Opinions

Mr. Justice Blackmun

delivered the opinion of the Court.

This case presents the issue whether knowledge that the intended victim is a federal officer is a requisite for the crime of conspiracy, under 18 U. S. C. § 371, to commit an offense violative of 18 U. S. C. § 111,¹ that is, an assault upon a federal officer while engaged in the performance of his official duties.

Respondent Feola and three others (Alsondo, Rosa, and Farr) were indicted for violations of §§ 371 and 111. A jury found all four defendants guilty of both charges.² Feola received a sentence of four years for the conspiracy and one of three years, plus a $3,000 fine, for the assault. The three-year sentence, however, was suspended and he was given three years’ probation “to commence at the expiration of confinement” for the conspiracy. The respective appeals of Feola, Alsondo, and Rosa were considered by the United States Court of Appeals for the Second Circuit in a single opinion. After an initial ruling partially to the contrary, that court affirmed the judgment of conviction on the substantive charges, but reversed the conspiracy convictions. United States v. Alsondo, 486 F. 2d 1339, 1346 (1973).³ Because of a conflict among the federal Circuits on the scienter issue with respect to a conspiracy charge,⁴ we granted the Government’s petition for a writ of certiorari in Feola’s case.⁵ 416 U. S. 935 (1974).

I

The facts reveal a classic narcotics “rip-off.” The details are not particularly important for our present purposes. We need note only that the evidence shows that Feola and his confederates arranged for a sale of heroin to buyers who turned out to be undercover agents for the Bureau of Narcotics and Dangerous Drugs. The group planned to palm off on the purchasers, for a substantial sum, a form of sugar in place of heroin and, should that ruse fail, simply to surprise their unwitting buyers and relieve them of the cash they had brought along for payment. The plan failed when one agent, his suspicions being aroused,⁶ drew his revolver in time to counter an assault upon another agent from the rear. Instead of enjoying the rich benefits of a successful swindle, Feola and his associates found themselves charged, to their undoubted surprise, with conspiring to assault, and with assaulting, federal officers.

At the trial, the District Court, without objection from the defense, charged the jurors that, in order to find any of the defendants guilty on either the conspiracy count or the substantive one, they were not required to conclude that the defendants were aware that their quarry were federal officers.⁷

The Court of Appeals reversed the conspiracy convictions on a ground not advanced by any of the defendants. Although it approved the trial court’s instructions to the jury on the substantive charge of assaulting a federal officer,⁸ it nonetheless concluded that the failure to charge that knowledge of the victim’s official identity must be proved in order to convict on the conspiracy charge amounted to plain error. 486 F. 2d, at 1344. The court perceived itself bound by a line of cases, commencing with Judge Learned Hand’s opinion in United States v. Crimmins, 123 F. 2d 271 (CA2 1941), all holding that scienter of a factual element that confers federal jurisdiction, while unnecessary for conviction of the substantive offense, is required in order to sustain a conviction for conspiracy to commit the substantive offense. Although the court noted that the Crimmins rationale “has been criticized,” 486 F. 2d, at 1343, and, indeed, offered no argument in support of it, it accepted “the controlling precedents somewhat reluctantly.” Id., at

The Government’s plea is for symmetry. It urges that since criminal liability for the offense described in 18 U. S. C. § 111 does not depend on whether the assailant harbored the specific intent to assault a federal officer, no greater scienter requirement can be engrafted upon the conspiracy offense, which is merely an agreement to commit the act proscribed by § 111. Consideration of the Government’s contention requires us preliminarily to pass upon its premise, the proposition that responsibility for assault upon a federal officer does not depend upon whether the assailant was aware of the official identity of his victim at the time he acted.

That the “federal officer” requirement is anything other than jurisdictional⁹ is not seriously urged upon us; indeed, both Feola¹⁰ and the Court of Appeals, 486 F. 2d, at 1342, concede that scienter is not a necessary element of the substantive offense under § 111. Although some early cases were to the contrary,¹¹ the concession recognizes what is now the practical unanimity of the Courts of Appeals.¹² Nevertheless, we are not always guided by concessions of the parties, and the very considerations of symmetry urged by the Government suggest that we first turn our attention to the substantive offense.

