Actually the federal law does NOT apply to CHL holders due to an exemption in the federal law and the way Oregon state law is written.
USC Title 18, ss 922 says you can't carry a firearm "in a school zone" UNLESS you are licensed by the state to carry the firearm. The Oregon CHL is a license, issued by this state, which licenses the CHL holder to possess firearms (long gun or handgun not differentiated, see ORS 166-360 and 370). In this state, with a CHL, you are licensed to carry a FIREARM on school grounds by nature of those ORS.
Title 18, USC, ss 922, q, (1), originally enacted in 1990 but overturned by the US Supreme Court in 1995, was re enactd in 1996 but with far less "school zone" BS than the original.
18, USC, ss 921, defines school zone as 1000 feet and defines school as "primary or secondary" (which is K-12). Universities, Colleges, and professional schools ARE NOT primary or secondary education, they are "post secondary education".
I have pasted in the text from USC 18, 922 below, in part, (it's a really long one on a ton of BS crap that the congress seems to think they have the power to regulate because of the "interstate commerce clause"). Kind of like that gives them the power to regulate our health care and anything else they want to regulate just by saying "commerce clause".
If you want to read the entire section (it deals with transfers, intestate transfers, possession in "school zones", etc. There are also a few more exemptions after the point I stopped cutting. And Colleges and Universities do not fall under the gun free school zones due to ss 921 definitions. Without a license you can't be on their grounds or within 1000 feet but with an Oregon CHL you are exempt and, again, Colleges and Universities are NOT covered in 18 USC, 922. Only K-12 schools.
Pertinent Portion of US Code Title 18, ss 922, 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;
Know the law....in and out!!!!!!
In my opinion, 166.210 covers the definitions for a CHL (166.291), which it defines a handgun. 166.291 also uses the word handgun specifically, does not say anything about long guns. I see that Oregon law doesn't care about a long gun in a school zone if you are licensed. But federal law (in my opinion) overrides state law, and states that you must be licensed to carry that firearm, which CHL holders are not licensed for anything but a handgun.
