From the Umpqua Community College “security page”:
Possession, use, or threatened use of firearms (including but not limited to BB guns, air guns, water pistols, and paint guns) ammunition, explosives, dangerous chemicals, or any other objects as weapons on college property, except as expressly authorized by law or college regulations, is prohibited.
Possession of knives with a blade longer than 4 is prohibited.
Brandishing weapons is prohibited.
Misuse of personal defensive weapons e.g., pepper spray, etc. is prohibited. The owner is responsible and accountable for any misuse of these devices.
But do they allow homemade “clocks” that resemble bombs?