The Court has considered § 111 before. In Ladner v. United States, 358 U. S. 169 (1958), the issue was whether a single shotgun blast which wounded two federal agents effected multiple assaults, within the meaning of 18 U. S. C. § 254 (1940 ed.), one of the statutory predecessors to the present § 111.¹³ The Government urged that § 254 had been intended not only to deter interference with federal law enforcement activities but, as well, to forestall injury to individual officers, as “wards” of the United States. Given the latter formulation of legislative intent, argued the Government, a single blast wounding two officers would constitute two offenses. The Court disagreed because it found an equally plausible reading of the legislative intent to be that “the congressional aim was to prevent hindrance to the execution of official duty . . . and was not to protect federal officers except as incident to that aim,” 358 U. S., at 175-176. Under that view of legislative purpose, to have punishment depend upon the number of officers impeded would be incongruous. With no clear choice between these alternative formulations of congressional intent, in light of the statutory language and sparse legislative history, the Court applied a policy of lenity and, for purposes of the case, adopted the less harsh reading. Id., at 177-178. It therefore held that the single discharge of a shotgun constituted only a single violation of § 254.

In the present case, we see again the possible consequences of an interpretation of § 111 that focuses on only one of the statute’s apparent aims. If the primary purpose is to protect federal law enforcement personnel, that purpose could well be frustrated by the imposition of a strict scienter requirement. On the other hand, if § 111 is seen primarily as an anti-obstruction statute, it is likely that Congress intended criminal liability to be imposed only when a person acted with the specific intent to impede enforcement activities. Otherwise, it has been said: “Were knowledge not required in obstruction of justice offenses described by these terms, wholly innocent (or even socially desirable) behavior could be transformed into a felony by the wholly fortuitous circumstance of the concealed identity of the person resisted.” ¹⁴ Although we adhere to the conclusion in Ladner that either view of legislative intent is “plausible,” we think it plain that Congress intended to protect both federal officers and federal functions, and that, indeed, furtherance of the one policy advances the other. The rejection of a strict scienter requirement is consistent with both purposes.

Section 111 has its origin in § 2 of the Act of May 18, 1934, c. 299, 48 Stat. 781. Section 1 of that Act, in which the present 18 U. S. C. § 1114 has its roots, made it a federal crime to kill certain federal law enforcement personnel while engaged in, or on account of, the performance of official duties,¹⁵ and § 2 forbade forcible resistance or interference with, or assault upon, any officer designated in § 1 while so engaged. The history of the 1934 Act, though scanty, offers insight into its multiple purposes. The pertinent committee reports consist, almost in their entirety, of a letter dated January 3, 1934, from Attorney General Cummings urging the passage of the legislation.¹⁶ In that letter the Attorney General states that this was needed “for the protection of Federal officers and employees.” Compelled reliance upon state courts, “however respectable and well disposed, for the protection of [federal] investigative and law-enforcement personnel” was inadequate, and there was need for resort to a federal forum.

Although the letter refers only to the need to protect federal personnel, Congress clearly was concerned with the safety of federal officers insofar as it was tied to the efficacy of law enforcement activities. This concern is implicit in the decision to list those officers protected rather than merely to forbid assault on any federal employee. Indeed, the statute as originally formulated would have prohibited attack on “any civil official, inspector, agent, or other officer or employee of the United States.” See H. R. Rep. No. 1455, 73d Cong., 2d Sess., 1 (1934). The House rejected this and insisted on the version that was ultimately enacted. Although the reason for the insistence is unexplained, it is fair to assume that the House was of the view that the bill as originally drafted strayed too far from the purpose of insuring the integrity of law enforcement pursuits.¹⁷

In resolving the question whether Congress intended to condition responsibility for violation of § 111 on the actor’s awareness of the identity of his victim, we give weight to both purposes of the statute, but here again, as in Ladner, we need not make a choice between them. Rather, regardless of which purpose we would emphasize, we must take note of the means Congress chose for its achievement.

Attorney General Cummings, in his letter, emphasized the importance of providing a federal forum in which attacks upon named federal officers could be prosecuted. This, standing alone, would not indicate a congressional conclusion to dispense with a requirement of specific intent to assault a federal officer, for the locus of the forum does not of itself define the reach of the substantive offense. But the view that § 111 requires knowledge of the victim’s office rests on the proposition that the reference to the federal forum was merely a shorthand expression of the need for a statute to fill a gap in the substantive law of the States. See United States v. Fernandez, 497 F. 2d 730, 745 (CA9 1974) (concurring opinion), cert. pending, No. 73-6868. In that view, § 111 is seen merely as a federal aggravated assault statute, necessary solely because some state laws mandate increased punishment only for assaults on state peace officers; assaults on federal personnel would be punishable, under state law, only for simple assault. As a federal aggravated assault statute, § 111 would be read as requiring the same degree of knowledge as its state-law counterparts. See Morissette v. United States, 342 U. S. 246, 263 (1952). The argument fails, however, because it is fairly certain that Congress was not enacting § 111 as a federal counterpart to state proscriptions of aggravated assault.

