OPINION
This case presents the question of whether a newly-enacted federal statuteâ 18 U.S.C. § 4248 (2006) â lies within Congressâs power. Section 4248 purports to *276 allow the federal government to place in indefinite civil commitment âsexually dangerousâ persons, granting the federal government unprecedented authority over civil commitment â an area long controlled by the states. The district court held that § 4248 exceeds the limits of congressional power and intrudes on the powers reserved to the states. The Government now appeals.
We are the first appellate court to address this question, but the issue has divided trial courts across the nation. Compare. United States v. Tom, 558 F.Supp.2d 931, 938, 941 (D.Minn.2008) (holding that Congress lacked authority to enact § 4248), and United States v. Comstock, 507 F.Supp.2d 522, 540 (E.D.N.C.2007) (same), with United States v. Abregana, 574 F.Supp.2d 1123, 1133-34 (D.Haw.2008) (holding that Congress had authority to enact § 4248), United States v. Dowell, No. CIV-06-1216-D, 2007 WL 5361304, at *7 (W-D.Okla. Dec.5, 2007) (same), United States v. Shields, 522 F.Supp.2d 317, 328 (D.Mass.2007) (same), and United States v. Carta, 503 F.Supp.2d 405, 407-08 (D.Mass.2007) (same).
Two fundamental principles guide our inquiry. On one hand, respect for the legislative branch demands that we afford congressional enactments a âpresumption of constitutionality.â United States v. Morrison, 529 U.S. 598, 607, 120 S.Ct. 1740, 146 L.Ed.2d 658 (2000). But on the other, we must invalidate an act of Congress on a âplain showingâ that Congress has exceeded its constitutional authority. Id.
After carefully considering the Governmentâs arguments, we conclude, for the reasons set forth below, that § 4248 does indeed lie beyond the scope of Congressâs authority. The Constitution does not empower the federal government to confine a person solely because of asserted âsexual dangerousnessâ when the Government need not allege (let alone prove) that this âdangerousnessâ violates any federal law. We therefore affirm the judgment of the district court. 1
I.
A.
Congress enacted § 4248 as part of the Adam Walsh Child Protection and Safety Act of 2006 (âthe Actâ). See Pub.L. No. 109-248, § 302, 120 Stat. 587, 620-22. With the aim of âprotect[ing] children from sexual exploitation and violent crime,â id. at 587, a Senate sponsor described the Act as âthe most comprehensive child crimes and protection bill in our Nationâs history.â 152 Cong. Rec. S8012 (daily ed. July 20, 2006) (statement of Sen. Hatch). Among other measures, the Act creates a National Sex Offender Registry, see § 119, 120 Stat. at 596 (codified at 42 U.S.C. § 16919 (2006)), increases punishments for a variety of federal crimes against children, see, e.g., § 206, 120 Stat. at 613 (codified as amended at 18 U.S.C. § 2241 (2006)), and strengthens existing child pornography prohibitions, see, e.g., § 506, 120 Stat. at 630-31 (codified as amended at 18 U.S.C. § 1465 (2006)). None of these provisions of the Act is challenged here.
The only portion of the Act at issue here, § 4248, authorizes the federal government to civilly commit, in a federal facility, any âsexually dangerousâ person âin the custodyâ of the Bureau of Prisons â even after that person has completed his entire prison sentence. 18 U.S.C. *277 § 4248(a), (d) (2006). To initiate commitment under § 4248, the Attorney General need only certify that a person within federal custody is âsexually dangerous.â Such a certification, when filed with the district court in the jurisdiction in which the federal government holds a person, automatically stays that personâs release from prison. Id. § 4248(a). In the cases at issue here, this stay has extended federal confinement well past the end of any prison term. Thus, pursuant to § 4248, the federal government has civilly confined former federal prisoners without proof that they have committed any new offense. Moreover, § 4248 empowers the Attorney General to prolong federal detention in this manner without presenting evidence or making any preliminary showing; the statute only requires that the certification contain an allegation of dangerousness.
