It was against school rules for the hero to carry pepper spray. Doing what is right trumps the rules.
Yup. Prohibited by the libtards as that college: “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.