The Attorney General’s call for a federal forum in which to prosecute an attacker of a federal officer was directed at both sections of the proposed bill that became the 1934 Act. The letter concerned not only the section prohibiting assaults but also the section prohibiting killings. The latter, § 1, was not needed to fill a gap in existing substantive state law. The States proscribed murder, and, until recently, with the enactment of certain statutes in response to the successful attack on capital punishment, murder of a peace officer has not been deemed an aggravated form of murder, for all States usually have punished murderers with the most severe sanction the law allows. Clearly, then, Congress understood that it was not only filling one gap in state substantive law but in large part was duplicating state proscriptions in order to insure a federal forum for the trial of offenses involving federal officers. Fulfillment of the congressional goal to protect federal officers required then, as it does now, the highest possible degree of certainty that those who killed or assaulted federal officers were brought to justice. In the congressional mind, with the reliance upon the Attorney General’s letter, certainty required that these cases be tried in the federal courts, for no matter how “respectable and well disposed,” it would not be unreasonable to suppose that state officials would not always or necessarily share congressional feelings of urgency as to the necessity of prompt and vigorous prosecutions of those who violate the safety of the federal officer. From the days of prohibition to the days of the modern civil rights movement, the statutes federal agents have sworn to uphold and enforce have not always been popular in every corner of the Nation. Congress may well have concluded that § 111 was necessary in order to insure uniformly vigorous protection off federal personnel, including those engaged in locally unpopular activity.

We conclude, from all this, that in order to effectuate the congressional purpose of according maximum protection to federal officers by making prosecution for assaults upon them cognizable in the federal courts, § 111 cannot be construed as embodying an unexpressed requirement that an assailant be aware that his victim is a federal officer. All the statute requires is an intent to assault, not an intent to assault a federal officer. A contrary conclusion would give insufficient protection to the agent enforcing an unpopular law, and none to the agent acting under cover.¹⁸

This interpretation poses no risk of unfairness to defendants. It is no snare for the unsuspecting. Although the perpetrator of a narcotics “rip-off/¹ such as the one involved here, may be surprised to find that his intended victim is a federal officer in civilian apparel, he nonetheless knows from the very outset that his planned course of conduct is wrongful. The situation is not one where legitimate conduct becomes unlawful solely because of the identity of the individual or agency affected. In a case of this kind the offender takes his victim as he finds him. The concept of criminal intent does not extend so far as to require that the actor understand not only the nature of his act but also its consequence for the choice of a judicial forum.

We are not to be understood as implying that the defendant’s state of knowledge is never a relevant consideration under § 111. The statute does require a criminal intent, and there may well be circumstances in which ignorance of the official status of the person assaulted or resisted negates the very existence of mens rea. For example, where an officer fails to identify himself or his purpose, his conduct in certain circumstances might reasonably be interpreted as the unlawful use of force directed either at the defendant or his property. In a situation of that kind, one might be justified in exerting an element of resistance, and an honest mistake of fact would not be consistent with criminal intent.¹⁹

We hold, therefore, that in order to incur criminal liability under § 111 an actor must entertain merely the criminal intent to do the acts therein specified. We now consider whether the rule should be different where persons conspire to commit those acts.

Ill

Our decisions establish that in order to sustain a judgment of conviction on a charge of conspiracy to violate a federal statute, the Government must prove at least the degree of criminal intent necessary for the substantive offense itself. Ingram v. United States, 360 U. S. 672, 678 (1969). See Pettibone v. United States, 148 U. S. 197 (1893). Respondent Feola urges upon us the proposition that the Government must show a degree of criminal intent in the conspiracy count greater than is necessary to convict for the substantive offense; he urges that even though it is not necessary to show that he was aware of the official identity of his assaulted victims in order to find him guilty of assaulting federal officers, in violation of 18 U. S. C. § 111, the Government nonetheless must show that he was aware that his intended victims were undercover agents, if it is successfully to prosecute him for conspiring to assault federal agents. And the Court of Appeals held that the trial court’s failure to charge the jury to this effect constituted plain error.

The general conspiracy statute, 18 U. S. C. § 371,²⁰ offers no textual support for the proposition that to be guilty of conspiracy a defendant in effect must have known that his conduct violated federal law. The statute makes it unlawful simply to “conspire ... to commit any offense against the United States.” A . natural reading of these words would be that since one can violate a criminal statute simply by engaging in the forbidden conduct, a conspiracy to commit that offense is nothing more than an agreement to engage in the prohibited conduct. Then where, as here, the substantive statute does not require that an assailant know the official status of his victim, there is nothing on the face of the conspiracy statute that would seem to require that those agreeing to the assault have a greater degree of knowledge.