The statute defines a âsexually dangerous personâ to be one who âhas engaged or attempted to engage in sexually violent conduct or child molestation and who is sexually dangerous to others,â and who suffers from a severe mental illness such that he would âhave serious difficulty in refraining from sexually violent conduct or child molestation if released.â 18 U.S.C. § 4247(a)(5)-(6) (2006). However, neither âsexually violent conductâ nor âchild molestationâ are terms defined by the statute. 2
After the Attorney General files the certification, § 4248 directs the district court to adjudicate a personâs alleged sexual dangerousness. Id. § 4248(a). If the district court finds the person to be sexually dangerous by clear and convincing evidence, the court must commit the person to federal custody. Id. § 4248(d). Only then does § 4248 direct the Attorney General to make âall reasonable effortsâ to transfer responsibility for the person to an appropriate state authority. Id. Unless and until a state assumes this responsibility, § 4248 authorizes federal confinement for as long as the person remains âsexually dangerous.â Id.
B.
Graydon Comstock, who filed the first of these consolidated challenges to § 4248, pled guilty to receipt of child pornography in violation of 18 U.S.C. § 2252(a)(2) (2006). Six days prior to the end of his 37-month prison sentence, the Attorney General certified Comstock as a sexually dangerous person, staying his release from prison. More than two years later, Com-stock remains confined in the medium security Federal Correctional Institution at Butner, North Carolina (âFCI-Butnerâ).
The cases of Markis Revland, Thomas Matherly, and Marvin Vigil followed a similar course, with the Government certifying each man for federal commitment less than one month before he completed his full prison term. 3 In fact, the Government *278 certified Vigil for civil commitment on the very same day that he had completed his 96-month term of imprisonment. Like Comstock, each of these men remains in federal custody at FCI-Butner more than two years after the expiration of his prison term.
As part of each certification, the Government petitioned for a hearing to determine whether the named person qualified as âsexually dangerousâ under § 4248. In each case, the named person then moved to dismiss, contending that § 4248 violates the Constitution. The district court agreed and held that § 4248âs civil commitment scheme could not withstand constitutional scrutiny. Comstock, 507 F.Supp.2d at 530-40.
With this background in mind, we turn to the question presented in this case: whether the Constitution grants Congress the authority to enact § 4248.
II.
In the exercise of their general police and parens patriae powers, the states have long controlled the civil commitment of the mentally ill. See, e.g., United States v. Sahhar, 56 F.3d 1026, 1029-30 (9th Cir. 1995); United States v. Cohen, 733 F.2d 128, 150 (D.C.Cir.1984) (en banc) (Mac-Kinnon, J., concurring) (â[The] care and commitment of the insane is, and has been, a uniquely State function.â); Note, Federal Hospitalization of Insane Defendants Under Section 1216 of the Criminal Code, 64 Yale L.J. 1070, 1070 (1955) (âPower over the general field of insanity resides exclusively in the states as parens patriae .... â). Unlike the states, the federal government has no general police or parens patriae power. United States v. Lopez, 514 U.S. 549, 566, 115 S.Ct. 1624, 131 L.Ed.2d 626 (1995).
Nonetheless, in the statute at issue here, Congress purports to grant the federal government broad civil commitment authority. 4 This raises a substantial constitutional question because the Constitution requires that a specific enumerated power support every statute enacted by Congress. Morrison, 529 U.S. at 607, 120 S.Ct. 1740. The Government does not argue to the contrary.
Yet the Government attempts to defend the validity of § 4248 largely by direct reliance on the Necessary and Proper Clause. U.S. Const, art. I, § 8, cl. 18. But that provision, by itself, creates no constitutional power; rather, it merely permits Congress â[t]o make all Laws which shall be necessary and proper for carrying into Execution ... all ... Powers *279 vested by this Constitution in the Government of the United States.... â Id. (emphasis added). Thus, to sustain § 4248 under the Necessary and Proper Clause, the Government must show that the statute is necessary to achieve ends within Congressâs enumerated powers. See Sabri v. United States, 541 U.S. 600, 605, 124 S.Ct. 1941, 158 L.Ed.2d 891 (2004).
Perhaps implicitly recognizing this deficiency in its Necessary and Proper Clause arguments, the Government also relies (albeit briefly) on the Commerce Clause. 5 Unlike the Necessary and Proper Clause, the Commerce Clause does vest Congress with enumerated constitutional power. Clearly, if we can uphold § 4248 as a valid exercise of Congressâ Commerce Clause powers, the statute lies within congressional authority. Accordingly, consistent with the âpresumption of constitutionality,â Morrison, 529 U.S. at 607, 120 S.Ct. 1740, that we afford every federal statute, we begin our analysis by addressing this question.
