Sorry if this was already answered: I did a search and came up with nothing related. I'm a high school teacher, and have a PA concealed carry permit (LTCF). I was reading the US Code Title 18,922 where it says "(q) (2) (A) It shall be unlawful for any individual knowingly to possess a firearm that has moved in or that otherwise affects interstate or foreign commerce at a place that the individual knows, or has reasonable cause to believe, is a school zone. (B) Subparagraph (A) does 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 obtains 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;" It sounds like I can legally carry concealed into the school building? I always thought public schools were gun-free zones since the Columbine shooting? Thanks.
