willingness to construct and mail bombs to any public official of whose actions he disapproves. That he is such is evident from his convictions and activities prior to those underlying this appeal, which the panel also nowhere mentioned and the dissent likewise contends are irrelevant. It is evident even from his activities since the time of his appeal, including the fact that it appears that only nine days after this case was argued before the court en banc, Ham-rick sent yet another bomb from Marion Federal Penitentiary to Special Assistant United States Attorney David J. Horne, who had represented the United States at Ham-rick’s trial in the district court and before the original and en banc panels of this court. II. Chief Judge Ervin does not share my understanding of our responsibility to the public and to the Supreme Court in a ease such as this. In his view, unless there is a majority of judges who join a single opinion for the court, we have no duty to the public, the parties or even to the Supreme Court, to address all of the facts that may bear on the resolution of the defendant’s legal claims. Thus, he believes that where, as here, a majority of the court agrees to dispose of the defendant’s claim in the same way, but only a plurality opinion emerges, there should be no discussion of those facts whose relevance the plurality and the dissent disagree over. Such discussion, in his judgment, amounts to nothing more than “provid[ing] fodder to the [Supreme] Court.” With respect, I simply cannot subscribe to this view. In my opinion, we have no higher obligation in any context than to set forth fully and faithfully the facts to which the law is to be applied. The parties are no less bound by a plurality opinion. With a plurality opinion, no less than with a majority opinion, the Supreme Court must decide on the facts presented whether the defendant has been constitution-ahy denied his life or liberty. Chief Judge Ervin, because he fails to acknowledge the difference between the reasoning of a decision and the underlying facts of a case, suggests that the Supreme Court agrees with his view of our responsibility. It does not. Even putting to one side the obvious difference between a Court of Appeals and the Supreme Court in terms of the unre-viewability of decisions, the Supreme Court always discusses both the relevant facts and the holding by the court from which the appeal is taken, where, as here, it disposes of a case by a plurality vote. It even discusses the facts and holding below when it affirms one of several issues by an equally divided court, as we do in this case. See, e.g., United States v. Zolin, 491 U.S. 554, 109 S.Ct. 2619, 105 L.Ed.2d 469 (1989); Carpenter v. United States, 484 U.S. 19, 108 S.Ct. 316, 98 L.Ed.2d 275 (1987). Indeed, it is odd that Chief Judge Ervin cites Carpenter as an example of a case in which the Court provided none of the underlying facts or the holding below; the Court recited both. Carpenter, 484 U.S. at 22-24, 108 S.Ct. at 318-20. The only context in which the Supreme Court does not recite the underlying facts and holdings is when an equally divided court decides the only issue before the Court. Of course, this is not the circumstance we face today.
HAMILTON, Circuit Judge, concurring in the judgment: As to Hamrick’s convictions' on Counts I, II, III, VI, and VIII, the en banc court affirms these convictions by an equally divided court. In my view, the destructive device convictions having been affirmed by an equally divided court, the sentence enhancement is likewise sustained by an equally divided court. I also agree with the apparent consensus of the entire en banc court that Hamrick’s attacks as to his convictions on Counts IV and V have no merit. In addition, I would affirm Hamrick’s conviction on Count VII on the sole basis that under the Supreme Court’s decision in McLaughlin v. United States, 476 U.S. 16, 106 S.Ct. 1677, 90 L.Ed.2d 15 (1986), the bomb in question constitutes a deadly or dangerous weapon under 18 U.S.C. § 111(b) because a bomb (though dysfunctional) is “typically and characteristically dangerous” and “instills fear in the average citizen.” Id. at 17-18, 106 S.Ct. at 1678. Finally, I add this cautionary note. To the extent that Judge Luttig’s plurality and concurring opinions may be construed to mean that the bomb in question was a destructive device under 18 U.S.C. §§ 921(a)(4) and 924(e)(1) and 26 U.S.C. §§ 6845(f) and 5861, see plurality op. at 881-82 (citing destructive device eases and testimony of government experts), plurality op. at 13 (discussing procedural history of destructive device convictions), and plurality op. at 885-86 (discussing the § 924(c) sentencing enhancement for use of a destructive device), and concurring op. at 886-89 (discussing the testimony of the government experts and the sufficiency of the evidence of the destructive device convictions), such a construction is pure dicta of no precedential value. . No member of this court apparently takes issue with the fact that if the bomb in question was a destructive device, the enhancement should apply. . I cannot join the plurality opinion of Judge Luttig addressing this point because of its unnecessary and unfortunate reliance on cases involving destructive devices and the testimony