That may be the case (not sure what the school’s code is), but as I understand it from listening non-stop on this for almost an hour driving home yesterday, SPU routinely does security/safety drills, and this young man (other reports say he was part of the school’s ROTC program), was said to be the “student building monitor” and I’ve heard him described as the student “security monitor”. If he was the student building monitor and/or security monitor, perhaps they allowed him to carry pepper spray - don’t know, just a thought.
SPU prohibits “13. Possession, use or display on University property of any firearms, weapons, fireworks, live ammunition, incendiary devices, or other items that are potentially hazardous to members of the campus community.” Pepper spray is definitely “potentially hazardous,” ergo prohibited.