A.
The Commerce Clause empowers Congress â[t]o regulate Commerce ... among the several States.â U.S. Const, art. I, § 8, cl. 3.
Recent Supreme Court precedent provides substantial assistance in resolving the question of whether the Commerce Clause authorizes § 4248. First, in United States v. Lopez, the Court held that the Gun-Free School Zones Act (GFSZA) of 1990, which made possession of a firearm in a school zone a federal crime, exceeded Congressâs Commerce Clause power because it regulated neither commercial nor interstate activity. 514 U.S. at 551, 115 S.Ct. 1624. Then, in Morrison, the Court imposed further limits on Congressâs Commerce Clause power, holding unconstitutional a provision of the Violence Against Women Act (VAWA) that created a federal civil remedy for noneconomic sexual violence, because such crimes do not substantially affect interstate commerce. 529 U.S. at 601-02, 614-18, 120 S.Ct. 1740.
In these cases, the Court identified three specific areas that Congress could regulate pursuant to its Commerce Clause power: (1) the channels of interstate commerce, (2) instrumentalities of or persons and things in interstate commerce, and (3) activities that âsubstantially affectâ interstate commerce. See, e.g., Lopez, 514 U.S. at 558-59, 115 S.Ct. 1624. Like the statutes at issue in Lopez and Morrison, the statute challenged here, § 4248, contains no jurisdictional requirement limiting its application to commercial or interstate activities. Nor does the Government suggest that § 4248 targets the channels of interstate commerce or persons and things in interstate commerce. Therefore, we can uphold § 4248 under the Commerce Clause only if it regulates activities that âsubstantially affectâ interstate commerce. See Morrison, 529 U.S. at 609, 120 S.Ct. 1740.
Morrison forecloses any such argument. Indeed, § 4248 bears striking similarities to the VAWA provision struck down in Morrison. First, like VAWA, § 4248 provides a civil remedy aimed at the prevention of noneconomic sexual violence. The Morrison Courtâs rationale for rejecting *280 Commerce Clause authority for such a statute applies with equal force here:
The regulation and punishment of intrastate violence ... has always been the province of the States. Indeed, we can think of no better example of the police power, which the Founders denied the National Government and reposed in the States, than the suppression of violent crime and vindication of its victims.
Id. at 618-19, 120 S.Ct. 1740 (citations omitted).
Second, the target of the statute challenged here (sexual dangerousness) â no less than the target of the statute invalidated in Morrison (gender-motivated violence) â is ânot, in any sense of the phrase, economic activity.â Id. at 613, 120 S.Ct. 1740. Like the gender-motivated violence banned in Morrison, sexual dangerousness does not substantially affect interstate commerce. Indeed, unlike Morrison, the record here does not even contain any legislative findings to the contrary.
Supreme Court precedent thus compels the conclusion that § 4248 does not constitute a valid exercise by Congress of its Commerce Clause power. 6 To construe § 4248 as within such power would encroach on the police and parens patriae powers reserved to the sovereign states, conflating âwhat is truly national and what is truly local.â Id. at 617-18, 120 S.Ct. 1740; see also Cohen, 733 F.2d at 138 (Scalia, J.) (â â[A] Federal procedure for the commitment of the [mentally ill] would constitute an inappropriate interference with the balance of Federal and State powers.... [T]he care of the mentally ill is a task that uniquely belongs within the par-ens patriae powers of the States.â â (quoting H.R.Rep. No. 96-1396, at 561 (1980))).
Federal commitment of âsexually dangerous personsâ may well be â like the suppression of guns in schools or the redress of gender-motivated violence â a sound proposal as a matter of social policy. But policy justifications do not create congressional authority. Morrison, 529 U.S. at 627, 120 S.Ct. 1740. Hence § 4248 lies beyond Congressâs Commerce Clause authority. The Governmentâs apparent reluctance to rely on the Commerce Clause is thus understandable.
B.