We have been unable to find any decision of this Court that lends support to the respondent. On the contrary, at least two of our cases implicitly repudiate his position. The appellants in In re Coy, 127 U. S. 731 (1888), were convicted of conspiring to induce state election officials to neglect their duty to safeguard ballots and election results. The offense occurred with respect to an election at which Indiana voters, in accordance with state law, voted for both local officials and members of Congress. Much like Feola here, those appellants asserted that they could not be punished for conspiring to violate federal law because they had intended only to affect the outcome of state races. In short, it was urged that the conspiracy statute embodied a requirement of specific intent to violate federal law. Id., at 753. The Court rejected this contention and held that the statute required only that the conspirators agree to participate in the prohibited conduct. See Anderson v. United States, 417 U. S. 211, 226 (1974).

Similarly, in United States v. Freed, 401 U. S. 601 (1971), we reversed the dismissal of an indictment charging defendants with possession of, and with conspiracy to possess, hand grenades that had not been registered, as required by 26 U. S. C. § 5861 (d). The trial court dismissed the indictment for failure to allege that the defendants knew that the hand grenades in fact were unregistered. We held that actual knowledge that the grenades were unregistered was not an element of the substantive offense created by Congress and therefore upheld the indictment both as to the substantive offense and as to the charge of conspiracy. Again, we declined to require a greater degree of intent for conspiratorial responsibility than for responsibility for the underlying substantive offense.

With no support on the face of the general conspiracy statute or in this Court’s decisions, respondent relies solely on the line of cases commencing with United States v. Crimmins, 123 F. 2d 271 (CA2 1941), for the principle that the Government must prove “antifederal” intent in order to establish liability under § 371. In Crimmins, the defendant had been found guilty of conspiring to receive stolen bonds that had been transported in interstate commerce. Upon review, the Court of Appeals pointed out that the evidence failed to establish that Crimmins actually knew the stolen bonds had moved into the State. Accepting for the sake of argument the assumption that such knowledge was not necessary to sustain a conviction on the substantive offense, Judge Learned Hand nevertheless concluded that to permit conspiratorial liability where the conspirators were ignorant of the federal implications of their acts would be to enlarge their agreement beyond its terms as they understood them. He capsulized the distinction in what has become well known as his “traffic light” analogy:

“While one may, for instance, be guilty of running past a traffic light of whose existence one is ignorant, one cannot be guilty of conspiring to run past such a light, for one cannot agree to run past a light unless one supposes that there is a light to run past.” Id., at 273.

Judge Hand’s attractive, but perhaps seductive, analogy has received a mixed reception in the Courts of Appeals. The Second Circuit, of course, has followed it;²¹ others have rejected it.²² It appears that most have avoided it by the simple expedient of inferring the requisite knowledge from the scope of the conspiratorial venture.²³ We conclude that the analogy, though effective prose, is, as applied to the facts before us, bad law.²⁴

The question posed by the traffic light analogy is not before us, just as it was not before the Second Circuit in Crimmins. Criminal liability, of course, may be imposed on one who runs a traffic light regardless of whether he harbored the “evil intent” of disobeying the light’s command; whether he drove so recklessly as to be unable to perceive the light; whether, thinking he was observing all traffic rules, he simply failed to notice the light; or whether, having been reared elsewhere, he thought that the light was only an ornament. Traffic violations generally fall into that category of offenses that dispense with a mem rea requirement. See United States v. Dotterweich, 320 U. S. 277 (1943). These laws embody the social judgment that it is fair to punish one who intentionally engages in conduct that creates a risk to others, even though no risk is intended or the actor, through no fault of his own, is completely unaware of the existence of any risk. The traffic light analogy poses the question whether it is fair to punish parties to an agreement to engage intentionally in apparently innocent conduct where the unintended result of engaging in that conduct is the violation of a criminal statute.

But this case does not call upon us to answer this question, and we decline to do so, just as we have once before. United States v. Freed, 401 U. S., at 609 n. 14. We note in passing, however, that the analogy comes close to stating what has been known as the “Powell doctrine,” originating in People v. Powell, 63 N. Y. 88 (1875),'to the effect that a conspiracy, to be criminal, must be animated by a corrupt motive or a motive to do wrong. Under this principle, such a motive could be easily demonstrated if the underlying offense involved an act clearly wrongful in itself; but it had to be independently demonstrated if the acts agreed to were wrongful solely because of statutory proscription. See Note, Developments in the Law — Criminal Conspiracy, 72 Harv. L. Rev. 920, 936-937 (1959). Interestingly, Judge Hand himself was one of the more severe critics of the Powell doctrine.²⁵