of the government’s experts regarding whether the bomb in question was capable of detonation. Citation to the destructive device cases is inappropriate for several reasons. First, as this case pellucidly illustrates, our destructive device jurisprudence (namely/ what constitutes a destructive device) is unsettled. Second, these cases offer no guidance whatsoever as to what constitutes a deadly or dangerous weapon under 18 U.S.C. § 111(b). Third, citation to these cases may be construed as an endorsement that the bomb in question was a destructive device, a matter that the court is evenly divided on. Citation to the testimony of the government’s experts regarding the bomb in question's capability of detonation is also, in my view, inappropriate. As the plurality opinion recognizes when it states "the presumption that the bomb sent by Hamrick was dangerous was fully warranted, even though the bomb appears to have been dysfunctional,” plurality op. at 881, the issue under the first two of McLaughlin's three independent rationales is not whether the bomb in question was capable or incapable of detonation. Rather, under the first independent rationale, the questions are whether a bomb in general is typically and characteristically dangerous and the use for which a bomb is manufactured is a dangerous one. Pure common sense tells us that the answer to these inquiries is yes, and, therefore, McLaughlin's first independent rationale is met. As to McLaughlin 's second independent rationale, no showing of capability'of detonation is necessary here because even a dysfunctional bomb, upon display, instills fear in the average citizen. Therefore, this testimony is irrelevant to the dangerous weapon inquiry. . Of course, any view (including my own) that the bomb in question was or was not a destructive device bears no precedential weight because the court affirms the destructive device convictions by an equally divided court. See Arkansas Writers’ Project, Inc. v. Ragland, 481 U.S. 221, 234 n. 7, 107 S.Ct. 1722, 1730 n. 7, 95 L.Ed.2d 209 (1987).
ERVIN, Chief Judge, dissenting: This case presents a straightforward question of statutory construction to determine whether the item Hamrick sent to the United States Attorney falls within the definition of a “deadly or dangerous weapon” pursuant to 18 U.S.C. § 111(b). Beyond the plain meaning of the words Congress employed, neither the statute nor its legislative history offers guidance on this question, a fact the plurality opinion implicitly acknowledges through its act of “borrowing” the jurisprudence of a separate provision of the United States Code. In my view, the plain meaning suffices to convince me that an incomplete bomb lacking an igniter is not a “deadly or dangerous weapon” for purposes of sentence enhancement. Because I do not believe that the borrowed provision is apposite to the statute in question, or that the application of its teaching in this instance leads to the result the plurality believes dictated, I respectfully dissent. I As the plurality opinion notes, the statute in question provides a penalty enhancement for any person who assaults one of a class of current or former federal officers while they are engaged in or on account of the performance of their official duties. Although the maximum statutory penalty for such offense is three years, 18 U.S.C. § 111(a), anyone who uses a “deadly or dangerous weapon” in the commission of such acts is subject to a maximum penalty of ten.years, id. § 111(b). Thus, before a defendant can be eligible for the punishment provided under § 111(b), it is necessary to determine whether the assault involved the use of a “deadly or dangerous weapon.” The role of the courts in cases of statutory construction is to give effect to Congressional intent, Negonsott v. Samuels, — U.S. -, -, 113 S.Ct. 1119, 1122-23, 122 L.Ed.2d 457, 465 (1993); to do more is to transgress the boundaries of the Articles of the Constitution and to engage ourselves as legislators rather than jurists, to allow ourselves to say what we think the law is, or ought to be, rather than what Congress has told us it is. While this temptation hangs always before the judiciary as a tantalizing fruit, it is to us constitutionally forbidden. Because our concern is to carry out that which Congress has wrought, in determining whether any action or situation falls within the borders of the class of activities Congress intended to reach through statutory prohibition we begin with the words of the statute itself, for if they are clear and unambiguous, the task of the courts is ended. Estate of Cowart v. Nicklos Drilling Co., — U.S. -, -, 112 S.Ct. 2589, 2594, 120 L.Ed.2d 379, 388 (1992); United States v. Turkette, 452 U.S. 576, 580, 101 S.Ct. 2524, 2527, 69 L.Ed.2d 246 (1981); United States v. Southern Mgt. Corp., 955 F.2d 914, 920 (4th Cir.1992). Where the intent of Congress is not clear, we must reach for traditional tools of statutory construction to assist us in elucidating, but never extending or supplanting, Congressional intention as to the scope of the statute in question. Public Citizen v. United States Dep’t of Justice, 491 U.S. 440, 453-55, 109 S.Ct. 2558, 2566-67, 105 L.Ed.2d 377 (1989); Gray v. Director, OWCP, 943 F.2d 513, 516 (4th Cir.1991). The enhanced penalty applies t