What is less understandable is the Governmentâs heavy reliance on the Necessary and Proper Clause, standing alone, as a source of congressional power. Of course, as the Government contends at length, the Necessary and Proper Clause reaches broadly, but it does so only to effectuate powers specifically enumerated in the Constitution. See McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316, 414-21, 4 L.Ed. 579 (1819). The Necessary and Proper Clause simply does not â in and of itself â create any Congressional power. See Kinsella v. United States ex rel. Singleton, 361 U.S. 234, 247, 80 S.Ct. 297, 4 L.Ed.2d 268 (1960) (âThe [Necessary and Proper Clause] is *281 not itself a grant of power, but a caveat that the Congress possesses all the means necessary to carry out the specifically granted âforegoingâ powers of § 8 [of Article I of the Constitution.]â). Ordinarily, this would end our discussion of the Necessary and Proper Clause. But because the Governmentâs defense of § 4248 relies almost exclusively on that Clause, we briefly address each of its specific arguments on this point.
1.
The Governmentâs principal argument is that its ability to establish and maintain a âfederal criminal justice and penal systemâ somehow renders § 4248 necessary and proper and thus constitutional. See Brief of Appellant at 14, 20, 21, 30, 32, 34, 42; Reply Brief of Appellant at 2, 6, 7, 10, 16. The Government cites no precedent in support of this novel theory. Instead, the Government relies on a restatement provision setting forth common law principles on the responsibilities of custodians. See Brief of Appellant at 30 (quoting Restatement (Second) of Torts § 319 (1965)); Reply Brief of Appellant at 11-12 (same). In essence, the Government argues that because it may constitutionally imprison persons who violate federal criminal law, it can continue to confine such persons â even after they have served their sentences â if it believes them to be âsexually dangerous.â
This argument must fail. Of course, Congress may establish and run a federal penal system, as necessary and proper to the Article I power (usually the Commerce Clause) relied on to enact federal criminal statutes. And, consistent with its role in maintaining a penal system, the federal government possesses broad powers over persons during their prison sentences. But these powers are far removed from the indefinite civil commitment of persons after the expiration of their prison terms, based solely on possible future actions that the federal government lacks power to regulate directly. 7
The fact of previously lawful federal custody simply does not, in itself, provide Congress with any authority to regulate future conduct that occurs outside of the prison walls. For example, although the Government may regulate assaults occurring in federal prisons, the Government cannot criminalize all assaults committed by former federal prisoners. As the district court explained:
The fact of legitimate custody ... does not establish Congressional authority to provide for the commitment of a person after a person has completed a sentence for a federal crime, i.e., when the power to prosecute federal offenses is exhausted, when that person has not committed any misconduct while in custody, and where there has been no showing that the person is likely to engage in conduct *282 that Congress, as opposed to the states, actually has the authority to criminalize.
Comstock, 507 F.Supp.2d at 551.
2.
The Government next contends that § 4248 constitutes a necessary and proper exercise of its power to prevent âsex-related crimes.â Brief of Appellant at 36. But the federal government simply has no power to broadly regulate all sex-related crimes, as § 4248 purports to do.
Consistent with Congressâs limited powers, federal statutes regulating sex crimes are limited in number and breadth, specifically requiring a connection to interstate commerce, see, e.g., 18 U.S.C. § 2252(a)(2) (2006), or limiting their scope to the territorial jurisdiction of the United States, see, e.g., id. § 2243(a). In contrast, § 4248 targets âsexual dangerousnessâ generally, without any requirement that this undefined danger relate to conduct that the federal government may constitutionally regulate. Because most crimes of sexual violence violate state and not federal law, 8 many commitments under § 4248 would prevent conduct prohibited only by state law. Section 4248 thus sweeps far too broadly to be a valid effort to prevent federal criminal activity.
The principal case on which the Government relies for its argument to the contrary, United States v. Perry, 788 F.2d 100 (3d Cir.1986), actually offers it no support. Notably, at the outset, the Perry court recognized (as the Government fails to here) that a specific, enumerated federal power must support a federal civil commitment:
[T]he federal government may resort to civil commitment when such commitment is necessary and proper to the exercise of some specific federal authority. Congress may not, however, authorize commitment simply to protect the general welfare of the community at large.