That Judge Hand should reject the Powell doctrine and then create the Crimmins doctrine seems curious enough. Fatal to the latter, however, is the fact that it was announced in a case to which it could not have been meant to apply. In Crimmins, the substantive offense, namely, the receipt of stolen securities that had been in interstate commerce, proscribed clearly wrongful conduct. Such conduct could not be engaged in without an intent to accomplish the forbidden result. So, too, it is with assault, the conduct forbidden by the substantive statute, § 111, presently before us. One may run a traffic light “of whose existence one is ignorant,” but assaulting another “of whose existence one is ignorant,” probably would require unearthly intervention. Thus, the traffic light analogy, even if it were a correct statement of the law, is inapt, for the conduct proscribed by the substantive offense, here assault, is not of the type outlawed without regard to the intent of the actor to accomplish the result that is made criminal. If the analogy has any vitality at all, it is to conduct of the latter variety; that, however, is a question we save for another day. We hold here only that where a substantive offense embodies only a requirement of mens rea, as to each of its elements, the general federal conspiracy statute requires no more.

The Crimmins rule rests upon another foundation: that it is improper to find conspiratorial liability where the parties to the illicit agreement were not aware of the fact giving rise to federal jurisdiction, because the essence of conspiracy is agreement and persons cannot be punished for acts beyond the scope of their agreement. 123 F. 2d, at 273. This “reason” states little more than a conclusion, for it is clear that one may be guilty as a conspirator for acts the precise details of which one does not know at the time of the agreement. See Blumenthal v. United States, 332 U. S. 539, 557 (1947). The question is not merely whether the official status of an assaulted victim was known to the parties at the time of their agreement, but whether the acts contemplated by the conspirators are to be deemed legally different from those actually performed solely because of the official identity of the victim. Put another way, does the identity of the proposed victim alter the legal character of the acts agreed to, or is it no more germane to the nature of those acts than the color of the victim’s hair?

Our analysis of the substantive offense in Part II, supra, is sufficient to convince us that for the purpose of individual-guilt or innocence, awareness of the official identity of the assault victim is irrelevant. We would expect the same to obtain with respect to the conspiracy offense unless one of the policies behind the imposition of conspiratorial liability is not served where the parties to the agreement are unaware that the intended target is a federal law enforcement official.

It is well settled that the law of conspiracy serves ends different from, and complementary to, those served by criminal prohibitions of the substantive offense. Because of this, consecutive sentences may be imposed for the conspiracy and for the underlying crime. Callanan v. United States, 364 U. S. 587 (1961); Pinkerton v. United States, 328 U. S. 640 (1946). Our decisions have identified two independent values served by the law of conspiracy. The first is protection of society from the dangers of concerted criminal activity, Callanan v. United States, 364 U. S., at 593; Dennis v. United States, 341 U. S. 494, 573-574 (1951) (Jackson, J., concurring). That individuals know that their planned joint venture violates federal as well as state law seems totally irrelevant to that purpose of conspiracy law which seeks to protect society from the dangers of concerted criminal activity. Given the level of criminal intent necessary to sustain conviction for the substantive offense, the act of agreement to commit the crime is no less opprobrious and no less dangerous because of the absence of knowledge of a fact unnecessary to the formation of criminal intent. Indeed, unless imposition of an “antifederal” knowledge requirement serves social purposes external to the law of conspiracy of which we are unaware, its imposition here would serve only to make it more difficult to obtain convictions on charges of conspiracy, a policy with no apparent purpose.

The second aspect is that conspiracy is an inchoate crime. This is to say, that, although the law generally makes criminal only antisocial conduct, at some point in the continuum between preparation and consummation, the likelihood of a commission of an act is sufficiently great and the criminal intent sufficiently well formed to justify the intervention of the criminal law. See Note, Developments in the Law — Criminal Conspiracy, 72 Harv. L. Rev., at 923-925. The law of conspiracy identifies the agreement to engage in a criminal venture as an event of sufficient threat to social order to permit the imposition of criminal sanctions for the agreement alone, plus an overt act in pursuit of it, regardless of whether the crime agreed upon actually is committed. United States v. Bayer, 331 U. S. 532, 542 (1947). Criminal intent has crystallized, and the likelihood of actual, fulfilled commission warrants preventive action.

Again, we do not see how imposition of a strict “anti-federal” scienter requirement would relate to this purpose of conspiracy law. Given the level of intent needed to carry out the substantive offense, we fail to see how the agreement is any less blameworthy or constitutes less of a danger to society solely because the participants are unaware which body of law they intend to violate. Therefore, we again conclude that imposition of a requirement of knowledge of those facts that serve only to establish federal jurisdiction would render it more difficult to serve the policy behind the law of conspiracy without serving any other apparent social policy.

