SCHOOL ZONE.--
<< 18 USCA § 922 >>
(1) IN GENERAL.--Section 922 of title 18, United States Code, is amended by adding at the end
the following new subsection:
"(q)(1)(A) It shall be unlawful for any individual knowingly to possess a firearm at a place that the
individual knows, or has reasonable cause to believe, is a school zone.
"(B) Subparagraph (A) shall not apply to the possession of a firearm--
"(i) on private property not part of school grounds;
"(ii) if the individual possessing the firearm is licensed to do so by the State in which the school
zone is located or a political subdivision of the State, and the law of the State or political
subdivision requires that, before an individual obtain such a license, the law enforcement
authorities of the State or political subdivision verify that the individual is qualified under law to
receive the license;
One could argue that one would have to know a place was a school in order to be in violation.
One could argue that a purchase permit is a license to possess a firearm (since the element for the exemption is a background check.).
In this particular instance there is an argument that a public library supported by municipal funds would qualify as a school (regardless of the claimed ownership of the property. Research the definition of a school zone in both state and federal laws).