Id. at 110 (emphasis added). Applying this test, Perry upheld the constitutionality of the Bail Reform Act of 1984, which authorizes pretrial detention only if a court finds a likelihood that the detainee will, if released, commit one of four specific federal offenses. Id. at 111. The Bail Reform Act therefore contained a clear connection between the pretrial detentions and the Governmentâs interest in preventing federal crime. 9
*283 In contrast, § 4248 contains no such connection: it does not refer to any federal crime, let alone require the Government to demonstrate that a person presents a risk of committing a specific federal crime. Indeed, under § 4248, the federal government may commit a person even though he has never been convicted by any courtâ state or federal â of any crime of sexual violence. Section 4248 only requires that the Government demonstrate that an individual in United States custody is âsexually dangerous,â which encompasses any âsexually violent conductâ â regardless of whether state or federal law criminalizes this conduct. See 18 U.S.C. § 4247(a)(6) (2006).
At its core, the Governmentâs argument attempts to âpile inference upon inferenceâ so as to âconvert congressional authority under the Commerce Clause to a general police power of the sort retained by the States.â Lopez, 514 U.S. at 567, 115 S.Ct. 1624. Were we to accept the Governmentâs logic, Congress could authorize the civil commitment of a person on a showing that he posed a general risk of any sexually violent conduct, even though not all, or even most, of this potential conduct violated federal law. This argument would convert the federal governmentâs limited power to criminalize narrow forms of sexual violence into the general power to regulate all sexual violence, including acts which violate no criminal statute. Congressional power does not reach so far.
3.
Finally, the Government maintains that the Necessary and Proper Clause justifies § 4248 because it retains the âpower to prosecuteâ all persons in its custody charged with criminal offenses. But the Government has already charged, tried, and convicted Comstock, Matherly, Vigil, and Revland of all alleged federal crimes; it retains no power to prosecute them.
Greenwood v. United States, 350 U.S. 366, 76 S.Ct. 410, 100 L.Ed. 412 (1956), on which the Government heavily relies, does not suggest, let alone hold, to the contrary. Rather, Greenwood simply upholds a statute that permits the federal civil commitment of a person charged with federal crimes but found incompetent to stand trial. Id. at 367-68, 375, 76 S.Ct. 410. To prevent âfrustrat[ion]â of federal prosecutions in such cases, Greenwood authorizes the commitment of these incompetent individuals, reasoning that they might someday regain competence and so be able to stand trial. Id. at 375, 76 S.Ct. 410 (âThe power that put [the accused] into [federal] custody â the power to prosecute for federal offenses â is not exhausted.â). 10 Fur *284 thermore, the statute upheld in Greenwood requires the Attorney General to determine that âsuitable arrangements for State custody and care of the person are not availableâ before the federal government can undertake any commitment. 18 U.S.C. § 4246(a) (2006) (emphasis added).
In sum, Greenwood only approved the federal civil commitment of persons who had been charged with federal crimes but found incompetent to stand trial, and for whom no state would take custody. Greenwood certainly did not approve the federal civil commitment of persons- â like Com-stock, Matherly, Vigil, and Revland â who have stood trial, been convicted, and fully served all federal prison sentences. 11 Accordingly, because no federal prosecution has been frustrated here, we cannot sustain § 4248 under Greenwood.
III.
For these reasons, we can only conclude that the district court correctly held § 4248 unconstitutional. The challengers have made a âplain showingâ that, in enacting § 4248, Congress exceeded its constitutional authority. Morrison, 529 U.S. at 607, 120 S.Ct. 1740.
Our holding, however, does not require that the Governmentâs legitimate policy concerns go unaddressed. If the federal government has serious concerns about the dangerousness of a person due to be released from federal prison, it can notify state authorities, who may use their well-settled police and parens patriae powers to pursue civil commitment under state law. See generally Kansas v. Hendricks, 521 U.S. 346, 117 S.Ct. 2072, 138 L.Ed.2d 501 (1997).
Moreover, if the relevant state authorities prove reluctant to take charge of such persons, the Government is not without recourse. The federal government may, for example, wield its spending power to encourage state action, see U.S. Const, art. I, § 8, cl. 1 (granting Congress the power to allocate funds to promote the âgeneral Welfareâ), by providing funding to state institutions for this purpose. Cf. South Dakota v. Dole, 483 U.S. 203, 209-12, 107 S.Ct. 2793, 97 L.Ed.2d 171 (1987). But Congressâs perceived need for the sort of civil commitment statute at issue here does not create constitutional power where none exists. See Morrison, 529 U.S. at 627, 120 S.Ct. 1740. Congress must instead seek alternative, constitutional means of achieving what may well be commendable objectives.