We hold, then, that assault of a federal officer pursuant to an agreement to assault is not, even in the words of Judge Hand, “beyond the reasonable intendment of the common understanding,” United States v. Crimmins, 123 F. 2d, at 273. The agreement is not thereby enlarged, for knowledge of the official identity of the victim is irrelevant to the essential nature of the agreement, entrance into which is made criminal by the law of conspiracy.

Again we point out, however, that the state of knowledge of the parties to an agreement is not always irrelevant in a proceeding charging a violation of conspiracy law. First, the knowledge of the parties is relevant to the same issues and to the same extent as it may be for conviction of the substantive offense. Second, whether conspirators knew the official identity of their quarry may be important, in some cases, in establishing the existence of federal jurisdiction. The jurisdictional requirement is satisfied by the existence of facts tying the proscribed conduct to the area of federal concern delineated by the statute. Federal jurisdiction always exists where the substantive offense is committed in the manner therein described, that is, when a federal officer is attacked. Where, however, there is an unfulfilled agreement to assault, it must be established whether the agreement, standing alone, constituted a sufficient threat to the safety of a federal officer so as to give rise to federal jurisdiction. If the agreement calls for an attack on an individual specifically identified, either by name or by some unique characteristic, as the putative buyers in the present case, and that specifically identified individual is in fact a federal officer, the agreement may be fairly characterized as one calling for an assault upon a federal officer, even though the parties were unaware of the victim's actual identity and even though they would not have agreed to the assault had they known that identity. Where the object of the intended attack is not identified with sufficient specificity so as to give rise to the con-elusion that had the attack been carried out the victim would have been a federal officer, it is impossible to assert that the mere act of agreement to assault poses a sufficient threat to federal personnel and functions so as to give rise to federal jurisdiction.

To summarize, with the exception of the infrequent situation in which reference to the knowledge of the parties to an illegal agreement is necessary to establish the existence of federal jurisdiction, we hold that where knowledge of the facts giving rise to federal jurisdiction is not necessary for conviction of a substantive offense embodying a mens rea requirement, such knowledge is equally irrelevant to questions of responsibility for conspiracy to commit that offense.

The judgment of the Court of Appeals with respect to the respondent’s conspiracy conviction is reversed.

It is so ordered.

1 "§ 111. Assaulting, resisting, or impeding certain officers or employees.

“Whoever forcibly assaults, resists, opposes, impedes, intimidates, or interferes with any person designated in section 1114 of this title while engaged in or on account of the performance of his official duties, shall be fined not more than $5,000 or imprisoned not more than three years, or both.

“Whoever, in the commission of any such acts uses a deadly or dangerous weapon, shall be fined not more than $10,000 or imprisoned not more than ten years, or both.”

Among the persons “designated in section 1114” of 18 U. S. C. is “any officer or employee ... of the Bureau of Narcotics and Dangerous Drugs.”

2 Codefendant Alsondo was also convicted of carrying a firearm unlawfully during the commission of the other felonies, in violation of 18 U. S. C. §924 (c)(2).

3 The appeal of the fourth defendant, Farr, was processed separately by the Court of Appeals. A different panel, upon the authority of Alsondo, similarly affirmed the judgment of conviction on the substantive charge but reversed the conspiracy conviction. United States v. Farr, 487 F. 2d 1023 (CA2 1973), cert. pending, No. 73-953. The District Court imposed concurrent sentences in Farr’s case, and the United States has not sought review here.

4 See, e. g., United States v. Iannelli, 477 F. 2d 999, 1002 (CA3 1973), cert. granted on another issue, 417 U. S. 907 (1974); United States v. Thompson, 476 F. 2d 1196, 1198-1200 (CA7), cert. denied, 414 U. S. 918 (1973); United States v. Polesti, 489 F. 2d 822, 824 (CA7 1973), cert. pending, No. 73-5489; United States v. Roselli, 432 F. 2d 879, 891-892 (CA9 1970), cert. denied, 401 U. S. 924 (1971); United States v. Fernandez, 497 F. 2d 730, 738-739 (CA9 1974), cert. pending, No. 73-6868.

5 The sentence imposed on codefendants Alsondo and Rosa possessed elements of concurrency and the United States did not petition for a writ of certiorari in their cases.

6 The agent opened a closet door in the Manhattan apartment where the sale was to have taken place and observed a man on the floor, bound and gagged. App. 11-12.

7 The court charged:

“In this connection, it is not necessary for the government to prove that the defendants or any of them knew that the persons they were going to assault or impede or resist were federal agents. It’s enough, as far as this particular element of the case is concerned, for the government to prove that the defendants agreed and conspired to commit an assault.” Tr. 513.

