Gun-Free zones were found unconstitutional by the Supreme Court in 1995!!!!

The Gun-Free School Zones Act of 1990 was originally passed as section 1702 of the Crime Control Act of 1990. It added 18 U.S.C. § 922(q).

The Supreme Court of the United States subsequently held that the Act was an unconstitutional exercise of Congressional authority under the Commerce Clause of the United States Constitution in United States v. Lopez, 514 U.S. 549 (1995). This was the first time in over half a century that the Supreme Court limited Congressional authority to legislate under the Commerce Clause.

Following the Lopez decision, President Clinton's Attoney General Janet Reno proposed changes to 18 U.S.C. § 922(q) that were adopted (or "concealed" and "widely ignored" as one author put it) in section 657 of the Omnibus Consolidated Appropriations Act of 1997, Pub.L. 104-208, 110 Stat. 3009, enacted September 30, 1996.[5] These minor changes required that the firearm in question "has moved in or otherwise affects interstate commerce".

As nearly all firearms have moved in Interstate Commerce at some point in their lives, critics assert this was merely a legislative tactic to circumvent the Supreme Court's ruling.
