It shouldn't be hard to under that statement, it's pretty straightforward

You gave a non clear example and so I asked you to give me a real world application. If you have no real world applications then don't squander about babbling just to sound smart.

What law? Is this data present anywhere?

Are you seriously questioning the existence of the law?

The Gun-Free School Zones Act:

(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;

(iii) that is—

(I) not loaded; and

(II) in a locked container, or a locked firearms rack that is on a motor vehicle;

(iv) by an individual for use in a program approved by a school in the school zone;

(v) by an individual in accordance with a contract entered into between a school in the school zone and the individual or an employer of the individual;

(vi) by a law enforcement officer acting in his or her official capacity; or

(vii) that is unloaded and is possessed by an individual while traversing school premises for the purpose of gaining access to public or private lands open to hunting, if the entry on school premises is authorized by school authorities.

(3) (A) Except as provided in subparagraph (B), it shall be unlawful for any person, knowingly or with reckless disregard for the safety of another, to discharge or attempt to discharge a firearm that has moved in or that otherwise affects interstate or foreign commerce at a place that the person knows is a school zone.

(B) Subparagraph (A) does not apply to the discharge of a firearm—

(i) on private property not part of school grounds;

(ii) as part of a program approved by a school in the school zone, by an individual who is participating in the program;

(iii) by an individual in accordance with a contract entered into between a school in a school zone and the individual or an employer of the individual; or

(iv) by a law enforcement officer acting in his or her official capacity.

(4) Nothing in this subsection shall be construed as preempting or preventing a State or local government from enacting a statute establishing gun free school zones as provided in this subsection.

That should make it blatantly clear to you that the law is present. I was under the assumption that you knew this. There is usually a sticker on the window that even alludes to the law. This is something you should be aware of.

Sounds like police dooty to me.

I don't think you actually understand the criteria here. I don't think you are taking this serious unless I am terrible at looking for literary cues.