“I believe I have previously mentioned to you that the statute does not require that the defendant know either the identity of the person assaulted or imped[ed] or intimidated or that the person assaulted is a federal officer.” Id., at 525.

8 The Second Circuit consistently has so held. See, e. g., United States v. Lombardozzi, 335 F. 2d 414, 416, cert. denied, 379 U. S. 914 (1964); United States v. Montanaro, 362 F. 2d 527, 528, cert. denied, 385 U. S. 920 (1966); United States v. Ulan, 421 F. 2d 787, 788 (1970).

9 We are content to state the issue this way despite its potential to mislead. Labeling a requirement “jurisdictional” does not necessarily mean, of course, that the requirement is not an element of the offense Congress intended to describe and to punish. Indeed, a requirement is sufficient to confer jurisdiction on the federal courts for what otherwise are state crimes precisely because it implicates factors that are an appropriate subject for federal concern. With respect to the present case, for example, a mere general policy of deterring assaults would probably prove to be an undesirable or insufficient basis for federal jurisdiction; but where Congress seeks to protect the integrity of federal functions and the safety of federal officers, the interest is sufficient to warrant federal involvement. The significance of labeling a statutory requirement as “jurisdictional” is not that the requirement is viewed as outside the scope of the evil Congress intended to forestall, but merely that the existence of the fact that confers federal jurisdiction need not be one in the mind of the actor at the time he perpetrates the act made criminal by the federal statute. The question, then, is not whether the requirement is jurisdictional, but whether it is jurisdictional only.

15 Section 1 provided:

“That whoever shall kill, as defined in sections 273 and 274 of the Criminal Code, any United States marshal or deputy United States marshal, special agent of the Division of Investigation of the Department of Justice, post-office inspector, Secret Service operative, any officer or enlisted man of the Coast Guard, any employee of any United States penal or correctional institution, any officer of the customs or of the internal revenue, any immigrant inspector or any immigration patrol inspector, while engaged in the performance of his official duties, or on account of the performance of his official duties, shall be punished as provided under section 275 of the Criminal Code.” C. 299, 48 Stat. 780.

A glance at the present § 1114 reveals how the list of protected federal officers has been greatly expanded. Plainly, some of those now named, viz., “employee of the Postal Service” and “employee of the National Park Service,” are not necessarily engaged in the execution of federal law.

The Attorney General’s letter was addressed to Senator Ashurst, Chairman of the Senate Committee on the Judiciary, and read in full as follows:

“My Dear SeNator: I wish again to renew the recommendation of this Department that legislation be enacted making it a Federal offense forcibly to resist, impede, or interfere with, or to assault or kill, any official or employee of the United States while engaged in, or on account of, the performance of his official duties. Congress has already made it a Federal offense to assault, resist, etc., officers or employees of the Bureau of Animal Industry of the Department of Agriculture while engaged in or on account of the execution of their duties (sec. 62, C. C.; sec. 118, title 18, U. S. C.); to assault, resist, etc., officers and others of the Customs and Internal Revenue, while engaged in the execution of their duties (sec. 65, C. C.; sec. 121, title 18, U. S. C.); to assault, resist, beat, wound, etc., any officer of the United States, or other person duly authorized, while serving or attempting to serve the process of any court of the United States (sec. 140, C. C.; sec. 245, title 18, U. S. C.); and to assault, resist, etc., immigration officials or employees while engaged in the performance of their duties (sec. 16, Immigration Act of Feb. 5, 1917, c. 29, 39 Stat. 885; sec. 152, title 8, U. S. C.). Three of the statutes "just cited impose an increased penalty when a deadly or dangerous weapon is used in resisting the officer or employee.

“The need for general legislation of the same character, for the protection of Federal officers and employees other than those specifically embraced in the statutes above cited, becomes increasingly apparent every day. The Federal Government should not be compelled to rely upon the courts of the States, however respectable and well disposed, for the protection of its investigative and law-enforcement personnel; and Congress has recognized this fact at least to the extent indicated by the special acts above cited. This Department has found need for similar legislation for the adequate protection of the special agents of its division of investigation, several of whom have been assaulted in the course of a year, while in the performance of their official duties.

“In these cases resort must usually be had to the local police court, which affords but little relief to us, under the circumstances, in our effort to further the legitimate purposes of the Federal Government. It would seem to be preferable, however, instead of further extending the piecemeal legislation now on the statute books, to enact a broad general statute to embrace all proper cases, both within and outside the scope of existing legislation. Other cases in point are assaults on letter carriers, to cover which the Post Office Department has for several years past sought legislation; and the serious wounding, a couple of years ago, of the warden of the Federal Penitentiary at Leavenworth by escaped convicts outside the Federal jurisdiction. In the latter case it was possible to punish the escaped convicts under Federal law for their escape; but they could not be punished under any Federal law for the shooting of the warden.

