My interpretation of ORS 166.370(3) is that persons authorized by sub-sections a. (LEOs), b. (assisting police), c. (active military or reserve), d. (CWL holders), e. (by agency in charge of building) & f (employee of Dept of Ag) are allowed to carry a firearm on school grounds. My interpretation of ORS 166.370(5) is that even if you have a CWL, you are not allowed to discharge your firearm on school grounds, even in self-defense or in the defense of a third person. If you do, you can be convicted of a Class C felony. This is because a person with a CWL is not listed as one of the authorized reasons within 166.370(5)(b) I propose that ORS 166.370 be amended.