The power claimed by § 4248 â forcible, indefinite civil commitment â is among the most severe wielded by any government. The Framers, distrustful of such authority, reposed such broad powers in the states, limiting the national government to specific and enumerated powers. â[T]hat those limits may not be mistaken, or forgotten, the constitution is written.â Marbury v. Madison, 5 U.S. (1 Cranch) 137, 176, 2 L.Ed. 60 (1803). Section 4248 thus cannot be sustained as an exercise of Congressâs authority under the Commerce Clause or any other provision of the Constitution. *285 For these reasons, we affirm the judgment of the district court.
AFFIRMED
. Because we find § 4248 unconstitutional on this basis, we need not reach the other challenges to the statute and express no opinion on the district courtâs disposition of those issues.
. In contrast to the undefined commitment criteria of § 4248, many state civil commitment statutes related to "sexually dangerous persons" are more narrowly drawn. For example, a proceeding for civil commitment of a "sexually violent predatorâ under Virginia law cannot be commenced unless the person "has been convicted of a sexually violent offense.â Va.Code Ann. § 37.2-900 (2008). The statute specifically defines those offenses.
. The Attorney General has certified, under § 4248, more than 60 persons in the Eastern District of North Carolina alone, all of whom (as of this writing) remain in the federal prison complex in Butner, North Carolina. With one exception (Shane Catron, whose case we address in footnote 10), each of these persons had already served all, or almost all, of his prison term when the Attorney General certified him for this additional confinement. See Brief of Appellee at Appendix A; see also United States v. Wilkinson, No. 07-12061-MLW, 2008 WL 427295, at *1-3 (D.Mass. Feb.14, 2008) (finding that all of the § 4248 *278 eases filed in the District of Massachusetts involved certifications "just before the expiration of the [prisoner's] sentenceâ and urging the government to end this practice).
. Section 4248 is not Congress's first attempt to assert federal power over civil commitment â but prior Attorneys General have concluded that the Constitution does not authorize such broad measures. In 1857, for example, Congress enacted a statute authorizing the hospitalization of incompetents charged with federal crimes. Act of Feb. 15, 1857, ch. 36, § 5, 11 Stat. 157, 158. But the Attorney General â adhering to precisely the same constitutional limits at issue in this case â concluded that the federal government could apply this statute only to persons within exclusive federal jurisdiction (e.g., residents of the District of Columbia and members of the military). 17 Op. Att'y Gen. 211 (1881). And, in 1874, Congress sought to provide, as § 4248 does, for the hospitalization of federal convicts found to be insane at the termination of their sentences. Act of June 23, 1874, ch. 465, § 2, 18 Stat. 251, 251-52. The Attorney General concluded that the federal government could not constitutionally detain a federal prisoner after the termination of his sentence, 30 Op. Att'y Gen. 569 (1916), and Congress codified this limitation in 1930. Act of May 13, 1930, ch. 254, § 6, 46 Stat. 270, 271.
. The Government barely mentions the Commerce Clause in its lengthy briefs. But when questioned at oral argument â after initially asserting that a "variety of [enumerated] powersâ supported the challenged statute â the Government could identify only the Commerce Clause as the specific enumerated constitutional power that authorized enactment of § 4248.
. As the Government acknowledges, nothing in the Supreme Courtâs most recent Commerce Clause opinion, Gonzales v. Raich, 545 U.S. 1, 125 S.Ct. 2195, 162 L.Ed.2d 1 (2005), alters the core holding in Morrison that Congress lacks authority to regulate noneconomic sexual violence. The Raich Court sustained the drug prohibitions of the Controlled Substances Act (CSA) as applied to the intrastate cultivation and use of medical marijuana. Id. at 13, 32-33, 125 S.Ct. 2195. Relying on the rationale of Wickard v. Filburn, 317 U.S. 111, 63 S.Ct. 82, 87 L.Ed. 122 (1942), the Court reasoned that Congress could regulate this purely local activity as part of regulating "an economic class of activities that have a substantial effect on interstate commerce.â Raich, 545 U.S. at 17, 125 S.Ct. 2195 (internal quotations omitted). In contrast to the CSA, § 4248 constitutes no part of a "comprehensiveâ legislative scheme that targets interstate markets. Id. at 22, 125 S.Ct. 2195.