“I have the honor, therefore, to enclose herewith a copy of S. 3184, which was introduced at the request of this Department in the Seventy-second Congress and to urge its reintroduction in the present Congress; and to express the hope that it may receive the prompt and serious consideration of your committee.

“Respectfully,

“Homer CummiNgs, “Attorney General.”

17 This conclusion is supported by the wording of § 2 of the 1934 Act (and of the present § 111), for that section outlawed more than assaults. It made it a criminal offense “forcibly [to] resist, oppose, impede, intimidate, or interfere with” the named officials while in the performance of their duty. Statutory language of this type had appeared as early as 1866, in § 6 of the Act of July 18 of that year, 14 Stat. 179, embracing a comprehensive scheme for the prevention of smuggling. The bulk of that statute, to be sure, was concerned with essentially regulatory matters; § 6, however, proscribed a broad range of actions — beyond simple forcible resistance — that would frustrate effective enforcement of the body of the statute. In employing a similar formulation in 1934, Congress could be presumed to be going beyond mere protection of the safety of federal officers without regard to the integrity of their official functions.

18 Some indication that -Congress did not intend to exclude undercover agents from the protection of the statute comes from the inclusion of the term "Secret Service operative” in the list of protected officials in the 1934 Act. In the 1948 revision, that term was replaced by “any officer or employee of the secret service or of the Bureau of Narcotics.” 62 Stat. 756. That Bureau, in 1948 part of the Treasury, has since been abolished and its functions transferred to the Bureau of Narcotics and Dangerous Drugs, the predecessor agency to the present Drug Enforcement Administration. See Reorganization Plan No. 2 of 1973, 38 Fed. Reg. 15932.

Our Brother Stewart in dissent asserts, post, at 705-706, that since only state prohibitions of simple assault deter attack on the undercover agent, it is “nonsense” to hold that Congress concluded that a strict scienter requirement would have given insufficient protection to undercover agents. This argument conveniently ignores § 1 of the 1934 Act, the homicide prohibition. Certainly prior to 1934 all States outlawed murder, and if the congressional judgment that there was need to prosecute in federal courts assaults upon federal officers regardless of the reach of state law was “nonsense,” enactment of the homicide prohibition — completely duplicating the coverage of state statutes — was legislative fatuity. It is more plausible, we think, to conclude that Congress chose not to entrust to the States sole responsibility for the interdiction of attacks, fatal or not, upon federal law enforcement officials — a matter essential to the morale of all federal law enforcement personnel and central to the efficacy of federal law enforcement activities. The dissent would have us conclude that Congress silently chose to treat assaults and homicides differently; but we have before us one bill with a single legislative history, and we decline to bifurcate our interpretation.

20 Title 18 U. S. C. § 371 provides:

“If two or more persons conspire either to commit any offense against the United States, or to defraud the United States, or any agency thereof in any manner or for any purpose, and one or more of such persons do any act to effect the object of the conspiracy, each shall be fined not more than $10,000 or imprisoned not more than five years, or both.”

What little commentary the Crimmins rule has attracted has been uniformly critical. See Note, Developments in the Law — Criminal Conspiracy, 72 Harv. L. Rev. 920, 937-940 (1959); Model Penal Code § 5.03 (Tent. Draft No. 10, 1960); 1 Working Papers of the National Commission on Reform of Federal Criminal Laws 388-389 (1970); Final Report of the National Commission on Reform of Federal Criminal Laws §§ 203, 204, and 1004 (1971).

24 The Government rather effectively exposes the fallacy of the Crimmins traffic light analogy by recasting it in terms of a jurisdictional element. The suggested example is a traffic light on an Indian reservation. Surely, one may conspire with others to disobey the light but be ignorant of the fact that it is on the reservation. As applied to a jurisdictional element of this kind the formulation makes little sense.

25 “Starting with People v. Powell . . . the anomalous doctrine has indeed gained some footing in the circuit courts of appeals that for conspiracy there must be a ‘corrupt motive. . . .’ Yet it is hard to see any reason for this, or why more proof should be necessary than that the parties had in contemplation all the elements of the crime they are charged with conspiracy to commit.” United States v. Mack, 112 F. 2d 290, 292 (CA2 1940).

1 "Whoever forcibly assaults, resists, opposes, impedes, intimidates, or interferes with any person designated in section 1114 of this title while engaged in or on account of the performance of his official duties, shall be fined not more than $5,000 or imprisoned not more than three years, or both.

“Whoever, in the commission of any such acts uses a deadly or dangerous weapon, shall be fined not more than $10,000 or imprisoned not more than ten years, or both.”
