Under the theories that the Government presents in support of §922(q), it is difficult to perceive any limitation on federal power, even in areas such as criminal law enforcement or education where States historically have been sovereign. Thus, if we were to accept the Government's arguments, we are hard pressed to posit any activity by an individual that Congress is without power to regulate.
The Constitution requires a distinction between what is truly national and what is truly local, and there is no better example of the police power, which the Founders undeniably left reposed in the States and denied the central government, than the suppression of violent crime and vindication of its victims. Congress therefore may not regulate noneconomic, violent criminal conduct based solely on the conduct’s aggregate effect on interstate commerce
Section 922(q) is a criminal statute that by its terms has nothing to do with "commerce" or any sort of economic enterprise, however broadly one might define those terms. [n.3] Section 922(q) is not an essential part of a larger regulation of economic activity
UNITED STATES v. MORRISON et al.
"To uphold the Government's contentions here, we would have to pile inference upon inference in a manner that would bid fair to convert congressional authority under the Commerce Clause to a general police power of the sort retained by the States. Admittedly, some of our prior cases have taken long steps down that road, giving great deference to congressional action. See supra, at 8. The broad language in these opinions has suggested the possibility of additional expansion, but we decline here to proceed any further. To do so would require us to conclude that the Constitution's enumeration of powers does not presuppose something not enumerated, cf. Gibbons v. Ogden, supra, at 195, and that there never will be a distinction between what is truly national and what is truly local, cf. Jones & Laughlin Steel, supra, at 30. This we are unwilling to do.