. We further note that the expansive view of "custodyâ that the Government itself has urged in other § 4248 cases belies its contention that § 4248 constitutes a limited, necessary extension of the federal penal system. For example, in United States v. Shields, the Government maintained that § 4248 requires only that a person is âin custodyâ of the Bureau of Prisons, not that this custody is lawful. See Government's Mem. in Opp'n to Mot. to Dismiss at 1-3, United States v. Shields, No. 07-12056 (D.Mass. Nov. 13, 2007). Similarly, in a case currently on appeal before the Seventh Circuit, the Government argues that § 4248 validly applies to persons whom the federal government has never convicted of a crime â a rationale that would extend § 4248âs reach to material witnesses, civil contempt detainees, and individuals in immigration detention. See United States v. Hernandez-Arenado, No. 08-278, 2008 WL 2373747, at *3-5 (S.D.Ill. June 9, 2008). These arguments starkly conflict with the Governmentâs attempt here to justify § 4248 as a narrow exercise of federal penal power.
. Even a cursory review of federal and state prison statistics demonstrates this fact. In 2004, states had in their custody approximately 153,800 prisoners convicted of rape or other sexual assault. See William J. Sabol et al., U.S. Depât of Justice, Prisoners in 2006, at 24 app. tbl.9 (2007), available at http://www. ojp.gov/bjs/pub/pdf/p06.pdf. This number is approximately equal to the total number of persons in federal prison for any crime. See id. at 2 tbl.l (indicating approximately 188,-000 total federal inmates in 2005). Those convicted of sexual crimes constitute a very small percentage of the federal total. See Bureau of Justice Statistics, U.S. Depât of Justice, Compendium of Federal Justice Statistics, 2003, at 62 tbl.4.2 (2005), available at http://www.ojp.usdoj.gov/bjs/pub/pdi/cfjs03. pdf (indicating that federal convictions for violent sexual offenses, "obscene material,â and "non-violent sex offenses,â together, constituted less than 2% of all federal convictions).
. United States v. Plotts, 347 F.3d 873 (10th Cir.2003), offers the Government even less support. Plotts held a statute requiring that individuals convicted of federal crimes provide DNA samples was constitutional under Congressâs power to âfashion penalties for the violation of valid federal laws," or because of its power "to aid the Executive in prosecuting those who ... violate federal criminal laws." Id. at 879 (emphasis added). Neither of these rationales supports § 4248, because commitment under § 4248 constitutes no part of a personâs âpenalt[y]â or "prosecution]â for the violation of "federal criminal laws.â
. For example, a federal judge found Shane Catron â the fifth person who challenges § 4248 here â incompetent to stand trial before the Government could prosecute him for his alleged criminal offenses. This frustrated the Governmentâs power to prosecute Catron. Thus, as Catron concedes, § 4246 (the statute at issue in Greenwood) empowers the Government to certify and detain him in a federal facility until he regains competence. Had the Government held to its original course of committing Catron pursuant to § 4246, its actions would lie within its constitutional authority. But, for unexplained reasons, the Government chose to withdraw its § 4246 certification of Catron and instead certified him pursuant to § 4248. The seemingly unique circumstances of Catron's case differ greatly from those applicable to the four other appellees in this case, and to all of the more than 60 other individuals committed under § 4248 in this circuit. Because no party asks us to bifurcate Catronâs unique challenge to § 4248, we decline to do so. As the Supreme Court has noted, when the parties do not ask for such "finely drawnâ relief, we need not embark on such a course. See Ayotte v. Planned Parenthood of N. New Eng., 546 U.S. 320, 330-31, 126 S.Ct. 961, 163 L.Ed.2d 812 (2006). We note that § 4246 also purports to allow the federal government to confine indefinitely persons in federal custody whose sen *284 tences have expired. But that provision was neither at issue nor addressed by the Supreme Court in Greenwood; similarly, it is not at issue here and we too decline to address it.
. Although the Government notes in passing that Comstock, Matherly, Vigil, and Revland remain subject to supervised release, it does not allege that they have violated the terms of supervised release or any other federal law. Of course, the Government has no unexhaust-ed power to prosecute a former federal prisoner simply because he could violate a term of his supervised release; any person could violate federal law.
